prepare-prompt SKILL.md skillA
prepare-prompt from w1ne/kernelcad-web is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Turn a vague user ask into a Real Object Brief before writing any geometry. The brief is the contract that all downstream sub-skills work from.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# prepare-prompt ## Purpose A vague ask — "a wayfarer-style frame", "that bottle", "make the same one" — produces vague geometry. This sub-skill produces a **Real Object Brief**: a structured, numbered record of everything the reference communicates before any tool call touches the kernel. The brief is written as a `// Real Object Brief` block at the top of the `.kcad.ts` file, before any `param()` or geometry. It is the source of truth for the entire build. Every downstream sub-skill reads from it. ## Inputs - The user's ask (text, photo path, or both). - The reference photo(s) — can be one image showing one view, or several showing different angles. More views = fewer hidden-side guesses. ## Output A filled-in `// Real Object Brief` comment block, plus a list of open questions if any critical fact (scale, material, hidden side) cannot be inferred. ## The Real Object Brief format Required sections, in this order: ```ts // Real Object Brief // Artifact: <human name> — <one-line description of what it is>. // Reference: <relative path to the photo>. // Scale: millimetres. <key dimension 1: name ~N mm>, <key dimension 2: name ~N mm>, …

How to install
mdr add w1ne/kernelcad-web/prepare-prompt@sha256:4baf255e62b717e7The line at the top of this page pins the label git:20260516.e6b55a8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
