Skill: /vault-lint

Weekly vault health scan — contradictions, orphans, missing Concept pages, and stale claims — output is a prioritized action list, not a report.

Don't: auto-fix anything — surface for Shane to decide. Don't use this for targeted note exploration — that's the obsidian skill.

Steps

1. Run the four scans below using obsidian CLI commands via bash
2. Collate results into a prioritized action list
3. Present findings grouped by category with specific file names and fix instructions
4. Do NOT auto-fix anything — surface for Shane to decide

Scan 1 — Contradictions between Concept pages

obsidian search query='Concepts/' limit=50

For each Concept page found, read it. Compare claims across pages. Flag pairs where one page asserts X and another asserts not-X (or a materially different position on the same topic).

Output format:

CONTRADICTION: Concepts/[A] vs Concepts/[B]
  [A] says: "[quote]"
  [B] says: "[quote]"
  → Resolve by: updating whichever is older or merging into a single page

Scan 2 — Orphan pages (no inbound links)

obsidian search query='[[' limit=100

Read each page that contains wiki-links and collect every [[linked page]] reference. Any Concept page that appears in zero link lists is an orphan.

Output format:

ORPHAN: Concepts/[page]
  Created: [date if available]
  → Link from a related note or delete if superseded

Scan 3 — Concepts mentioned 3+ times without a dedicated page

obsidian search query='TERM' limit=20

Run searches for noun phrases that appear frequently across the vault. Count mentions. Any term appearing 3+ times that does NOT have a matching file in Concepts/ is a gap.

Strategy: search for terms surfaced during recent /connect and /trace runs first; also scan Daily Notes for recurring nouns.

Output format:

MISSING CONCEPT: "[term]" (N mentions, no Concepts/[term] page)
  Seen in: [list of note names]
  → Create Concepts/[term] page

Scan 4 — Stale claims superseded by newer sources

obsidian search query='Clippings/' limit=30

For each Concept page, check if any claim is contradicted or significantly updated by a more recent Clipping. Look for:

• Dates cited in Concept pages that are older than 2 years
• Clippings that explicitly update or retract a prior claim
• Concepts referencing statistics or studies where a newer Clipping cites updated data

Output format:

STALE: Concepts/[page]
  Claim: "[quote from concept page]"
  Superseded by: Clippings/[newer source] ([date])
  → Update claim or add caveat in Concepts/[page]

Fallback (if qwen unavailable)

Execute all four scans directly using obsidian search and obsidian read commands via bash. Apply the same logic described above. The scans are bash-executable without Qwen.

Output structure

Present findings in this order, most actionable first:

1. Contradictions (fix these — they corrupt the knowledge base)
2. Missing Concepts (create these — reduces future orphan risk)
3. Orphans (link or delete)
4. Stale claims (update or caveat)

End with a one-line summary: "N issues found across Concepts/ — X contradictions, Y orphans, Z missing pages, W stale claims."
