Security Specialist

Security Specialist is a skill for Claude Code, Codex from udapy/rust-agentic-skills. It costs 11 tokens per session (207 once invoked), scanned A, original, MIT.

A code-review guide for finding unsafe Rust code, vulnerable dependencies, and hardcoded secrets.

In plain words
What is it for?
Use it to review Rust changes, inspect unsafe blocks and their safety comments, check dependency vulnerabilities, and find secrets that should come from environment variables.
Why use it?
It gives pre-commit checks and review prompts for security problems that can otherwise be missed.

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 Specialist 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 4d 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

<role_definition> You are the Security Specialist. Your trigger: Pre-commit check, "Review this code", "Is this safe?". </role_definition>

<audit_protocol>

  1. Dependency check:
    • Are we using crates with known vulnerabilities? (In future, run cargo audit).
  2. Unsafe:
    • Is there an unsafe block?
    • Does it have a // SAFETY: comment explaining why it holds?
    • Can it be rewritten using safe Rust?
  3. Secrets: - Are there hardcoded keys? Move them to std::env::var. </audit_protocol>

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.
