Tla Precheck
bootoshi · Agent
TLA PreCheck lets you write a state machine once in a restricted TypeScript DSL. Its compiler runs the TLC model checker over every reachable state within the bounded sizes you set, compares the TLA+ spec with the TypeScript interpreter, and generates a typed adapter and Postgres constraints from the same source. It needs Java installed. It is meant to be used by coding agents, which write only the machine, run the check and fix the design until the proof and equivalence checks pass.
Written by ooruby from the README of tla-precheck 0.1.7.

Why it's useful
Guards and transitions live in one checked definition rather than as status checks repeated across services.
What you could do with it
- Model a billing, subscription or agent-run flow as a machine and let the checker find states you missed.
- Call the generated create, cancel and complete functions instead of scattering status checks through your code.
- Loop your agent on the check command until the proof and equivalence checks both pass.
Written from its documentation: what it says it can do, not what our checks found.
Maintenance
Not measuredNo release date is on record for this package yet. The nightly publisher check records one as it reaches each npm package, about once every ten nights.
Release activity only: it says nothing about quality or safety, and a finished small package can be fine without releases. How it is measured
- Licence and provenance
- finding
- no LICENCE file at the root (.)
Published because it was found. A finding is information about where the limits are, not a verdict that the software is unsafe.
What this does not cover
- Everything. Treat it as you would software from anywhere else.
Receipt history: every signed receipt for every version of this listing, and what changed between them.
In its maker's words
Write state machines once in TypeScript. The compiler mathematically proves correctness via TLA+, then generates runtime code and Postgres constraints from the same source.

Static scanned
- What it establishes
- Its published package, or for a hosted server its source repository at a recorded commit, was read file by file, without running it, by every check in our current scan.
- What it does not
- How it behaves when it runs, or anything the scan does not read yet: several rubric checks, the repository's history, and compiled code in folders named dist or build. For a hosted server, that the endpoint runs the code that was read. The ooruby Index sets out exactly what was read.
- Exactly what was read
- Version 0.1.7, the file with digest sha512-UZeHqQhYeRm4rETI68fK1t9+bM7u3g3tqY40BG8aRjSx1K9j6R9Aj5IXsva+S+Nq62tsW/NsqlsHmxclwhRZ+g==, as the registry publishes it. A published version cannot be replaced, so this names the same bytes for anyone who checks.
- Authentication
- Runs locally. No hosted endpoint is listed for this package. You run it on your own machine, so there is no endpoint of ours to authenticate against.
Adding it
Run it with:
npx -y tla-precheck@0.1.7Pinned to 0.1.7, which is the version the findings above were found in. Drop the version to take whatever is newest, and the report on this page stops describing what you installed.

No build provenance published. The repository above is the one the publisher declared, and nothing links it to the package you would install. That is not a mark against this listing, since most packages are published this way, but it is a check nobody can run.

It renders the current rung (static scanned) and links back here, where what that does and does not establish is one click away. It updates itself as the evidence deepens.
