About this capability

Review source files changed during a phase for bugs, security issues, and code quality problems

What this skill tells your AI

The instructions your AI receives, as published by open-gsd/gsd-core in skills/gsd-code-review/SKILL.md and read by ahel’s review.

Spawns the gsd-code-reviewer agent to analyze code at the specified depth level. Produces REVIEW.md artifact in the phase directory with severity-classified findings.

Arguments:

  • Phase number (required) — which phase's changes to review (e.g., "2" or "02")
  • --depth=quick|standard|deep (optional) — review depth level, overrides workflow.code_review_depth config
    • quick: Pattern-matching only (~2 min)
    • standard: Per-file analysis with language-specific checks (~5-15 min, default)
    • deep: Cross-file analysis including import graphs and call chains (~15-30 min)
  • --files file1,file2,... (optional) — explicit comma-separated file list, skips SUMMARY/git scoping (highest precedence for scoping)
  • --fix (optional) — after review completes (or if REVIEW.md already exists), auto-apply fixes found. Spawns gsd-code-fixer agent. Accepts sub-flags:
    • --all — include Info findings in fix scope (default: Critical + Warning only)
    • --auto — enable fix + re-review iteration loop, capped at 3 iterations
  • Optional reviewer-lane flags (#4209) — any flag returned by gsd_run review-lane flags (the canonical reviewer-lane roster; e.g. --codex, --agy) requests that lane independently review the same already-resolved scope alongside the internal gsd-code-reviewer agent. Its findings are corroborating evidence only — gsd-code-reviewer alone verifies each claim against the actual source and writes REVIEW.md; there is exactly one REVIEW.md schema. No reviewer-lane flag (the default) reviews with only the internal agent, byte-for-byte unchanged from before #4209.

Output: {padded_phase}-REVIEW.md in phase directory + inline summary of findings

<execution_context> @~/.claude/gsd-core/workflows/code-review.md </execution_context>

Optional flags parsed from $ARGUMENTS:

  • --depth=VALUE — Depth override (quick|standard|deep). If provided, overrides workflow.code_review_depth config.
  • --files=file1,file2,... — Explicit file list override. Has highest precedence for file scoping per D-08. When provided, workflow skips SUMMARY.md extraction and git diff fallback entirely.

Context files (CLAUDE.md, SUMMARY.md, phase state) are resolved inside the workflow via gsd-tools query init.phase-op and delegated to agent via <required_reading> blocks.

Execute end-to-end.

The workflow (not this command) enforces these gates:

  • Phase validation (before config gate)
  • Config gate check (workflow.code_review)
  • File scoping (--files override > SUMMARY.md > git diff fallback)
  • Empty scope check (skip if no files)
  • Agent spawning (gsd-code-reviewer)
  • Result presentation (inline summary + next steps)
