review-loop

A repeatable loop in which a build agent submits its work to a separate, read-only AI reviewer, receives structured findings, fixes problems, and submits the work again until it passes or reaches a limit.

In plain words
What is it for?
Use it to review commits or a whole phase of changes, manage pass or fail findings, apply review fixes, and enforce review limits and commit strategies.
Why use it?
It makes peer review consistent across build and planning work while recording decisions, isolating the reviewer, and stopping endless review cycles.

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

review-loop 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 yesterday.

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.

Review Loop Protocol

Agent-driven peer review loop for Build and Plan phases. The Build agent drives the loop; the reviewer is a separate, read-only LLM.

Loop Architecture

The review loop is agent-driven: the Build agent calls /review-submit, which invokes review-round-runner.sh as a synchronous subprocess. The runner executes one round and returns. The agent reads the result and decides the next action. There is no long-running orchestrator.

Driver-as-submitter mode: under the auto-build loop (auto-build-loop.md), scripts/auto-build-loop.sh plays the /review-submit role — it initializes .cct/review/state.json, invokes the runner with CCT_REVIEW_BASE_REF=<phase-base> so the whole multi-commit phase diff is reviewed (the default remains HEAD~1), commits review fixes itself, and injects commit_ref into fixed dispositions. The runner's contract (exit codes, file formats, breakers, sandbox) is unchanged.

Agent completes work → /review-submit → review-round-runner.sh (one round)
                                              ↓
                         EXIT 0 (PASS) → loop-summary.json → /phase-complete
                         EXIT 1 (FAIL) → findings-round-N.json → agent fixes → /review-submit
                         EXIT 2 (BREAKER) → breaker-tripped.json → agent stops → /review-decide

File Contract

All review-loop artifacts live under .cct/review/ during the active loop.

File Written By Purpose
state.json /review-submit (init), runner (update) Loop state: round, attempt, findings, breaker counters
findings-round-N.json Runner Structured findings for round N
resolution-round-N.json Build agent Builder's response to each finding
breaker-tripped.json Runner Breaker context, awaiting /review-decide
decision.json /review-decide Human's decision: approve, reject, or retry
loop-summary.json Runner (PASS) or agent (bypass) Final record of all rounds

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.

review-loop is a cursor rule published in the GitHub repository gosha70/code-copilot-team (6 stars, last pushed 2d ago), licensed MIT. It adds 26 tokens to every session and 1,580 once invoked, about $0.0001 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.
