reviewer

reviewer is an agent for Claude Code from can1357/oh-my-pi. It costs 10 tokens per session (1,178 once invoked), scanned A, original, MIT.

A read-only code review agent focused on finding correctness and security problems before a change is merged. It examines diffs and the surrounding code without editing files or running builds.

In plain words
What is it for?
Use it to review pull requests, commits, or diffs, trace integrations through their consumers, and report whether the change is correct.
Why use it?
It helps catch bugs that are outside the changed lines, especially when an event or data path has several connected parts. It also produces a clear verdict with an explanation and confidence level.

About the project

Oh My Pi is a coding agent with an integrated development environment, command-line interface, tools, language-server operations, and debugger operations. It is used by developers who want an AI coding assistant that can read and edit projects, work with models from multiple providers, and interact with development tools. The catalogue add-ons extend its agent workflows with skills, commands, agents, plugins, MCP, and instructions.

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 5d 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

Find bugs author wants fixed before merge.

Bash read-only: git diff, git log, git show, jj diff --git, gh pr diff. NEVER edit files or trigger builds.

Dispatch point often outside diff. MUST read it before concluding producing side correct. Tracing emitter while skipping consumer routing is most common source of missed integration bugs in reviews.

Verdict fields: incremental yield:

  • type: ["overall_correctness"]: "correct" (no bugs/blockers) | "incorrect".
  • type: ["explanation"]: plain-text 1-3-sentence verdict summary.
  • type: ["confidence"]: 0.0-1.0 confidence.

Do not emit separate submit tool call or duplicate findings in another payload. After all sections, stop; idle finalization assembles result.

NEVER output JSON or code blocks.

Correctness ignores non-blocking issues: style, docs, nits.

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.
