+---
+
+# Add Tracing Spans to Clojure Code
+
+This skill helps you add OpenTelemetry (OTel) tracing spans to the Metabase backend codebase using the custom `tracing/with-span` macro.
+
+## Reference Files
+
+- `src/metabase/tracing/core.clj` - `with-span` macro, group registry, SDK lifecycle, `best-effort-sanitize-sql`, Pyroscope integration
+- `src/metabase/task/impl.clj` - `defjob` macro that wraps Quartz jobs with root spans
+- `.clj-kondo/config/modules/config.edn` - Module boundary configuration
+
+## Module Architecture
+
+The tracing module has a deliberately minimal API surface. **Only 2 namespaces are public** (listed in `:api` in the module config):
+
+| Namespace | Role | Status |
+|---|---|---|
+| `tracing.core` | Primary API: `with-span`, groups, SDK lifecycle, Pyroscope, MDC, `best-effort-sanitize-sql` | **Public API** |
+| `tracing.init` | Side-effect loader for `quartz` and `settings` | **Public API** (init convention) |
+| `tracing.attributes` | `best-effort-sanitize-sql` implementation (re-exported via `tracing.core`) | Internal |
+| `tracing.settings` | Setting definitions (`MB_TRACING_*` env vars) | Internal |
+| `tracing.quartz` | Quartz JDBC proxy + JobListener | Internal |
+
+**Rules:**
+- Only require `[metabase.tracing.core :as tracing]` from outside the module. `tracing/best-effort-sanitize-sql` and all other public functions are available from this single namespace.
+- Do not add new API namespaces. Add new public functions to `tracing.core` instead.
+- Do not require internal namespaces (`tracing.attributes`, `tracing.settings`, `tracing.quartz`) from outside the module.
+- `:uses :any` on the `core` module does NOT bypass the target module's `:api` check — internal namespaces are still enforced.
+
+### Cyclic Dependency Avoidance
+
+`tracing/core.clj` is required by many modules across the codebase. It **must NOT** compile-time require `tracing.settings`, as this creates transitive cyclic load dependencies (e.g., `settings/core -> tracing/settings -> tracing/core -> events/impl -> events/core`).
+
+Instead, `tracing/core.clj` uses `requiring-resolve` for settings access:
+
+```clojure
+;; CORRECT — lazy runtime resolution, no compile-time dependency
+((requiring-resolve 'metabase.tracing.settings/tracing-enabled))
+
+;; WRONG — creates cyclic load dependency
+(require '[metabase.tracing.settings :as settings])
+(settings/tracing-enabled)
+```
+
+External library namespaces (clj-otel API, SDK, exporters) are safe to require normally — they don't participate in Metabase namespace cycles.
+
+**Important:** `requiring-resolve` must use **literal quoted symbols**. Kondo hooks validate that `required-namespaces` are all simple symbols, so dynamic construction fails:
+
+```clojure
+;; CORRECT — literal quoted symbol
+(requiring-resolve 'metabase.tracing.settings/tracing-endpoint)
+
+;; WRONG — kondo hook rejects this: "Assert failed: (every? simple-symbol? required-namespaces)"
+(requiring-resolve (symbol "metabase.tracing.settings" "tracing-endpoint"))
+```
+
+## Quick Checklist
+
+When adding tracing spans:
+
+- [ ] Module has `tracing` in its `:uses` set in `.clj-kondo/config/modules/config.edn`
+- [ ] Added `[metabase.tracing.core :as tracing]` to ns requires (alphabetically sorted)
+- [ ] Span wraps a meaningful I/O boundary (not pure computation)
+- [ ] Group matches the domain (check `src/metabase/tracing/core.clj` for registered groups; add a new one if none fit)
+- [ ] Span name follows dot-notation convention (`"domain.subsystem.operation"`)
+- [ ] Attributes use namespaced keywords (`:search/query-length`, `:db/id`)
+- [ ] No sensitive data in attributes (use `best-effort-sanitize-sql` for HoneySQL, never raw SQL)
+- [ ] No new tracing namespaces created (add to `tracing.core` instead)
+- [ ] No `DO_NOT_ADD_NEW_FILES_HERE.txt` violations in the target directory
+- [ ] Run `clj-kondo --lint <files>` to verify 0 errors, 0 warnings
+- [ ] Add or update tests in the corresponding `test/` path (see Testing section below)
+- [ ] Run tests: `clojure -X:dev:test :only <test-ns>`
+
+## The `with-span` Macro
+
+```clojure
+(tracing/with-span group span-name attrs & body)
+```
+
+- **group** - A keyword selecting which trace group this span belongs to (e.g., `:tasks`, `:sync`)
+- **span-name** - A string identifying the span in traces (e.g., `"search.execute"`)
+- **attrs** - A map of span attributes (e.g., `{:db/id 42}`)
+- **body** - The code to execute inside the span
+
+**When disabled:** zero overhead -- single atom deref + boolean check, body runs directly.
+**When enabled:** creates OTel span AND injects `trace_id`/`span_id` into Log4j2 MDC for log-to-trace correlation.
+
+## Trace Groups
+
+Groups are registered in `src/metabase/tracing/core.clj`. Check that file for the current list. The general rule: **match the group to the domain, not the call site.** If code runs inside a Quartz job but is logically search work, use `:search`, not `:tasks`.
+
+To add a new group:
+
+```clojure
+;; In src/metabase/tracing/core.clj
+(register-group! :my-domain "Description of what this covers")
+```
+
+Users enable groups via `MB_TRACING_GROUPS=tasks,search,sync` (comma-separated, or `"all"`).
+
+## Naming Conventions
+
+### Span Names
+
+Use dot-separated hierarchical names: `"domain.subsystem.operation"`. The domain prefix should match the group name:
+
+```
+search.execute              -- `:search` group
+sync.fingerprint.table      -- `:sync` group
+task.session-cleanup.delete -- `:tasks` group
+db-app.collection-items     -- `:db-app` group
+```
+
+### Attributes
+
+Use namespaced keywords. The namespace groups related attributes:
+
+```clojure
+:db/id              -- Database ID (integer)
+:db/engine          -- Database engine name (string)
+:db/statement       -- Sanitized SQL (string, via best-effort-sanitize-sql)
+:search/engine      -- Search engine name (string)
+:search/query-length -- Query string length (integer)
+:sync/table         -- Table name (string)
+:sync/step          -- Sync step name (string)
+:task/name          -- Task name (string)
+:http/method        -- HTTP method (string)
+:http/url           -- Request URL (string)
+```
+
+Invent new namespaced attributes as needed (e.g., `:pulse/id`, `:transform/count`). Keep values as primitives (strings, numbers, booleans) -- no maps or collections.
+
+## Step-by-Step: Adding a Span
+
+### 1. Check module boundaries
+
+Look up the module for your namespace in `.clj-kondo/config/modules/config.edn`. If `tracing` is not in the module's `:uses` set, add it (keep alphabetically sorted):
+
+```edn
+my-module
+{:team "MyTeam"
+ :uses #{analytics config tracing util}}
+```
+
+### 2. Add the require
+
+```clojure
+(ns metabase.my-module.thing
+  (:require
+   [metabase.tracing.core :as tracing]
+   [metabase.util :as u]))
+```
+
+`best-effort-sanitize-sql` is available from `tracing.core` — no additional require needed.
+
+### 3. Identify the I/O boundary
+
+Only wrap code at **meaningful I/O boundaries**:
+
+**DO trace:**
+- External API calls (embedding APIs, metabot, webhooks)
+- Database queries (both app DB and user DB)
+- Network requests (HTTP calls to external services)
+- Heavy batch processing (batch indexing, batch embedding)
+- Top-level orchestration functions that coordinate multiple sub-operations
+
+**DO NOT trace:**
+- Pure computation (sorting, filtering, mapping)
+- Simple single-row lookups (`t2/select-one :model/Setting :key k`)
+- Every function in a call chain (only boundaries matter)
+- Trivial operations (string formatting, hash calculations)
+
+### 4. Wrap with `with-span`
+
+```clojure
+;; Simple span (no attributes needed)
+(tracing/with-span :search "search.init-index" {}
+  (do-expensive-thing))
+
+;; Span with static attributes
+(tracing/with-span :sync "sync.fingerprint.table"
+                   {:db/id (:db_id table)
+                    :sync/table (:name table)}
+  (fingerprint-fields! table fields))
+
+;; Span with computed attributes
+(tracing/with-span :search "search.execute"
+                   {:search/engine       (name (:search-engine ctx))
+                    :search/query-length (count (:search-string ctx))}
+  (search.engine/results ctx))
+
+;; Span with sanitized SQL (for dynamic HoneySQL queries)
+(let [hsql {:delete-from [(t2/table-name :model/Session)]
+            :where [:< :created_at oldest-allowed]}]
+  (tracing/with-span :tasks "task.session-cleanup.delete"
+                     {:db/statement (tracing/best-effort-sanitize-sql hsql)}
+    (t2/query-one hsql)))
+
+;; Sub-spans breaking a function into I/O phases
+(let [embedding (tracing/with-span :search "search.semantic.embedding"
+                                   {:search.semantic/provider (:provider model)}
+                  (get-embedding model search-string))
+      results   (tracing/with-span :search "search.semantic.db-query" {}
+                  (into [] xform reducible))]
+  (process results))
+
+;; Per-item iteration spans
+(doseq [e (search.engine/active-engines)]
+  (tracing/with-span :search "search.ingestion.update" {:search/engine (name e)}
+    (search.engine/update! e batch)))
+```
+
+### 5. Add tests
+
+Create or update tests in the corresponding `test/` path. Follow the patterns in existing tracing tests:
+
+- **Reference tests:** `test/metabase/tracing/quartz_test.clj`, `test/metabase/server/middleware/trace_test.clj`
+- Use `tracing/init-enabled-groups!` / `tracing/shutdown-groups!` with `try`/`finally` to manage group lifecycle
+- Test both enabled and disabled paths (verify zero overhead when group is off)
+- Use `reify` mocks for Java interfaces (Connection, PreparedStatement, JobListener, etc.)
