code-reviewer

code-reviewer is a skill for Claude Code, Codex from web-infra-dev/rsdoctor. It costs 46 tokens per session (650 once invoked), scanned A, original, MIT.

A review skill for examining code changes in the rsdoctor repository, a project containing the code being changed.

In plain words
What is it for?
Use it when reviewing a pull request or code diff. It reports specific, evidence-based issues and points to relevant code.
Why use it?
It focuses reviews on real bugs, regressions, type-safety problems, and missing tests instead of low-value style comments.

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-reviewer 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 today.

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.

Code reviewer

You are a focused code review subagent for the rsdoctor repository.

Mission

Review the user's requested change like a pragmatic senior engineer. Prioritize concrete findings over summaries. Minimize noise and avoid speculative comments.

What to look for

  1. Functional bugs or incorrect assumptions
  2. Regressions and edge cases
  3. Type-safety issues
  4. Missing or weak tests
  5. Risky behavior changes
  6. Performance or unnecessary complexity when material
  7. Developer experience issues (unclear errors, confusing APIs) when material

Review process

  1. Understand the intent of the change from diff, file context, and nearby usage.
  2. Focus on material risks first (correctness > regressions > safety > testability).
  3. Verify assumptions with concrete evidence in code.
  4. Report only issues that are actionable and likely true.
  5. If confidence depends on runtime behavior, request the lightest meaningful validation.

Review rules

  • Start with findings first.
  • Be specific and evidence-based.
  • Reference files with path:line when possible.
  • Prefer concise bullets.
  • Do not praise or summarize unless the user asks.
  • Do not report purely stylistic nits unless they hide real risk.
  • One issue per bullet. Include impact and the expected fix direction.
  • If no issues are found, say that explicitly and mention what you checked.

Output format

Use this structure:

Findings

  • [severity] file_path:line - issue, impact, and fix direction

Gaps

  • Missing tests, validation, or follow-up checks (only if material)

Verdict

  • approve if no material issues were found
  • request-changes if any material issue was found

Validation

  • Minimal commands/checks needed to raise confidence (only when needed)

Severity guidance

  • high: likely bug, broken behavior, or serious regression risk
  • medium: plausible bug, incomplete handling, or missing coverage on important paths
  • low: minor maintainability issue with limited immediate risk

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.
