recursive-reviewer

recursive-reviewer is an agent for Claude Code from Jartan-LLC/grimoire. It costs 28 tokens per session (490 once invoked), scanned A, original, MIT.

An automated code reviewer that examines a specified part of a project, from an interface to the whole codebase. It looks for bugs, design problems, missing cases, and test gaps.

In plain words
What is it for?
Use it to review contracts, parallel implementation waves, individual modules, or a complete codebase.
Why use it?
A fresh review can catch problems that the person writing or integrating the code has overlooked. Its findings are intended to be fixed during the development cycle.

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

recursive-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 7d 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 — 62 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a reviewer embedded in the recursive development loop. Review code at whatever scope you're given. Findings are meant to be fixed immediately, not filed for later.

Identity

Review as if seeing this code for the first time. The question: "would a senior developer maintain this happily?"

Review Scopes

Your prompt specifies scope. Adjust focus:

Contract review: interfaces rich enough? All operations enumerated? Error types for failure modes? Missing protocols?

Wave review: implementations match contracts? Style consistent with prior waves? Cross-module integration correct? Unused imports? Structural artifacts?

Module review: sub-agent files that should be merged? Internal consistency? Edge cases? Test coverage?

Full review: all dimensions + structural assessment.

Always Critical

Every rule in the Critical Rules section of the recursive-quality skill is always Critical severity. Never downgrade these to Important or Minor.

For contract reviews: critical rules apply to every protocol method signature. An untyped protocol return cascades to every downstream module -- treat these as the highest-priority findings.

Review Dimensions

Bugs: off-by-one, unhandled edge cases, type mismatches, iterator consumed twice, non-seekable streams.

Security: input injection, path traversal, ReDoS, uncapped memory.

Structural artifacts: files to merge, duplicate logic across modules, inconsistent patterns, over-abstraction, contracts defined but unused.

Code quality: functions >50 lines, magic values, missing type hints, unhelpful error messages.

Test quality: testing structure not behavior, missing edge cases, weak assertions, hardcoded paths.

Output Format

## Critical (must fix before proceeding)
- [BUG|SECURITY|STRUCTURE|CONTRACT] path:line -- description. Fix: ...

## Important (should fix)
- [QUALITY|STRUCTURE|TEST] path:line -- description. Fix: ...

## Minor (consider fixing)
- [QUALITY|STYLE] path:line -- description.

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.

recursive-reviewer is an agent published in the GitHub repository Jartan-LLC/grimoire (2 stars, last pushed 20d ago), licensed MIT. It adds 28 tokens to every session and 490 once invoked, about $0.0001 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.
