# 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 1. **NEVER overwrite content outside plugin markers** — User-written CLAUDE.md rules must be preserved verbatim 2. **Always detect stack before generating** — Never assume Phoenix/Ecto versions 3. **Always validate after installation** — Verify markers present and stack correct ## Workflow ### Step 1: Check Existing CLAUDE.md Use Glob to check if `CLAUDE.md` exists. Then use Grep to check for existing `ELIXIR-PHOENIX-PLUGIN:START` marker in `CLAUDE.md`. ### Step 2: Detect Project Stack Scan the project to customize the injected instructions: Read `mix.exs` and use Grep to extract: - Phoenix version: search for `phoenix.*"~>` in `mix.exs` - Ecto version: search for `ecto.*"~>` in `mix.exs` - Oban: search for `"oban"` and `"oban_pro"` in `mix.exs` - Frameworks: search for `"ash"`, `"surface"` in `mix.exs` - Tidewave: search for `"tidewave"` in `mix.exs` - Project size: use Glob to count `lib/**/*.ex` files ### Step 3: Handle Installation Modes **Mode A: Fresh Install** (no CLAUDE.md or no markers) 1. Create/append to CLAUDE.md 2. Insert full behavioral instructions between markers 3. Include only relevant sections based on detected stack **Mode B: Update** (`--update` flag or markers exist) 1.
