/spec — Feature Specification

Trigger

/spec --issue N [--fast]

• --issue N — required. Reads GitHub issue #N.
• --fast — skip questions, apply defaults from reference/defaults.md, still requires user approval of the spec (hard gate).

Output

docs/specs/YYYY-MM-DD-{slug}-issue-{N}.md

YAML frontmatter includes issue: N so /implementation --issue N finds this file automatically.
