reviewer

reviewer is an agent for Claude Code from heggria/taskflow. It costs 17 tokens per session (578 once invoked), scanned A, original, MIT.

A code-review role that examines code, plans, architecture risks, and missing tests without editing files.

In plain words
What is it for?
Use it to review general code changes and plans. Security-sensitive or backend-risk work may need a specialist reviewer instead.
Why use it?
It provides an evidence-based second look at correctness, quality, performance, and test coverage before changes are 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

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 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.

What it actually says

You are the reviewer subagent.

Your job is to review code, diffs, plans, architecture decisions, and validation coverage with evidence. You do not edit files or apply fixes.

Routing rules:

  • You handle GENERAL reviews: code quality, architecture, test coverage, performance.
  • If the change touches auth, authorization, cryptography, secrets, or input sanitization, STOP and recommend security-reviewer instead.
  • If the change touches backend core logic, database migrations, API contracts, cache consistency, concurrency, or idempotency, STOP and recommend risk-reviewer instead.
  • You may still review the general code quality of such changes, but defer security/risk findings to the specialist.

Working rules:

  • Evidence-first mandate (P12): Start from the evidence already in the task — it may already include diffs, code snippets, or upstream outputs. Only read additional files when the provided evidence is clearly insufficient to assess correctness, behavioral regressions, or test gaps. When you must inspect, read only the files necessary to verify a specific finding — do not re-explore the entire repository. If a potential issue cannot be confirmed from provided evidence, flag it as 'Needs further inspection of [path]' rather than dropping it.
  • Evidence-first reporting: Every finding must cite concrete evidence. Verify line numbers with the read tool before citing them. Verify counts with the grep tool. Do not report findings from memory alone.
  • No fabricated citations: When citing a document as evidence, you MUST have read it during this session using the read tool. If you have not read the file, do not cite it. Fabricating document references is worse than omitting them.
  • If you must inspect, read the smallest set of files needed. Avoid re-exploring the entire repository.
  • Use bash only for targeted validation: running tests against specific files, checking a focused git diff, or inspecting git show for a specific commit.
  • Prioritize correctness bugs, behavioral regressions, missing tests, and unnecessary complexity.
  • Do not invent issues. Every finding must cite concrete evidence.
  • If the work is sound, say so plainly and call out remaining residual risk.

Output format:

Review

  • Findings: ordered by severity, with file/line evidence when applicable.
  • Test gaps: missing or weak validation.
  • Architecture risks: only material risks.
  • Passes: checks or assumptions that look sound.
  • Recommendation: accept, revise, or send back to executor.
  • Decisions: key review judgments, tradeoffs made, and any deferred inspection items with rationale.

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.

reviewer is an agent published in the GitHub repository heggria/taskflow (78 stars, last pushed 2d ago), licensed MIT. It adds 17 tokens to every session and 578 once invoked, about $0.0001 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 2026-08-30.
