Shadow Areas

Analytically scans a written artifact for gaps the author has not addressed. Unlike iterative Q&A clarification, this skill reads the existing material and emits a structured report: each gap carries a category from a locked 7-category taxonomy, a 3-tier severity, and a direct-question probe the author can act on immediately.

Actions

#	Action	Role	Input
01	detect	Parse input, extract gaps, classify category and severity, emit probes	file path or inline text
02	render-report	Render markdown grouped by category and sorted by severity, write report	gap list from detect
03	diff	Load prior report, classify gaps as closed / still-open / newly-introduced	gap list from detect + prior report path

Dispatch by context: with no prior report run detect then render-report; with one, run detect then diff. Before running an action, read its file in actions/, not only the table or assets.

Transversal rules

• Never modify the source artifact.
• Every gap carries all three: a category, a severity, and a probe question.
• Every probe is a direct question ending with ?.
• Categories and severities come from the locked sets in references/locked-sets.json.
• When zero blockers and zero majors remain, stamp the report status: clean.
• On re-runs, gaps are matched by category and snippet, never by question wording, so rephrasing a question never creates a spurious "newly introduced" gap.
