+name: ln-340-story-quality-gate
+description: Story-level quality orchestrator. Pass 1: code quality -> regression -> manual testing (fail fast). Pass 2: verify tests/coverage -> mark Story Done. Auto-discovers team/config.
+---
+
+# Story Quality Gate
+
+Two-pass Story review that fails fast, creates needed fix/refactor/test tasks, and finalizes the Story only after tests are verified.
+
+## Purpose & Scope
+- Pass 1 (after impl tasks Done): run code-quality, lint, regression, and manual testing; if all pass, create/confirm test task; otherwise create targeted fix/refactor tasks and stop.
+- Pass 2 (after test task Done): verify tests/coverage/priority limits and close Story to Done or create fix tasks.
+- Delegates work to 341/342/343 workers and ln-350-story-test-planner; invoked by ln-330-story-executor.
+
+## When to Use
+- Pass 1: all implementation tasks Done; test task missing or not Done.
+- Pass 2: test task exists and is Done.
+- Explicit `pass` parameter can force 1 or 2; otherwise auto-detect by test task status.
+
+## Workflow (concise)
+- **Phase 1 Discovery:** Auto-discover team/config; select Story; load Story + task metadata (no descriptions), detect test task status.
+- **Pass 1 flow (fail fast):**
+  1) Invoke ln-341-code-quality-checker. If issues -> create refactor task (Backlog), stop.
+  2) Run all linters from tech_stack.md. If fail -> create lint-fix task, stop.
+  3) Invoke ln-342-regression-checker. If fail -> create regression-fix task, stop.
+  4) Invoke ln-343-manual-tester. If fail -> create bug-fix task, stop.
+  5) If all passed: if no test task exists, auto-call ln-350-story-test-planner (autoApprove) to create test task; if test task exists and Done, jump to Pass 2; if exists but not Done, report status and stop.
+- **Pass 2 flow (after test task Done):**
+  1) Load Story/test task; read test plan/results and manual testing comment from Pass 1.
+  2) Verify limits and priority: Priority ≤15; E2E 2-5, Integration 0-8, Unit 0-15, total 10-28; tests focus on business logic (no framework/DB/library tests).
+  3) Ensure Priority ≤15 scenarios and Story AC are covered by tests; infra/docs updates present.
+  4) If pass -> mark Story Done in Linear; minimal kanban cleanup if needed. If fail -> create fix tasks (Backlog) and stop; ln-330 will loop.
+
+## Critical Rules
+- Early-exit: any failure creates a specific task and stops Pass 1/2.
+- Single source of truth: rely on Linear metadata for tasks; kanban is updated by workers/ln-330.
+- Task creation via skills only (ln-350/ln-311); this skill never edits tasks directly.
+- Pass 2 only runs when test task is Done; otherwise return error/status.
+- Language preservation in comments (EN/RU).
+
+## Definition of Done
+- Pass 1: 341 pass OR refactor task created; linters pass OR lint-fix task created; 342 pass OR regression-fix task created; 343 pass OR bug-fix task created; if all pass, test task created (if missing) or status reported; exits.
+- Pass 2: test task verified (priority/limits/coverage/infra/docs); Story set to Done in Linear (if pass) or fix tasks created (if fail); kanban minimally cleaned if needed.
+- Summary/comment posted in Linear for actions taken.
