sakai SKILL.md skillA

sakai from i2y/ritsu is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add i2y/ritsu/sakai@git:20261103.5190146

Pins git:20261103.5190146 in mdr.lock. Pin the fingerprint instead.

Write, check and fix sakai files (`.ctx`), the checkable part of a context map — which bounded context owns each artifact, which relationships (conformist, anticorruption layer, customer and supplier, shared kernel, partnership, separate ways) let a reference cross a boundary, and how an anticorruption layer maps the enum values and terms that cross — held to real rules, workflows, calendars, books, `.proto` files, OpenAPI and AsyncAPI documents and code. Use when a context map has to be…

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 **context map that the code is held to**: which team's context owns which files, which context may use which other context's published language or call its services, and what an anticorruption layer does with each value that crosses.
sakai writes it as `.ctx` files beside the artifacts and checks every artifact against it.

It does not apply to what the code does inside a context, to the meaning of a definition, or to calls no contract writes (a URL in a string with no OpenAPI document, a queue with no AsyncAPI document, a shared database).
sakai checks none of those. The HTTP operations and the channels that OpenAPI and AsyncAPI documents write, it checks.

The files bundled with this skill are `reference.md` (the whole language and the commands), `targets.md` (the import linters and CML) and `codes.md` (every diagnostic).
Read them when you need them, not all up front.

# Working with sakai

Your part is to write the map, get it past `ritsu sakai check`, write the linters' settings and the page for people.
Two things stay with people:

How to install

The exact contents, by fingerprint
mdr add i2y/ritsu/sakai@sha256:532c576080ec0a17

The line at the top of this page pins the label git:20261103.5190146, 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.
