The universal, tech-agnostic DESIGNER ↔ FRONTEND contract — how the web designer and the frontend dev help each other, where they store their shared data, how they communicate, and how the contract between them is written and ENFORCED. Three sides: the DESIGNER freezes an approved mockup into a canonical oracle (oracle-manifest.json + baseline renders + a region/element inventory + token parity + a four-part visual acceptance contract); the FRONTEND dev consumes that contract and PORTS the…

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

TASKLANG
TYPE SKILL

IDENTITY "Designer ↔ Frontend Contract (universal — any stack)"
  > ONE skill = the WHOLE collaboration between the web designer and the frontend dev:
  > what each side PRODUCES for the other, where the shared data is STORED, how they
  > COMMUNICATE (paths + committed artifacts, never chat blobs), and how the CONTRACT
  > between them is written and mechanically ENFORCED. The designer freezes the approved
  > mockup into an ORACLE; the frontend PORTS it 1:1 and self-gates; the independent
  > design-diff VERIFIES the running UI against the oracle and feeds the pipeline's
  > verify gate. TECH-AGNOSTIC by construction: no framework, port, template language,
  > or product fact lives here — those are read from `docs/project_config/info.md`
  > (`{config.frontend_runtime}` + `{config.spec_path}`) at runtime.
  > It exists because builds without this contract silently re-style, drop whole page
  > regions, and ship broken UI that a green HTTP-200 smoke never catches.

How to install

The exact contents, by fingerprint
mdr add endorphin-ai/hasbrains-agent-kit/designer-frontend-contract@sha256:842086e98865a8a1

The line at the top of this page pins the label git:20260731.4cba6d1, 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.
