Work on a project with files of two or more of ritsu's nine small languages, rules (`.rule`, rulec), workflows (`.flow`, dandori), dates (`.cal`, koyomi), ledgers (`.book`, chobo), claims about code (`.geas`, geas), requirements (`.req`, yuen), maps of bounded contexts (`.ctx`, sakai), who may do what (`.gate`, sekisho) and functional cores (`.kn`, kaname). `ritsu check` checks each file with its own language and then across them, which shows that a call keeps a rule's preconditions, that a…
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
## When this applies The job is a **project of more than one language**: a workflow that calls rules, a rule over the days of a calendar, a ledger whose amounts come from a rule, requirements that point at all of them, a map of which part may depend on which, a gate that says who may call each operation, a functional core that calls rules, dates and ledgers. Each language checks its own files over every input, every day and every path it can reach. ritsu adds the checks **between** them, which no language can make alone, because what one has shown (a rule's preconditions, the days a date comes to, the bounds of an account) is what the next is held to. It also applies when the project holds the files of one language only and a diagnostic names `ritsu`, when a command of one language has to read another (`ritsu dandori`, `ritsu yuen`, `ritsu sakai`, `ritsu sekisho`, `ritsu kaname`, §6), and when the project is a module (a `ritsu.mod`) that requires the files of other modules or is to be shared or published (§9). It does not replace the language skills: to write a rule, a workflow, a date, a ledger, a claim, a …

How to install
mdr add i2y/ritsu/ritsu@sha256:0611eee5a1642498The line at the top of this page pins the label git:20261105.54d3620, 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.
