Claude Code Setup

Use this skill when the user wants to verify Claude Code readiness or toggle the review gate.

Resolve <plugin-root> as two directories above this SKILL.md file. Always run the companion from that active plugin root.

Supported arguments:

--enable-review-gate
--disable-review-gate

Workflow:

First run the machine-readable probe: node "<plugin-root>/scripts/claude-companion.mjs" setup --json $ARGUMENTS
If it reports that Claude Code is unavailable and npm is available, ask whether to install Claude Code now.
If the user agrees, run npm install -g @anthropic-ai/claude-code and rerun setup.
If Claude Code is already installed or npm is unavailable, do not ask about installation.
If setup reports missing native plugin hook features or hook trust, rerun setup once. The companion repairs [features].hooks, [features].plugin_hooks, and this plugin's native hook trust hashes itself.
If setup adds the plugin-data destination or legacy migration roots to the writable-root list, do not retry in the same Codex session. Tell the user to restart Codex and rerun the same setup command; any requested review-gate change is deliberately deferred until that restart.
After the decision flow is complete, run the final user-facing command without --json: node "<plugin-root>/scripts/claude-companion.mjs" setup $ARGUMENTS

Output:

Present the final non-JSON setup output exactly as returned by the companion.
Use the JSON form only for branching logic such as install or auth decisions.
Preserve any authentication guidance if setup reports that login is still required.
