## Key Design Patterns Across Ecosystem

### Pattern 1: Delta Tracking
Most mature projects (Ar9av/obsidian-wiki) use a `.manifest.json` to track ingested sources — hash, timestamp, which pages produced. Re-ingest only processes changed/new files. Claude-obsidian currently has no delta tracking.

### Pattern 2: Multi-Depth Queries
rvk7895 implements 3 tiers: Quick (index only), Standard (wiki + web), Deep (parallel agents). Current claude-obsidian has one depth level in wiki-query.

### Pattern 3: Goal Cascade Integration
ballred's project connects personal productivity (daily/weekly reviews) with the knowledge base. No PKM projects do this today in claude-obsidian.

### Pattern 4: Auto-Commit Hooks
ballred uses PostToolUse hooks for auto-git-commit on every file change. This keeps the vault in version control automatically.

### Pattern 5: Multi-Agent Compatibility
Ar9av's setup.sh deploys skills to Claude Code + Cursor + Windsurf + Codex + Gemini CLI simultaneously. claude-obsidian is Claude Code only.

### Pattern 6: Hybrid Search
ekadetov uses qmd (BM25 + vector) instead of simple keyword/index search. Big quality improvement for large vaults.

### Pattern 7: Emerging Schema
Ar9av's wiki has no fixed structure upfront — it emerges from the content. Claude-obsidian has a predefined structure.

### Pattern 8: Vision Ingestion
Ar9av supports images/screenshots/whiteboards as ingestable sources (vision model required). Claude-obsidian has no image ingestion.

### Pattern 9: Output Formats
rvk7895 and ekadetov export to Marp slides and matplotlib charts. Claude-obsidian outputs only Markdown.

### Pattern 10: Vault Adoption
Both claudesidian and ballred/pkm can be adopted onto existing vaults without destroying structure. Claude-obsidian requires starting fresh.

## Notable Quotes / Signal

From rvk7895 README:
> "The LLM owns the wiki. You rarely edit it manually — just explore in Obsidian and keep feeding it raw data."

From Ar9av README:
> "You write skills once, every agent can use them."
> "The wiki schema isn't fixed upfront. It emerges from your sources."

From kepano/obsidian-skills (Obsidian creator):
> Uses exact Agent Skills specification format — validates that AgriciDaniel's approach is on spec.
