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 | $0.00041 | $0.00592 |
| Opus 5 | $0.00020 | $0.00296 |
| Sonnet 5 | $0.00008 | $0.00118 |
| Haiku 4.5 | $0.00004 | $0.00059 |
Grade A, and why
nanopb-integration 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 11d 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.

nanopb Integration
Overview
Use this skill to integrate nanopb by controlling schema size, generated options, callbacks, and buffer ownership. Embedded protobuf failures usually come from mismatched generated files, unbounded fields, or callback misuse.
When To Use
Use this skill when:
- The user wants Protocol Buffers on an MCU using nanopb.
- The task involves
.proto,.options,nanopb_generator.py,pb_encode,pb_decode, repeated fields, strings, bytes, callbacks, or fixed-size arrays. - Encoding/decoding fails, messages are truncated, memory usage is too high, or host and device schemas mismatch.
Do not use this skill for general JSON/INI parsing. Use embedded-data-parsing-libs instead.
First Questions
Ask for:
- nanopb version and how code generation runs.
.proto,.options, generated.pb.c/.pb.h, and host-side schema version.- Transport/storage where messages are sent.
- Max message size, RAM budget, and whether streaming decode is needed.
- Current encode/decode error and sample payload if available.
Integration Checklist
-
Lock schema and generated files together. Regenerate
.pb.c/.pb.hwhenever.protoor.optionschanges. -
Bound variable fields. Use nanopb options for max string, bytes, repeated field, or callback-based streaming.
-
Size buffers explicitly. Know max encoded size and transport frame limits.
-
Check return values. Always inspect
pb_encode/pb_decodefailure and error text. -
Validate compatibility. Test device-generated payload with host decoder and host-generated payload with device decoder.
Common Failures
- Generated files are stale relative to
.proto. - Repeated/string fields need max sizes but default to callbacks.
- Decode fails because the transport strips length framing.
- Device and host use different schema versions.
- Stack buffers are too small for worst-case message size.
- Callback decode stores pointers into temporary buffers.
Verification
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.

nanopb-integration is a skill published in the GitHub repository easyzoom/aix-skills (31 stars, last pushed 1mo ago), licensed MIT. It adds 41 tokens to every session and 592 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.
