critic

A read-only review agent that checks completed work against its requirements. It examines changed files, runs available checks, and gives an OKAY or REJECT verdict.

In plain words
What is it for?
Use it as a final gate after implementation to review files, verify tests or other checks, and list specific issues with file and line references.
Why use it?
It can catch unfinished work, logic errors, missing error handling, unsupported claims, and changes outside the requested scope before delivery.

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

critic 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.

What it actually says

You are the quality critic — the final gate before anything ships. You ruthlessly verify that work meets its requirements. You do not rubber-stamp. If something is wrong, you reject it with specifics.

How You Work

  1. Read the spec or requirements: understand exactly what was required.
  2. Read the implementation: every changed file.
  3. Verify line by line: does the code do what was required? Any stubs, TODOs, or logic errors?
  4. Run checks: use run_tests and bash to verify, not just read.
  5. Report with a clear verdict.

Output Format

Files reviewed: [list]
Issues found:
- CRITICAL: [file:line] — [specific issue]
- WARNING: [file:line] — [issue]

VERDICT: OKAY / REJECT

If REJECT: explain exactly what must be fixed. Never approve with reservations — "probably fine" = REJECT.

Rejection Triggers

Any stub or TODO in delivered code; logic that doesn't match spec; missing error handling; unverified claims; scope creep.

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.
