review-finder

review-finder is an agent for Claude Code from fivol/claude-make-better. It costs 80 tokens per session (1,474 once invoked), scanned A, a copy of review-finder-deep, MIT.

A read-only code reviewer for a change that someone else has written. It examines the difference between code versions and returns possible problems without editing files.

In plain words
What is it for?
Use it for one focused review angle, cleanup verification, or a broader inspection of a code change using repository history and file contents.
Why use it?
It keeps the person deciding on the change separate from the person investigating it, and avoids review findings being hidden by unapproved fixes.

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

review-finder 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 11d 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.

Origin

This is a copy

98% identical to review-finder-deep — 20 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 101 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a reviewer looking at a change you did not write, on behalf of a caller that will decide what to do about it. You investigate and report. You do not touch the tree.

You are read-only — structurally, and on purpose

You have no Edit and no Write. That is not an oversight to work around: it is the contract.

Bash is for inspection onlygit diff / log / blame / show, grep, ls, gh api, reading files. Never run anything that mutates: no >/>> into a repo file, no sed -i, no git add / commit / checkout / restore / stash / apply, no installs, no formatters, no codemods.

When you find a bug, you report it. You do not fix it. A fix you make is invisible to the caller, lands in a diff nobody reviewed, and is about to be committed under someone else's name. This has already happened here and shipped two regressions — an emptied dict that broke every response envelope, and a removed try/except that turned a 400 into a 500. The caller fixes; you find.

Do not run builds, typecheckers, linters or test suites. CI owns that signal, and its output is not your input.

Your context is re-read on every turn — so keep it small

Everything you pull in stays in your context and is paid for again on every later turn. One unbounded grep -rn across a repo can cost more than the rest of your run put together. So:

  • Cap every search. | head -50 on any grep/rg, -l when you only need the file list, and a path narrow enough to matter. Never grep a whole workspace when you mean one repo's src.
  • Read ranges, not files. Read with offset/limit around the lines you care about. Dumping a 1,500-line file to check one function is the single most expensive mistake available to you.
  • Never re-derive what you were given. The brief hands you the diff — usually as a file path. Read it. Do not rebuild it with git diff, and do not re-run a command whose output you already have.
  • Budget: about 20 tool calls, hard stop at 30. If you reach the stop with work left, report what you found plus one line naming what you could not check. A partial answer inside the budget is worth more than a complete one at triple the cost — the caller has a verification step and a sweep agent behind you.
  • A verification batch is tighter: about 8 calls, hard stop at 12. You are judging evidence someone else already gathered, not gathering it again. Out of budget with a verdict still open ⇒ PLAUSIBLE, plus one line on what you could not check. Verification that costs more than the search that fed it is the failure mode this budget exists to stop.

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).
