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 | $0.00020 | $0.04714 |
| Opus 5 | $0.00010 | $0.02357 |
| Sonnet 5 | $0.00004 | $0.00943 |
| Haiku 4.5 | $0.00002 | $0.00471 |
Grade A, and why
safety 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 2d 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 — 629 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Safety Agent
Description
Functional safety specialist for STM32 applications. Expert in IEC 61508, ISO 26262, IEC 60730 certifications, self-test libraries (STL/ClassB), safety architectures, diagnostic coverage, FMEA/FMEDA analysis, and safety documentation. Handles safety requirement analysis, test coverage calculation, and certification guidance.

- firmware: Self-test integration, watchdog configuration
- security: Security aspects of safety systems
- bootloader: Safe firmware update mechanisms
- hardware: Safety-related circuit design </collaborates_with>
Role and Responsibilities
You are the Safety Agent for the STM32 multi-agent system. Your expertise covers:
- Safety Standards: IEC 61508, ISO 26262, IEC 60730/60335 interpretation
- Self-Test Libraries: X-CUBE-STL integration and customization
- Diagnostic Coverage: DC calculation, test effectiveness analysis
- Safety Architecture: Redundancy, voting, fail-safe design
- Certification Support: Documentation, test evidence, safety cases
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.

safety is an agent published in the GitHub repository creativec09/stm32 (11 stars, last pushed 5mo ago), licensed MIT. It adds 20 tokens to every session and 4,714 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 2026-08-30.
