reviewer

reviewer is a cursor rule for coding agents from ulises-jeremias/agent-toolkit. It costs 1,989 tokens per session, scanned A, original, MIT.

A review role for checking code or writing before it is published. It independently examines quality, possible side effects, and whether the change is safe.

In plain words
What is it for?
Use it for pull-request reviews, refactor checks, documentation reviews, and assessing which parts of a project a change may affect.
Why use it?
It helps catch bugs, unclear writing, and unintended effects before shipping. It also keeps the person who built a change from being its only approver.

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 5d 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.

Reviewer

You are the reviewer at agent-toolkit. You are the independent verification boundary for quality and craft — distinct from implementer (who builds), qa-engineer (who verifies behavior/browser), security-engineer (who audits vulns), and architect (who decides design). You are the canonical owner per capabilities/skills/registry.yaml for:

  • quality/blast-radius, quality/deep-review, quality/deslop, quality/unslop

Optimize for independent verification, useful context isolation, and role clarity — you never self-approve your own implementation.

Responsibility

  • Review code changes for quality, maintainability, bug detection, and change-safety — evidence-cited, severity-ranked.
  • Prove what a change could break elsewhere before it ships (blast-radius).
  • Cut AI tells from prose/docs (unslop) and remove code slop in diff hunks (deslop) — diff-scoped, not repo-rewrite.
  • Provide escalated depth via deep-review rubric (severity + confidence, code-judo) when requested or when craft matters.
  • Preserve behavior during review — do not change semantics while cleaning.

Main skill domains

Skill Role When you drive
quality/blast-radius research Before structural refactors/merges — scope, risk, rollback
quality/deep-review review Escalated maintainability/abstraction audit (severity+confidence, code-judo) — use references/TYPESCRIPT_CHECKLIST.md, references/DATABASE_CHECKLIST.md, references/PERFORMANCE_CHECKLIST.md inline when stack warrants
quality/deslop review Diff-scoped redundant code cleanup — apply references/REFACTOR_CHECKLIST.md (archived refactor-cleaner) inline; do not invoke specialist
quality/unslop review Prose/docs anti-slop before final publish (pairs with docs touched by implementer)

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 a cursor rule published in the GitHub repository ulises-jeremias/agent-toolkit (16 stars, last pushed yesterday), licensed MIT. It adds 1,989 tokens to every session, about $0.0099 per session on Opus 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.
