prototype

# Prototype Build a throwaway prototype that answers named unknowns, operate it, and hand it to the user for judgment. ## Step 1: Name What the Prototype Must Settle Take the open unknowns from what was passed in. When nothing was passed in, derive them from the current work: the questions whose answers in prose would still leave the user guessing, such as what a surface looks like or whether an interaction pattern makes sense in the hand. State each unknown as a question the user answers by using the prototype rather than by reading a description. Output that list as text before building, and keep anything outside it out of the prototype. ## Step 2: Resolve the Prototype Path Reuse the slug of the plan that governs the work when there is one. Honor an explicit slug or output path the user passed in. Otherwise generate a slug from the task title: - Lowercase - Replace non-alphanumeric characters with hyphens - Collapse consecutive hyphens - Trim leading and trailing hyphens - Truncate to 40 characters at a word boundary Write to `.turbo/prototypes/<slug>.html`, creating the directory when it does not exist. State the resolved path before writing. Later rounds of the same prototype rewrite that same file. When the path holds a prototype of a different subject, append `-2`, `-3`, and so on until the path is free. ## Step 3: Build It Write one self-contained `.html` file at the resolved path, with markup, styles, script, and sample data inline. It runs from `file://` w...
