code-review-gate

code-review-gate is a skill for Claude Code, Codex from LuisFelipeMoro/Harness-devkit. It costs 89 tokens per session (582 once invoked), scanned A, original, MIT.

A gate that checks code made outside a complete development pipeline, then sends it to a Reviewer agent. It combines quality checks with a review of the changed files.

In plain words
What is it for?
Use it before pushing or signing off code to run the quality gate, review only the changed files, and receive a score and final PASS or BLOCK verdict.
Why use it?
It prevents ad-hoc code edits from being treated as finished when tests or security checks fail, or when the review finds a serious problem.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

code-review-gate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 22 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Every code change outside a pipeline must clear this gate before it counts as done. Gates must be green before the Reviewer runs, and a CRITICAL security finding always blocks.

Contract

  • Input: a working directory with changed files.
  • Output: a gate report (PASS/FAIL per gate), then a Reviewer score (1–10) with structured findings, then a verdict line.
  • Tool boundary: this skill reports and routes; it never auto-fixes failing gates or findings. The Reviewer sees only the changed files, never the full codebase.
  • Done when: Phase 3 prints a PASS verdict line, or a BLOCK with the specific finding to fix.

Steps

  1. Phase 1 — Quality Gates. Invoke the /quality-gate skill. If any gate fails, show the failing gate and its error output, stop, surface the fix, and wait for a re-run. Phase 2 begins after every gate is green.
  2. Phase 2 — Reviewer. Collect the changed files with the commands in references/diff-verdict-and-rules.md, then dispatch the Reviewer subagent — coding-pipeline:reviewer (or reviewer in a flat ~/.claude/agents install) — handing it the full content of each changed file, the one-line gate summary, and the original request verbatim (the Reviewer needs it to judge change discipline). The dispatched subagent already carries its Reviewer persona; do not read the agent file into the main context. It covers the Security Deep-Dive checklist, language-specific checks, the test-falsifiability check, and the change-discipline check (CD1–CD7) defined in that reference.
  3. Phase 3 — Verdict. Apply the verdict table in references/diff-verdict-and-rules.md: score ≥ 8.0 with no CRITICAL passes; any CRITICAL blocks; below 8.0 surfaces findings for a decision. After any fix, restart from Phase 1.

References

  • references/diff-verdict-and-rules.md — diff collection commands, Reviewer payload, falsifiability check, verdict table, and anti-patterns.
  • coding-pipeline/references/change-discipline.md — CD1–CD7 rows, severities, and worked ❌/✅ examples (single source of truth).

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

code-review-gate is a skill published in the GitHub repository LuisFelipeMoro/Harness-devkit (10 stars, last pushed 3d ago), licensed MIT. It adds 89 tokens to every session and 582 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
