helixir: Command for Claude Code

/review — Code Review on Current Changes

Invokes the code-reviewer agent on the uncommitted and/or branched changes in the current working tree. Use this as a first-pass quality gate before you open a PR.

Arguments

• $ARGUMENTS (optional) — diff target. Defaults to main. Examples:
  • /review → diff against main
  • /review staging → diff against staging
  • /review HEAD~3 → diff against three commits back
  • /review --staged → only staged changes

Preflight

1. Read .rea/policy.yaml — confirm autonomy is at least L1 (review is read-only, so L0 also permitted)
2. Check .rea/HALT — if present, stop and report FROZEN
3. Verify you are inside a git repo: git rev-parse --show-toplevel

Step 1 — Gather the diff

Resolve the diff target:

• If $ARGUMENTS is empty → use main
• If $ARGUMENTS starts with --staged → use git diff --staged
• Otherwise → use git diff $ARGUMENTS...HEAD

Run in parallel:

git diff <target>...HEAD
git log <target>..HEAD --oneline
git status --short

If the diff is empty, stop and report: "No changes to review against <target>."

Step 2 — Delegate to code-reviewer

Invoke the code-reviewer agent with:

• Tier: standard (default). For diffs over 500 lines or cross-module changes, escalate to senior.
• Context: the full diff, the commit log, and the current branch name
• Project config: pass paths to package.json, tsconfig.json, and .rea/policy.yaml so the reviewer can adapt to the project's standards

Prompt shape for the delegation:

Review the following git diff at tier <standard|senior>. Produce structured findings: each finding has file, line, severity (high/medium/low), issue, and suggestion_code when applicable. Output JSON array. Empty array if no findings. Diff follows.

Step 3 — Summarize

Print a clean summary:

/review — <branch> vs <target>
Files changed: <N>
Findings: <total> (<high> high, <medium> medium, <low> low)

<grouped findings by severity, most severe first>
