SKILL.md
The user has passed (or will pass) a markdown file of raw material. Treat it as the input pile, anything from a tidy list of fragments to a wall of unstructured prose to a transcript. The format does not matter. Read it end-to-end before doing anything else.
Then run a shaping session that produces a separate article document. This is exploit: the exploring is done, the pile is fixed, commit to a structure and mine the pile to fill it. Do not edit the raw material file, it is read-only to this skill.
If the user did not say where to save the article, ask once and remember the path.
