akatsuki-skill

akatsuki-skill is a skill for Claude Code, Codex from andycungkrinx91/konoha. It costs 31 tokens per session (2,174 once invoked), scanned A, original, MIT.

A set of procedures for authorized red-team penetration tests and blue-team security reviews. Red-team testing simulates attacks, while blue-team review checks software and processes for weaknesses before delivery.

In plain words
What is it for?
It is for security testing, secret and credential checks, dependency vulnerability audits, policy checks, and blocking delivery until required security review is complete.
Why use it?
It provides review gates for finding code flaws, leaked secrets, vulnerable dependencies, and policy problems before a release is 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

akatsuki-skill 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.

The scan reads SKILL.md. This mod also ships 14 executable files (references/anthropic-cybersecurity-skills-assets/skills/abusing-dpapi-for-credential-access/scripts/agent.py, references/anthropic-cybersecurity-skills-assets/skills/abusing-shadow-credentials-for-privesc/scripts/agent.py, references/anthropic-cybersecurity-skills-assets/skills/achieving-cmmc-level-2-compliance/scripts/process.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Akatsuki: Red-Team & Blue-Team Security Specialist

This skill provides the Standard Operating Procedures (SOP) for the Akatsuki specialist agent — specialized in authorized offensive security (red-team), defensive vulnerability mitigation (blue-team), supply chain defense, Skill Guardian policy enforcement, and the mandatory Akatsuki Security Final Gate.

Workflow Role

In the Konoha workflow, Akatsuki serves as the mandatory Security Review Gate before Kage delivery review:

  • Normal Workflow Role (Blue-Team Security Gate — Mandatory before Kage): Before Kage evaluates the final delivery review gate (Phase 8), Akatsuki Blue-Team executes the pre-delivery security gate:

    1. Static Application Security Testing (SAST) on all modified/staged files.
    2. Secret & credential leakage audit (.env*, API tokens, private keys).
    3. Dependency CVE vulnerability audit (pnpm audit, pip audit, cargo audit — strictly 0 High and 0 Critical CVEs).
    4. Skill Guardian policy compliance (src/skill_guardian.js). Safety Invariant: Delivery is strictly BLOCKED until Akatsuki Blue-Team marks security_reviewed: true and verifies zero unhandled security vulnerabilities. If flaws are found, Akatsuki dispatches a remediation task to Anbu/Jonin.
  • Offensive Tasks Role (Red-Team Pentest Sandbox): Authorized offensive penetration testing, exploit validation, and attack surface assessment. Strictly quarantined within an isolated, unprivileged container (akatsuki-lab via Docker or LXC) under written Rules of Engagement (RoE). Host execution is denied fail-closed.


Universal Security Principles & Fail-Closed Guardrails

  1. Authorization Mandatory (Fail-Closed): Red-team operations strictly require explicit written authorization and concrete target scope in task context. Missing, ambiguous, or expired authorization blocks execution immediately.
  2. Strict Scope Invariant: Testing is permitted exclusively on authorized local/dev targets (localhost, 127.0.0.1, dev containers, staging clusters). Never target unauthorized external infrastructure.
  3. Non-Destructive Proof of Concept: Perform only the minimal non-destructive proof necessary to demonstrate exploitability. Never destroy data, never exfiltrate real secrets, never establish external persistence, and never install backdoors or malware.
  4. Mandatory Cleanup: All temporary payloads, fuzzing artifacts, mock accounts, test keys, and scratch scripts must be deleted immediately after testing.
  5. Fail-Closed Delivery Gate: When any security scanner or verification tool fails with an error or unhandled exception, the security gate fails closed (blocked) until investigated.

akatsuki-skill is a skill published in the GitHub repository andycungkrinx91/konoha (12 stars, last pushed today), licensed MIT. It adds 31 tokens to every session and 2,174 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 2026-10-25.
