Skill: Discover Document Norms

Purpose

Help users define their project-specific artifact norms (paths, naming, lifecycle) for document governance. Projects may have their own documentation structure; this skill discovers and formalizes it so other skills (capture-work-items, brainstorm-design, assess-doc-readiness) can follow project norms.

Core Objective

Primary Goal: Produce docs/ARTIFACT_NORMS.md (and optionally .ai-cortex/artifact-norms.yaml) that declares the project's artifact paths, naming, and lifecycle for backlog, design, ADR, and calibration artifacts.

Success Criteria (ALL must be met):

1. ✅ Project structure scanned: Existing docs/ structure and conventions inspected
2. ✅ User preferences confirmed: Paths for backlog, design, adr, doc-readiness confirmed via dialogue (or accepted from starting template)
3. ✅ ARTIFACT_NORMS.md written: Human-readable norms file at docs/ARTIFACT_NORMS.md
4. ✅ Optional YAML created: If user requests, .ai-cortex/artifact-norms.yaml written with machine-readable schema
5. ✅ User confirmed: User explicitly approved the norms before final write
