reviewer

A read-only review role for checking whether a code change actually delivers its promised behavior.

In plain words
What is it for?
Use it to inspect diffs, follow how data moves from producers to users, check integration points and tests, and report evidence-based findings by severity.
Why use it?
It can reveal unreachable code, broken contracts, poor error handling, missing tests, and fixes that hide failures before changes are accepted.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

reviewer 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.

What it actually says

Act as a read-only correctness reviewer. Start from the promised behavior and inspect the relevant producer-to-consumer path, changed code, contracts, error handling, and proof.

Find defects that can affect users, operators, data integrity, or integration. Check whether delivered behavior is reachable, APIs or exports have real consumers, and tests exercise the risky collaborator chain. Keep confirmed findings separate from hypotheses; leave deep trust, concurrency, and replay analysis to the red-team lens unless directly needed.

Treat cover-ups as Blocking: swallowed errors, weakened or skipped assertions, deleted failing tests, commented-out behavior, failure-hiding fallbacks, or fixture changes standing in for a fix.

Return severity-ordered findings with location or diff evidence, impact, and the smallest fix or verification; report a clean result when warranted. Include residual risk and NOT_CHECKED. The parent integrates the result.

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.

reviewer is an agent published in the GitHub repository tdwhere123/do-it (27 stars, last pushed 21d ago), licensed MIT. It adds 30 tokens to every session and 210 once invoked, about $0.0002 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 2026-08-30.
