# Implementation Planning

## Epic Breakdown Required

Requirements must be decomposed into epics and bite-sized stories (200k context limit per story). Each story should be:
- **Testable**: Clear acceptance criteria
- **Independent**: Minimal dependencies on other stories
- **Valuable**: Delivers user-facing functionality or technical enabler
- **Estimable**: Complexity understood
- **Small**: Implementable in reasonable time (<1 week)

**Next Step**: Run `*create-epics-and-stories` workflow to create the implementation breakdown.

## Innovation Validation Approach

The core innovations (3-tool semantic discovery and OpenAPI-driven architecture) require validation to ensure they deliver expected value:

### Semantic Search Effectiveness Validation

**Hypothesis**: Natural language semantic search with threshold ≥0.7 will enable users to discover 90%+ of relevant operations without knowing exact API terminology.

**Validation Experiments**:
1. **A/B Testing Semantic Thresholds**:
   - Test similarity thresholds: 0.6 vs 0.7 vs 0.8
   - Measure: precision (% relevant results), recall (% relevant operations found), user satisfaction
   - Sample queries: "list queues", "delete exchange", "consume messages", "check server status"
   - Success criterion: threshold 0.7 achieves >85% precision and >80% recall

2. **User Discovery Time Study**:
   - Measure time to complete common tasks using semantic search vs traditional API documentation
   - Tasks: "Find how to list all queues", "Discover message consumption API", "Locate binding operations"
   - Sample size: 10 early adopters (5 RabbitMQ experts, 5 novices)
   - Success criterion: 50%+ faster task completion with semantic search

3. **Query Pattern Analysis**:
   - Collect first 100 real user queries (anonymized)
   - Analyze: query patterns, failed searches (threshold <0.7), disambiguation requests
   - Iterate on embeddings or documentation if patterns show >15% failed searches
   - Success criterion: <10% of queries return zero results

### OpenAPI-Driven Architecture Validation

**Hypothesis**: Build-time code generation from OpenAPI reduces maintenance burden and keeps implementation synchronized with RabbitMQ API changes.

**Validation Metrics**:
1. **Generation Pipeline Performance**:
   - Measure: time to regenerate all artifacts (schemas, operations, embeddings)
   - Benchmark: <5 minutes for complete regeneration
   - Validate: generated code passes 100% of type checks and tests

2. **API Version Migration Testing**:
   - Test migration from RabbitMQ 3.11 → 3.12 → 3.13
   - Measure: time required, manual changes needed, breaking changes detected
   - Success criterion: <30 minutes to support new API version

3. **Coverage Verification**:
   - Verify: 100% of OpenAPI operations are discoverable via search-ids
   - Validate: all operations have embeddings and documentation
   - Test: can execute any operation via call-id

### Early Adopter Feedback Collection

**Timeline**: First 30 days after MVP release

**Collection Methods**:
1. **User Research Sessions** (n=5-10):
   - 30-minute sessions observing users completing tasks
   - Questions: "What operations did you search for?", "Were results relevant?", "What was confusing?"
   - Document: pain points, feature requests, usability issues

2. **Telemetry Analysis** (if users opt-in):
   - Track: most searched operations, search success rate, operation execution patterns
   - Identify: common workflows, underutilized features, error hotspots
   - Privacy: anonymized data only, opt-in telemetry, GDPR compliant

3. **Community Feedback Channels**:
   - GitHub issues/discussions: feature requests, bug reports
   - Survey: post-first-use survey (5 questions, <2 minutes)
   - Success metrics: NPS score >30, 80%+ would recommend

**Iteration Plan**: Review validation data at 7 days, 14 days, 30 days. Prioritize improvements based on impact (high usage, high friction points).

## Test-Driven Development Mandate

All implementation MUST follow TDD workflow:
1. **Red**: Write tests first (unit, integration, contract)
2. **Approve**: Tests reviewed and approved
3. **Fail**: Tests fail (red state)
4. **Green**: Implementation makes tests pass
5. **Refactor**: Improve code while keeping tests green
6. **Checkpoint**: Review and document progress

**Coverage Targets**:
- Overall: 80%+ code coverage
- Critical paths: 95%+ coverage (authentication, operations, safety validations)
- Authentication flows: 100% coverage
- Error handling: 100% coverage
- MCP protocol compliance: 100% coverage

## Quality Gates

**Pre-Commit**:
- Black code formatting
- isort import sorting
- mypy type checking
- pylint linting
- No linting warnings allowed

**CI/CD Pipeline**:
- All tests pass (unit, integration, contract, performance)
- 80%+ code coverage achieved
- No security vulnerabilities (bandit scan)
- No credential leaks detected (automated scanning)
- OpenAPI artifacts synchronized

**Release Criteria**:
- All acceptance criteria met for MVP specs (001-008)
- Zero critical/high security issues
- Performance benchmarks met (<100ms search, <200ms operations)
- Documentation complete (README, API reference, architecture, examples)
- Community resources ready (contribution guide, issue templates, PR template)
