📖 Grimoire — Updating the Knowledge Library

Manage and update CLAUDE.md files across all projects.

Activation

When this skill activates, output:

📖 Grimoire — Updating the knowledge library.

Then execute the protocol below.

Protocol

  1. Identify the target project — use config.json to find the CLAUDE.md path
  2. Read the current CLAUDE.md if it exists
  3. Determine what to update based on the session's work:
    • New API endpoints built
    • New database tables/migrations
    • New pages or components added
    • Architecture decisions made
    • Environment variables added
    • Dependencies installed
  4. Update the CLAUDE.md:
    • Keep existing content intact
    • Add new entries under the right headings
    • Don't duplicate existing entries
    • Use consistent formatting
  5. If no CLAUDE.md exists — create one with standard sections:
    • Project Overview, Tech Stack, Directory Structure, Key Files
    • API Endpoints, Database Schema, Environment Variables, Dev Commands

Inputs

  • Project name (maps to config.json entry)
  • What was built/changed this session

Outputs
