atomic-review

atomic-review is a skill for Claude Code, Codex from damusix/atomic-claude. It costs 63 tokens per session (1,450 once invoked), scanned A, original, MIT.

A code-review format that records only concise, actionable findings, with each comment naming the location, problem, and fix. A pull request is a proposed code change awaiting review.

In plain words
What is it for?
Use it when reviewing a pull request, diff, or other code change, especially when a changed public function or interface may affect its callers.
Why use it?
It reduces lengthy or low-value review discussion while preserving issues that could affect correctness, safety, performance, or maintainability.

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

atomic-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 7d 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 — 111 lines — stays where its author put it; the contents beside it link to each section on GitHub.

  • "review this PR", "code review", "review the diff", "check this PR"
  • "review this change", "review my changes"
  • Reviewing pull requests or diffs

Write code review comments terse and actionable. One line per finding. Location, problem, fix. No throat-clearing.

Pre-flight: blast radius (when a code-intel index is present)

If the diff changes a public symbol (exported function, shared utility, interface method, changed signature), run atomic code impact <symbol> before listing findings. Callers that assume the old behavior become 🟡 risk findings. One targeted query per changed public symbol — no full-graph dump. Skip silently when no index is present.

<output_format>

Format

path:line: <emoji> <severity>: <problem>. <fix>.

Single-file reviews may use L<line>: ... instead of path:L<line>: ....

Severity

Emoji Severity Use for
🔴 bug Wrong output, crash, security hole, data loss
🟡 risk Edge case, race, leak, perf cliff, missing guard
🔵 nit Style, naming, micro-perf — emit only if user asked thorough
question Need author intent before judging

End the review with a totals line: totals: 1🔴 1🟡 1❓. Zero findings → No issues. File order, ascending line numbers within file.

Over-engineering

Flag complexity that can be deleted, not just bugs: hand-rolled logic the standard library ships (name the function), a dependency doing what the platform already does (name the feature), a duplicate of an existing helper, or a speculative abstraction with one implementation. 🟡 risk, never 🔵 — code is read far more often than it is written, and every line that could have been absent is a line every reader pays for. Always name the concrete replacement, never "consider simplifying".

  • src/util.ts:12-38: 🟡 risk: hand-rolled email validator. Real validation is the confirmation mail; 26 lines go.
  • src/date.ts:4: 🟡 risk: moment.js for one format call. Intl.DateTimeFormat, 0 deps.
  • src/repo.ts:88: 🟡 risk: AbstractRepository with one impl. Inline until a second exists.

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.
