code-review

A coordinated process for reviewing code changes with several specialized reviewers and a final combined report. It can include codebase research and, when needed, research into outside alternatives.

In plain words
What is it for?
Use it to review a pull request, compare your branch with the main branch, or inspect selected files and directories for risks and improvements.
Why use it?
It reduces the chance that important bugs, design issues, or context are missed during a code review.

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

code-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 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.

How it starts

The opening of the file, as written. The whole thing — 233 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code Review

Orchestrate a multi-agent code review pipeline: research the changes, optionally investigate external alternatives, dispatch parallel domain-specific reviewers, and synthesize everything into a structured report.

Input Collection

Prompt the user to select an input mode. Present these options clearly:

What would you like me to review?

  1. Current PR — review the open PR on this branch (description + diff)
  2. Diff to main — review all uncommitted and committed changes vs main
  3. Specific paths — review specific files, crates, or directories

Pick a number, or describe what you'd like reviewed.

Collecting the diff

Mode 1 — Current PR:

gh pr view --json title,body,number,baseRefName
gh pr diff

If no open PR exists, tell the user and suggest mode 2 instead.

Mode 2 — Diff to main:

git diff main...HEAD

Also include git log main..HEAD --oneline for commit context.

Mode 3 — Specific paths: Ask the user for paths. Read the specified files directly. No diff — review the code as-is.

Store the collected input (diff text, PR description, file contents) for use in subsequent phases.

Handling large diffs

If the diff exceeds ~2000 lines, save it to a temporary file (/tmp/code-review-diff.patch) and have agents read it via the Read tool rather than inlining it in their prompts. This prevents context overflow. Reference the file path in agent prompts instead of pasting the diff.

Phase 1: Research & Domain Mapping

Spawn an Agent (subagent_type: general-purpose) and include the full text of the research-codebase skill instructions in its prompt (read .claude/skills/research-codebase/SKILL.md first). Direct the agent to research the changes with this focus:

  • Map all changed files to their logical domains and crate boundaries
  • Identify which changes are Rust code vs non-Rust (CI, docs, config, TypeScript SDK, nix, etc.)
  • Understand the architectural context around each change — what traits, types, and modules are involved
  • Group changes into at most 4 logical domain groups, merging smaller related changes together
  • Flag any changes that warrant external web research:
    • New dependencies or crate additions
    • Unfamiliar architectural patterns
    • Potentially deprecated API usage
    • Cases where alternative approaches might exist

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.
