review

review is a skill for Claude Code from angad-kandhari/deliberate. It costs 57 tokens per session (1,454 once invoked), scanned A, original, Apache-2.0.

A code-review guide for coding agents. It covers understanding the intended change, checking correctness from broad issues down to details, and reviewing tests as part of the code.

In plain words
What is it for?
Use it when reviewing a pull request, checking an existing codebase, or reviewing your own changes before submitting them.
Why use it?
It reduces shallow reviews that approve incorrect changes or focus on minor style issues while missing serious problems.

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 10d 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.

Review

Code review skill for LLM coding agents. Load this when reviewing a PR, reviewing your own diff before handing it back, or auditing code someone else wrote.

Where deliberate keeps writing honest, this skill keeps reviewing honest. Counters rubber-stamp "LGTM" reviews, nitpick-only reviews, and missing the forest for the trees.


1. Read the Intent First, Code Second

Know what the change is trying to do before judging how it does it.

  • Read the PR description, linked ticket, or commit message before the diff.
  • If you can't state the goal in one sentence, ask - don't review blind.
  • A clean implementation of the wrong thing is worse than a messy implementation of the right thing.

If intent is missing:

"I can review the code, but I need the goal first. What problem is this solving?"

Test: Can I say in one sentence what this change is for?


2. Review in Layers, Top-Down

Don't start with nits. Start with correctness.

Review in this order, and stop at the first layer that has a blocking issue:

  1. Does it solve the stated problem? If not, nothing else matters.
  2. Is the approach sound? Right abstraction, right layer, right trade-offs.
  3. Is it correct? Edge cases, error paths, concurrency, data integrity.
  4. Is it safe? Auth, input validation, injection, secrets, PII.
  5. Is it maintainable? Naming, structure, testability.
  6. Is it consistent? Matches surrounding code style and conventions.
  7. Nits. Formatting, spelling, preferences.

Leaving an architectural concern to the end while drowning the author in nits is a failure mode. Start at the top.

Test: Are my highest-priority comments about the highest-priority concerns?


3. Distinguish Blocking From Non-Blocking

Label every comment so the author knows what to act on.

Use clear prefixes:

  • blocking: must be addressed before merge.
  • question: genuine ask, not a veiled critique.
  • suggestion: take it or leave it.
  • nit: cosmetic, optional.
  • praise: noting what's good. Worth doing.

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.
