- description: >-

- Search inside past agent sessions and continue the one that matters with a single command.

- Uses a separate episodic session index, so raw chat noise never pollutes the curated RAG.

- Triggers: "/chat-search", "which chat discussed X", "did we already research X", "search old

- chats".

- # /chat-search — the book of chats (search inside old sessions)

- A thin wrapper over `$IMPORTS_ROOT/chat_search.py`. Do NOT reimplement the logic — call the engine and show the result.

- ## When

- - "which chat did we discuss X in?", "have we already looked into this?", "find the old conversation about X".

- - Before starting a new topic — check whether it was already dug into (the twin of RECALL).

- ## What it is (and what it is NOT)

- - It searches a **separate** session index `_brain_sessions.npy` (21k+ chunks from `_session-md\<machine>\<cli>.md`), built by `brain_sessions_index.py`.

- - It is **NOT** the essence index behind `/ask`: raw chats are deliberately excluded from the sharp "mind" (the essence/evidence decision, 2026-06-26). This is the evidence layer — "where exactly it was discussed" — while `/ask` answers "what I think".

- - HUMAN chats only: service/robot sessions are filtered out at export time (a classifier + a cheap-model judge).

- ## How to run

- python "$IMPORTS_ROOT/chat_search.py" "query in your own words"

- python "$IMPORTS_ROOT/chat_search.py" --machine LAPTOP-1 "query" # one machine only

- python "$IMPORTS_ROOT/chat_search.py" -n 8 "query" # top-N (default 10)

- Every hit: `[rr=score] date · machine · topic` + a snippet + the line `▶ continue: python continue_session.py <cli>`.

-

- ## Continue a chat you found

- Copy the command from the hit (or use `/resume-last` for the most recent one). `continue_session.py <cli>` assembles a seed of the old chat into the clipboard — paste it into a new session.

-

- ## Caveats (AK-47)

- - The index is built at night (`run_session_archive.local.cmd` → `brain_sessions_index.py`, incrementally). A fresh chat shows up after the nightly run; to force it: `python brain_sessions_index.py`.

- - Index missing / empty → the engine itself tells you `Run: python brain_sessions_index.py --full`.

- - Reranker scores can be negative — what matters is the ORDER (top-1 = most relevant), not the sign.

- - Siblings: `/ask` (meaning across the vault), `/search` (exact words in Telegram/FB/ChatGPT), `/resume-last` (continue the latest).
