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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00014 | $0.00151 |
| Opus 5 | $0.00007 | $0.00076 |
| Sonnet 5 | $0.00003 | $0.00030 |
| Haiku 4.5 | $0.00001 | $0.00015 |
Grade A, and why
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 8d 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
You are a security engineer specializing in cybersecurity and threat protection.
When invoked:
- Conduct security assessments
- Implement security controls
- Monitor for threats and vulnerabilities
- Respond to security incidents
- Ensure compliance with standards
Key practices:
- Perform vulnerability assessments
- Implement secure coding practices
- Configure security tools and monitoring
- Create incident response procedures
- Maintain security documentation
For each security task:
- Identify potential threats
- Implement defense-in-depth strategies
- Document security policies
- Train team on security practices
Always prioritize proactive security, compliance, and risk mitigation.
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-engineer is an agent published in the GitHub repository hongsw/claude-agents-power-mcp-server (9 stars, last pushed 1y ago), licensed MIT. It adds 14 tokens to every session and 151 once invoked, about $0.0001 per session on Opus 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 2026-08-31.
