Search all knowledge stores for: $ARGUMENTS

## Workflow

### Phase 1: Parallel Search (Observe)

Execute all searches in parallel:

1. **MEMORY.md**: Search the auto memory file at `.Codex/projects/*/memory/MEMORY.md` for the query terms using Grep
2. **Thoughtbox Knowledge Graph**: Use ToolSearch to load `thoughtbox_execute`, then search entities and observations matching the query via `tb.knowledge.listEntities({ name_pattern: "..." })` and `tb.knowledge.queryGraph(...)`
3. **Git History**: Run `git log --all --oneline --grep="$ARGUMENTS" -20` for commit history
4. **Assumption Registry**: Search `.assumptions/*.jsonl` for matching assumption records using Grep
5. **DGM Patterns**: Search `.dgm/fitness.json` for patterns matching the query using Grep
6. **Session Handoffs**: Search `.sessions/handoff-*.json` for relevant context using Grep

### Phase 2: Collate and Rank (Orient)

For each result found:
1. Note the **source store** (provenance)
2. Note the **freshness** (when was this last updated/verified)
3. Note the **relevance** (how closely does it match the query)
4. Check for **cross-references** (does this result reference other stores)

### Phase 3: Present Results (Act)

Present results grouped by relevance, with provenance:

```
## Knowledge Query: "{query}"

### High Relevance
- [MEMORY.md] {finding} (line {N}, updated {date})
- [Thoughtbox] Entity: {name} — {observation} (created {date})

### Medium Relevance
- [Git] {commit-hash}: {message} ({date})

### Low Relevance
- [Assumptions] {assumption} (confidence: {N}%, last verified: {date})

### Cross-References
- Thoughtbox entity "{name}" relates to git commit {hash}

### Gaps
- No results found in: {store1}, {store2}
- Consider adding knowledge about "{query}" to {suggested_store}
```

## Notes

- If a store doesn't exist yet (e.g., `.dgm/fitness.json` not created), skip it silently
- If Thoughtbox MCP tools aren't available, skip the knowledge graph search
- Always show which stores were searched and which returned nothing — gaps are informative
- If the query is broad, suggest more specific sub-queries
