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 | $0.00040 | $0.00651 |
| Opus 5 | $0.00020 | $0.00326 |
| Sonnet 5 | $0.00008 | $0.00130 |
| Haiku 4.5 | $0.00004 | $0.00065 |
Grade A, and why
mqtt-embedded-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 10d 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.

MQTT Embedded Integration
Overview
Use this skill for MCU MQTT clients by separating network link, TCP/TLS transport, MQTT session state, topic design, QoS, keepalive, and reconnect policy. MQTT success requires more than one successful publish.
When To Use
Use this skill when:
- The user wants MQTT on an MCU or embedded device.
- The task involves MQTT connect, publish, subscribe, keepalive, QoS, Last Will, retained messages, broker auth, TLS, reconnect, or offline buffering.
- The issue is connection drops, no messages, duplicate messages, memory growth, TLS failure, or reconnect storms.
Do not use this skill when basic IP connectivity is not working. Use lwip-integration or platform network debugging first.
First Questions
Ask for:
- MQTT library/client and version.
- Network stack, RTOS, transport, and whether TLS is used.
- Broker address, port, auth method, and certificate model without asking for secrets.
- Client ID, topics, QoS levels, keepalive, and reconnect policy.
- Current logs, broker logs, packet capture, or error codes.
- RAM budget and maximum payload size.
Integration Checklist
-
Prove network first. Confirm DNS/IP, TCP connect, and broker reachability before MQTT debugging.
-
Configure identity. Client ID must be unique and stable enough for the product.
-
Bound payloads and buffers. Topic length, payload size, QoS queues, and offline buffers must fit RAM.
-
Set keepalive and reconnect policy. Avoid reconnect storms; use backoff and clear session behavior intentionally.
-
Add TLS deliberately. Validate time, CA storage, certificate chain, SNI, and heap usage.
-
Verify broker behavior. Test subscribe, publish, QoS behavior, retained messages, and Last Will if used.
Common Failures
- Two devices use the same client ID and kick each other off.
- TLS fails because device time is invalid.
- Keepalive too short for poor networks.
- QoS 1 duplicates are not handled idempotently.
- Offline queue grows without bounds.
- Topic wildcards subscribe to too much traffic for MCU RAM.
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.

mqtt-embedded-integration is a skill published in the GitHub repository easyzoom/aix-skills (31 stars, last pushed 1mo ago), licensed MIT. It adds 40 tokens to every session and 651 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.
