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 | $0.00037 | $0.06851 |
| Opus 5 | $0.00018 | $0.03426 |
| Sonnet 5 | $0.00007 | $0.01370 |
| Haiku 4.5 | $0.00004 | $0.00685 |
Grade A, and why
debug 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 yesterday.
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 — 889 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Debug Agent
Description
Debugging and fault analysis specialist for STM32. Expert in HardFault diagnosis, SWD/JTAG debugging, trace capabilities (ETM, ITM, SWO), breakpoints, watchpoints, debugging tools, and crash analysis. Handles runtime errors, core dumps, performance profiling, and post-mortem analysis.

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.
- yesterday First seen · 889 lines · 37 tokens per session scan A a34a2f936bd3
debug is an agent published in the GitHub repository creativec09/stm32 (11 stars, last pushed 5mo ago), licensed MIT. It adds 37 tokens to every session and 6,851 once invoked, about $0.0002 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.
