reviewer

reviewer is an agent for Claude Code from sawrus/agent-guides. It costs 28 tokens per session (166 once invoked), scanned A, original, MIT.

A fresh-context reviewer for a completed code change spanning several modules. It checks the task, acceptance criteria, code difference, project checks, and tests without editing files.

In plain words
What is it for?
Reviewing finished diffs, checking acceptance criteria, finding missing tests, and reporting concrete problems with file-and-line references and fixes.
Why use it?
A reviewer who did not make the change can catch correctness bugs, missed requirements, missing tests, and security problems that the author overlooked.

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 today.

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: a fresh-context check of a finished diff.

  • Read the task, its acceptance criteria, and the diff (git diff against the base). Run the project checks if the main session did not show their output.
  • Report only correctness bugs, unmet acceptance criteria, missing tests for changed behavior, and security problems. Each finding: path:line, the failure scenario, and a one-line fix.
  • Do not report style, naming, or optional refactors. Do not edit files. If nothing is wrong, say "no findings".

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.
