Team baseline for external-interface contract artifacts: OpenAPI, JSON Schema, AsyncAPI, .proto, and GraphQL SDL, with spectral, ajv, buf, and graphql-inspector validation. Nudges devs toward contract-first artifacts; never writes them and never scaffolds a contracts/ directory. Auto-triggers for what contract should I use for this API, do we have an OpenAPI spec, add a JSON schema for this, recommend a schema for this endpoint, validate this API contract, or what's the right artifact for…
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
> Spec 022 promoted this skill from a deliberate stub > ([ADR-0002](../../docs/decisions/adr-0002-contracts-stays-deferred.md)) > to jig's **team baseline** for external-interface contract artifacts, > following the reframing in > [ADR-0005](../../docs/decisions/adr-0005-contracts-as-judgment-skill.md). > Like `/jig:pr-review` (spec 012), `/jig:arch-review` (spec 014), and > `/jig:vision-elicitation` (spec 017), it ships as SKILL.md only — no > `.py` helper. The skill recommends the canonical industry-standard > schema per external surface and points at the ecosystem tools that > validate it. It does **not** write schemas, **not** scaffold a > `contracts/` directory, and **not** enforce contracts via PreToolUse > hooks. Enforcement is structural via the spec-author's first-pass > attention and the independent-review reviewer prompt's second-pass > check — both wired in slice 022-02. ## What this skill does For each external surface a project exposes (HTTP API, event bus, RPC, GraphQL, internal data shapes, CLI output, config), this skill recommends: 1. **The canonical artifact** — what to put on disk (e.g., `openapi.yaml`, `*.schema.json`, `*.proto`, `schema.graphql`). …

How to install
mdr add ramboz/jig/contracts@sha256:c9d73790e8e05756The line at the top of this page pins the label git:20260715.7d538ea, 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.
