UI-first software development workflow for AI agents. Use when building apps UI-first, extracting specifications from existing prototypes, preparing backend implementation handoff from completed frontend components, or when asked to do "UI-driven development", "prototype-before-spec", "FE before BE", "extract contracts from UI", "slot map", "state map", or "backend contract map".
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
# UI-Driven Spec — FE-First Development Workflow ## Core Philosophy > **The UI is the user interaction map, not the supreme authority.** > **The supreme authority remains the Spec and System Architecture.** > **Human / Architect approval is mandatory before a single line of backend code is written.** - **Traditional flow:** `Spec → Backend → Frontend` (Gaps discovered late, expensive patches). - **UI-driven flow:** `UI Prototyping → Contract Extraction → Spec Alignment & Gate → Module-by-Module Backend Implementation & QA`. --- ## Iron Laws 1. **Extraction over invention**: Contract extraction reads from FE code and mock types without guessing. Missing information must be flagged as `[TBD]`, never self-filled. 2. **Spec judges artifacts, not the reverse**: If an artifact conflicts with the Spec, conform the artifact to the Spec. Do not alter the Spec during extraction. 3. **Owner Review Gate is non-negotiable**: No backend planning or implementation may begin without explicit owner sign-off. Silence is never approval. …

How to install
mdr add tamnguyendinh/anvien/ui-driven-spec@sha256:20aa3813495e98dfThe line at the top of this page pins the label git:20260830.9d72126, 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.
