caspar-prototype

name	caspar-prototype
description	Generate a single self-contained, clickable HTML prototype to make a feature visible before planning — resolving ambiguity pre-scope, validating flows pre-plan, or rendering an approved UX spec for stakeholder review. Triggers on "prototype this", "mock up the UI", "make a clickable preview", or a mid-flow `ux` Stage 1→2 transition. Do NOT trigger to write production app code, build a multi-file frontend, or plan/scope the work itself — this produces one throwaway HTML file only.
user-invocable	true

prototype

Produce one portable, self-contained HTML file that makes a feature visible before it is planned. Output saved to {OUT_DIR}/prototypes/{slug}_{MMDDYY}.html.

Inputs

• $ARGUMENTS (feature description, --explore flag, optional output path).
• Env markers: FROM_UX=true, FROM_KICKOFF=true.
• On-disk context (read FULLY, no offset/limit): docs/tasks/{branch}/concepts/scope.md, .../specs/prd.md, .../ux.md. Resolve branch via git rev-parse --abbrev-ref HEAD at runtime.

Mode + fidelity (detect most-context-first; this drives intake and faithfulness)
