review-diff

A command that opens a Git diff in an interactive review interface. It lets you inspect and annotate changed lines before committing or requesting review.

In plain words
What is it for?
Use it to review staged, unstaged, or selected commit-range changes, approve them, or request changes with inline comments.
Why use it?
Reading a diff in a terminal can make it harder to discuss individual lines. Inline annotations keep comments attached to the exact code they concern.

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-diff 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 presenting a git diff for human review using the ai-review CLI.

Steps

  1. Get the diff you want to review. For staged changes use git diff --staged; for all uncommitted changes use git diff HEAD; for a specific range use git diff <base>..<head>. Note: Run git add -N . first to include untracked files in the diff. This records the intent to add the files, making them visible to git diff without fully staging them.
  2. Run the CLI, piping the diff to stdin:
    git diff HEAD | node ~/git/ai-review-plan/dist/cli.js diff --title "<short task-specific title>" --theme <dark|light>
    
    Use --theme light unless the user has expressed a preference for dark mode.
  3. Once the CLI launches, check its initial output (e.g. Opening http://localhost:<port>) and tell the user what port the review is active on. Wait for the CLI to exit. It blocks until the user submits their review.
  4. Check the exit code and stdout:
    • Exit 0 (Approved): The user approved the diff. Address any inline comments in code, then proceed.
    • Exit 1 (Changes Requested): The user requested changes. Do not commit or push. Show the user the comments from stdout, address them in code, and offer to run another review pass.
  5. The stdout always begins with ## Review: APPROVED or ## Review: CHANGES REQUESTED, followed by any comments as a numbered list. Read each comment carefully.

Notes

  • Always pass --title. Derive it from the branch name or the work being done (e.g. "Auth middleware changes", "Dark mode CSS") — never use a generic title like "Diff review".
  • Always pass --theme. Default to light; switch to dark if the user has indicated a preference.
  • If the diff is very large (hundreds of files), warn the user before opening and offer to scope it to specific paths: git diff HEAD -- src/.
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.
