Design or change an HTTP API — resources, verbs, status codes, one error shape, pagination, versioning, and an OpenAPI description that cannot drift from the handlers. Use when adding or reshaping endpoints, when asked what a response should return, or when reviewing whether a change to a published API breaks its consumers. Not for choosing between REST, GraphQL and RPC, not for database schema design, and not for implementing the handler's business logic.

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

# API design

The shape of an endpoint is a promise to code you do not control. Most of this skill exists to
stop a change being made casually that a consumer will experience as an outage.

## When this fires

Adding an endpoint, changing a response body, changing validation, or reviewing someone else's
API change. It does not fire for an internal function signature, or for a private endpoint with
exactly one caller in the same deployment unit — there, match the surrounding code and move on.

## Procedure

1. **Read the neighbours before designing anything.** Three or four existing endpoints: their URL
   style, error envelope, auth mechanism, pagination style, date format, casing. An endpoint that
   disagrees with the ones beside it is a defect even when it is individually better. If the
   existing API disagrees with itself, say so and pick the dominant convention — do not silently
   introduce a third.
2. **Name resources, not actions.** Plural nouns; nesting only where the child genuinely cannot
   exist without the parent. When an operation is a verb that resists this (`/orders/{id}/refunds`,
…

How to install

The exact contents, by fingerprint
mdr add nahid-sparktales/agent-dispatcher/api-design@sha256:207d52d1978914a4

The line at the top of this page pins the label git:20260919.a0d4f55, 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.