+
+## Reference Files
+- Workers: `../ln-341-code-quality-checker/SKILL.md`, `../ln-342-regression-checker/SKILL.md`, `../ln-343-manual-tester/SKILL.md`
+- Test planning: `../ln-350-story-test-planner/SKILL.md`
+- Tech stack/linters: `docs/project/tech_stack.md`

+
+---
+
+### Risk Assessment for Test Planning
+
+**Purpose:** Provide Priority scores for ln-350-story-test-planner to select tests based on business risk
+
+| Scenario | Type | Business Impact (1-5) | Probability (1-5) | Priority | Reason |
+|----------|------|----------------------|-------------------|----------|--------|
+| [AC1: AC title] | AC | [1-5] | [1-5] | [Result] | [Why this impact/probability] |
+| [AC2: AC title] | AC | [1-5] | [1-5] | [Result] | [Why this impact/probability] |
+| [Edge Case 1: description] | Edge Case | [1-5] | [1-5] | [Result] | [Why this impact/probability] |
+| [Edge Case 2: description] | Edge Case | [1-5] | [1-5] | [Result] | [Why this impact/probability] |
+| [Error: HTTP 400 scenario] | Error Handling | [1-5] | [1-5] | [Result] | [Why this impact/probability] |
+| [Error: HTTP 401 scenario] | Error Handling | [1-5] | [1-5] | [Result] | [Why this impact/probability] |
+
+**Priority Calculation:** Priority = Business Impact (1-5) × Probability (1-5)
+
+**Decision Criteria:**
+- Priority ≥15 → MUST test (ln-350-story-test-planner will create automated tests)
+- Priority 9-14 → SHOULD test if not already covered
+- Priority ≤8 → SKIP (manual testing sufficient)
+
+**Reference:** See `ln-350-story-test-planner/references/risk_based_testing_guide.md` for complete Business Impact/Probability scoring tables and methodology.
+
+**Total Scenarios:** [X scenarios], **Priority ≥15:** [Y scenarios] (will be tested)
+```
+
+## Usage Instructions
+
+### For ln-343-manual-tester (Phase 5 Step 1)
+
+1. **Copy template structure** (do NOT include this instruction section)
+2. **Fill required fields:**
+   - Story ID from Linear
+   - Current date in YYYY-MM-DD format
+   - Status calculated from AC pass/fail count
+3. **Extract AC from Story description:**
+   - Copy Given-When-Then exactly as written in Story
+   - Maintain numbering (AC1, AC2, AC3...)
+4. **Document test results for EACH AC:**
+   - Include full curl command or puppeteer code used
+   - Copy exact HTTP status codes and response bodies
+   - Note any deviations from expected behavior
+5. **List ALL edge cases discovered** during testing:
+   - Enumerate sequentially (1, 2, 3...)
+   - Provide concrete input/expected/actual values
+6. **Create error handling table:**
+   - Test all error codes mentioned in Story Technical Notes
+   - Include 400, 401, 404, 500 at minimum
+   - Mark ⚠️ for codes not testable without setup
+7. **Verify integration flow:**
+   - Trace request through all architectural layers
+   - Note any transaction/rollback behavior
+8. **Write summary:**
+   - Count passed AC vs total AC
+   - Recommend next action (ln-350-story-test-planner or refactoring task)
+
+### For ln-350-story-test-planner (Phase 2 Step 1)
+
+**Parsing strategy:**
+
+1. **Find comment with marker:**
+   - Search for `## 🧪 Manual Testing Results`
+   - Verify `**Format Version:** 1.0` present
+
+2. **Extract sections using regex:**
+   - `^### Acceptance Criteria` → parse AC with Given-When-Then
+   - `^### Test Results by AC` → extract status, method, results per AC
+   - `^### Edge Cases Discovered` → parse numbered list items
+   - `^### Error Handling Verified` → parse markdown table
+   - `^### Integration Testing` → extract component flows
+
+3. **Map to test design:**
+   - Each PASSED AC → 1 E2E test (copy method from "Method:" field)
+   - Each edge case → Unit or Integration test
+   - Each verified error code → Error handling test
+   - Integration flow → Integration test suite
+
+4. **Handle parsing errors:**
+   - Missing Format Version → warn user, try legacy parsing
+   - Missing required section → error with clear message
+   - Cannot parse AC → request Story description fix
+
+## Examples
+
+### Example 1: API Endpoint Testing
+
+```markdown
