patterns-established:
  - "Auto-generation from bible: extract tags by priority, present with source attribution, let user adjust"
  - "Section emotional role cross-referencing: consult template for section role, cross with artist style for tag selection"

# Phase 7 Plan 01: Track Enrichment - Style Prompt and Delivery Tags Summary

**Automated 7-step style prompt extraction from artist bible and per-section delivery vocal suggestion engine with 3-family mapping table**

## Performance

- **Duration:** 3 min
- **Started:** 2026-04-10T22:49:16Z
- **Completed:** 2026-04-10T22:52:29Z
- **Tasks:** 2
- **Files modified:** 1

## Accomplishments
- Replaced manual 5-tier style prompt composition table with automated 7-step extraction procedure targeting 5-8 tags in 120-300 char sweet spot
- Replaced basic "Placement basique" delivery tag instruction with structured per-section suggestion engine featuring 6-row x 3-column mapping table
- Added source attribution presentation so users see where each auto-generated tag comes from
- Established 5 strict delivery rules including mandatory chorus > verse intensity and bridge contrast

## Task Commits

Each task was committed atomically:

1. **Task 1: Replace manual style prompt with 7-step auto-generation** - `441c81e` (feat)
2. **Task 2: Add per-section delivery vocal suggestion engine** - `58babf2` (feat)

## Files Created/Modified
- `.claude/skills/create-track/steps/02-structure-and-write.md` - Updated with auto-generation style prompt procedure and per-section delivery vocal suggestion engine

## Decisions Made
- Auto-generation targets 5-8 descriptive tags and 120-300 chars -- tighter than format.md's manual guidance (8-15 tags / 200-500 chars) because auto-generation produces more focused, higher-quality tag sets
- Delivery mapping table uses 3 broad artist style families rather than per-technique granularity -- covers the vast majority of use cases while remaining scannable
- Bible's "Techniques preferees" field explicitly overrides the mapping table when present -- respects artist-specific vocal instructions over generic mappings

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- Step 02 now has both enrichments (TRACK-03 style prompt auto-gen + TRACK-04 delivery metatag suggestions)
- Ready for 07-02 which integrates verification procedures into the track production workflow
- No blockers
