Claude Knowledge

Persistent project knowledge for Claude Code - Captures patterns, quirks, and decisions that survive session boundaries.

What This Does

Claude Knowledge builds a persistent understanding of your project by capturing:

• Patterns: Approaches that work well in this codebase
• Quirks: Project-specific gotchas and unusual behaviors
• Decisions: Architectural choices with their rationale

These insights persist across sessions and context compaction, so Claude remembers what it learned even in new conversations.

Installation

# Add the marketplace (one-time)
/plugin marketplace add 0xrdan/claude-plugins

# Install the plugin
/plugin install claude-knowledge

# Restart Claude Code to activate

Quick Start

1. Work on your project as usual
2. Run /learn to extract insights from the conversation
3. Run /knowledge to view accumulated learnings

That's it! Knowledge persists automatically to the knowledge/ directory.

Commands

Command	Description
/learn	Extract insights from current conversation
/learn --deep	Thorough analysis with forked context
/learn-on	Enable learning mode (reminder flag)
/learn-off	Disable learning mode
/knowledge	View knowledge base status
/learn-reset	Clear all knowledge (requires confirmation)

How It Works

When you run /learn, Claude analyzes the conversation looking for:

1. Successful approaches - "This pattern worked for auth in this project"
2. Unexpected behaviors - "This module behaves differently than expected"
3. Decisions made - "We chose X over Y because of Z"

Each insight is categorized and saved to:

• knowledge/learnings/patterns.md
• knowledge/learnings/quirks.md
• knowledge/learnings/decisions.md

Example Entry

## Quirk: Auth tokens require base64 padding
- **Discovered:** 2026-01-08
- **Location:** src/auth/tokenService.ts
- **Behavior:** JWT tokens use non-standard base64 without padding
- **Workaround:** Use the custom `decodeToken()` helper instead of atob()
- **Confidence:** high

Learning Mode

Enable learning mode as a reminder to extract insights:

/learn-on   # Enable - /knowledge will remind you to run /learn
/learn-off  # Disable

Note: In v0.1.0, learning mode is a reminder flag only. You must still run /learn manually.

Sharing Knowledge

By default, knowledge is gitignored. To share with your team:

1. Edit knowledge/.gitignore
2. Comment out or remove learnings/
3. Commit the knowledge files

Migration from claude-router

If you previously used claude-router's knowledge features:

1. Your existing knowledge/learnings/ files are compatible
2. Simply install claude-knowledge and use the same commands
3. Note: If both plugins are installed, use full command names like claude-knowledge:learn

Recommended: Use one plugin for knowledge management:

• claude-knowledge: If you want ONLY knowledge features
• claude-router: If you want routing + knowledge (integrated)

Version Roadmap

• v0.1.0 (current): Manual extraction only - /learn must be called explicitly
• v1.0.0 (future): Auto-trigger mechanism (hook-based or notification-based)