+## 🧪 Manual Testing Results
+
+**Format Version:** 1.0
+**Story ID:** US042
+**Tested By:** ln-343-manual-tester
+**Date:** 2025-10-31
+**Status:** ✅ PASSED (3/3 AC)
+
+---
+
+### Acceptance Criteria (from Story)
+
+**AC1:** User can login with valid credentials
+- **Given:** Valid email and password
+- **When:** User submits login form
+- **Then:** Returns 200 OK with JWT token
+
+**AC2:** Invalid credentials are rejected
+- **Given:** Invalid email or password
+- **When:** User submits login form
+- **Then:** Returns 401 Unauthorized with error message
+
+**AC3:** Rate limiting prevents brute force
+- **Given:** More than 5 failed login attempts within 1 minute
+- **When:** User submits 6th attempt
+- **Then:** Returns 429 Too Many Requests
+
+---
+
+### Test Results by AC
+
+**AC1: User can login with valid credentials**
+- ✅ **Status:** PASS
+- **Method:** `curl -X POST http://localhost:8000/api/auth/login -H "Content-Type: application/json" -d '{"email":"test@example.com","password":"SecurePass123"}'`
+- **Result:** 200 OK, JWT token received: `eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...`
+- **Notes:** Token validated successfully, expires in 1 hour
+
+**AC2: Invalid credentials are rejected**
+- ✅ **Status:** PASS
+- **Method:** `curl -X POST http://localhost:8000/api/auth/login -H "Content-Type: application/json" -d '{"email":"test@example.com","password":"WrongPassword"}'`
+- **Result:** 401 Unauthorized, `{"error":"Invalid credentials"}`
+- **Notes:** Error message does not reveal if email or password is wrong (good security practice)
+
+**AC3: Rate limiting prevents brute force**
+- ✅ **Status:** PASS
+- **Method:** Bash loop: `for i in {1..6}; do curl -X POST http://localhost:8000/api/auth/login -d '{"email":"test@example.com","password":"wrong"}'; done`
+- **Result:** First 5 attempts → 401, 6th attempt → 429 with `{"error":"Too many requests, try again in 52 seconds"}`
+- **Notes:** Rate limit counter resets correctly after 1 minute
+
+---
+

+await page.click('[data-category="electronics"]');
+await page.waitForTimeout(500); // Wait for filter animation
+const filteredProducts = await page.$$('.product-card[data-category="electronics"]');
+console.log(`Filtered to ${filteredProducts.length} electronics`);
+```
+- **Result:** Filter works, showing only 5 electronics products. Other categories hidden.
+- **Notes:** Filter animation smooth, no flickering
+
+---
+
+### Edge Cases Discovered
+
+1. **Empty category returns "No products" message**
+   - **Input:** Click category "Books" (which has 0 products)
+   - **Expected:** Show "No products found" message
+   - **Actual:** Message displayed correctly with suggestion to clear filters
+   - ✅ **Status:** PASS
+
+2. **Multiple rapid filter clicks**
+   - **Input:** Click different category filters rapidly 5 times
+   - **Expected:** UI remains stable, shows final selection
+   - **Actual:** No race conditions, final filter applied correctly
+   - ✅ **Status:** PASS
+
+---
+
+### Error Handling Verified
+
+| HTTP Code | Scenario | Error Message | Verified |
+|-----------|----------|---------------|----------|
+| 404 | Navigate to /products/invalid-id | "Product not found" page | ✅ |
+| 500 | API returns error | "Failed to load products" toast | ⚠️ Not tested (requires API mock failure) |
+
+---
+
+### Integration Testing
+
+**Frontend → API → Backend Flow:**
+- ✅ React component fetches from /api/products on mount
+- ✅ API returns JSON with product array
+- ✅ Product images loaded from CDN correctly
+- ✅ Category filter sends query param ?category=electronics
+- ✅ React state updates trigger re-render without full page reload
+
+---
+
+### Summary
+
+**Overall Result:** ✅ **ALL ACCEPTANCE CRITERIA PASSED**
+
+**Coverage:**
+- 2/2 AC verified ✅
+- 2 edge cases tested ✅
+- 1/2 error scenarios verified ✅
+- Integration flow validated ✅
+
+**Recommendation:** Proceed to test task creation via ln-350-story-test-planner

+# Story Review Checklist (14 Points)
+
+Complete checklist for validating User Story after all tasks are Done.
