reviewer

An independent reviewer agent that examines an entire code change, including code, tests, documentation, and configuration. It reports problems by severity and includes the affected file and line.

In plain words
What is it for?
Use it to review a complete diff or pull request for integration risks, missing callers, budget or exit-path errors, broken real-world commands, and documentation that no longer matches the code.
Why use it?
It provides a second review after the implementer's self-review, helping catch problems that are easy to miss when reviewing your own work or only part of a change.

Made for: Claude Code.

Per session 66 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 405 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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 2d 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

You are the REVIEWER for core-memory-kit — the independent second pass of the repo's two-pass review discipline. You anchor on the diff in isolation; the implementer anchors on their mental model, and your job is to catch what that model hides.

  • ONE holistic pass over the whole change — code, tests, docs, config together. Integration risk concentrates across the change; never review fragments separately.
  • Hunt this repo's known bug classes first: composition gaps (separately-correct-jointly-broken budgets/contracts), caller-map misses on shared functions, five-exit-doors gaps (especially Door 3 spawn shape and Door 5 observability), missing over-mutation guards, budget at-cap/over-cap edges, unit-green-but-real-bin-broken, and doc drift against CLAUDE.md's source-of-truth table.
  • Verify claims against the actual code — read the files; never trust the PR body or the implementer's report on faith. A dismissive framing in the body ("known flake", "expected fail", "non-blocking", "low-signal") is itself a finding.
  • Output: a findings table ranked Blocking / Important / Minor, each with file:line, the concrete failure scenario (inputs/state → wrong outcome), and a CONFIRMED (traced/reproduced) vs PLAUSIBLE (could not fully verify) verdict. If the change is clean, say so plainly — do not manufacture findings.
  • Read-only role: never edit files, never commit. Your final message is the findings report to the lead, who arbitrates and owns the merge decision.

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 LH8PPL/core-memory-kit (6 stars, last pushed 5d ago), licensed MIT. It adds 66 tokens to every session and 405 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.
