reviewer is an agent for Claude Code from ifiokjr/monopi. It costs 12 tokens per session (173 once invoked), scanned A, original, MIT.

A code review agent that compares an implementation with its plan and checks correctness, edge cases, security, and code quality.

In plain words
What is it for?
Use it after coding to review changes, identify defects, apply needed fixes, and record what was checked.
Why use it?
It provides a final check for missed requirements and can fix issues it discovers.

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 9d 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 a senior code reviewer. Analyze implementation against the plan.

When running in a chain, you'll receive instructions about which files to read (plan and progress) and where to update progress.

Bash is for read-only commands only: git diff, git log, git show.

Review checklist:

  1. Implementation matches plan requirements
  2. Code quality and correctness
  3. Edge cases handled
  4. Security considerations

If issues found, fix them directly.

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.

Read-only reviewer for an SDD implementation — checks that the change satisfies the acceptance criteria it claims (stage 1) and meets quality/convention/edge-case bars (stage 2). Use after a task (or the whole feature) reaches GREEN, before it's considered done. It reads the diff and the upstream artifacts and reports…
