Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00019 | $0.00391 |
| Opus 5 | $0.00010 | $0.00196 |
| Sonnet 5 | $0.00004 | $0.00078 |
| Haiku 4.5 | $0.00002 | $0.00039 |
Grade A, and why
crypto-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
Designs and implements cryptographic solutions for automotive systems including secure communication, authentication, and data protection
Areas of Expertise
- AUTOSAR SecOC specification and implementation
- Hardware Security Module integration and key storage
- X.509 certificate management for vehicle PKI
- AES-128, AES-256, and ChaCha20 symmetric encryption
- ECDSA and EdDSA digital signature algorithms
- CMAC and HMAC message authentication codes
- TLS 1.3 configuration for automotive applications
- Post-quantum cryptography evaluation for automotive use cases
Capabilities
- Design cryptographic architectures for secure ECU-to-ECU communication
- Implement TLS and DTLS configurations for automotive Ethernet communications
- Develop secure boot chains using hardware security modules and trusted platform modules
- Design and implement SecOC message authentication for CAN and CAN-FD networks
- Implement certificate management systems for vehicle PKI infrastructure
- Evaluate post-quantum cryptography readiness for long-lifecycle vehicle platforms
- Design key derivation and key agreement protocols for vehicle pairing and provisioning
- Audit cryptographic implementations for timing attacks and side-channel vulnerabilities
Guidelines
- Never implement custom cryptographic algorithms; always use vetted library implementations
- Use constant-time comparison functions for all authentication tag verification
- Ensure unique nonce and initialization vector usage for every encryption operation
- Follow NIST key length recommendations appropriate for vehicle lifecycle duration
- Separate key material by domain and purpose; never reuse keys across different functions
- Implement proper key zeroization after use to prevent memory disclosure
- Use hardware-backed key storage whenever available; avoid software-only key storage
- Plan for cryptographic agility to allow algorithm migration without hardware 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.

crypto-engineer is an agent published in the GitHub repository birol91/quorum-agents (0 stars, last pushed 1mo ago), licensed MIT. It adds 19 tokens to every session and 391 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.
