Coach

Self-improving learning system for Claude Code that detects friction signals and proposes rule updates.

🔌 Plugin Type: Feature Plugin

This is a Feature Plugin - it provides active automation via hooks and slash commands that run during your session, unlike Skill Plugins which only provide reference knowledge.

What makes it a Feature Plugin:

• Hooks that detect friction signals in real-time
• Slash commands for reviewing and approving changes
• Session analysis and cross-repo learning

Coach follows the Agent Skills specification and includes a skill component (SKILL.md), but extends it with automation features.

Supported Platforms:

• ✅ Claude Code (Anthropic)
• ✅ Other platforms supporting hooks and commands

Features

• Signal Detection: Automatically detects user corrections, tool failures, repeated instructions, and tone escalation
• Skill Update Suggestions: Detects when users supplement skills with additional guidance and proposes skill updates
• Outdated Tool Detection: Identifies deprecated tools and outdated dependencies from command output
• LLM-Assisted Generation: Uses Claude Haiku to generate specific, actionable learning candidates
• Transcript Analysis: Analyzes full session transcripts at session end for comprehensive learning
• Cross-Repo Learning: Tracks patterns across repositories and proposes promotion to global rules
• Proactive Scanning: /coach scan checks for outdated CLI tools and project dependencies
• Approval Workflow: All changes require explicit user approval

Installation

Install via Claude Code plugin marketplace:

/plugin marketplace add netresearch/claude-code-marketplace

Then install Coach from the plugin list. The plugin auto-configures itself on first use.

Slash Commands

Command	Description
/coach status	Show system status and statistics
/coach review	Show pending learning proposals
/coach approve <id>	Approve and apply a proposal
/coach reject <id>	Reject a proposal with reason
/coach edit <id>	Edit a proposal before approving
/coach promote <id>	Promote project rule to global
/coach scan	Scan for outdated tools and dependencies
/coach init	Initialize the coach system

How It Works

1. Hooks detect friction signals as you work:

   • UserPromptSubmit: Detects corrections and repetition in user messages
   • PostToolUse: Captures command failures with exit codes
   • Stop: Runs full aggregation at session end

2. Signals are stored in ~/.claude-coach/events.sqlite

3. Candidates are generated from patterns in signals

4. Review candidates with /coach review and approve/reject

5. Rules are added to your CLAUDE.md files

Configuration

The plugin auto-configures hooks. For manual configuration or customization, see hooks/hooks.json.

Stable Hook Paths

Coach automatically maintains stable hook paths that survive plugin version updates. Hooks run asynchronously for improved performance.

How it works:

1. On first hook execution, Coach auto-installs ~/.claude-coach/bin/coach-run launcher
2. Settings.json hooks are automatically upgraded to use the stable launcher with --async mode
3. The launcher dynamically resolves the current plugin version at runtime
4. Async mode spawns scripts in background - hooks return immediately without blocking Claude Code
5. Future plugin updates work seamlessly - no user action required

Manual recovery (if needed): If hooks break after an update, running /coach init will repair them.
