Auto-Skill Plugin
This plugin automatically detects workflow patterns from your coding agent sessions, generates reusable skills, and can load them dynamically mid-session.
CLI Tool Installation
The agent skills are now installed, but to use CLI commands like auto-skill init, auto-skill discover, etc., you need to install the npm package.
Quick Install:
# Option 1: Run the included install script bash ~/.agents/skills/auto-skill-guide/install-cli.sh # Option 2: Install globally via npm npm install -g @matrixy/auto-skill # Option 3: Use without installing (via npx) npx @matrixy/auto-skill init
Verify: auto-skill version
How It Works
Session 1: Grep → Read → Edit ─┐ Session 2: Grep → Read → Edit ├──▶ Pattern Detected → SKILL.md Session 3: Grep → Read → Edit ─┘
- •Observation: Every tool call is recorded via PostToolUse hook
- •Detection: Patterns are analyzed for repetition (3+ occurrences)
- •Generation: Approved patterns become SKILL.md files with proper frontmatter
- •Discovery: Claude proactively offers relevant skills for your tasks
- •Loading: Skills can be loaded mid-session without restart
Commands
/auto-skill:review
Review and approve detected patterns:
/auto-skill:review # List all detected patterns /auto-skill:review preview ID # Preview a pattern as a skill /auto-skill:review approve ID # Generate skill from pattern /auto-skill:review reject ID # Dismiss a pattern
/auto-skill:load
Load a generated skill into the current session:
/auto-skill:load # List available skills /auto-skill:load <name> # Load specific skill immediately
Skills loaded this way become active immediately without requiring a session restart.
/auto-skill:status
Show system diagnostics:
/auto-skill:status # Display stats, patterns, and config
Pattern Detection
Patterns are detected when:
- •Same tool sequence appears 3+ times across sessions
- •Sequence is 2-10 tools long
- •Pattern has occurred within the last 7 days
Confidence Scoring
| Factor | Weight | Description |
|---|---|---|
| Occurrences | 40% | More occurrences = higher confidence |
| Length | 20% | 3-5 tools is ideal |
| Success Rate | 25% | Successful patterns score higher |
| Recency | 15% | Recent patterns are prioritized |
Example Patterns
Grep → Read → Edit # Search, read context, make changes Glob → Read → Write # Find files, read, create new file Read → Edit → Bash # Read file, edit, run tests
Dynamic Skill Loading
Unlike standard Claude Code skills (loaded at session start), auto-generated skills can be loaded mid-session using a registry system.
How It Works
- •A lightweight registry indexes all skills (~metadata only)
- •Scripts retrieve and format skill content on demand
- •Output uses clear delimiters that signal active instructions:
====================================================================== SKILL LOADED: <name> Confidence: <score> Allowed tools: <tools> ====================================================================== <skill instructions> ====================================================================== END OF SKILL - INSTRUCTIONS ARE NOW ACTIVE ======================================================================
Proactive Discovery
Claude can automatically discover relevant skills using the skill-discovery skill:
- •User requests a multi-step task
- •Claude searches for matching skills
- •If found, Claude asks: "Would you like me to load this skill?"
- •User approves → skill is loaded and followed
CLI Commands
auto-skill discover # Discover skill patterns auto-skill search "query" # Search skills (FTS5) auto-skill stats # Show adoption statistics auto-skill graduate # Manage skill graduation auto-skill agents list # List known agents auto-skill agents detect # Detect installed agents
Execution Contexts
Generated skills automatically get appropriate execution settings:
| Pattern Type | Context | Agent | Why |
|---|---|---|---|
Grep → Read | Inline | Explore | Read-only, safe |
Read → Edit → Bash | Fork | general-purpose | Has side effects |
Inline: Runs in current conversation context.
Fork (context: fork): Runs in isolated subagent. Use for:
- •Tasks with side effects (deployments, builds)
- •Workflows that shouldn't pollute conversation history
- •Long-running operations
Tool Restrictions
Generated skills include allowed-tools based on the pattern:
allowed-tools: Grep, Read, Edit
This prevents scope creep and ensures predictable behavior.
Generated Skills
Auto-generated skills are saved to:
~/.claude/skills/auto/<skill-name>/SKILL.md
Each skill includes:
- •YAML frontmatter with metadata
- •
auto-generated: trueflag - •
context: forkif appropriate - •
allowed-toolsrestrictions - •Confidence score and source sessions
- •Procedural steps derived from the pattern
Configuration
Detection thresholds (in ~/.claude/auto-skill.local.md):
--- detection: min_occurrences: 3 # Minimum pattern repetitions min_sequence_length: 2 # Shortest pattern max_sequence_length: 10 # Longest pattern lookback_days: 7 # Analysis window min_confidence: 0.7 # Suggestion threshold ---
Data Storage
| Data | Location |
|---|---|
| Events | ~/.claude/auto-skill/events.db |
| Skills | ~/.claude/skills/auto/ |
| Tracking | ~/.claude/auto-skill/skills_tracking.db |
Privacy
- •All data is stored locally
- •No data is sent to external services
- •Anonymous telemetry can be disabled via
AUTO_SKILL_NO_TELEMETRY=1orDO_NOT_TRACK=1
Troubleshooting
No patterns detected?
- •Need 3+ occurrences of the same sequence
- •Check the lookback period (default: 7 days)
- •Run
/auto-skill:statusto see event counts
Skill not loading?
- •Run
auto-skill discoverto refresh - •Check the skill exists in
~/.claude/skills/auto/
Hooks not working?
- •Verify plugin is installed correctly
- •Check
hooks/hooks.jsonconfiguration - •Ensure Node.js 18+ is available
Want to reset?
- •Delete
~/.claude/auto-skill/events.db - •Remove skills from
~/.claude/skills/auto/