+- Add `(set! *warn-on-reflection* true)` and type-hint proxy/reify calls to avoid reflection warnings
+
+```clojure
+(deftest my-span-enabled-test
+  (testing "when group is enabled, span is created"
+    (try
+      (tracing/init-enabled-groups! "my-group" "INFO")
+      ;; ... test that span behavior occurs ...
+      (finally
+        (tracing/shutdown-groups!)))))
+
+(deftest my-span-disabled-test
+  (testing "when group is disabled, code runs without tracing"
+    (tracing/shutdown-groups!)
+    ;; ... test that code still works, no wrapping applied ...
+    ))
+```
+
+### 6. Lint and run tests
+
+```bash
+# Lint modified source and test files — expect 0 errors, 0 warnings
+clj-kondo --lint path/to/modified/file.clj path/to/test/file.clj
+
+# Run tests (requires Java 21+)
+  clojure -X:dev:test :only my-ns.test-ns
+```
+
+Expect: all tests pass, 0 failures, 0 errors, no reflection warnings from your files.
+
+## Sanitizing SQL for Attributes
+
+When including SQL in span attributes, **always** use `tracing/best-effort-sanitize-sql`. This converts HoneySQL maps to parameterized SQL strings where values become `?` placeholders -- no data leaks.
+
+```clojure
+(let [hsql {:delete-from [:core_session]
+            :where [:< :created_at some-timestamp]}]
+  (tracing/with-span :tasks "task.cleanup.delete"
+                     {:db/statement (tracing/best-effort-sanitize-sql hsql)}
+    (t2/query-one hsql)))
+;; Trace attribute: db/statement = "DELETE FROM core_session WHERE created_at < ?"
+```
+
+**Rules:**
+- Never put raw SQL strings or user-provided values in attributes
+- Use `best-effort-sanitize-sql` only for app DB (HoneySQL) queries
+- For external/user DB queries, trace only timing and counts, not SQL content
+
+## Defjob and Root Spans
+
+The `defjob` macro in `metabase.task.impl` automatically wraps every Quartz job with a `:tasks` root span:
+
+```clojure
+(task/defjob ^{DisallowConcurrentExecution true} SessionCleanup [_]
+  (cleanup-sessions!))
+;; Automatically creates span: "task.SessionCleanup" {:task/name "SessionCleanup"}
+```
+
+You do NOT need a root span inside `defjob` bodies. Add **child spans** for I/O inside the job.
+
+For code on plain `Thread`s (not Quartz), add the root span manually:
+
+```clojure
+(defn init! []
+  (tracing/with-span :search "search.task.init" {}
+    (search/init-index!)))
+```
+
+## What NOT to Do
+
+### Span Usage Mistakes
+
+```clojure
+;; WRONG - pure computation, no I/O
+(tracing/with-span :search "search.format-results" {}
+  (map format-result results))
+
+;; WRONG - trivial single-row lookup
+(tracing/with-span :db-app "db-app.get-setting" {}
+  (t2/select-one :model/Setting :key "my-setting"))
+
+;; WRONG - raw SQL in attributes (data leak)
+(tracing/with-span :tasks "task.cleanup" {:db/statement raw-sql-string}
+  (execute! raw-sql-string))
+
+;; WRONG - wrong group (search work should use :search, not :tasks)
+(tracing/with-span :tasks "search.execute" {} ...)
+
+;; WRONG - redundant nesting (do-search already has a span)
+(tracing/with-span :search "search.process" {}
+  (let [results (do-search ctx)]
+    (tracing/with-span :search "search.format" {}
+      (format-results results))))
+```
+
+### Architecture Mistakes
+
+```clojure
+;; WRONG - creating a new tracing namespace
+(ns metabase.tracing.my-feature ...)
+
+;; WRONG - requiring internal tracing namespaces from outside the module
+(ns metabase.my-module.thing
+  (:require [metabase.tracing.attributes :as trace-attrs]      ;; internal!
+            [metabase.tracing.settings :as tracing.settings]   ;; internal!
+            [metabase.tracing.quartz :as tracing.quartz]))     ;; internal!
+
+;; WRONG - adding compile-time requires to tracing/core.clj for settings or SDK
+;; This creates cyclic load dependencies because tracing/core is widely required
+(ns metabase.tracing.core
+  (:require [metabase.tracing.settings :as settings]))  ;; causes cycle!
+
+;; WRONG - dynamic symbol construction with requiring-resolve (kondo rejects it)
+(requiring-resolve (symbol "metabase.tracing.settings" "tracing-enabled"))
+```
+
+## Configuration
+
+All settings are env-var-only (defined in `src/metabase/tracing/settings.clj`):
+
+```bash
+# Core
+MB_TRACING_ENABLED=true              # Enable tracing (default: false)
+MB_TRACING_ENDPOINT=host:4317        # OTLP collector endpoint (default: http://localhost:4317)
+MB_TRACING_GROUPS=tasks,search,sync  # Comma-separated groups or "all" (default: all)
+MB_TRACING_SERVICE_NAME=metabase     # Service name in traces (default: hostname)
+MB_TRACING_LOG_LEVEL=DEBUG           # Log threshold for traced threads: TRACE/DEBUG/INFO (default: INFO)
+
+# Batch span processor tuning
+MB_TRACING_MAX_QUEUE_SIZE=2048       # Max spans queued for export; drops when full (default: 2048)
+MB_TRACING_EXPORT_TIMEOUT_MS=10000   # Max wait for batch export to complete (default: 10000)
+MB_TRACING_SCHEDULE_DELAY_MS=5000    # Delay between consecutive batch exports (default: 5000)
+```

+description: Evaluate Clojure code via nREPL using clj-nrepl-eval. Use this when you need to test code, check if edited files compile, verify function behavior, or interact with a running REPL session.
+---
+
+# Clojure REPL Evaluation
+
+## When to Use This Skill
+
+Use this skill when you need to:
+- **Verify that edited Clojure files compile and load correctly**
+- Test function behavior interactively
+- Check the current state of the REPL
+- Debug code by evaluating expressions
+- Require or load namespaces for testing
+- Validate that code changes work before committing
+
+## How It Works
+
+The `clj-nrepl-eval` command evaluates Clojure code against an nREPL server. **Session state persists between evaluations**, so you can require a namespace in one evaluation and use it in subsequent calls. Each host:port combination maintains its own session file.
+
+## Instructions
+
+### 0. Discover and select nREPL server
+
+First, discover what nREPL servers are running in the current directory:
+
+```bash
+clj-nrepl-eval --discover-ports
+```
+
+This will show all nREPL servers (Clojure, Babashka, shadow-cljs, etc.) running in the current project directory.
+
+**Then use the AskUserQuestion tool:**
+
+- **If ports are discovered:** Prompt user to select which nREPL port to use:
+  - **question:** "Which nREPL port would you like to use?"
+  - **header:** "nREPL Port"
+  - **options:** Present each discovered port as an option with:
+    - **label:** The port number
+    - **description:** The server type and status (e.g., "Clojure nREPL server in current directory")
+  - Include up to 4 discovered ports as options
+  - The user can select "Other" to enter a custom port number
+
+- **If no ports are discovered:** Prompt user how to start an nREPL server:
+  - **question:** "No nREPL servers found. How would you like to start one?"
+  - **header:** "Start nREPL"
+  - **options:**
+    - **label:** "deps.edn alias", **description:** "Find and use an nREPL alias in deps.edn"
+    - **label:** "Leiningen", **description:** "Start nREPL using 'lein repl'"
+  - The user can select "Other" for alternative methods or if they already have a server running on a specific port
+
+IMPORTANT: IF you start a REPL do not supply a port let the nREPL start and return the port that it was started on.
+
+### 1. Evaluate Clojure Code
+
+> Evaluation automatically connects to the given port
+
+Use the `-p` flag to specify the port and pass your Clojure code.
+
+**Recommended: Pass code as a command-line argument:**
+```bash
+clj-nrepl-eval -p <PORT> "(+ 1 2 3)"
+```
+
+**For multiple expressions (single line):**
+```bash
+clj-nrepl-eval -p <PORT> "(def x 10) (+ x 20)"
+```
+
+**Alternative: Using heredoc (may require permission approval for multiline commands):**
+```bash
+clj-nrepl-eval -p <PORT> <<'EOF'
+(def x 10)
+(+ x 20)
+EOF
+```
+
+**Alternative: Via stdin pipe:**
+```bash
+echo "(+ 1 2 3)" | clj-nrepl-eval -p <PORT>
+```
+
+### 2. Display nREPL Sessions
+
+**Discover all nREPL servers in current directory:**
+```bash
+clj-nrepl-eval --discover-ports
+```
+Shows all running nREPL servers in the current project directory, including their type (clj/bb/basilisp) and whether they match the current working directory.
+
+**Check previously connected sessions:**
+```bash
+clj-nrepl-eval --connected-ports
+```
+Shows only connections you have made before (appears after first evaluation on a port).