+
+## A. Goal Achievement (CRITICAL)
+
+### 1. Story Statement Fulfilled
+
+**Check:**
+- [ ] "As a [role]" - Does role get needed functionality?
+- [ ] "I want [capability]" - Is capability fully implemented?
+- [ ] "So that [value]" - Is business value delivered?
+
+**Method:**
+- Code review of implemented functionality
+- Run E2E tests covering Story goal
+- Validate user can achieve stated goal
+
+**Red Flags:**
+- Story goal partially implemented
+- Business value not delivered
+- Role cannot use functionality as intended
+
+---
+
+### 2. All Story AC Satisfied
+
+**Check:**
+- [ ] Main Scenarios: All Given-When-Then scenarios work
+- [ ] Edge Cases: All boundary conditions handled
+- [ ] Error Handling: All error scenarios handled correctly
+
+**Method:**
+- Compare Story AC (from Story description) with E2E tests
+- Verify each Given-When-Then has corresponding E2E test
+- Run all E2E tests - all must pass
+
+**Red Flags:**
+- Story AC missing E2E test coverage
+- E2E tests fail
+- Edge cases not handled
+
+---
+
+## B. Integration Quality (CRITICAL)
+
+### 3. Tasks Integrated Correctly
+
+**Check:**
+- [ ] API → Service → Repository integration works
+- [ ] Contracts between layers honored (types, parameters match)
+- [ ] Data flow correct (no data loss, no corruption)
+- [ ] External dependencies integrated (APIs, databases)
+
+**Method:**
+- Code review of integration points
+- Run Integration tests - all must pass
+- Check types match between layers
+
+**Red Flags:**
+- Type mismatches (API sends `string`, Service expects `number`)
+- Missing integration (API doesn't call Service)
+- Integration tests fail
+
+**Example Problem:**
+```
+Task 1 Done: API endpoint accepts user_id: string ✅
+Task 2 Done: Service expects userId: number ✅
+Problem: API calls Service with string → Runtime error ❌
+```
+
+---
+
+### 4. No Gaps Between Tasks
+
+**Check:**
+- [ ] All components are used (no orphaned methods)
+- [ ] All necessary calls present (no missing calls)
+- [ ] Component dependencies satisfied
+
+**Method:**
+- Grep for unused functions/classes in Story files
+- Code review for missing calls
+- Check all Affected Components from tasks are integrated
+
+**Red Flags:**
+- Unused methods (created but never called)
+- Missing calls (Service method exists but API doesn't call it)
+- Dead code
+
+**Example Problem:**
+```
+Task 1 Done: sendEmail() function created ✅
+Task 2 Done: saveUser() function created ✅
+Problem: API endpoint calls saveUser() but NOT sendEmail() → Email not sent ❌
+```
+
+---
+
+## C. Overall Code Quality
+
+### 5. Patterns Consistent
+
+**Check:**
+- [ ] All tasks use same approaches (async/await vs callbacks)
+- [ ] No code duplication between tasks (DRY at Story level)
+- [ ] Error handling consistent across tasks
+- [ ] Architecture coherent
+- [ ] Configuration management consistent (no hardcoded values, no magic numbers)
+
+**Method:**
+- Grep for similar code patterns across Story files
+- Code review for duplication
+- Check error handling patterns match
+
+**Red Flags:**
+- Task 1 uses async/await, Task 2 uses callbacks
+- Same validation logic duplicated in 3 tasks
+- Inconsistent error handling (Task 1 throws, Task 2 returns null)
+- Magic numbers or hardcoded URLs in code (should be in config)
+
+---
+
+### 6. Following guides/
+
+**Check:**
+- [ ] Story implemented per project patterns (from guides/)
+- [ ] Technical Notes from Story executed
+- [ ] Architectural patterns followed
+
+**Method:**
+- Compare implementation with guides/ referenced in Story
