Check a TLA+ model of a system that moves between states, such as a product flow, a protocol, or a service, and draw it as a Mermaid statechart. The report gives the shortest path to each state that breaks a rule. Use for /statechart, or to show a bug as a path through states.
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
# Statechart Read [the pstack-t3 runtime](../pstack-runtime/SKILL.md) before spawning workers, choosing models, scheduling, or isolating work. It maps those steps onto T3's orchestrator tools. The chart shows how a system moves between states, in the words of the person who reads it. That person, the reader, decides whether the behavior is right. ## Run Work in a scratch folder outside the repo. Write a TLA+ spec and its config. Then run: ```sh <skill dir>/scripts/statechart SPEC.tla [--config FILE] [--view FILE] [--out DIR] ``` `scripts/statechart.ts` is TypeScript, so run it with a runtime that can execute TypeScript. The first run installs TLC and Java with mise and needs the network. ## Write the spec - Write each rule that the reader agrees to as an INVARIANT. A rule can be about a screen, a result, a stored value, or a message. If the model has no variable for a rule, add the variable. Never weaken a rule to make it hold. - Write `Next` as a disjunction of the actions, such as `YouPressPlay \/ YouPressStop`. If you do not, TLC names every step `Next`. …

How to install
mdr add creedants/pstack-t3/statechart@sha256:d6cfe50f65220ca5The line at the top of this page pins the label git:20261027.0869d8b, 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.
