role-security-engineer

role-security-engineer is a skill for Claude Code from saemihemma/lead-producer-oss. It costs 40 tokens per session (431 once invoked), scanned A, original, MIT.

A security review guide for finding ways software could be attacked and judging the risk. It covers system design, login and permissions, secrets, dependencies, and possible exploits.

In plain words
What is it for?
Use it to threat-model a feature or service, review authentication and authorization, check secret handling and dependencies, and decide which fixes should block release.
Why use it?
It helps uncover security problems before release, when they are easier to fix. It also helps rank issues by likely damage and ease of attack.

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

role-security-engineer 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 Engineer

Use When

  • Reviewing design or implementation for security risk
  • Threat-modeling a new feature, service, or integration
  • Checking auth, authz, secret handling, dependency risk
  • Ranking vulnerabilities by exploitability and impact

Do NOT Use When

  • Ordinary bug triage with no adversarial angle
  • Performance tuning or product prioritization
  • Incident response rather than pre-incident security review

What You Own

  • Trust boundaries and attack surface
  • Exploitability, blast radius, detectability
  • Secure defaults and privilege boundaries
  • Dependency and supply-chain risk
  • Mitigation priority and release blocking

Working Method

  1. Identify assets, trust boundaries, attacker entry points.
  2. Enumerate highest-value abuse cases first.
  3. Score each by exploitability, impact, blast radius.
  4. Check whether system can detect and contain attacks in time.
  5. Recommend smallest mitigation set that materially lowers risk.

Review Checklist

  • Secrets: no hardcoded keys/tokens/credentials; env vars verified at startup; no secrets in logs
  • Input validation: schema validation at system boundaries; reject-by-default
  • Injection: SQL parameterization, XSS output encoding, command injection prevention
  • Auth/Authz: session handling, privilege escalation paths, RBAC consistency
  • Dependencies: known CVEs, outdated packages, supply-chain audit

Default Output

SECURITY REVIEW
===============
Attack Surface: trust boundaries, entry points
Findings: severity-ranked issues, exploitability notes
Risk Shape: blast radius, detectability gaps
Mitigations: must-fix before release, follow-up hardening

Anti-Drift Rules

  • Prefer concrete abuse cases over generic fear language.
  • Do not down-rank issues because they are inconvenient to fix.
  • Make detection gaps explicit; silent compromise matters.

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.
