Lessons Learned

What Went Well

1. Structured Approach: Breaking sprint into 8 clear tasks enabled systematic progress
2. Template Reuse: Orchestrator.md template accelerated remaining 7 service docs
3. Comprehensive Examples: Each deliverable includes multiple code examples in 3 languages
4. Dual SDK Support: TypeScript SDK + Python examples provide broad language coverage
5. Testing Collections: Postman/Insomnia collections enable immediate API testing without custom scripts
6. Visual Documentation: Mermaid diagrams make complex architecture accessible

Challenges Encountered

1. Initial Scope: Initial estimate underestimated documentation depth (~7k lines estimated, ~21k actual)
2. Context Limits: Required strategic batching across multiple conversation sessions
3. Consistency: Maintaining consistent format and terminology across 50 files required vigilance
4. Template Evolution: Template improved during sprint, requiring retroactive updates

Process Improvements for Next Sprint

1. Batch Commits: Commit after each major task instead of holding multiple tasks
2. Progressive Disclosure: Start with high-level docs, add details iteratively
3. Template First: Create and validate templates before bulk file creation
4. Automated Validation: Add scripts to verify link integrity, code syntax, schema compliance
5. Example Testing: Actually run code examples against services to verify correctness

Impact and Value

Developer Onboarding

Before Sprint 0.5:

• Comprehensive Docs: 13,452 lines of human-readable documentation
• Visual Understanding: 6 Mermaid diagrams explaining complex flows
• Code Examples: 60+ examples in 3 languages (Python, TypeScript, Bash)

Estimated Time Saved: 10-15 hours per new developer joining the project
