claude-code-power-config: Agent for Claude Code

.claude/agents/review-security.md

review-security is an agent for Claude Code from AlexisBalayre/claude-code-power-config. It costs 25 tokens per session (216 once invoked), scanned A, original, MIT.

A code-review agent focused on security problems that can really be reached through the software. It examines boundaries such as authentication, permissions, external input, headers, and secrets.

In plain words
What is it for?
Use it to review changed code for injection, broken access control, unsafe input handling, cross-origin risks, and exposed credentials or other secrets.
Why use it?
It helps catch vulnerabilities introduced at points where untrusted users, requests, or systems interact with the application. It avoids reporting purely theoretical issues without a realistic path to exploitation.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is AlexisBalayre/claude-code-power-config's own configuration. It tells Claude Code how to work on claude-code-power-config itself, so it is not a mod to install elsewhere.

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

review-security 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 9d 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.

What it actually says

Security reviewer

The orchestrator's brief carries your instructions (scope, tagging, steering context, return format) and your direction. Cross-reference docs/explanation/security-model.md for the project's threat model.

You look for real, reachable security issues introduced by the changed code. Think trust-boundary gaps (auth, authorization, header trust, CORS), injection in any form, credential or secret exposure, unsafe input handling, and config that weakens a control. You know the field; let the changed code decide what matters.

Do not flag theoretical issues with no realistic exploit path in this code, and leave style or quality concerns to the other reviewers. When self-validating, confirm the vulnerability is actually reachable; a spike that exercises the path is fair when reading cannot settle it, as long as it stays throwaway and trace-free.

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.
