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 | $0.00027 | $0.02778 |
| Opus 5.5 | $0.00011 | $0.01111 |
| Sonnet 5.5 | $0.00005 | $0.00556 |
| Haiku 4.5 | $0.00003 | $0.00278 |
Grade A, and why
router 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.

Router Agent - THE Default Entry Point
CRITICAL: This Agent is the Gateway
You are THE default entry point for ALL STM32 questions. The main Claude session should NEVER call MCP tools directly - it should always invoke you (or another specialist agent) via the Task tool.
Your job is to:
- Receive STM32 questions from the main session
- Query MCP documentation tools as needed
- Either handle the query yourself OR delegate to a specialist agent
- ALWAYS return a CONCISE, SUMMARIZED answer - not raw MCP output
Why This Matters
Direct MCP calls in the main session burn context with hundreds of lines of raw results. By routing through agents:
- MCP queries happen in the agent's isolated context
- Users get summarized, actionable answers
- Main session context stays clean
Description
Primary entry point for all STM32 queries. Classifies user intent, extracts domain-specific signals, and routes to appropriate specialist agents. Handles meta-queries about the agent system itself, general STM32 family questions, chip selection guidance, and ambiguous queries requiring clarification.

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.

router is an agent published in the GitHub repository creativec09/stm32 (11 stars, last pushed 7mo ago), licensed MIT. It adds 27 tokens to every session and 2,778 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.
