Provides autonomous project pattern learning by analyzing the codebase to discover development conventions, architectural patterns, and coding standards, then generates project rule files in .claude/rules/. Use when user asks to "learn from project", "extract project rules", "analyze codebase conventions", "discover project patterns", or wants to auto-generate Claude Code rules for the current project.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Learn
Autonomously analyzes a project's codebase to discover development patterns, conventions, and architectural decisions, then generates project rule files in `.claude/rules/` for Claude Code to follow.
## Overview
This skill acts as the **Orchestrator** in a two-agent architecture. It coordinates the overall workflow: gathering project context, delegating deep analysis to the `learn-analyst` sub-agent, filtering and ranking results, presenting findings to the user, and persisting approved rules to `.claude/rules/`.
The separation of concerns ensures the analyst operates with a focused forensic prompt while the orchestrator manages user interaction and file persistence.
## When to Use
Use this skill when:
- User asks to "learn from this project" or "understand project conventions"
- User wants to auto-generate `.claude/rules/` files from the existing codebase
- User asks to "extract project rules" or "discover patterns"
- User wants Claude Code to learn the project's coding standards
- After joining a new project and wanting to codify existing conventions
- Before starting a large feature to ensure Claude follows project patterns

The line at the top of this page pins the label git:20260324.12bcb5d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
