Evolution Skills
Self-evolving skills for AI coding assistants.
AI 编程助手的自我进化技能系统。

Preface
Use only the skills you actually need. MCPs consume context, and skills consume context too.
This system exists to help you build skills that solve your real work, not to wrap generic content from the internet.
From personal experience, attention quality drops sharply beyond ~65k tokens, and default system/tool prompts can eat ~20k.
If this is too long, just paste this GitHub link into your AI and ask how to use it.
What It Is
Evolution Skills is a documentation-first skill system for AI coding assistants. It ships structured specs and command templates that help capture reusable patterns, track their health, and keep guidance aligned with project style and framework versions.
Packages:
- Claude Code:
claude-code/
- Factory Droid:
factory-droid/
Why It Matters
- Preserve hard-won solutions as reusable patterns.
- Self-correct when suggestions fail.
- Build an automation-friendly learning loop so guidance improves with real usage.
- Track pattern health with deterministic rules.
- Adapt to project style and version constraints.
Feature Highlights
| Capability | What it does | Where to learn more |
|---|
| Pattern capture | Save new patterns with /evolve | claude-code/README.md, factory-droid/README.md |
| Health reporting | Aggregate feedback markers via /skills-health | claude-code/README.md, factory-droid/README.md |
| Validation | Validate skills content with /validate-skills | claude-code/README.md |
| Version adaptation | Choose guidance based on detected versions | claude-code/README.md, factory-droid/README.md |
| Style profiling | Align output to project conventions | claude-code/README.md, factory-droid/README.md |

Automation-friendly:
Quick Start
Claude Code
cp -r claude-code/skills/* ~/.claude/skills/
cp -r claude-code/commands/* ~/.claude/commands/
Then run:
/evolve
/skills-health
/validate-skills
Factory Droid
cp -r factory-droid/skills/* ~/.factory/skills/
cp -r factory-droid/commands/* ~/.factory/commands/
cp -r factory-droid/droids/* ~/.factory/droids/ # optional
Then run:
/evolve
/skills-health
Command Overview
| Command | Claude Code | Factory Droid | Purpose |
|---|
/evolve | Yes | Yes | Save learned knowledge |
/skills-health | Yes | Yes | Show health report |
/validate-skills | Yes | No | Validate skills accuracy |
Usage Guidance
Recommended workflow:
- Solve a real issue, then run
/evolve while context is fresh.
- Review
/skills-health regularly to find drift or failing patterns.
- (Claude Code) Run
/validate-skills after skill updates.
Authoring principles:
- Keep patterns small and specific (one problem, one pattern).
- Write constraints explicitly (version, style, environment).
- Prefer deterministic checks and clear success criteria.
Use Cases
- Capture a verified troubleshooting fix after resolving a build failure.
- Standardize a UI pattern across multiple projects.
- Keep guidance aligned with framework version upgrades.
- Detect stale patterns using health signals.
Automation & Learning Loop
- Capture: validated fixes are saved via
/evolve.
- Normalize: entries are deduped and tagged with metadata.
- Monitor: health is tracked through deterministic
feedback rules.
- Improve: patterns are updated or retired as failures accumulate.

This repo provides the specs and command templates. The assistant runtime applies them and writes entries as Markdown with metadata blocks.
