Install it, pinned

mdr add developer-overheid-nl/skills-developer-overheid-nl/don-tools@git:20261009.f24f404

REST APIs bouwen voor de Nederlandse overheid, design-first: OAS genereren met oas-generator, valideren met don-checker, schemakeuze uit het schema-register, codegen.

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

# DON Tools

**Agent-instructie:** Deze skill bevat de praktische DON-tools voor API-ontwikkeling op [developer.overheid.nl](https://developer.overheid.nl). Bij het ontwerpen of bouwen van een REST API: volg de [API design-first werkwijze](#api-design-first-werkwijze) hieronder. Voor de normatieve regels uit de NL GOV API Design Rules (ADR) — naming, problem+json, transport security, etc. — zie de `ls-api` skill in [developer-overheid-nl/skills-standaarden](https://github.com/developer-overheid-nl/skills-standaarden).

## API design-first werkwijze

Volg de [Bouw een API-tutorial](../don-apis/references/aan-de-slag/bouw-een-api.md) (lokaal beschikbaar via de gesynchroniseerde `don-apis` kennisbank — de bron is [developer.overheid.nl](https://developer.overheid.nl/kennisbank/api-ontwikkeling/tutorials/bouw-een-api/)): eerst de OpenAPI Specification (OAS) als contract, daarna pas code. Doorloop deze flow in volgorde; gebruik `AskUserQuestion` voor elke vraag aan de gebruiker en valideer **altijd** (stap 6 en 10) voordat je een OAS oplevert. Lees de lokale referenties (zie [Bronnen](#bronnen)) voor diepere context wanneer nodig.

How to install

The exact contents, by fingerprint

mdr add developer-overheid-nl/skills-developer-overheid-nl/don-tools@sha256:fa3b35d6c35fb058

The line at the top of this page pins the label git:20261009.f24f404, 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.