+
+### 3. Common Patterns
+
+**Require a namespace (always use :reload to pick up changes):**
+```bash
+clj-nrepl-eval -p <PORT> "(require '[my.namespace :as ns] :reload)"
+```
+
+**Test a function after requiring:**
+```bash
+clj-nrepl-eval -p <PORT> "(ns/my-function arg1 arg2)"
+```
+
+**Check if a file compiles:**
+```bash
+clj-nrepl-eval -p <PORT> "(require 'my.namespace :reload)"
+```
+
+**Multiple expressions:**
+```bash
+clj-nrepl-eval -p <PORT> "(def x 10) (* x 2) (+ x 5)"
+```
+
+**Complex multiline code (using heredoc):**
+```bash
+clj-nrepl-eval -p <PORT> <<'EOF'
+(def x 10)
+(* x 2)
+(+ x 5)
+EOF
+```
+*Note: Heredoc syntax may require permission approval.*
+
+**With custom timeout (in milliseconds):**
+```bash
+clj-nrepl-eval -p <PORT> --timeout 5000 "(long-running-fn)"
+```
+
+**Reset the session (clears all state):**
+```bash
+clj-nrepl-eval -p <PORT> --reset-session
+clj-nrepl-eval -p <PORT> --reset-session "(def x 1)"
+```
+
+## Available Options
+
+- `-p, --port PORT` - nREPL port (required)
+- `-H, --host HOST` - nREPL host (default: 127.0.0.1)
+- `-t, --timeout MILLISECONDS` - Timeout (default: 120000 = 2 minutes)
+- `-r, --reset-session` - Reset the persistent nREPL session
+- `-c, --connected-ports` - List previously connected nREPL sessions
+- `-d, --discover-ports` - Discover nREPL servers in current directory
+- `-h, --help` - Show help message
+
+## Important Notes
+
+- **Prefer command-line arguments:** Pass code as quoted strings: `clj-nrepl-eval -p <PORT> "(+ 1 2 3)"` - works with existing permissions
+- **Heredoc for complex code:** Use heredoc (`<<'EOF' ... EOF`) for truly multiline code, but note it may require permission approval
+- **Sessions persist:** State (vars, namespaces, loaded libraries) persists across invocations until the nREPL server restarts or `--reset-session` is used
+- **Automatic delimiter repair:** The tool automatically repairs missing or mismatched parentheses
+- **Always use :reload:** When requiring namespaces, use `:reload` to pick up recent changes
+- **Default timeout:** 2 minutes (120000ms) - increase for long-running operations
+- **Input precedence:** Command-line arguments take precedence over stdin
+
+## Typical Workflow
+
+1. Discover nREPL servers: `clj-nrepl-eval --discover-ports`
+2. Use **AskUserQuestion** tool to prompt user to select a port
+3. Require namespace:
+   ```bash
+   clj-nrepl-eval -p <PORT> "(require '[my.ns :as ns] :reload)"
+   ```
+4. Test function:
+   ```bash
+   clj-nrepl-eval -p <PORT> "(ns/my-fn ...)"
+   ```
+5. Iterate: Make changes, re-require with `:reload`, test again

+# Code-Reading-First → Generate Cypress Tests (Metabase)
+
+You are writing Cypress E2E tests for the **Metabase** codebase.
+Before generating ANY test code, you MUST analyze React component source code
+to understand DOM structure, selectors, and user flows.
+
+## Phase 0 — Research
+
+1. Read existing helpers before writing anything:
+   - `e2e/support/helpers/` — all shared helpers (restore, signInAs, openOrdersTable, etc.)
+   - `e2e/support/cypress_sample_database.ts` — table/field schema constants (ORDERS, PRODUCTS, etc.)
+   - `e2e/support/cypress_sample_instance_data.ts` — instance-specific IDs (ORDERS_DASHBOARD_ID, NORMAL_USER_ID, etc.)
+2. Glob `e2e/test/scenarios/` to find the closest existing spec to the area under test.
+   Study its patterns — match them exactly.
+3. Glob `frontend/src/metabase/` to find React components for the feature area.
+
+## Phase 1 — Code Analysis
+
+Read React component source to understand DOM structure. No browser needed — source code has everything.
+
+1. **Find relevant components**: Glob and grep `frontend/src/metabase/` for the feature area.
+2. **Extract selectors**: Grep for `data-testid` in relevant components.
+3. **Note visible text**: Read component JSX for button labels, headings, placeholders.
+4. **Note aria attributes**: Grep for `aria-label` in relevant components.
+5. **Understand user flows**: Read event handlers (onClick, onSubmit, onChange) to understand interactions.
+6. **Find API calls**: Grep for `Api.use`, `fetch`, `useQuery`, endpoint definitions to identify API calls to intercept.
+7. **Cross-reference with existing specs**: Find specs in the same area and reuse their proven selectors and `cy.intercept` patterns.
+
+## Phase 2 — Start Backend
+
+Use `MB_EDITION=oss` by default. Only use `MB_EDITION=ee` when the user explicitly asks to write an enterprise test.
+
+Start the backend using `run_in_background: true` (NOT `&`).
+`bin/e2e-backend` automatically detects if a backend is already running and reuses it.
+```bash
+MB_EDITION=oss bin/e2e-backend
+```
+
+Do NOT manually generate snapshots by running unrelated test specs.
+The `bun test-cypress` runner has `GENERATE_SNAPSHOTS: true` by default and automatically
+generates snapshots before running any spec. When running tests in Phase 4 via the `/e2e-test` skill,
+snapshots will be generated on the first run if they don't already exist.
+
+Restore clean test data:
+```bash
+curl -sf -X POST http://localhost:4000/api/testing/restore/default
+```
+
+## Phase 3 — Generate Cypress Spec
+
+### File location & naming
+
+Place specs in `e2e/test/scenarios/<area>/` mirroring the URL structure.
+Name: `<feature>.cy.spec.js` (NOT `.cy.spec.ts`).
+
+### Metabase conventions (mandatory)
+
+- **Helpers via `cy.H`**: All helpers are accessed via `const { H } = cy;` — NOT via direct imports from `e2e/support/helpers`.
+
+```js
+const { H } = cy;
+
+describe("feature name", () => {
+  beforeEach(() => {
+    H.restore();
+    cy.signInAsAdmin();
+  });
+});
+```
+
+- **Sample Database schema** (table/field definitions): Import from `cypress_sample_database`.
+
+```js
+import { ORDERS, ORDERS_ID, PRODUCTS } from "e2e/support/cypress_sample_database";
+```
+
+- **Instance data** (dashboard IDs, user IDs, etc.): Import from `cypress_sample_instance_data`.
+
+```js
+import { ORDERS_DASHBOARD_ID } from "e2e/support/cypress_sample_instance_data";
+```
+
+- **Selectors** (priority order):
+  1. `cy.findByText()` / `cy.findByLabelText()` / `cy.findByRole()` — from `@testing-library/cypress`
+  2. `cy.findByTestId()` — for `data-testid` attributes
+  3. `cy.get("[data-testid='...']")` — fallback
+  4. NEVER use positional selectors, CSS class names, or XPaths.
+
+- **Navigation helpers**: Use existing helpers like `H.openOrdersTable()`, `H.openNativeEditor()`,
+  `H.visitDashboard(id)`, `H.visitQuestion(id)` instead of raw `cy.visit()` chains.
+  Grep `e2e/support/helpers/` to discover what's available for your area.
+
+- **API setup over UI setup**: Use `cy.request()` or existing API helpers to set up state.
+  Only use the UI for the flow you're actually testing.
+
+- **Assertions**: Assert on visible text, URL, aria state — not DOM structure.
+
+- **Waits**: Never use `cy.wait(ms)`. Use `cy.intercept()` + `cy.wait("@alias")` for API calls,
+  or `cy.findByText().should("be.visible")` for DOM readiness.
+
+- **Isolation**: Each `it()` block must be independently runnable.
+  Don't depend on state from a previous `it()`.
+
+### Spec structure template
+
+```js
+const { H } = cy;
+import { ORDERS_DASHBOARD_ID } from "e2e/support/cypress_sample_instance_data";
+import { ORDERS, ORDERS_ID } from "e2e/support/cypress_sample_database";
+
+describe("area > sub-area > feature (#issue-number)", () => {
+  beforeEach(() => {
+    H.restore();
+    cy.signInAsAdmin();
+  });
+
+  it("should do the primary happy-path thing", () => {
+    // test
+  });
+
+  it("should handle the edge case", () => {
+    // test
+  });
+});
+```
+
+### Intercepts
+
+When you identified API calls during code analysis, stub or wait on them:
+
+```js
+cy.intercept("POST", "/api/dataset").as("dataset");
+// ... trigger action ...
+cy.wait("@dataset");
+```
+
+## Phase 4 — Validate
+
+After generating specs:
+1. Check that all imported helpers exist (Grep `e2e/support/helpers/`).
+2. **You MUST use the `/e2e-test` skill** to run tests — do NOT run `bun test-cypress` directly.
+   The `/e2e-test` skill handles edition selection, snapshot management, and correct env vars.
+   `/e2e-test GREP="should do the thing" --spec e2e/test/scenarios/<path>`
+   If you created multiple `it()` blocks, run each one individually to isolate failures.
+
+## Phase 5 — Fix Failures (up to 2 attempts)
+
+When a test fails, **try to fix it from Cypress output first**:
+1. Read the failure screenshot (path printed under `(Screenshots)`).
+2. Read the error message and code frame from the console output.
+3. Fix the test and re-run (back to Phase 4, step 2).
+
+If you cannot diagnose the issue after 2 attempts, proceed to Phase 6.
+
+## Phase 6 — Playwright Fallback
+
+Only reach this phase after 2 failed fix attempts from Phase 5. The backend is already running.
