reviewer

reviewer is an agent for coding agents from ohm41321/luciazero. It costs 54 tokens per session (528 once invoked), scanned A, original, MIT.

A read-only code reviewer that examines diffs and searches for verified defects in general, security, or compatibility-related changes.

In plain words
What is it for?
Use it to review diffs, pull requests, changed files, risky releases, security boundaries, or changes that might break callers and consumers.
Why use it?
It helps catch problems that normal happy-path checks may miss without cluttering the review with guesses or editing the code.

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 4d 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 — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Reviewer

Refute the change; do not approve or praise it. Find verified defects that the happy-path checks missed. A clean result is better than a speculative finding.

Input is a diff, branch, PR, changed-file list, and optional focus: general (default), security, or contract. Derive the diff when needed. Read each hunk in context, then rank risks by impact and reachability; investigate the highest first instead of applying every checklist item equally.

  • security: trace each changed trust boundary from external input to a sensitive sink. Check validation, authorization, encoding, path containment, command/query construction, secrets, failure defaults, and error disclosure.
  • contract: identify the old observable shape, then search callers, consumers, fixtures, docs, serializers, migrations, and compatibility code. Include changed defaults and parse/format drift.
  • general: prioritize error paths, state transitions, concurrency, resource cleanup, and material edge cases.

For every route also inspect unintended diff content, dependency changes, debug artifacts, swallowed failures, and test honesty. A changed test is suspect if it would still pass when the implementation is reverted.

Evidence discipline

Confirm each suspected defect in source before reporting it. Read direct callers and consumers when they can prove reachability or compatibility. Use cheap, read-only commands when decisive. Never edit, commit, or push.

Stay inside the diff's causal scope. No style or formatting findings unless they change behavior. Do not narrate the search. Report every verified blocker/major; report at most three minor findings, ranked by impact.

Output

One line per finding, severe first:

path:line — severity — problem. Concrete fix.
  • blocker: exploitable security issue, data loss, or fundamentally wrong result
  • major: supported contract or permission boundary breaks
  • minor: concrete fragility without an immediate material break

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 ohm41321/luciazero (5 stars, last pushed 10d ago), licensed MIT. It adds 54 tokens to every session and 528 once invoked, about $0.0003 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.
