Port 2 plugin skills to Claude.ai Agent Skills

[chrispezza]

Re-scoped 2026-07-11. Original task ("extract patterns into Claude.ai skills once the Claude Code workflow is validated") is partly superseded: Claude.ai and Claude Code now share the Agent Skills format, and ADR 0011 made the plugin skills self-contained with bundled prompts. This is now a porting task, not an authoring task.

Scope

Port product-ideation and product-flow from plugin/skills/ to claude.ai-compatible skills in skills-claude-ai/. Skip tech-spec — it depends on subagent spawning and file-based artifact handoff that don't translate.

Runtime adaptations (the only intended deltas from the plugin versions):

• Bundle prompt files inside each skill dir; replace ${CLAUDE_PLUGIN_ROOT} with skill-relative paths
• Replace the .product-dev/ registry with a conversation-scoped artifact ledger + explicit product-dev-artifacts.md export (also bridges back to the plugin: sections drop into .product-dev/artifacts/)
• Package as upload-ready zips

Remaining

• Upload both zips via claude.ai → Settings → Capabilities → Skills
• Test the ideation flow across 2-3 real conversations; verify variable resolution from the ledger and the export/resume round-trip into product-flow
• Adjust SKILL.md wording based on what breaks

Original context: build skills from lived experience of which prompts get used — priorities 1-3 (#10, #11) shipped, workflow validated.

Ports refreshed to v0.5.0 (interrogation gates, candidate directions, optional placeholders, process-learnings in the export bundle) and the stale test-script reference fixed. Fresh upload zips are on your Desktop: product-ideation.zip and product-flow.zip. Remaining: upload via claude.ai → Settings → Capabilities → Skills, then the 2-3 conversation test drive.