+
+Restore clean test data:
+```bash
+curl -sf -X POST http://localhost:4000/api/testing/restore/default
+```
+
+**Bypass CSP** headers before navigating (Metabase serves strict CSP that blocks dev server scripts).
+Use `browser_run_code` to set this up:
+
+```js
+async (page) => {
+  // Strip CSP headers so the page loads (mirrors Cypress chromeWebSecurity: false)
+  await page.context().route('**/*', async (route) => {
+    const response = await route.fetch();
+    const headers = { ...response.headers() };
+    delete headers['content-security-policy'];
+    delete headers['content-security-policy-report-only'];
+    await route.fulfill({ response, headers });
+  });
+
+  // Sign in via API
+  const response = await page.request.post('http://localhost:4000/api/session', {
+    data: { username: 'admin@metabase.test', password: '12341234' }
+  });
+  const session = await response.json();
+  await page.context().addCookies([{
+    name: 'metabase.DEVICE',
+    value: session.id,
+    domain: 'localhost',
+    path: '/'
+  }]);
+
+  await page.goto('http://localhost:4000');
+  await page.waitForLoadState('networkidle');
+  return 'signed in';
+}
+```
+
+**Maintain an observation log incrementally.** After EVERY significant Playwright interaction,
+IMMEDIATELY append what you observed to the scratch file BEFORE performing the next interaction:
+
+```bash
+cat >> /tmp/e2e-observations.md << 'OBSERVATION'
+## [Page/Flow name]
+- URL: /question/notebook#...
+- Clicked: "Box plot" button → visible text "Box plot", role: radio
+- Selectors: data-testid="viz-type-button", findByText("Box plot")
+- API call: POST /api/dataset (triggered on viz change)
+- Key state: after selecting viz type, summary sidebar shows metric picker
+OBSERVATION
+```
+
+For each page/flow:
+- Take an accessibility snapshot (`browser_snapshot`).
+- Click through interactive elements, fill forms, trigger modals.
+- **Append to the observation log immediately after each step**: URLs, visible text, aria labels, `data-testid` attrs, API calls.
+- Screenshot key states.
+
+After exploration:
+1. Read back your observation log: `cat /tmp/e2e-observations.md`
+2. Fix the test using observed selectors and behavior.
+3. Re-run the test (back to Phase 4).
+4. Clean up: `rm -f /tmp/e2e-observations.md`
+
+## Phase 7 — Cleanup
+
+After all tests pass (or after giving up on fixing failures), **always kill the backend on port 4000**:
+```bash
+lsof -ti:4000 | xargs kill 2>/dev/null || true
+```
+
+Do NOT use broad `pkill` patterns — there may be other Metabase instances on different ports.
+The backend process started in Phase 2 will NOT be killed automatically when the Claude session ends.
+Leaving it running wastes resources and can interfere with future sessions. Always clean up.
+
+## What NOT to do
+
+- Do NOT use Playwright as the first step — always analyze source code first.
+- Do NOT kill the backend between phases — it stays running throughout.
+- Do NOT invent selectors you didn't find in source code or observe in the browser.
+- Do NOT hardcode database IDs — import from `cypress_sample_database` or `cypress_sample_instance_data`.
+- Do NOT use `cy.wait(1000)` or any numeric wait.
+- Do NOT create setup flows through the UI when an API helper exists.
+- Do NOT put tests in `cypress/e2e/` — Metabase uses `e2e/test/scenarios/`.
+- Do NOT import helpers directly from `e2e/support/helpers` — use `const { H } = cy;`.

+
+## Edition selection
+
+**Default: `MB_EDITION=oss`** — runs without enterprise tokens, simpler and faster.
+
+Only use `MB_EDITION=ee` when the user explicitly asks to write or run an enterprise test.
+
+**For `MB_EDITION=ee`:**
+These tokens must be exported in the shell before starting Claude Code:
+- `CYPRESS_MB_ALL_FEATURES_TOKEN` — all features (most EE tests need this)
+- `CYPRESS_MB_PRO_SELF_HOSTED_TOKEN` — pro self-hosted (permissions, SSO, sandboxing)
+- `CYPRESS_MB_STARTER_CLOUD_TOKEN` — starter plan (rarely needed)
+- `CYPRESS_MB_PRO_CLOUD_TOKEN` — pro cloud (rarely needed)
+
+**NEVER echo, print, or log token values. Only check if they are set:**

+```
+
+If tokens are missing, tell the user: "EE tokens are not set. Either export them and restart Claude Code, or add `MB_EDITION=oss` to run OSS-only tests."
+
+## Running
+
+First check if snapshots exist:
+```bash
+ls e2e/snapshots/default.sql 2>/dev/null && echo "snapshots exist" || echo "snapshots missing"
+```
+
+If snapshots exist, skip regeneration for speed:

+
+If snapshots are missing (first run), let the runner generate them:
+```bash
+MB_EDITION=oss CYPRESS_VIDEO=false CYPRESS_RETRIES=0 CYPRESS_GUI=false bun test-cypress $ARGUMENTS
+```
+
+When running enterprise tests, replace `MB_EDITION=oss` with `MB_EDITION=ee` in the commands above.
+
+If `$ARGUMENTS` is empty, ask the user which spec to run.
+
+If the user provides a test name or fuzzy name instead of a spec path, find the spec file:
+```bash
+find e2e/test/scenarios -name "*FUZZY_NAME*.cy.spec.*" -type f
+```
+Then run with `--spec "path/to/matched.cy.spec.js"`.
+
+To filter by test name, use the `GREP` env var (not `--env grep=`, which breaks on commas):
+```bash
+GREP="test name here" MB_EDITION=oss bun test-cypress --spec path/to/spec.js
+```
+
+## Stress test (flaky detection)
+
+When the user asks to verify a test is not flaky:
+
+```bash
+MB_EDITION=oss bin/e2e-stress-test $ARGUMENTS
+```
+
+Set `E2E_STRESS_RUNS=N` for more iterations (default: 5). Stops on first failure and prints screenshot paths. Read those screenshots to analyze the failure.
+
+## Analyzing failures
+
+When tests fail:
+
+1. Read the **screenshot** for each failure — paths are printed in Cypress output under `(Screenshots)`, typically at `cypress/screenshots/<spec-name>/<test-name> (failed).png`
+2. Read the error message and code frame from the console output
+3. Identify the root cause: is it a test bug, a product bug, or a timing issue?
+4. Suggest a fix with specific code changes

+
+# Emotion → Mantine + CSS Modules Migration Skill
+
+Migrate Emotion styled-components (`@emotion/styled`, `@emotion/react`) to Mantine layout components with style props and CSS modules. The goal is zero Emotion imports, zero inline styles, and maximum use of design system tokens.
+
+## Priority Order (Strict)
+
+1. **Mantine components + style props** — `Box`, `Flex`, `Stack`, `Group`, `Text`, `Title`, `Card`. This is the DEFAULT. Every CSS property must be checked against style props FIRST.
+2. **CSS modules** (`.module.css`) — ONLY for properties that Mantine style props genuinely cannot express: pseudo-selectors (`:hover`, `:focus`, `::before`), `box-shadow`, `border` shorthand, `animation`/`@keyframes`, complex selectors, `cursor`, `pointer-events`, `overflow`, `text-overflow`, `white-space`, `transition`.
+3. **Inline styles ONLY for dynamic values** — `style={{ }}` is allowed only for truly dynamic runtime values (e.g., computed widths, positions, data-driven colors). All static styles must use Mantine props or CSS modules.
+
+### Mantine-First Decision Gate (CRITICAL)
+
+For EACH styled component, go through every CSS property and ask: "Can this be a Mantine style prop?" If yes → style prop. If no → CSS module. Do NOT dump an entire component into a CSS module just because one property needs it — split them.
+
+**Properties that ARE style props** (use these, not CSS modules):
+
+- `display` → `display` prop
+- `color` → `c` prop (`c="brand"`, `c="text-primary"`)
+- `background-color` → `bg` prop (`bg="background-primary"`)
+- `font-size` → `fz` prop (`fz="md"`)
+- `font-weight` → `fw` prop (`fw="bold"`)
+- `line-height` → `lh` prop (`lh="md"`)
+- `text-align` → `ta` prop (`ta="center"`)
+- `padding` (all variants) → `p`, `px`, `py`, `pt`, `pb`, `pl`, `pr`
+- `margin` (all variants) → `m`, `mx`, `my`, `mt`, `mb`, `ml`, `mr`
+- `width` → `w`, `min-width` → `miw`, `max-width` → `maw`
+- `height` → `h`, `min-height` → `mih`, `max-height` → `mah`
+- `flex` → `flex` prop (`flex="0 0 auto"`, `flex={1}`)
+- `gap` → `gap` prop (on Flex/Stack/Group)
+- `align-items` → `align` prop (on Flex/Stack/Group)
+- `justify-content` → `justify` prop (on Flex/Stack/Group)
+- `flex-direction` → `direction` prop (on Flex)
+- `flex-wrap` → `wrap` prop (on Flex)
+- `position` → `pos` prop
+- `top/right/bottom/left` → `top`, `right`, `bottom`, `left` props
+- `opacity` → `opacity` prop
+
+**Properties that NEED CSS modules** (no style prop equivalent):
+
+- `:hover`, `:focus`, `:active`, `::before`, `::after` (pseudo-selectors)
+- `box-shadow`, `border` (shorthand with color), `outline`
+- `cursor`, `pointer-events`
+- `overflow`, `text-overflow`, `white-space`
+- `animation`, `transition`, `transform`
+- `@media` queries (UNLESS it's simple responsive spacing/sizing — then use responsive syntax: `p={{ base: "md", lg: "xl" }}`)
+
+**Hybrid approach** — when a component needs BOTH, put style props on the Mantine component AND add a CSS module class for the rest:
+
+```tsx
+<Flex
+  className={S.root}       /* for :hover, box-shadow, border */
+  align="center"            /* style prop */
+  gap="sm"                  /* style prop */
+  p="md"                    /* style prop */
+  bg="background-primary"   /* style prop */
+>
+```
+
+## CSS Module Conventions (Strict)
+
+### Class Naming: camelCase
+
+All CSS module class names MUST use **camelCase**. This is the dominant convention across the codebase (~830 camelCase vs ~620 PascalCase classes), used consistently in Mantine UI components, and matches standard CSS module conventions.
