 ### GrepAI (Semantic Code Search)
 
-**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/`.
+**Recall hierarchy — wiki first, GrepAI second.** GrepAI is NOT the first stop for context.
+The synthesized **wiki** (`wiki/`, 57 curated client/project/system articles) is the truth layer
+for a *known entity* — check it first (it is cheaper and already distilled). Go to GrepAI when the
+wiki can't answer:
+
+1. **Code** — `grepai_search` / `grepai_trace_callers` / `grepai_trace_callees` over the Rust+TS
+   corpus (~8k files). The wiki has zero code awareness; this is GrepAI's irreplaceable value for
+   GuruRMM/GuruConnect dev (call-graph tracing, "where is Z implemented").
+2. **Discovery** — you don't know the entity name, or no wiki article exists yet (a new
+   client/system not yet compiled).
+3. **Sub-synthesis detail** — a fact that was in a raw session log but didn't make the wiki's
+   summary cut.
+
+Order of recall: **wiki (known entity) -> GrepAI (code / discovery / un-compiled detail) -> raw
+file reads.** Do NOT GrepAI something the wiki already answers — that's the redundant overlap.
 
-- **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:** `$CLAUDETOOLS_ROOT/grepai search "query" --json -c -n 5`
 - **Watcher:** runs as scheduled task "GrepAI Watcher - claudetools" (auto-starts on login, keeps index current)
