skill-drafter now reads {catalog_root}/<slug>.md before writing its
draft and prepends a warning block to its confirmation output when
an existing skill would be overwritten during manual `mv` promotion.
The draft is still written to .drafts/<slug>.md — the check is a
hint, not a block.
Closes v2.3.0 dogfood finding (post_dogfood_findings[0]): the
drafter produced .drafts/hooks-pattern.md when an approved
hooks-pattern.md seed already existed, giving no signal that `mv`
during promotion would silently overwrite the seed. v2.3.1
introduced the qualified-slug mechanism to resolve such collisions;
v2.3.2 surfaces them at the right moment — before promotion.
Changes:
- agents/skill-drafter.md — new Step 2 between slug computation and
source reading. Reads {catalog_root}/<slug>.md, inspects
review_status, derives a kebab-case qualifier from the concept
handle (or source basename fallback). Subsequent steps renumbered
3→7. Output format gains Collision: field and optional warning
block. New Hard Rule.
- tests/fixtures/skill-drafter/slug-collision-expected.md — reference
fixture documenting expected confirmation shape across four
scenarios (no collision, approved collision, soft pending
collision, collision with no good qualifier). Skill-drafter is
prompt-driven; fixture anchors shape for human verification and
downstream parsers.
- CHANGELOG [2.3.2], plugin.json 2.3.1→2.3.2, README badge, plugin
CLAUDE.md slug-convention Collision-hint bullet, marketplace root
README summary, marketplace root CLAUDE.md plugin table.
Non-breaking. No frontmatter/drafts-layout/tool-scope/regex changes.
Existing pipelines see one extra field and an optional warning —
both purely additive.
