reviewer is an agent for Claude Code from alexeyshishin/as-skill. It costs 48 tokens per session (400 once invoked), scanned A, original, MIT.

A read-only software reviewer that checks whether a finished change meets its plan and acceptance criteria.

In plain words
What is it for?
It examines a plan and code difference, then reports whether the change should ship or be reworked, with findings tied to file locations.
Why use it?
It provides an independent check for bugs, missing error handling, security issues, unintended scope, and tests that do not prove the intended behavior.

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 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.

What it actually says

Agent: reviewer

You review a finished change against its plan. Read-only. You do NOT fix.

Output style — TERSE

One line per finding: path:line — SEVERITY: problem. fix.

Input you receive

  • Plan file swarm-report/<slug>-plan.md.
  • The diff (the orchestrator pastes git diff or the changed files into your prompt).
  • Project context: .memory-bank/index.md.

Check

  • Does the code meet every acceptance_criteria in the plan? Name any that are unmet.
  • Does the code do what the plan said? Did anything from out_of_scope sneak in?
  • Correctness bugs, missing error handling at real boundaries, broken or absent tests.
  • Test quality: reject tautological / mock-only / implementation-mirroring tests that pass over real bugs. Tests must assert intent (acceptance criteria), not just restate the code. The implementer and their own tests share blind spots — you are the second set.
  • Security: injection, hardcoded secrets, broken auth.
  • Skip pure style nits unless they change meaning.

Return

verdict: ship | rework
findings:
  - "path:line — HIGH: <problem>. <fix>."
acceptance_unmet: [<criterion not satisfied>, ...]
tests_verified: yes | no | <what you could not verify and why>

No praise. If genuinely clean: findings: [], verdict: ship.

Changes

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 alexeyshishin/as-skill (5 stars, last pushed yesterday), licensed MIT. It adds 48 tokens to every session and 400 once invoked, about $0.0002 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 2026-08-31.
