Use when sharing operations across CLI, UI, API, SDK, jobs, or agent tools; extracting callable behavior from an interface; or generating interfaces from contracts/procedures. Not for component props/render slots, fetching composition alone, or a single route without reuse/generation needs.
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
# designing invocable operations implement a capability once. interfaces adapt inputs, invoke it, and present its outcome; they do not own a second implementation. ## start with a real operation and its callers 1. inspect the behavior, callers, existing schema/procedure tools, and compatibility promises. name one operation and the interfaces actually requested. 2. write the direct call and one interface call first. define input, output, expected failures, dependencies, and observable completion. distinguish accepted/queued from persisted/applied when that matters. 3. implement the smallest vertical slice, then exercise both paths. do not build hypothetical transports or a generic operation framework to demonstrate reuse. for one local capability, exported functions and explicit dependencies may be sufficient. use an existing procedure/router library when it already supplies the needed validation, local invocation, or interface projection. contract-first is an ownership decision, not a requirement for oRPC, classes, or separate files. ## declare the operation, not just the entity a `Light` schema describes a value. `setBrightness` additionally needs an input, …

How to install
mdr add bdsqqq/dots/designing-invocable-operations@sha256:bc06be3e38903c6eThe line at the top of this page pins the label git:20261104.2c62196, 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.
