review-staged

review-staged is a skill for Claude Code, Codex from photostructure/coding-skills. It costs 51 tokens per session (764 once invoked), scanned A, original, MIT.

A workflow for checking the changes currently staged in Git, the version-control system used to track code, and then preparing a commit message in a common format.

In plain words
What is it for?
Use it to review `git diff --cached`, report problems in staged files, suggest safer commit grouping, and prepare a Conventional Commit.
Why use it?
It helps find verified bugs or improvements before changes are recorded in the project history. It also helps decide whether the changes should be split into separate commits.

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-staged 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 23d 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 — 73 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Review Git Staged Changes

Review the staged diff (git diff --cached) for potential issues and improvements, then prepare the commit. When the user supplies a proposed commit message, use it as context for the intended change, not as a correctness requirement.

User direction

A direct "commit" or "approved, commit" instruction authorizes the understood scope and takes precedence over this skill's review and approval defaults. Unless the user also requests review first, use stage to verify and commit that scope without starting or resuming a review or asking for approval again. This also applies after findings or a review verdict; a reviewer's recommendation does not overrule the user's commit instruction. When project instructions require review before every commit, a commit instruction for changes that review has not finished on since they last changed runs the review first, and only an explicit instruction to skip review skips it.

Run the review

Size the scope before reading it: git diff --cached --stat. Review all staged content as supplied. The size or coherence of a proposed commit does not affect the review verdict.

With the staged diff as the scope, read and follow ../review/references/single-pass.md.

After the findings, use the shared Commit notes section for optional message or grouping advice. If a split would improve reviewability or make later reverts safer, identify the files or hunks in each independently committable batch and give a complete Conventional Commit message for every batch. State the specific reason for the split; size alone is not enough. These notes never receive a priority and never change the verdict. If they are the only concerns, return Verdict: LAND and No issues found.

Post-review commit flow

If the verdict is DISCARD, explain why the change should not land and stop the review. A later user instruction to commit takes precedence as described in User direction.

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.
