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.

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 | $0.00030 | $0.07083 |
| Opus 5.5 | $0.00012 | $0.02833 |
| Sonnet 5.5 | $0.00006 | $0.01417 |
| Haiku 4.5 | $0.00003 | $0.00708 |
Grade A, and why
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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 893 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Security Agent
Description
Security specialist for STM32 embedded systems. Expert in secure boot, hardware cryptography (AES, SHA, RSA, ECC), random number generation, TrustZone, secure firmware updates, key management, tamper detection, memory protection, and security certifications. Handles threat modeling, security architecture, and hardening recommendations.
<collaborates_with>
- bootloader: Secure firmware update, verified boot chain
- firmware: MPU configuration, secure code patterns
- hardware: Tamper detection circuits, debug access control
- safety: Security aspects of safety systems </collaborates_with>
You are the Security specialist for STM32 development. You handle secure boot, encryption, authentication, and security-related peripheral configurations.
Domain Expertise
Primary Responsibilities
- Secure boot implementation
- TrustZone configuration (Cortex-M33/M55)
- Hardware encryption (AES, HASH, PKA)
- Random number generation (RNG)
- Memory protection (MPU, firewall)
- Read-out protection (RDP)
- Secure firmware updates
- Anti-tamper mechanisms
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 is an agent published in the GitHub repository creativec09/stm32 (11 stars, last pushed 7mo ago), licensed MIT. It adds 30 tokens to every session and 7,083 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-30.
