 ### GrepAI (Semantic Code Search)
 
-Use for intent-based search ("how does auth work"), exploring unfamiliar code, context recovery.
-- **MCP tool:** `grepai` server tools
-- **Agent:** `deep-explore` agent
-- **CLI:** `grepai search "query" --json --compact`
+**Use GrepAI first for any context lookup before reading files directly.** It indexes all session logs, skill files, and project docs with boosted relevance for `.claude/` and `session-logs/`.
+
+- **When to use:** "what did we do with X", "how does Y work", "find where Z is configured", context recovery, exploring unfamiliar code
+- **MCP tools:** `grepai_search` (primary), `grepai_trace_callers`, `grepai_trace_callees`
+- **Agent:** `deep-explore` (for multi-hop exploration)
+- **CLI:** `D:/claudetools/grepai.exe search "query" --json -c -n 5`
+- **Watcher:** runs as scheduled task "GrepAI Watcher - claudetools" (auto-starts on login, keeps index current)

+### GrepAI config (re-apply on new machines)
+
+`.grepai/` is gitignored (90 MB index + machine-specific timestamps). After running `grepai init` on a new machine, apply these overrides to `.grepai/config.yaml`:
+
+**Remove the `.md` penalty** (markdown is primary content here, not docs noise):
+```yaml
+# DELETE this block:
+- pattern: .md
+  factor: 0.6
+```
+
+**Add these bonuses** under `search.boost.bonuses`:

 ### Warm-start and GrepAI
 
 GrepAI uses `nomic-embed-text` for context lookups, which keeps the Ollama **service** running continuously. The 30-50s service cold-start is effectively eliminated in normal workflow. `qwen3:14b` may take ~5s to swap into VRAM if it hasn't been called recently, but that's the worst case — not 50s.
