Builds one vertical slice inside one bounded context, test first: the behaviour of the aggregate, the command or query with its permission, the handler, the route and their specs, generated then filled. Use when the user asks for a feature, an endpoint, a business rule or "add the ability to ...", or to build the next row of docs/architecture/slices.md. For a single file use scaffold; for a reaction to another context use integration-event.
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
# Build one use case Context: `$0`. Use case: `$ARGUMENTS` One use case, one context, one commit. Read `src/contexts/$0/CONTEXT.md` and the row of `docs/architecture/slices.md` when there is one; do not browse the tree (`npx ddd-ts-kit describe $0 --json` says what exists: use cases, routes, events, ports). Write it in a worktree, not in the main checkout of the trunk (the guard refuses it there in a project whose config says `"worktrees": "required"`): `npx ddd-ts-kit worktree <use-case>` opens `.worktrees/<use-case>` on its own branch, installed; then every command is `cd <worktree> && ...` and every file is written by its absolute path under it. A worktree of a story or of a worker already is one. ## 1. State it in the domain's words In five lines, before any command: who asks (the actor and the **permission** `<aggregate>.<action>`, or public, said explicitly), what must be true before, what changes, which fact is recorded, each way it can fail, by business name. Every noun and verb is in the glossary, or is added with `--term`. Stop if the slice writes in two contexts: one decides, …

How to install
mdr add gbourgeat/ddd-ts-kit/use-case@sha256:0e27153e1d356cf3The line at the top of this page pins the label git:20261019.17189a9, 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.