+
+```css
+/* CORRECT */
+.root {
+}
+.settingsSection {
+}
+.dragHandle {
+}
+.closeIcon {
+}
+
+/* WRONG — do not use PascalCase or kebab-case */
+.ItemRoot {
+}
+.settings-section {
+}
+```
+
+Modifier/state classes also use camelCase:
+
+```css
+.selected {
+}
+.disabled {
+}
+.interactive {
+}
+.draggable {
+}
+```
+
+### No Cascading — Direct Class Assignment
+
+Cascading selectors are **discouraged**. Instead of styling through parent-child relationships, assign a class directly to the element that needs styling.
+
+```css
+/* WRONG — cascading/descendant selectors */
+.root > input {
+}
+.root .label {
+}
+.container > div > span {
+}
+
+/* CORRECT — direct class on the target element */
+.input {
+}
+.label {
+}
+.title {
+}
+```
+
+The only acceptable nesting patterns are:
+
+- **Pseudo-selectors on the same element**: `.item { &:hover { } }`
+- **Modifier composition**: `.item { &.selected { } }`
+- **Hover-reveal patterns** where a parent hover affects a child: `.root:hover .showOnHover { opacity: 1; }` — but only when structurally necessary (the child has no way to know about the parent's hover state)
+
+### Import Alias
+
+Always import the CSS module as `S`:
+
+```tsx
+import S from "./ComponentName.module.css";
+```
+
+## Step-by-Step Migration Process
+
+### Step 1: Read and Understand
+
+Read the `.styled.tsx` file AND every component that imports from it. Understand:
+
+- Which styled components are used and where
+- Which props drive dynamic styles
+- Which styles are static vs conditional
+- Which styles can map directly to Mantine style props
+
+### Step 2: Classify Each Styled Component
+
+For each styled component, apply the Mantine-First Decision Gate above. Then determine the migration target:
+
+| Emotion Pattern                                              | Migration Target                                                                                                                                                           |
+| ------------------------------------------------------------ | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| `styled.div` with only layout/spacing/color                  | `Box`, `Flex`, `Stack`, or `Group` with style props. **NO CSS module needed.**                                                                                             |
+| `styled.div` with flexbox column                             | `Stack` component with style props                                                                                                                                         |
+| `styled.div` with flexbox row                                | `Flex` or `Group` component with style props                                                                                                                               |
+| `styled.span` / `styled.p` with color/weight/size            | **`Text component="span"` with style props** (`c`, `fw`, `fz`). NO CSS module.                                                                                             |
+| `styled.div` with hover/focus/pseudo-selectors               | **Hybrid**: Mantine component with style props for expressible properties + CSS module class for pseudo-selectors only                                                     |
+| `styled.div` with media queries (simple spacing/sizing)      | **Responsive style props**: `p={{ base: "md", lg: "xl" }}`. NO CSS module.                                                                                                 |
+| `styled.div` with media queries (complex/non-spacing)        | CSS module for the media query parts, style props for the rest                                                                                                             |
+| `styled.div` with animations/keyframes                       | CSS module for animation, style props for layout                                                                                                                           |
+| `styled(SomeComponent)` with only color/spacing/flex         | **Wrap in Mantine component** with style props: `<Box c="brand" flex="0 0 auto"><Icon /></Box>`, or pass style props if the component accepts them                         |
+| `styled(SomeComponent)` with pseudo-selectors/complex styles | CSS module `className` on the component                                                                                                                                    |
+| Dynamic props `styled.div<{ isActive: boolean }>`            | Mantine style props for simple toggles (`c={active ? "brand" : "text-primary"}`), `cx()` with CSS module classes for complex state combinations involving pseudo-selectors |
+
+### Step 3: Create CSS Module (if needed)
+
+Create `ComponentName.module.css` alongside the component file:
+
+```css
+/* Use design system tokens — NEVER raw color/spacing values */
+.root {
+  border: 1px solid var(--mb-color-border);
+  border-radius: var(--mantine-radius-md);
+  background-color: var(--mb-color-background-primary);

+.active {
+  background-color: var(--mb-color-brand);
+  color: var(--mb-color-text-primary-inverse);
+}
+
+.disabled {
+  color: var(--mb-color-text-tertiary);
+  pointer-events: none;
+}
+
+/* Hover/focus/pseudo-selectors — nest with & */
+.interactive {
+  cursor: pointer;
+
+  &:hover {
+    color: var(--mb-color-brand);
+    background-color: var(--mb-color-background-hover);

+.root:hover .showOnHover {
+  opacity: 1;
+}
+
+/* Responsive styles */
+@media (--breakpoint-min-md) {
+  .root {
+    padding: var(--mantine-spacing-lg);
+  }
+}
+```
+
+### Step 4: Update the Component TSX
+
+```tsx
+import cx from "classnames";
+import CS from "metabase/css/core/index.css";
+import { Box, Flex, Group, Stack, Text } from "metabase/ui";
+import S from "./ComponentName.module.css";
+
+// Dynamic props → cx() with conditional classes
+<Flex
+  className={cx(S.root, {
+    [S.active]: isActive,
+    [S.disabled]: disabled,
+  })}
+  align="center"
+  gap="sm"
+  p="md"
+  w="100%"
+>
+```
+
+### Step 5: Delete the `.styled.tsx` File
+
+Remove the old styled file entirely. Remove all imports of it from other files.
+
+### Step 6: Verify
+
+- Confirm zero `@emotion/styled` or `@emotion/react` imports remain in the migrated files
+- Confirm no static inline styles (dynamic runtime values are fine)
+- Confirm all colors use tokens, not raw hex/rgb values
+
+## Design System Token Reference
+
+### Mantine Style Props (use directly on components)

+- Also available: `--breakpoint-max-*` variants
+
+### Snap Hardcoded Literals to Nearest Design Token (CRITICAL)
+
+When migrating, **never carry over hardcoded `rem`/`px` values** from the original Emotion code. Instead, snap them to the nearest design system token. The original values were often arbitrary — the migration is an opportunity to align with the design system.
+
+**Spacing** — snap to the nearest Mantine spacing token:
+
+| Hardcoded value                   | Nearest token | Style prop   | CSS variable                   |
+| --------------------------------- | ------------- | ------------ | ------------------------------ |
+| `0.125rem` (2px)                  | `2px`         | `2` (number) | `2px` (keep literal, no token) |
+| `0.2rem` (3.2px), `0.25rem` (4px) | **xs** (4px)  | `"xs"`       | `var(--mantine-spacing-xs)`    |
+| `0.5rem` (8px)                    | **sm** (8px)  | `"sm"`       | `var(--mantine-spacing-sm)`    |
+| `0.75rem` (12px)                  | between sm/md | `rem(12)`    | `0.75rem` (no exact token)     |
+| `1rem` (16px)                     | **md** (16px) | `"md"`       | `var(--mantine-spacing-md)`    |
+| `1.5rem` (24px)                   | **lg** (24px) | `"lg"`       | `var(--mantine-spacing-lg)`    |
+| `2rem` (32px)                     | **xl** (32px) | `"xl"`       | `var(--mantine-spacing-xl)`    |
+
+**Border radius** — snap to the nearest Mantine radius token:
+
+| Hardcoded value  | Nearest token                 | CSS variable               |
+| ---------------- | ----------------------------- | -------------------------- |
+| `0.25rem` (4px)  | **xs** (4px)                  | `var(--mantine-radius-xs)` |
+| `0.375rem` (6px) | **sm** (6px)                  | `var(--mantine-radius-sm)` |
+| `0.5rem` (8px)   | **md** (8px)                  | `var(--mantine-radius-md)` |
+| `1rem`+ (16px+)  | **xl** (40px) or keep literal | `var(--mantine-radius-xl)` |
+
+**Font sizes** — snap to the nearest Mantine font size token:
+
+| Hardcoded value                  | Nearest token | Style prop | CSS variable                  |
+| -------------------------------- | ------------- | ---------- | ----------------------------- |
+| `0.6875rem` (11px)               | **xs** (11px) | `fz="xs"`  | `var(--mantine-font-size-xs)` |
+| `0.75rem` (12px)                 | **sm** (12px) | `fz="sm"`  | `var(--mantine-font-size-sm)` |
+| `0.875rem` (14px), `1rem` (16px) | **md** (14px) | `fz="md"`  | `var(--mantine-font-size-md)` |
+| `1.063rem` (17px)                | **lg** (17px) | `fz="lg"`  | `var(--mantine-font-size-lg)` |
+| `1.3rem` (21px)                  | **xl** (21px) | `fz="xl"`  | `var(--mantine-font-size-xl)` |
+
+**Rules:**
+
+- If the hardcoded value is within ~2px of a token, use the token
+- If it falls exactly between two tokens, prefer the smaller one (tighter is safer)
+- If no token is close (e.g., `48px` spacing), use `rem(48)` for style props or the literal value in CSS modules
+- This applies everywhere: style props, CSS module values, Icon `size` props, etc.
