review

review is a skill for Claude Code, Codex from brsbl/ottonomous. It costs 83 tokens per session (1,369 once invoked), scanned A, original, MIT.

A code-review workflow that examines a supplied diff, branch, file set, or pull request for concrete bugs and ranks findings by priority. A diff is the set of changes between two versions of code.

In plain words
What is it for?
Use it to review current or specified code changes, identify prioritised bugs, or apply caller-supplied findings in fix mode.
Why use it?
It gives review findings a defined scope and priority, then uses additional reviewers to check whether reported problems are real.

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 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 — 168 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Input: $ARGUMENTS

Review the caller's target or implement fixes from caller-supplied findings. Return results inline unless the caller provides an output destination.

Resolve the invocation

Identify:

  • Working location: repository or worktree to inspect
  • Target: explicit diff command, refs/range, pull request, file set, staged changes, or branch changes
  • Mode: review or fix
  • Output destination: optional caller-selected location
  • Fix selection: all findings, P0 only, or P0-P1

An explicit caller target always wins. When invoked without a target in a Git repository, review the current branch against its merge base with the default branch. staged means git diff --cached. State the exact scope and command used so the review is reproducible.

Do not invent a review registry, fixed plan path, or hidden persistence. In fix mode, use findings supplied inline, by exact reference, or from the current conversation. If none are available, ask the caller for them.

Review mode

1. Inspect and categorize the change

Read the complete diff, list changed and untracked files in scope, and inspect the full source context needed to understand each change.

Assign architectural changes to the architect-reviewer persona in $SKILL_DIR/agents/architect-reviewer.md:

  • APIs, schemas, migrations, services, dependency boundaries, configuration, directory structure, and public contracts

Assign implementation changes to the senior-code-reviewer persona in $SKILL_DIR/agents/senior-code-reviewer.md:

  • UI, business logic, bug fixes, refactors, tests, and utilities

Assign a file to both when both lenses materially apply.

2. Delegate independent review

Scale to the change rather than a fixed ceremony:

  • Small, cohesive diff: one reviewer with the appropriate persona
  • Several independent components: one reviewer per meaningful component
  • Large cross-cutting diff: multiple reviewers with explicit, non-overlapping scopes

Run independent scopes in parallel when the runtime supports it. Give every reviewer:

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.
