phx:init
Plugin Initialization
Install the Elixir/Phoenix plugin's behavioral instructions into the project's CLAUDE.md.
Usage
/phx:init # First-time installation
/phx:init --update # Update existing installation with latest rules
Iron Laws
- NEVER overwrite content outside plugin markers — User-written CLAUDE.md rules must be preserved verbatim
- Always detect stack before generating — Never assume Phoenix/Ecto versions
- Always validate after installation — Verify markers present and stack correct
