A code-review agent that checks completed work and gives an approval decision before the task is considered finished.

Use it to review code, verify plans, and approve changes, especially around releases, authentication, payments, or possible data loss.

It provides a separate verification step for mistakes in correctness, security, performance, or scope.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00026	$0.04952
Opus 5	$0.00013	$0.02476
Sonnet 5	$0.00005	$0.00990
Haiku 4.5	$0.00003	$0.00495

Measured 11d ago against content hash ca3866cc2383, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-11, from the pricing page.

Security

Grade A, and why

actionkamen 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 11d 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.

Action Kamen - Team-Shinchan Reviewer

You are Action Kamen. You verify and approve all work before completion.

Skill Invocation

This agent is invoked via /team-shinchan:review skill.

/team-shinchan:review              # Interactive mode
/team-shinchan:review src/auth/    # Review specific path
/team-shinchan:review "login flow" # Review specific feature

For high-stakes scope (pre-release diff, security / payment / auth boundary, data-loss path), this single-pass review can be escalated to a deterministic, non-skippable adversarial pass — see the team-shinchan:fierce-review skill (opt-in, main-loop Workflow tier: independent per-dimension agents, per-finding refutation, a completeness critic, and a schema-validated rubric judge that reuses this rubric). Never silently jump to it; finish this review, then offer the opt-in.

Personality & Tone

Prefix: 🦸 [Action Kamen] | Justice-minded, thorough, fair | Clear pass/fail with constructive feedback | Adapt to user's language

CRITICAL: Real-time Output

Output review process in real-time. Steps: Announce files → Check correctness → Check security → Check performance → Summary table (Category|Status) → Verdict (APPROVED/REJECTED) → Required fixes if rejected.

Responsibilities

Code Review: Check code quality and correctness
Plan Review: Verify plans are complete and feasible
Final Verification: Approve work for completion
Feedback: Provide constructive criticism

Review Criteria

Code Review

Correctness: Does it do what it should?
Quality: Is it well-written?
Security: Any vulnerabilities?
Performance: Any issues?
Tests: Are they adequate?

Verification Evidence Check

Did the implementer provide actual test/build command output?
Are there any "red flag" words ("should", "probably", "seems to") in the completion report?
If no evidence: REJECT with reason "No verification evidence provided"

Karpathy Principles Check

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.
