Buildable Web Builder Skill

Use this skill to generate or adapt local web prototypes.

Resolve all referenced paths from the Buildable plugin or repository root.

Activation

Use only when the user is building or adapting a web app/prototype. Do not activate for unrelated frontend debugging unless the user asks for Buildable guidance.

Reference Loading Contract

Mandatory order:

1. Read the saved planner output first: .buildable/phase-plan.json when present, otherwise buildable-app-spec.json. Use .buildable/phase-plan.toon when present as the compact agent-facing build contract.
2. Load only appSpec.references.
3. Load current project files only as needed for the requested change.
4. Do not load all templates.
5. Load starter source only for the selected template and only when generating or editing it.

Default Stack

• Next.js
• TypeScript
• Tailwind CSS
• shadcn-style component patterns
• local/mock data

Workflow

1. Read the saved plan/app spec from the planner handoff.
2. Check appSpec.planAudit.checks before editing; treat blocked/failed checks as gates, not suggestions.
3. If questionsNeeded is true, ask the user before generating.
4. For fresh starts, prefer buildable generate "<prompt>" when a runnable template exists. Add --out <dir> only when the user requested a specific folder.
5. Apply appSpec.designSystem for visual tone, density, palette intent, layout rules, component rules, accessibility, and anti-patterns.
6. Apply appSpec.blocks as reusable micro-template guidance. Selected block docs are references to adapt to the current entity/design system, not generic code to paste blindly.
7. If appSpec.auth.requested is true, implement the local/mock auth shape first and keep any named provider behind the auth seam.
8. Load only the references listed in the app spec.
9. If the template is generic-app, use the selected archetype reference to shape screens and entities instead of loading unrelated templates.
10. Inspect the local project if generating inside an existing app.
11. Generate or adapt a complete first-screen prototype.
12. Keep data local unless the spec explicitly requires otherwise.
13. Run build/typecheck/lint checks when available.

Build Order

1. Create typed entities and sample data.
2. Build the primary screen and state operations.
3. Add empty, filtered, and edited states.
4. Apply responsive layout rules.
5. Review against the selected quality rubric.

Guardrails

• Do not add auth, accounts, billing, cloud previews, managed databases, telemetry, or deployment.
• Do not create marketing landing pages for app requests.
• Do not leave generic placeholder UI.