+- Check Technical Notes section of Story
+- Verify patterns match guide examples
+
+**Red Flags:**
+- Story says "Use Repository Pattern" but implementation uses direct DB calls
+- Technical Notes mention caching but no cache implemented
+
+---
+
+## D. Testing & Coverage (CRITICAL)
+
+### 7. All Story Tests Pass
+
+**Check:**
+- [ ] Unit tests (70%) pass
+- [ ] Integration tests (20%) pass
+- [ ] E2E tests (10%) pass
+- [ ] No flaky tests (all deterministic)
+- [ ] Tests focus on business logic (not frameworks/libraries/getters)
+- [ ] No test duplication - Each behavior tested once at pyramid level
+
+**Method:**
+- Run all tests for Story files: `npm test` / `pytest` / `go test`
+- Check test output - 0 failures
+
+**Red Flags:**
+- Any test fails
+- Flaky tests (pass sometimes, fail sometimes)
+- Tests skipped
+
+---
+
+### 8. Coverage Story ≥80%
+
+**Check:**
+- [ ] Overall coverage across all Story files ≥80%
+- [ ] Integration layer covered (not just unit level)
+- [ ] Critical paths covered
+
+**Method:**
+- Run coverage report for Story files
+- Check overall percentage
+- Review uncovered lines (should be non-critical)
+
+**Red Flags:**
+- Coverage <80%
+- Critical business logic uncovered
+- Integration points uncovered
+
+**Example:**
+```
+Task 1 coverage: 90% ✅
+Task 2 coverage: 85% ✅
+Task 3 coverage: 80% ✅
+But: Story coverage: 65% ❌ (integration layer uncovered)
+```
+
+---
+
+### 9. Test Limits and Priority Scenarios
+
+**Check:**
+- [ ] Test count within limits: 2-5 E2E, 3-8 Integration, 5-15 Unit (10-28 total)
+- [ ] All Priority ≥15 scenarios from manual testing tested
+- [ ] No duplicate test coverage (each test adds unique business value)
+- [ ] Trivial code skipped (simple CRUD, framework code, getters/setters)
+
+**Method:**
+- Count tests by type for Story
+- Verify total tests 10-28
+- Check Risk Priority Matrix in test task - ensure all Priority ≥15 scenarios have tests
+- Verify no tests for frameworks, libraries, or trivial logic
+
+**Red Flags:**
+- Total tests exceed 28 (maintenance burden)
+- Priority ≥15 scenarios not tested (critical paths uncovered)
+- Tests for framework code or trivial logic (waste of time)
+- Duplicate coverage (same scenario tested at multiple levels)
+
+---
+
+### 10. E2E Cover All Story AC
+
+**Check:**
+- [ ] Each Main Scenario from Story AC has E2E test
+- [ ] Edge Cases from Story AC covered by E2E
+- [ ] Error Handling from Story AC covered by E2E
+
+**Method:**
+- List all Story AC (Given-When-Then scenarios)
+- List all E2E tests
+- Match AC to E2E tests (1:1 mapping for main scenarios)
+
+**Red Flags:**
+- Story AC without corresponding E2E test
+- E2E test doesn't match Story AC wording
+- Critical AC not covered
+
+**Example Problem:**
+```
+Story AC: "Given user submits form, When submit, Then data saved AND email sent"
+E2E test: "test_user_can_save_data" ✅ (covers save)
+Missing: E2E test for email sent ❌
+```
+
+---
+
+## E. Guides & Infrastructure (NEW)
+
+### 11. Guides Correct
+
+**Check:**
+- [ ] All guides/ created in Story are correct

+
+**Method:**
+- Identify guides/ created/modified in Story tasks
+- Review each guide structure matches guide_template.md
+- Verify patterns are actually used in codebase
+- Check examples are correct and runnable
+
+**Red Flags:**
+- Guide template not followed
+- Pattern documented but not used in code

+
+**Red Flags:**
+- Package added but package.json not committed
+- Package needs system library but Dockerfile not updated
+- Package needs Redis but docker-compose.yml not updated
