Verify Sources

If no pending tracks:

All tracks in [album] have been verified. No action needed.

If pending tracks exist, list them:

SOURCE VERIFICATION: [Album Title]
===================================

Tracks needing verification:
  1. [track-slug] — [track-title]
  2. [track-slug] — [track-title]
  ...

Total: X tracks pending verification

Step 3: Walk Through Each Track

For each pending track:

1. Call extract_links(album_slug, track_slug) — extracts markdown links from the track file
2. Call extract_links(album_slug, "SOURCES.md") — get the full citation list
3. Read RESEARCH.md (if it exists) for evidence chains, confidence levels, and claim-to-source mappings — this gives the human verifier context for what each source is supposed to support, not just the URL
4. Present sources to the user:

TRACK: [track-title]
--------------------
Sources referenced in this track:

  1. [Source Name](URL) — [brief description of what it supports]
  2. [Source Name](URL) — [brief description]
  ...

Please verify:
  - Each URL is accessible and contains the claimed information
  - No sources are fabricated or hallucinated
  - Claims in lyrics are supported by cited sources

Type "verified" to confirm, or describe any issues.

4. Wait for user response:
   • If "verified" (or equivalent affirmative) → update the track
   • If issues reported → note them, ask user how to proceed

Step 4: Update Track Files

When user confirms verification for a track:

1. Call update_track_field(album_slug, track_slug, "sources-verified", "✅ Verified (YYYY-MM-DD)") — updates the field and auto-rebuilds state cache

   • Use today's date

2. Confirm the update:

✅ [track-title] — Sources verified (2025-02-06)

3. Move to next pending track

Step 5: Update Album Status (Auto-Advance)

After processing all tracks, check if the album status should advance:

1. Call get_album_progress(album_slug) — check how many tracks are now verified

2. If ALL tracks are verified (no more pending):

   • Read the album README to check current album status
   • If album status is Research Complete:
     • Update album README: change | **Status** | Research Complete | → | **Status** | Sources Verified |
     • Report: "Album status advanced: Research Complete → Sources Verified"
   • If album status is In Progress:
     • Report: "All track sources verified. Album status stays In Progress (already past research phase)."

3. If some tracks still pending:

   • Report how many remain and which ones

4. Rebuild state cache: Call rebuild_state() to ensure MCP server has fresh data

5. Summary report:

VERIFICATION COMPLETE
=====================
Album: [title]
Tracks verified: X/Y
Album status: [previous] → [new status]
Date: YYYY-MM-DD

All sources verified. This album is cleared for lyric writing.
Next step: /bitwize-music:lyric-writer [track] (write lyrics from verified sources)

Partial verification report (if some tracks still pending):

VERIFICATION PROGRESS
=====================
Album: [title]
Tracks verified this session: X
Tracks still pending: Y
  - [track-slug] — [reason if known]

Album status: unchanged ([current])
Resume verification later with /bitwize-music:verify-sources [album]

Handling Issues

If the user reports a problem with a source:

1. Document the issue in the track file as a comment or note
2. Do NOT mark as verified — keep status as Pending
3. Suggest resolution:
   • Source URL broken → "Can you find an updated URL?"
   • Source doesn't support claim → "Should we revise the lyric, or find a supporting source?"
   • Source is fabricated → "I'll remove this source. Do we need to revise the track?"
4. After resolution, re-present for verification

Remember

• Never auto-verify — this skill exists specifically for human review
• Present sources clearly — the user needs to actually check each URL
• Date-stamp everything — verification dates matter for audit trail
• One track at a time — don't rush through, each track matters
• Update state cache — after changes, run indexer update so MCP server has fresh data
