Playground

Use this Skill to produce a bounded, verifiable Playground outcome. Preserve the user's chosen stack, source material, and authorization boundaries.

Read the SandBase API map only when the task genuinely needs an external data source or generative model.

Workflow

1. Inspect the available files, runtime, versions, inputs, and existing conventions before deciding what to change.
2. Restate the requested outcome, constraints, acceptance checks, and any assumption that could change the result.
3. Produce the smallest complete implementation, analysis, or artifact that satisfies those checks.
4. Verify the real output with appropriate tests, previews, calculations, or source comparison; do not infer success from file creation alone.
5. Return the deliverable, evidence of validation, material assumptions, and unresolved limitations.

Quality gates

• Confirm canvas or frame dimensions, output format, timing, interaction, target runtime, and accessibility requirements.
• Preserve the existing design system and implementation stack; use named tokens and reusable structures instead of unexplained one-off values.
• Render or preview the real output, inspect representative states and breakpoints, and fix clipping, overlap, contrast, motion, or performance defects.
