SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Turning an approved design or architecture spec into working code often means re-deciding things that were already settled, inventing load bearing choices mid build, and losing track of progress across sessions. This Skill gates every build on a recorded spec, then implements the feature (UI, backend logic, or both) following the project's own conventions, and updates the scope tracker when done. ## Core Features & Use Cases - Spec gate before building: Stops and routes to the architect step when a load bearing decision (auth provider, data model, page design) is unrecorded, or records it as an Assumed spec so the decision lives in the repo. - Dual build tracks: A UI track that enforces a professional design bar, design tokens, responsive layout, and WCAG accessibility, plus a logical track covering data layers, APIs, services, integrations, and migrations. - Scope and spec lifecycle tracking: Advances feature status in scope files, mirrors spec status from Proposed to Accepted, and emits verify steps tied to acceptance criteria. - Use Case: After running /architect to decide on a session based auth approach, run /develop to build the sign in pages and session logic, with the migration applied, tokens enforced, and the scope marked in progress. ## Quick Start Ask the agent to run /develop for a feature that already has an approved spec, for example build the accounts sign in feature from its spec.

FAQPage Schema
How do I build a feature from an approved spec?▼

Run /develop with the feature name after its spec exists. The skill reads the spec's requirements, design, and build plan, checks the nearest AGENTS.md conventions, then implements the UI or logic track and ticks off build plan tasks as they land.

What happens when no spec exists for a feature?▼

The Step 0 gate stops the build and asks how to proceed: route to /architect to deliberate the decision first, build directly if no real decision is involved, or record an Assumed spec capturing the owed decision before building.

Does the develop skill support both UI and backend work?▼

Yes, it classifies each task as UI, Logical, or both. UI builds follow design tokens, responsive layout, and an accessibility checklist; logical builds cover data layers, services, APIs, integrations, and migrations.

Can I use this skill in a monorepo?▼

Yes, it detects workspaces from manifests and operates inside the target package: its nested AGENTS.md, its own package scripts, and its scope file under docs/scope/<workspace>/.

Why does the build stop with a spec gap warning?▼

The completeness check found a missing load bearing section, such as a data model, API surface, or an unnamed source for a required value. You must update the spec via /architect or provide the answer so it is persisted before coding continues.

When should I not use the develop skill?▼

Do not use it to make architecture decisions, write spec rationale, or restructure AGENTS.md; those belong to /architect, /audit, and /sync. It also will not run verification or tests, which are handled by /check verify and /test.
