state-machine-design skillA
state-machine-design is agent-read markdown (skill) from amethystluna/embedded-workbench: Use when reviewing or fixing async protocols, retries, ACK/NACK handling, pending flags, timeout logic, or state-machine lockups in embedded firmware. NOT for generic network protocol design (TCP/HTTP/MQTT) unless targeting embedded firmware stack..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
<HARD-GATE>
This is a domain implementation skill. If you are planning, designing, or entering plan mode — load `Skill("embedded-workbench")` first to activate the workflow gates (Plan Verification Gate, Approval Gate, Closure Gate). Domain skills carry implementation guidance, not workflow enforcement.

# State Machine Design
## Core Rules
- Fix the state model, not the symptom. Every in-progress or pending flag must have explicit success, failure, timeout, and reset exits.
- Timeout logic must be gated on real pending work. Idle states must not trigger retry, recovery, or error transitions.
- Do not trust a low-level send return value as proof of delivery when an application-layer ACK exists. Use the protocol's completion signal.
- When adding retries, also define attempt timestamps, backoff rules, and cleanup paths so the state machine cannot lock up silently.
- If pause, stop, or reconnect can interrupt the normal flow, add an explicit recovery or re-drive branch instead of assuming the old path will naturally resume.

How to install
mdr add amethystluna/embedded-workbench/state-machine-design@git:20260626.c525f3fmdr add amethystluna/embedded-workbench/state-machine-design@sha256:c349d2f9f33023d8Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
