### 2. Bug Ticket

```markdown
## [BUG-XXX] Fix: {Component} - {Symptom}

**Type:** Bug
**Priority:** {Critical | High | Medium | Low}
**Points:** {1 | 2 | 3 | 5}
**Labels:** {regression, ux-bug, data-bug, security-bug}
**Severity:** {Blocks users | Degrades experience | Cosmetic}

---

### Bug Summary
{One sentence: what is broken and who is affected.}

### Environment
- Browser/OS: {e.g., Chrome 120 / macOS 14.2}
- Environment: {Production | Staging | Local}
- User type: {Anonymous | Authenticated | Admin}
- First observed: {date}

### Steps to Reproduce
1. {Navigate to / perform action}
2. {Perform next action}
3. {Perform next action}
4. **Observe:** {incorrect behavior}

### Expected Behavior
{What should happen instead.}

### Actual Behavior
{What actually happens. Include error messages, console output, screenshots.}

### Impact
- Users affected: {percentage or count}
- Frequency: {every time | intermittent | specific conditions}
- Workaround: {exists / none}

---

### Claude Code Context

#### Suspected Root Cause
{Where the bug likely lives, if known.}
- File: `src/components/LoginForm.tsx:87`
- Issue: `isSubmitting` state set to `true` on validation error but never reset

#### Relevant Files
- `src/components/LoginForm.tsx` - Form component with the bug
- `tests/components/LoginForm.test.tsx` - Existing tests (gap here)
- `src/hooks/useAuth.ts` - Auth hook used by the form

#### Test Gap Analysis
- Existing tests cover: {what's currently tested}
- Missing test: {what test would have caught this bug}

#### Bug Fix Workflow (TDD)
1. Write a failing test that reproduces the bug
2. Verify the test fails (confirms the bug exists)
3. Fix the bug with minimum code change
4. Verify the test passes
5. Run full test suite to check for regressions

#### Verification
```bash
# Run the specific test
npm test -- --grep "LoginForm submit"

# Run related tests
npm test -- src/components/LoginForm.test.tsx

# Full regression check
npm test

### 3. Tech Debt Ticket

```markdown
## [TECH-XXX] Refactor: {Area} - {Improvement}

**Type:** Tech Debt
**Priority:** {High | Medium | Low}
**Points:** {3 | 5 | 8}
**Labels:** {refactor, performance, maintainability, testing}

---

### Problem Statement
{What is wrong with the current implementation and why it matters.
Include concrete pain points: slow CI, frequent bugs, developer confusion.}

### Current State
- File: `{path}` ({N} lines)
- Test coverage: {X}%
- Cyclomatic complexity: {N}
- Related bugs: {PROJ-XXX, PROJ-YYY}
- Pain frequency: {how often this causes issues}

### Proposed Change
{What specifically should change and why this approach.}

### Acceptance Criteria
- [ ] {Specific structural change completed}
- [ ] All existing tests pass without modifying test assertions
- [ ] No public API changes (existing consumers unaffected)
- [ ] Test coverage >= {X}%
- [ ] {Measurable improvement metric}

### Risk Assessment
- Risk level: {Low | Medium | High}
- Mitigation: {run full regression, deploy behind flag, etc.}

### Business Justification
{Why this is worth doing now. E.g., "Reduces average bug fix time from 4h to 1h"
or "Enables upcoming feature PROJ-XXX which requires clean separation."}

---

### Claude Code Context

#### Relevant Files
- `{file}` - Current implementation to refactor
- `{test file}` - Existing tests (must not break)
- `{dependent file}` - Consumer of the API being refactored

#### Pattern Reference
Follow the pattern established in `{good example file}` for the new structure.

#### Constraints
- Do NOT change public APIs or exports
- Do NOT modify test assertions (tests should pass as-is)
- Do NOT introduce new dependencies
- Keep backwards compatibility

#### Verification
```bash
# Existing tests must pass unchanged
npm test

# No type errors
npm run typecheck

# Lint clean
npm run lint

# Coverage target
npm test -- --coverage

### Slicing Strategy
{How the epic was broken down. Reference the technique used.}

- Feature Agent 2: Tickets #3, #4
- Parallel execution: #1 and #3 can run simultaneously
- Sequential: #2 depends on #1, #4 depends on #2 and #3

Title: Fix login
Description: (empty)

Title: Implement new onboarding
Description: (3 pages mixing UI, backend, analytics, email, and future ideas)

Acceptance Criteria:
- Should be fast
- UX should be good
- Should work on mobile

Title: Use Redis to cache user sessions
Description: Install Redis, configure connection pooling, set TTL to 3600...

Description: Update the auth module to support OAuth.

Acceptance Criteria:
- OAuth login works
- Users can sign in with Google

Title: Add rate limiting to the API
Description: We need rate limiting on our endpoints.

Title: Add sliding window rate limiter to /api/generate endpoint

User Story:
As an API consumer, I want requests to be rate-limited
so that the service remains available under heavy load.

Acceptance Criteria:
AC1: Given an authenticated user making requests,
     when they exceed 10 requests per minute,
     then return 429 with Retry-After header.

AC2: Given a rate-limited user,
     when the window expires,
     then requests succeed again.

AC3: Given an unauthenticated request,
     when it hits /api/generate,
     then return 401 (rate limiting only applies to authed users).

Claude Code Context:
- Pattern: Follow `src/middleware/throttle.ts` for middleware structure
- File: Create `src/middleware/rateLimit.ts`
- Test: Create `tests/middleware/rateLimit.test.ts`
- Route: Modify `src/api/routes/generate.ts` to add middleware
- Constraint: Do NOT modify existing middleware or other endpoints

Verification:
  npm test -- --grep "rate-limit"
  npm run lint
  npm run typecheck

1. Create ticket using templates above
2. Ticket becomes the feature spec in _project_specs/features/
