+## 1.1 AdvisoryAI Knowledge Search
+
+AKS commands expose deterministic retrieval from AdvisoryAI (`docs|api|doctor`) without requiring an LLM.
+
+### `stella search`
+
+```bash
+stella search "<query>" \
+  [--type docs|api|doctor] \
+  [--product <product>] \
+  [--version <version>] \
+  [--service <service>] \
+  [--tag <tag>] \
+  [--k <1-100>] \
+  [--json]
+```
+
+Notes:
+- `--type` and `--tag` are repeatable or comma-separated.
+- `--json` emits stable machine-readable payload with `results[].open`.
+
+### `stella doctor suggest`
+
+```bash
+stella doctor suggest "<symptom-or-error>" \
+  [--product <product>] \
+  [--version <version>] \
+  [--k <1-100>] \
+  [--json]
+```
+
+Uses the same AKS index and prints grouped recommendations for:
+- Doctor checks (with run command).
+- Related docs anchors.
+- Related API operations.
+
+### `stella advisoryai index rebuild`
+
+```bash
+stella advisoryai index rebuild [--json]
+```
+
+Rebuilds the deterministic AKS index from local markdown, OpenAPI, and Doctor metadata sources.
