review

review is a skill for Claude Code from joao-aires/agent-skills-public. It costs 45 tokens per session (499 once invoked), scanned A, original, MIT.

A code-review workflow for examining a pull request, branch, or current code change against its intended behavior and engineering standards. It reports concrete findings and missing evidence without changing the source by default.

In plain words
What is it for?
Use it to inspect the relevant diff, run suitable authorized checks, verify affected journeys, and report each issue with its severity, location, impact, and fix.
Why use it?
It helps catch correctness, scope, security, data, reliability, user-journey, and delivery problems before a change is accepted.

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 yesterday.

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

Read task guidance. Read deliver-reliable-changes for completion evidence and scope. Load the optional stack/domain guidance selected by task guidance only when relevant and available.

Establish and assess the review target

Pin target/base/head from the PR or current repository context; ask only if ambiguity changes the diff.

  • Use the agreed request/spec/ticket when present, without requiring a tracker or inventing requirements.
  • Follow the changed behavior from its caller to its result. Read enough surrounding code to understand existing callers, stored state and error handling, then check whether the new behavior agrees with them.
  • Examine consequential assumptions: which actor is trusted, which changes happen together, what a retry means, and which consumers may still use the previous behavior. Use relevant specialists to deepen concerns that the diff actually changes.
  • For affected UI use interface assessment expertise and interface-language expertise when installed; distinguish rendered/runtime evidence from static inspection.
  • Use usability research expertise only for relevant supplied observations or a requested research plan, not to fabricate validation.
  • Use code-review or security techniques only as supported by the client's invocation controls; review inline if delegation is unavailable.

Verify and report findings

Inspect existing checks and run appropriate authorized local tests when useful, including actual affected journeys. CI status alone does not establish that all tests passed.

For each finding, provide:

  • Severity and concrete location/scenario.
  • User or system impact.
  • An actionable fix.

Support a defect with a concrete path through the changed code and the condition that makes it fail. Explain why the result violates an accepted requirement or existing behavior. When the concern depends on an assumption you could not verify, state that assumption and the evidence needed to resolve it. Distinguish missing evidence from a proven defect. Leave source unchanged by default, apart from owned test/runtime artifacts. Posting comments, applying fixes, approving or merging requires the request or trusted job policy. A changed head invalidates earlier review/test conclusions.

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.

review is a skill published in the GitHub repository joao-aires/agent-skills-public (2 stars, last pushed yesterday), licensed MIT. It adds 45 tokens to every session and 499 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-15.