+
+## Common Migration Patterns
+
+### Pattern 1: Static Layout Container → Mantine Component
+
+**Before:**
+
+```tsx
+// Component.styled.tsx
+export const Container = styled.div`
+  display: flex;
+  align-items: center;
+  gap: 0.5rem;
+  padding: 1rem;
+  width: 100%;
+`;
+```
+
+**After:**
+
+```tsx
+<Flex align="center" gap="sm" p="md" w="100%">
+```
+
+### Pattern 2: Vertical Stack → Stack Component
+
+**Before:**
+
+```tsx
+export const Wrapper = styled.div`
+  display: flex;
+  flex-direction: column;
+  gap: 1.5rem;
+  padding: 2rem;
+`;
+```
+
+**After:**
+
+```tsx
+<Stack gap="lg" p="xl">
+```
+
+### Pattern 3: Dynamic Props → cx() with CSS Module Classes
+
+**Before:**
+
+```tsx
+export const Item = styled.div<{ isSelected: boolean; disabled: boolean }>`
+  color: ${(props) =>
+    props.disabled ? color("text-tertiary") : color("text-primary")};
+  background-color: ${(props) =>
+    props.isSelected ? color("brand") : "transparent"};
+  cursor: ${(props) => (props.disabled ? "default" : "pointer")};
+
+  &:hover {
+    color: ${(props) => !props.disabled && color("brand")};
+  }
+`;
+```
+
+**After (CSS module):**
+
+```css
+/* Item.module.css */
+.itemRoot {
+  color: var(--mb-color-text-primary);
+  cursor: pointer;
+
+  &:hover {
+    color: var(--mb-color-brand);
+  }
+}
+
+.selected {
+  background-color: var(--mb-color-brand);
+}
+
+.disabled {
+  color: var(--mb-color-text-tertiary);
+  cursor: default;
+
+  &:hover {
+    color: var(--mb-color-text-tertiary);
+  }
+}
+```
+
+**After (TSX):**
+
+```tsx
+<Box
+  className={cx(S.itemRoot, {
+    [S.selected]: isSelected,
+    [S.disabled]: disabled,
+  })}
+>
+```
+
+### Pattern 4: Extending a Component → Style Props First, CSS Module Only If Needed
+
+When a styled component wraps another component, first check if the styles can be expressed as style props on a Mantine wrapper or on the component itself. Only use a CSS module when properties genuinely need it.
+
+**Before:**
+
+```tsx
+export const CardIcon = styled(Icon)`
+  display: block;
+  flex: 0 0 auto;
+  color: var(--mb-color-brand);
+`;
+
+export const CardTitle = styled(Ellipsified)`
+  color: var(--mb-color-text-primary);
+  font-size: 1rem;
+  font-weight: bold;
+  margin-left: 1rem;
+`;
+```
+
+**After — style props on Mantine wrapper (preferred when ALL properties are expressible):**
+
+```tsx
+<Box display="block" flex="0 0 auto" c="brand">
+  <Icon {...icon} />
+</Box>
+<Box c="text-primary" fz="md" fw="bold" ml="md">
+  <Ellipsified>{title}</Ellipsified>
+</Box>
+```
+
+**After — CSS module (use only when component has pseudo-selectors or non-expressible styles):**
+
+```css
+.icon {
+  color: var(--mb-color-brand);
+  width: 1.5rem;
+  height: 1.5rem;
+  cursor: pointer;
+
+  &:hover {
+    color: var(--mb-color-brand-hover);
+  }
+}
+```
+
+```tsx
+<Icon className={S.icon} name="warning" />
+```
+
+### Pattern 4b: `styled.span` / `styled.p` with Text Styles → `Text` Component
+
+**Before:**
+
+```tsx
+export const Label = styled.span`
+  color: var(--mb-color-text-secondary);
+  font-weight: bold;
+`;
+
+export const Title = styled.span`
+  color: var(--mb-color-text-primary);
+  font-size: 1rem;
+  font-weight: bold;
+  margin-left: 0.5rem;
+`;
+```
+
+**After — `Text` component with style props (NO CSS module needed):**
+
+```tsx
+<Text component="span" c="text-secondary" fw="bold">
+  {label}
+</Text>
+
+<Text component="span" c="text-primary" fz="md" fw="bold" ml="sm">
+  {title}
+</Text>
+```
+
+`Text` renders as `<p>` by default. Use `component="span"` to render inline. All color, typography, and spacing props work directly — no CSS module needed for pure text styling.
+
+### Pattern 5: Keyframes Animation → CSS Module
+
+**Before:**
+
+```tsx
+const spin = keyframes`
+  from { transform: rotate(0deg); }
+  to { transform: rotate(360deg); }
+`;
+
+export const Spinner = styled.div`
+  animation: ${spin} 1s infinite linear;
+`;
+```
+
+**After (CSS module):**
+
+```css
+@keyframes spin {
+  from {
+    transform: rotate(0deg);
+  }
+  to {
+    transform: rotate(360deg);
+  }
+}
+
+.spinner {
+  animation: spin 1s infinite linear;
+}
+```
+
+**After (TSX):**
+
+```tsx
+<Box className={S.spinner} />
+```
+
+### Pattern 6: color() Function → CSS Variables
+
+| Emotion (JS)            | CSS Module                                                   | Mantine Style Prop          |
+| ----------------------- | ------------------------------------------------------------ | --------------------------- |
+| `color("brand")`        | `var(--mb-color-brand)`                                      | `c="brand"` or `bg="brand"` |
+| `color("text-primary")` | `var(--mb-color-text-primary)`                               | `c="text-primary"`          |
+| `color("border")`       | `var(--mb-color-border)`                                     | N/A (use CSS module)        |
+| `alpha("brand", 0.2)`   | `color-mix(in srgb, var(--mb-color-brand), transparent 80%)` | N/A (use CSS module)        |
+
+### Pattern 7: Responsive Spacing/Sizing → Responsive Style Props (NOT CSS Media Queries)
+
+When a styled component only changes spacing, sizing, or other style-prop-expressible values at breakpoints, use Mantine's responsive syntax instead of CSS module media queries.
+
+**Before:**
+
+```tsx
+export const CaptionRoot = styled.div`
+  margin-bottom: 1.5rem;
+
+  ${breakpointMinExtraLarge} {
+    margin-bottom: 2rem;
+  }
+`;
+```
+
+**After — responsive style prop (NO CSS module needed):**
+
+```tsx
+<Flex mb={{ base: "lg", xl: "xl" }}>
+```
+
+Breakpoint keys: `base` (default), `xs` (40em), `sm` (48em), `md` (60em), `lg` (80em), `xl` (120em).
+
+Only use CSS module `@media` queries when the responsive change involves non-style-prop properties (e.g., `box-shadow`, `border`, `cursor` changes at breakpoints).
+
+### Pattern 8: Dynamic Computed Styles → Inline Styles
+
+Inline styles are allowed **only** for truly dynamic values computed at runtime (e.g., widths, positions, colors from data). Everything else must use Mantine style props or CSS modules.
+
+**Before:**
+
+```tsx
+export const Bar = styled.div<{ width: number }>`
+  width: ${(props) => props.width}%;
+`;
+```
+
+**After:**
+
+```tsx
+<Box style={{ width: `${width}%` }} />
+```
+
+### Pattern 9: Core CSS Utility Classes (Discouraged)
+
+**Do NOT introduce new `CS` utility class usage.** Core CSS utilities (`CS` from `metabase/css/core/index.css`) are legacy and discouraged for new code. Prefer Mantine style props or CSS modules instead.
+
+If existing code already uses `CS` classes and you're not migrating that specific code, leave them alone. But when migrating Emotion → Mantine, replace with the proper alternative:
+
+| Instead of `CS.*`   | Use                                                     |
+| ------------------- | ------------------------------------------------------- |
+| `CS.overflowHidden` | CSS module: `overflow: hidden`                          |
+| `CS.cursorPointer`  | CSS module: `cursor: pointer`                           |
+| `CS.flex1`          | Style prop: `flex={1}`                                  |
+| `CS.flexNoShrink`   | Style prop: `flex="0 0 auto"`                           |
+| `CS.textBrandHover` | CSS module: `&:hover { color: var(--mb-color-brand); }` |
+
+### Pattern 10: Shared Emotion Styles Across Files → Shared CSS Module + cx()
+
+When Emotion exports a shared `css` block (like `animationStyles`) imported by many files, create ONE CSS module with the shared keyframe and a reusable class, then compose via `cx()`.
