v0.4.0: 100% Progressive Disclosure Coverage
Major Achievement: All 29 production skills now have complete progressive disclosure with zero broken references. We created 110 new files across 17 skills in a comprehensive 7-hour sprint to achieve 100% completion.

The Journey
Starting from 41% completion with 116 missing files, we systematically completed progressive disclosure across all skills in 4 phases:
- Phase 0: Low Priority (7 skills, 20 files)
- Phase 1: Medium Priority (4 skills, 22 files)
- Phase 2: High Priority (4 skills, 30 files)
- Phase 3: Critical Priority (2 skills, 38 files)
What We Created
110 Files Total
- 54 reference guides - Comprehensive documentation
- 42 code examples - Working implementations across Python, TypeScript, Rust, Go
- 12 automation scripts - Token-free execution utilities
- 2 configuration assets - Templates and schemas
Complete Coverage Now Includes

Impact
This milestone means:
✅ All 29 skills are production-ready ✅ Zero broken references - every link works ✅ Progressive disclosure intact - efficient token usage ✅ Multi-language support - Python, TypeScript, Rust, Go ✅ Complete documentation - references for every pattern ✅ Working examples - copy-paste ready code ✅ Token-free scripts - automation without context cost
The Difference
Before: Skills had incomplete progressive disclosure, broken references, missing examples
After: Every skill has:
- SKILL.md (<500 lines) - Main skill file
- references/ - Detailed documentation files
- examples/ - Production-ready code
- scripts/ - Utility automation
What's Next
With all 29 frontend/backend skills complete, we're expanding to:
- DevOps Skills - CI/CD, infrastructure, deployment
- Security Skills - Auth, secrets, compliance
- Cloud Skills - AWS, GCP, Azure patterns
- AI/ML Skills - MLOps, embeddings, evaluation
See v0.4.1 release for details on 47 new skill master plans.
