review-code

review-code is a skill for Claude Code from gtrabanco/agentic-workflow. It costs 63 tokens per session (730 once invoked), scanned A, original, MIT.

An internal code-review step that checks changed code for correctness, error handling, duplication, unused code, unnecessary abstractions, and project conventions.

In plain words
What is it for?
Use it as part of a change review to inspect logic, failure paths, dependencies, naming, and simplification opportunities.
Why use it?
It helps reveal defects and needless complexity before a change is accepted. The review reports findings but does not edit the code.

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-code 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 26d 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 — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Review Code (internal)

Composed by review-change / product-audit within their conversation — on any agent, follow this file inline as the routed step. Findings only; never edits, never refactors.

Scope

The diff or path/glob the caller passes; default the current change vs the default branch. State the scope at the top of the returned table.

Checklist (evaluate EVERY item — none is optional; n/a must be stated)

✓ No logic errors on the changed paths (trace each modified function's inputs → outputs, including boundary values) ✓ Every error path is handled — no swallowed exceptions, no empty catch, no silently-ignored return codes ✓ No duplicated logic (a changed block does not re-implement an existing helper — cite the existing one if it does) ✓ No dead code introduced (unused functions, params, imports, unreachable branches) ✓ No leftover TODO/FIXME/HACK markers in the diff ✓ Naming and file conventions match the project's docs (read them first; cite the convention violated) ✓ No new abstraction beyond what the SPEC requires (an interface/base class with one implementation is a finding) ✓ No new dependency not justified in the SPEC ✓ Simplification: any changed block that can lose lines without losing behavior (cite before/after) ✓ Reference trace: every changed symbol/API got a reference search — un-updated callers are findings ✓ Edge cases the SPEC's dev scenarios name are actually handled in code, not just in tests

Materiality bar

Report a row only when a competent user's outcome changes or a rule the project explicitly declares is violated — cite the rule it violates beside the evidence. Not findings: comment/punctuation typos, formatting-only drift, style preference with no cited rule, hypothetical robustness beyond the SPEC's named scenarios. An empty table with Decision: PASS is the expected result for a well-formed change — never pad the table.

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.
