+description: Bulk-index code or docs into the active EEMS
+---
+
+The user invoked `/index` with arguments: `$ARGUMENTS`
+
+Expected forms:
+- `/index status [project]` → call `index_status` (with optional project
+  filter). Paste the returned string verbatim.
+- `/index clear <code|docs|all> [project]` → call `index_clear` with the given
+  kind + optional project. Report one line: `cleared: code=<N>, docs=<N>`.
+- `/index code <root_path> [project] [extensions]` → call `index_code`. If
+  `project` is omitted, derive it from the basename of `root_path`. If `extensions` is
+  omitted, leave it unset (sane defaults kick in). Report two lines:
+  ```
+  indexed <files_indexed>/<files_seen> files (skipped <files_skipped>)
+  chunks: <chunks_inserted> inserted, <chunks_embedded> embedded, <embed_failures> embed failures
+  ```
+- `/index docs <root_path> [project]` → call `index_docs`. Project derivation
+  same as above. Same two-line report shape.
+
+Rules:
+- If you derived `project` from the path, echo it as `(project=<name>)` on its own line.
+- No narration. No "I will...".
+- If `$ARGUMENTS` is empty or starts with `help`, list the four forms above and stop.
