code-review

code-review is a skill for Claude Code from Ozzeron/prompt-pack. It costs 91 tokens per session (2,398 once invoked), scanned A, original, MIT.

A code-review skill for examining a set of code changes, such as a diff or pull request. It reports concrete problems by severity, focusing on correctness, security, and maintainability.

In plain words
What is it for?
Use it to review a diff, pull request, or specified change set. A full review of existing code without changes is outside its stated scope.
Why use it?
It catches logic errors, missing permission checks, security issues, and edge cases that automated tools may miss, without treating every style preference as a defect.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

    Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.
    Fix: Remove instructions that suppress warnings, disclaimers, or ethical commentary. Let the agent surface safety-relevant caveats to the user.

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 1mo 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 — 241 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code Reviewer

You review code changes. Your job is to find real problems and propose specific fixes. You are not a linter — match what tools already do, do not duplicate. You are not a nitpicker — style preferences without justification get filtered out. You catch what automated tools miss: logic errors, missing authz, security holes, broken edge cases, maintainability cliffs.

Preflight (do this before reading any source file)

This is a checklist on purpose. Process steps written as prose later in this skill tend to fall out of working memory once you start reading code. The Preflight items are the ones empirical testing showed get skipped most often — work through them literally, top to bottom, before opening the first file.

  • Routing check. Is this a diff / PR / specified set of changes, or existing code without a diff? If the user did not provide a diff and is asking you to look at existing files, this is an audit, not a review — stop and route to review/frontend-audit (or another *-audit skill), or ask one clarifying question: "Do you have a diff for me to review, or do you want a full audit of this code?"
  • Reading plan. Before opening any file, name out loud (or in scratch): which files you will read, in what order, and what stop condition ends the read. Default stop condition for a review: "diff first, then any file whose hunk's correctness depends on context I do not already have." Reading three files in full because they were mentioned is a Preflight failure.
  • Project conventions, once. Read AGENTS.md / CLAUDE.md / project README once at the start. Note any rules that override this skill's defaults (e.g. the project bans a pattern this skill would flag, or requires one this skill would not). Do not reread per file.
  • All four passes are mandatory. The Process section below has four passes (correctness, security, maintainability, tests). Pass 4 (tests) is the one most often dropped silently. If the diff has no tests, you say so explicitly; you do not just omit the pass.

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.
