code-review-action: Skill for Claude Code

.agents/skills/security-audit/SKILL.md

security-audit is a skill for Claude Code, Codex from julien777z/code-review-action. It costs 70 tokens per session (2,309 once invoked), scanned A, a copy of security-audit, MIT.

A code review focused on security problems that an attacker could actually use in web apps, APIs, services, command-line tools, libraries, and background programs.

In plain words
What is it for?
Use it to investigate security bugs, review a codebase for vulnerabilities, or test whether its code can be attacked.
Why use it?
It helps find vulnerabilities with real impact instead of spending time on theoretical issues or normal industry behavior.

Written for no agent in particular: nothing here depends on one. Also seen: mentions subagents; installed under .agents/ (shared by several agents).

This is julien777z/code-review-action's own configuration. It tells Claude Code and Codex how to work on code-review-action itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything code-review-action configures →

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

security-audit 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 6d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (render-artifacts.cjs, validate-findings.cjs), 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.

How it starts

The opening of the file, as written. The whole thing — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Security Audit

You are a security auditor. Your job is to find exploitable vulnerabilities with real impact.

Platform terminology

This skill is agent-neutral. In the methodology:

  • Task tool means the coding agent's delegation or sub-agent mechanism.
  • research agent means a delegated agent optimized for focused codebase exploration and factual verification.
  • general agent means a delegated agent that can investigate broadly and spawn focused research agents.
  • subagent_type means the equivalent delegated-agent role supported by the current platform.

Use the platform's equivalent capabilities while preserving the specified roles, parallelism, prompts, and independence boundaries.

Setup

Before starting, establish two paths:

  • Target: the codebase to audit (from the user's request or the current working directory)
  • Output directory: where all audit artifacts go. Ask the user if not specified, or default to audits/security-audit-skill/run-<N> inside the target repository (i.e. relative to the repo root / current working directory — do NOT add a <repo-name> segment, since the path is already inside that repo), where <N> is the next unused integer (check what exists with ls). Create it if it doesn't exist. This ensures multiple runs against the same repo produce separate results and that the artifacts live with the code they describe.

All files written during the audit go in the output directory:

  • architecture.md — Phase 1 output, fed into Phase 2 agent prompts
  • findings.json — the single source of truth for every finding (Phase 4)
  • summary.json — the single source of truth for the run-level narrative: report title and preamble, executive summary, baseline comparable, any run-specific context sections, hardening notes, positive patterns, coverage (Phase 4)
  • REPORT.md — human-readable report, generated from findings.json + summary.json
  • FINDINGS-DETAIL.md — detailed data flows for MEDIUM+ findings, generated from findings.json
  • PLAN.md — per-finding remediation plan with approval checkboxes, generated from findings.json + summary.json and presented to the user (Phase 7). Decisions are recorded in the JSON, never by editing this file.

What ships with it

8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

security-audit is a skill published in the GitHub repository julien777z/code-review-action (2 stars, last pushed yesterday), licensed MIT. It adds 70 tokens to every session and 2,309 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 81% identical to security-audit, differing in 37 lines, and is treated as a copy.
