# radin: Set Up Companion-Tool Hooks `install.sh` installs the companion tool *binaries* globally (rtk, code-review-graph, caveman). It wires up no hook or MCP config. This skill does that wiring for code-review-graph, through radin's own script. ## Scope Only `code-review-graph` needs this step today. `caveman` is a Claude Code plugin, so its hooks register globally at plugin-install time and there is nothing to do. `rtk` is a CLI with no hook or MCP wiring. If radin later adds another companion tool that needs wiring, extend this skill and `lib/radin-crg-hooks.sh` instead of writing a new one. **Never run `code-review-graph install`.** Upstream's installer replaces the whole `hooks` key in settings.json, destroying any hooks the user already has. `RADIN_CLI crg-hooks` replicates its three writes merge-only, and skips any entry the target already defines — an existing definition, whatever its shape, is never redefined. ## Steps 1. Confirm the user is in the repo they want wired: run `git rev-parse --show-toplevel` and show the path. If it does not look right, ask. 2. Ask for explicit y/n confirmation, naming the three writes: "This adds a code-review-graph section to `~/.claude/CLAUDE.md`, two hooks (graph update on edits, graph status on session start) to `~/.claude/settings.json`, and an MCP server entry to `.mcp.json` in `<repo path>`. Anything already defined is left alone. Proceed?" 3. On yes: ```bash RADIN_CLI crg-hooks all ``` 4. On no:
