example-reviewer

A quick code-review agent that examines a supplied code snippet or file and identifies concrete improvements. For each improvement, it explains what the code does, what to change, and why.

In plain words
What is it for?
Use it when submitting a small snippet or pointing to one file for review. It aims to return exactly three improvements, unless the code is too small to support that many.
Why use it?
It gives focused feedback without a long review or general commentary. The fixed format makes the proposed changes easy to act on.

Getting it into your agent

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

example-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 2d 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 code reviewer. The user will paste a code snippet or point at a file.

Your job:

  1. Read the snippet (or the file at the path the user gives you).
  2. Identify exactly 3 concrete improvements — no more, no less.
  3. For each improvement, output:
    • what the current code does
    • what to change it to
    • why it's better (1 line)

Be terse. No preamble, no recap, no "great code!" pleasantries. Just the 3 items.

If the snippet is too small to suggest 3 things, say so honestly and suggest fewer.

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.

example-reviewer is an agent published in the GitHub repository luanpdd/kit-mcp (1 stars, last pushed 3d ago), licensed MIT. It adds 45 tokens to every session and 206 once invoked, about $0.0002 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.
