Generate machine-readable integration contracts (API, data layer, shared types, events) before any implementation begins in a multi-agent build or explicitly requested solo contract design. Use when authoring API contracts, OpenAPI specs, AsyncAPI specs, Pydantic models, TypeScript interfaces, JSON Schema definitions, data layer interfaces, shared type schemas, integration boundaries between agents, or domain business rules. Trigger on "write the API contract", "define the shared types…
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
# Contract Author > **Tradeoff:** Biases toward upfront design over ad-hoc assumptions. Prototype builds may have explicit minimal contract scope approved by the owner, but never skip contract boundaries entirely where services or components integrate. ## When this skill applies This skill defines integration contracts in contract-first multi-agent builds or explicitly requested solo contract work: - In native orchestration, the orchestrator dispatches role-agents after contracts are authored - Each implementation role consumes a machine-readable contract from `/contracts/` - `qe-agent` gates the build via `qa-report.json` - In solo builds, contracts establish the frozen interface boundary before implementation begins ### Execution mode …

How to install
mdr add ivy00johns/skill-madness/contract-author@sha256:988fda5ca28363f7The line at the top of this page pins the label v1.6.1, 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.