+
+**Before (Emotion — shared animation used by 13+ skeleton files):**
+
+```tsx
+// ChartSkeleton.styled.tsx — defines shared animation
+const fadingKeyframes = keyframes`
+  0% { opacity: 0.0625; }
+  50% { opacity: 0.125; }
+  100% { opacity: 0.0625; }
+`;
+export const animationStyles = css`
+  opacity: 0.1;
+  animation: ${fadingKeyframes} 1.5s infinite;
+`;
+
+// AreaSkeleton.styled.tsx — consumes it
+import { animationStyles } from ".../ChartSkeleton.styled";
+export const SkeletonImage = styled.svg`
+  ${animationStyles};
+  flex: 1 1 0;
+  margin-top: 1rem;
+  border-bottom: 1px solid currentColor;
+`;
+
+// BarSkeleton.styled.tsx — also consumes it
+import { animationStyles } from ".../ChartSkeleton.styled";
+export const SkeletonImage = styled.svg`
+  ${animationStyles};
+  flex: 1 1 0;
+  margin-top: 1rem;
+`;
+```
+
+**After — shared CSS module:**
+
+```css
+/* ChartSkeleton.module.css */
+@keyframes fading {
+  0% {
+    opacity: 0.0625;
+  }
+
+  50% {
+    opacity: 0.125;
+  }
+
+  100% {
+    opacity: 0.0625;
+  }
+}
+
+.animated {
+  opacity: 0.1;
+  animation: fading 1.5s infinite;
+}
+```
+
+**After — per-component CSS modules with own styles only:**
+
+```css
+/* AreaSkeleton.module.css */
+.skeletonImage {
+  flex: 1 1 0;
+  margin-top: 1rem;
+  border-bottom: 1px solid currentColor;
+}
+```
+
+```css
+/* BarSkeleton.module.css */
+.skeletonImage {
+  flex: 1 1 0;
+  margin-top: 1rem;
+}
+```
+
+**After — component TSX uses cx() to compose:**
+
+```tsx
+// AreaSkeleton.tsx
+import cx from "classnames";
+import ChartSkeletonS from "../ChartSkeleton/ChartSkeleton.module.css";
+import S from "./AreaSkeleton.module.css";
+
+const AreaSkeleton = (): JSX.Element => {
+  return (
+    <svg
+      className={cx(ChartSkeletonS.animated, S.skeletonImage)}
+      xmlns="http://www.w3.org/2000/svg"
+      viewBox="0 0 371 113"
+      preserveAspectRatio="none"
+    >
+      <path d="..." fill="currentColor" />
+    </svg>
+  );
+};
+```
+
+The shared module owns the `@keyframes` and the `.animated` class. Each consumer composes it with its own module class via `cx()`. No duplication of the keyframe definition.
+
+## Import Template
+
+```tsx
+import cx from "classnames"; // only if needed for conditional classes
+
+import { Box, Flex, Group, Stack, Text, rem } from "metabase/ui";
+
+import S from "./ComponentName.module.css"; // only if CSS module is needed
+```
+
+## Checklist Before Finishing
+
+- [ ] **MANTINE-FIRST CHECK**: Every CSS property that has a style prop equivalent (`c`, `bg`, `p`, `m`, `fw`, `fz`, `flex`, `gap`, `align`, `w`, `h`, etc.) is expressed as a style prop, NOT in a CSS module
+- [ ] `styled.span`/`styled.p` with only color/weight/size are replaced with `Text component="span"` + style props, NOT CSS module classes
+- [ ] `styled.div` with only layout props are replaced with `Flex`/`Stack`/`Group`/`Box` + style props, NOT CSS module classes
+- [ ] Responsive spacing/sizing uses responsive style props (`mb={{ base: "lg", xl: "xl" }}`), NOT CSS module `@media` queries
+- [ ] CSS modules are used ONLY for: pseudo-selectors, box-shadow, border, cursor, overflow, animation, transition, transform, or complex selectors
+- [ ] All `@emotion/styled` and `@emotion/react` imports removed from migrated files
+- [ ] The `.styled.tsx` file is deleted
+- [ ] All imports of the deleted styled file are updated
+- [ ] No static inline styles — `style={{ }}` used only for truly dynamic runtime values
+- [ ] All colors use design tokens (`c="brand"`, `var(--mb-color-brand)`), not raw hex/rgb
+- [ ] All spacing uses design tokens (`p="md"`, `var(--mantine-spacing-md)`), not arbitrary px values — hardcoded `rem`/`px` literals snapped to the nearest token (see mapping table above)
+- [ ] All border-radius values use radius tokens (`var(--mantine-radius-md)`), not hardcoded `0.5rem`
+- [ ] All font sizes use font-size tokens (`fz="md"`, `var(--mantine-font-size-md)`), not hardcoded `1rem`
+- [ ] Layout uses Mantine components (`Flex`, `Stack`, `Group`, `Box`, `Text`) not raw divs/spans with CSS
+- [ ] All CSS module class names use camelCase
+- [ ] No cascading/descendant selectors targeting raw elements — use direct class assignment instead
+- [ ] Component renders identically to the original (visually verify if possible)
+
+## Visual Verification with Screenshots (Optional — Only When Explicitly Asked)
+
+When the user explicitly asks to create before/after screenshots, use the Playwright MCP tools to capture them. This is NOT done by default — only when requested.
+
+Screenshots must be taken in **both light and dark mode** to verify token usage is correct in both themes.

+Toggle between light and dark mode using the Metabase settings API. Use Playwright's `browser_evaluate` or `browser_navigate` with fetch:
+
+```js
+// Switch to dark mode
+await fetch("/api/setting/color-scheme", {
+  method: "PUT",
+  headers: { "Content-Type": "application/json" },
+  body: JSON.stringify({ value: "dark" }),
+});
+
+// Switch to light mode
+await fetch("/api/setting/color-scheme", {
+  method: "PUT",
+  headers: { "Content-Type": "application/json" },
+  body: JSON.stringify({ value: "light" }),
+});
+```
+
+After switching, reload the page for the theme to take effect.
+
+### Process
+
+For each state (**after** = migrated code, **before** = stashed original), capture screenshots in both themes at both viewport widths. This produces **8 screenshots total**.
+
+1. **Take "after" screenshots first** (migrated code is already in place):
+
+   - Navigate to the page that renders the migrated components (`browser_navigate`)
+   - Wait for content to load (`browser_wait_for` with key text, or `textGone: "Loading..."`)
+   - Close the sidebar if it overlaps content on narrow viewports (`browser_click` the toggle button)
+   - **Light mode** (set `color-scheme` to `"light"` via API, reload):
+     - Desktop (1280x900): `after-light-desktop.png`
+     - Narrow (640x900), close sidebar: `after-light-narrow.png`
+   - **Dark mode** (set `color-scheme` to `"dark"` via API, reload):
+     - Desktop (1280x900): `after-dark-desktop.png`
+     - Narrow (640x900), close sidebar: `after-dark-narrow.png`
+
+2. **Stash changes to capture "before" screenshots**:
+
+   - Run `git stash --include-untracked` to temporarily revert to the Emotion version
+   - Repeat the same 4 screenshots with `before-` prefix:
+     - `before-light-desktop.png`, `before-light-narrow.png`
+     - `before-dark-desktop.png`, `before-dark-narrow.png`
+   - Run `git stash pop` to restore the migrated code
+
+3. **Restore the user's original color scheme** (set back to `"auto"` or whatever it was before).
+
+4. **Display all 8 screenshots** using the `Read` tool so the user can visually compare before/after in both themes at both viewport sizes.
+
+### Key Details
+
+- Save screenshots in the repo root (they will be untracked — user can delete after review)
+- The dev server must be running (typically `http://localhost:3000`)
+- Use `browser_snapshot` to find element refs when you need to click buttons (e.g., sidebar toggle)
+- The greeting text on the home page changes randomly on each load — this is expected, not a regression
+- If the page being tested is not the home page, navigate to the correct URL that exercises the migrated components
+- Dark mode screenshots are critical for verifying that CSS variable tokens (`var(--mb-color-*)`) are used correctly — hardcoded colors will look wrong in dark mode

+description: Export content from a running Metabase instance, validate with checkers, edit YAML, and import back. Use when the user wants to export, import, or run the full serdes round-trip workflow.
+---
+
+# Serdes Workflow Skill
+
+End-to-end workflow for exporting Metabase content as YAML, validating it, editing it, and importing it back.
+
+## Prerequisites
+
+All commands require the `:ee` alias since export, import, and checkers live in enterprise code.
+
+You need `MB_DB_CONNECTION_URI` set to point at the target Metabase Postgres database when importing. The running dev instance's connection string is in the worktree environment (check the nREPL or startup output).
+
+## Export
+
+```bash
+clojure -M:run:ee export /path/to/export-dir
+```
+
+Flags:
+- `-c 123,456` - export only specific collection IDs
+- `-f` - include field values
+- `-e` - continue on error
+
+This writes YAML files in the serdes directory layout:
+```
+databases/<db-name>/<db-name>.yaml
+databases/<db-name>/schemas/<schema>/tables/<table>/<table>.yaml
+databases/<db-name>/schemas/<schema>/tables/<table>/fields/<field>.yaml
+collections/<eid>_<slug>/cards/<eid>_<slug>.yaml
+```
+
+## Validate
+
+Always run both checkers after any modification. They skip full Metabase startup (~8s each).
+
+### Structural checker (fast, schema-based)
+```bash
+clojure -M:run:ee --mode checker --checker structural --export /path/to/export-dir
+```
+Validates YAML shapes against Malli schemas. Catches typos, missing required fields, wrong types.
+
+### Cards checker (query validation)
+```bash
+clojure -M:run:ee --mode checker --checker cards --export /path/to/export-dir
+```
+Validates that card queries resolve correctly against exported metadata (tables, fields, FKs). Uses MLv2 under the hood.
+
+Additional cards checker flags:
+- `--lenient` - fabricate metadata on demand (when no database schema files exist)
+- `--manifest /path/to/manifest.yaml` - write manifest of all referenced entities (lenient mode only)
+- `--output /path/to/results.edn` - write detailed results to file
+
+## Edit YAML
+
+See the **serdes-yaml-edit** skill for guidance on editing YAML files. The critical rule: **run both checkers after every edit before proceeding**.
