# Create Plan

## Goal

Turn a user prompt into a **single, actionable plan** delivered in the final assistant message.

## Minimal workflow

Throughout the entire workflow, operate in read-only mode. Do not write or update files.

1. **Scan context quickly**
   - Read `README.md` and any obvious docs (`docs/`, `CONTRIBUTING.md`, `ARCHITECTURE.md`).
   - Skim relevant files (the ones most likely touched).
   - Identify constraints (language, frameworks, CI/test commands, deployment shape).

2. **Ask follow-ups only if blocking**
   - Ask **at most 1–2 questions**.
   - Only ask if you cannot responsibly plan without the answer; prefer multiple-choice.
   - If unsure but not blocked, make a reasonable assumption and proceed.

3. **Create a plan using the template below**
   - Start with **1 short paragraph** describing the intent and approach.
   - Clearly call out what is **in scope** and what is **not in scope** in short.
   - Then provide a **small checklist** of action items (default 6–10 items).
      - Each checklist item should be a concrete action and, when helpful, mention files/commands.
      - **Make items atomic and ordered**: discovery → changes → tests → rollout.
      - **Verb-first**: “Add…”, “Refactor…”, “Verify…”, “Ship…”.
   - Include at least one item for **tests/validation** and one for **edge cases/risk** when applicable.
   - If there are unknowns, include a tiny **Open questions** section (max 3).

4. **Do not preface the plan with meta explanations; output only the plan as per template**

## Plan template (follow exactly)

```markdown
# Plan

<1–3 sentences: what we’re doing, why, and the high-level approach.>

## Scope
- In:
- Out:

## Action items
[ ] <Step 1>
[ ] <Step 2>
[ ] <Step 3>
[ ] <Step 4>
[ ] <Step 5>
[ ] <Step 6>

## Open questions
- <Question 1>
- <Question 2>
- <Question 3>
```

## Checklist item guidance
Good checklist items:
- Point to likely files/modules: src/..., app/..., services/...
- Name concrete validation: “Run npm test”, “Add unit tests for X”
- Include safe rollout when relevant: feature flag, migration plan, rollback note

Avoid:
- Vague steps (“handle backend”, “do auth”)
- Too many micro-steps
- Writing code snippets (keep the plan implementation-agnostic)

## Objective
Conduct a thorough analysis of the entire repository to identify, prioritize, fix, and document ALL verifiable bugs, security vulnerabilities, and critical issues across any programming language, framework, or technology stack.

## Phase 1: Initial Repository Assessment

### 1.1 Architecture Mapping
- Map complete project structure (src/, lib/, tests/, docs/, config/, scripts/, etc.)
- Identify technology stack and dependencies (package.json, requirements.txt, go.mod, pom.xml, Gemfile, etc.)
- Document main entry points, critical paths, and system boundaries
- Analyze build configurations and CI/CD pipelines
- Review existing documentation (README, API docs, architecture diagrams)

### 1.2 Development Environment Analysis
- Identify testing frameworks (Jest, pytest, PHPUnit, Go test, JUnit, RSpec, etc.)
- Review linting/formatting configurations (ESLint, Prettier, Black, RuboCop, etc.)
- Check for existing issue tracking (GitHub Issues, TODO/FIXME/HACK/XXX comments)
- Analyze commit history for recent problematic areas
- Review existing test coverage reports if available

## Phase 2: Systematic Bug Discovery

### 2.1 Bug Categories to Identify
**Critical Bugs:**
- Security vulnerabilities (SQL injection, XSS, CSRF, auth bypass, etc.)
- Data corruption or loss risks
- System crashes or deadlocks
- Memory leaks or resource exhaustion

**Functional Bugs:**
- Logic errors (incorrect conditions, wrong calculations, off-by-one errors)
- State management issues (race conditions, inconsistent state, improper mutations)
- Incorrect API contracts or data mappings
- Missing or incorrect validations
- Broken business rules or workflows

**Integration Bugs:**
- Incorrect external API usage
- Database query errors or inefficiencies
- Message queue handling issues
- File system operation problems
- Network communication errors

**Edge Cases & Error Handling:**
- Null/undefined/nil handling

```

### 3.2 Prioritization Matrix
Rank bugs using:
- **Severity**: Critical > High > Medium > Low
- **User Impact**: Number of affected users/features
- **Fix Complexity**: Simple < Medium < Complex
- **Risk of Regression**: Low < Medium < High

## Phase 4: Fix Implementation

### 4.1 Fix Strategy
**For each bug:**
1. Create isolated fix branch (if using version control)
2. Write failing test FIRST (TDD approach)
3. Implement minimal, focused fix
4. Verify test passes
5. Run regression tests
6. Update documentation if needed

### 4.2 Fix Guidelines
- **Minimal Change Principle**: Make the smallest change that correctly fixes the issue
- **No Scope Creep**: Avoid unrelated refactoring or improvements
- **Preserve Backwards Compatibility**: Unless the bug itself is a breaking API
- **Follow Project Standards**: Use existing code style and patterns
- **Add Defensive Programming**: Prevent similar bugs in the future

### 4.3 Code Review Checklist
- [ ] Fix addresses the root cause, not just symptoms
- [ ] All edge cases are handled
- [ ] Error messages are clear and actionable
- [ ] Performance impact is acceptable
- [ ] Security implications considered
- [ ] No new warnings or linting errors introduced

## Phase 5: Testing & Validation

### 5.1 Test Requirements
**For EVERY fixed bug, provide:**
1. **Unit Test**: Isolated test for the specific fix
2. **Integration Test**: If bug involves multiple components
3. **Regression Test**: Ensure fix doesn't break existing functionality
4. **Edge Case Tests**: Cover related boundary conditions

### 5.2 Test Structure
```[language-specific]
describe('BUG-[ID]: [Bug description]', () => {
  test('should fail with original bug', () => {
    // This test would fail before the fix
    // Demonstrates the bug
  });
  
  test('should pass after fix', () => {
    // This test passes after the fix
    // Verifies correct behavior
  });
  
  test('should handle edge cases', () => {
    // Additional edge case coverage
  });
});
```

### 5.3 Validation Steps
1. Run full test suite: `[npm test | pytest | go test ./... | mvn test | etc.]`
2. Check code coverage changes
3. Run static analysis tools
4. Verify performance benchmarks (if applicable)
5. Test in different environments (if possible)

## Phase 6: Documentation & Reporting

### 6.1 Fix Documentation
