state-machine-design SKILL.md skillA
state-machine-design from amethystluna/embedded-workbench is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add amethystluna/embedded-workbench/state-machine-design@git:20261018.2d04c6bPins git:20261018.2d04c6b in mdr.lock. Pin the fingerprint instead.

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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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.
</HARD-GATE>
# State Machine Design
> **For a design that has to be decided rather than reviewed:** `dsh-model-everything` verifies the machine itself — `model_verify` explores every interleaving for unreachable states, deadlock, a timeout that can never fire, and a lock held across an await; `model_compose_verify` decides two mechanisms interacting, including a lost update on a shared location. Load its `model-everything` skill when the plugin is installed. This skill stays the implementation guide: the C code, the flags, the timeouts.
## 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.

How to install
mdr add amethystluna/embedded-workbench/state-machine-design@sha256:8e4b8fba19fac4abThe line at the top of this page pins the label git:20261018.2d04c6b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