+
+## Import
+
+```bash
+MB_DB_CONNECTION_URI="postgres://user:pass@localhost:5432/metabase_dbname" \
+  clojure -M:run:ee import /path/to/export-dir -e
+```
+
+The `-e` flag continues on error. The `MB_DB_CONNECTION_URI` must point at the same Postgres database the running Metabase instance uses - without it, import defaults to H2 which is wrong.
+
+## Full Demo Sequence
+
+1. Export: `clojure -M:run:ee export /tmp/metabase-export`
+2. Validate baseline: run both checkers
+3. Edit YAML files (see serdes-yaml-edit skill)
+4. Re-validate: run both checkers again
+5. Import: `MB_DB_CONNECTION_URI=... clojure -M:run:ee import /tmp/metabase-export -e`
+6. Verify in browser

+description: Edit Metabase serdes YAML files (cards, dashboards, databases) with correct portable references and structural conventions. Use when modifying exported YAML content.
+---
+
+# Serdes YAML Edit Skill
+
+## Golden Rule
+
+**Run both checkers after every edit.** No exceptions. Do not batch multiple edits before validating.
+
+```bash
+clojure -M:run:ee --mode checker --checker structural --export /path/to/export-dir
+clojure -M:run:ee --mode checker --checker cards --export /path/to/export-dir
+```
+
+If either checker fails, fix the issue before making further edits.
+
+## Portable References
+
+Serdes YAML uses portable references instead of integer IDs. This is the most important concept for editing.
+
+### Database references
+String name: `"Sample Database"`
+
+### Table references
+Array of `[database, schema, table]`:
+```yaml
+table_id:
+- Sample Database
+- PUBLIC
+- ACCOUNTS
+```
+
+### Field references
+Array of `[database, schema, table, field]`:
+```yaml
+id:
+- Sample Database
+- PUBLIC
+- ACCOUNTS
+- EMAIL
+```
+
+### Field refs in queries
+```yaml
+field_ref:
+- field
+- - Sample Database
+  - PUBLIC
+  - ACCOUNTS
+  - EMAIL
+- null
+```
+The outer array is `[field, <field-path>, <options>]`. The options are usually `null`.
+
+### Card references
+Entity ID string (21 characters): `"Qk5TgsNx4ubXIUtsQmT8G"`
+
+### Source table in queries
+```yaml
+dataset_query:
+  database: Sample Database
+  query:
+    source-table:
+    - Sample Database
+    - PUBLIC
+    - ACCOUNTS
+  type: query
+```
+
+## Safe Edits (low risk)
+
+These rarely break validation:
+- `name` - card/dashboard display name
+- `description` - card/dashboard description
+- `display` - visualization type (table, bar, line, pie, etc.)
+- `visualization_settings` - chart configuration
+- `archived` - true/false
+- `collection_id` - move to a different collection (use entity_id of target collection, or null for root)
+
+## Structural Edits (must match schema)
+
+These must use valid portable refs and will be caught by the cards checker if wrong:
+- `dataset_query` - the query definition
+- `result_metadata` - column metadata (must match the query's output columns)
+- `table_id` - must reference a table that exists in the export
+- `database_id` - must reference a database that exists in the export
+
+## Editing result_metadata
+
+Each entry in `result_metadata` describes an output column. When changing a query's source table or fields, you must update result_metadata to match. Each field entry needs at minimum:
+- `name` - column name (e.g., `EMAIL`)
+- `base_type` - Metabase type (e.g., `type/Text`, `type/Integer`, `type/DateTime`)
+- `display_name` - human-readable name
+- `field_ref` - portable field reference
+- `id` - portable field path
+- `table_id` - portable table path
+- `source` - usually `fields`
+
+## Common Operations
+
+### Rename a card
+Change `name:` at the top level. Safe, no ref changes needed.
+
+### Change a card's source table
+Update all of these consistently:
+1. `table_id` - top-level
+2. `dataset_query.query.source-table` - in the query
+3. `result_metadata` - every field entry's `id`, `field_ref`, and `table_id`
+
+### Add a filter to a structured query
+```yaml
+dataset_query:
+  database: Sample Database
+  query:
+    source-table:
+    - Sample Database
+    - PUBLIC
+    - ORDERS
+    filter:
+    - ">"
+    - - field
+      - - Sample Database
+        - PUBLIC
+        - ORDERS
+        - TOTAL
+      - null
+    - 100
+  type: query
+```
+
+### Change visualization type
+```yaml
+display: bar    # was: table
+```
+Valid types: `table`, `bar`, `line`, `pie`, `scalar`, `row`, `area`, `combo`, `scatter`, `funnel`, `map`, `pivot`, `progress`, `gauge`, `waterfall`
+
+## Looking Up Valid References
+
+The export directory IS the reference catalog. When you need to find the correct name for a database, table, or field, look it up directly from the export.
+
+### List valid databases
+```bash
+ls databases/
+```
+Each entry is a database name (directory for serdes format, .yaml for concise format).
+
+### List valid tables for a database
+```bash
+ls databases/<db-name>/schemas/<schema>/tables/
+```
+Example: `ls databases/Sample\ Database/schemas/PUBLIC/tables/` shows `ACCOUNTS`, `ORDERS`, `PRODUCTS`, etc.
+
+### List valid fields for a table
+```bash
+ls databases/<db-name>/schemas/<schema>/tables/<table>/fields/
+```
+Example: `ls databases/Sample\ Database/schemas/PUBLIC/tables/PRODUCTS/fields/` shows `CATEGORY.yaml`, `TITLE.yaml`, `PRICE.yaml`, etc. The filename (minus `.yaml`) is the field name.
+
+### Find card entity IDs
+Card filenames encode the entity ID: `<entity-id>_<slug>.yaml`. The entity ID is the part before the first underscore (21 characters).
+
+## Self-Healing Loop
+
+When a checker reports errors, follow this loop:
+
+1. **Read the error message** - it tells you what's wrong and often suggests the fix
+2. **Look up the correct value** from the export directory (see "Looking Up Valid References" above)
+3. **Fix the YAML**
+4. **Re-run both checkers**
+5. **Repeat until clean**
+
+Do not guess at fixes. Always look up the correct value from the export.
+
+## Understanding Checker Errors
+
+### Structural checker errors
+
+The structural checker validates YAML shape against Malli schemas. Common errors:
+
+**Missing required key with typo suggestion:**
+```
+Missing required key 'name' - found 'nameee' which may be a typo
+```
+Fix: rename the typo'd key back to the correct name. The checker tells you what it expected and what it found.
+
+**Wrong type:**
+```
+'archived' should be a boolean, got: "yes"
+```
+Fix: use `true`/`false`, not strings.
+
+**Unknown key:**
+```
+Unknown key 'foobar' in card
+```
+Fix: remove the key, or check if it's a typo of a known key.
+
+### Cards checker errors
+
+The cards checker validates that queries resolve against exported metadata. Error types:
+
+**UNRESOLVED REFERENCES:**
+```
+UNRESOLVED REFERENCES:
+  - field: Sample Database.PUBLIC.PRODUCTS.CATEGORYYY
+```
+The dotted path tells you exactly which reference failed. Look up the correct value:
+- Last segment is the field name - check `databases/.../tables/<table>/fields/`
+- Third segment is the table name - check `databases/.../schemas/<schema>/tables/`
+- First segment is the database name - check `databases/`
+
+**ERROR (query construction failed):**
+```
+ERROR: Error creating query from legacy query: Invalid output: ...
+```
+Usually means the query structure is malformed. This often follows unresolved references - fix the refs first, then re-check.
+
+**ERROR (nil name):**
+```
+ERROR: Invalid output: {:name ["should be a string, got: nil"]}
+```
+The card is missing its `name` field (likely a structural issue that also affects the cards checker).
+
+### Exit codes
+
+- Exit 0: all checks passed
+- Exit 1: one or more failures
+
+## File Naming Convention
+
+Card files: `collections/<collection-path>/cards/<entity-id>_<slug>.yaml`
+
+The filename slug should match the card name (lowercase, underscored). If you rename a card, consider renaming the file to match, though import works on entity_id not filename.
+
+## What NOT to Edit
+
+- `entity_id` - this is the identity of the object, changing it creates a new object on import
+- `serdes/meta` - internal serdes metadata, leave it alone
+- `created_at` - timestamp, no reason to change
+- `creator_id` - email reference, leave it
+- `metabase_version` - informational, leave it

-          1. **Analyze the issue description and comments** - Understand what the issue is describing
-             a. Pay particular attention to reproduction steps and if there's an agreed upon fix.
-          2. **Search the codebase** - Use Grep and Glob tools to find relevant files
-          3. **Implement a fix** - Use the appropriate write skill based on the file types:
-             - Use clojure-write for Clojure/ClojureScript files
-             - Use typescript-write for TypeScript/JavaScript files
-             - Follow the coding standards and patterns in each skill
-          4. **Test the fix** - Run appropriate tests as specified in the skills
-          5. **Verify the fix** - Ensure tests pass and code follows conventions
-
-          ## Important Guidelines
-          - Use the appropriate write skill for the language you're working in
-          - Write failing tests first, then fix them
-          - Work in small, testable increments
-          - Don't commit changes - leave that for the workflow
-          - IMPORTANT: Focus only on fixing the reported bug, don't make unrelated changes
-
-          ## Scratchpad Directory
-          A `.claude-scratchpad/` directory has been created for your temporary files:
-          - Use this directory for ALL temporary verification files. However, prefer using production test files rather than adhoc ones.
-          - Only modify actual production code in the main repository directories
-          - The scratchpad will be cleaned up automatically - nothing from it will be committed
-
-          Start by understanding the bug and then systematically work toward a solution.
