# BTW Side Questions
|
|
|
|
`/btw` lets you ask a quick side question about the **current session** without
|
|
turning that question into normal conversation history.
|
|
|
|
It is modeled after Claude Code's `/btw` behavior, but adapted to OpenClaw's
|
|
Gateway and multi-channel architecture.
|
|
|
|
## What it does
|
|
|
|
When you send:
|
|
|
|
```text
|
|
/btw what changed?
|
|
```
|
|
|
|
OpenClaw:
|
|
|
|
1. snapshots the current session context,
|
|
2. runs a separate **tool-less** model call,
|
|
3. answers only the side question,
|
|
4. leaves the main run alone,
|
|
5. does **not** write the BTW question or answer to session history,
|
|
6. emits the answer as a **live side result** rather than a normal assistant message.
|
|
|
|
The important mental model is:
|
|
|
|
- same session context
|
|
- separate one-shot side query
|
|
- no tool calls
|
|
- no future context pollution
|
|
- no transcript persistence
|
|
|
|
## What it does not do
|
|
|
|
`/btw` does **not**:
|
|
|
|
- create a new durable session,
|
|
- continue the unfinished main task,
|
|
- run tools or agent tool loops,
|
|
- write BTW question/answer data to transcript history,
|
|
- appear in `chat.history`,
|
|
- survive a reload.
|
|
|
|
It is intentionally **ephemeral**.
|
|
|
|
## How context works
|
|
|
|
BTW uses the current session as **background context only**.
|
|
|
|
If the main run is currently active, OpenClaw snapshots the current message
|
|
state and includes the in-flight main prompt as background context, while
|
|
explicitly telling the model:
|
|
|
|
- answer only the side question,
|
|
- do not resume or complete the unfinished main task,
|
|
- do not emit tool calls or pseudo-tool calls.
|
|
|
|
That keeps BTW isolated from the main run while still making it aware of what
|
|
the session is about.
|
|
|
|
## Delivery model
|
|
|
|
BTW is **not** delivered as a normal assistant transcript message.
|
|
|
|
At the Gateway protocol level:
|
|
|
|
- normal assistant chat uses the `chat` event
|
|
- BTW uses the `chat.side_result` event
|
|
|
|
This separation is intentional. If BTW reused the normal `chat` event path,
|
|
clients would treat it like regular conversation history.
|
|
|
|
Because BTW uses a separate live event and is not replayed from
|
|
`chat.history`, it disappears after reload.
|
|
|
|
## Surface behavior
|
|
|
|
### TUI
|
|
|
|
In TUI, BTW is rendered inline in the current session view, but it remains
|
|
ephemeral:
|
|
|
|
- visibly distinct from a normal assistant reply
|
|
- dismissible with `Enter` or `Esc`
|
|
- not replayed on reload
|
|
|
|
### External channels
|
|
|
|
On channels like Telegram, WhatsApp, and Discord, BTW is delivered as a
|
|
clearly labeled one-off reply because those surfaces do not have a local
|
|
ephemeral overlay concept.
|
|
|
|
The answer is still treated as a side result, not normal session history.
|
|
|
|
### Control UI / web
|
|
|
|
The Gateway emits BTW correctly as `chat.side_result`, and BTW is not included
|
|
in `chat.history`, so the persistence contract is already correct for web.
|
|
|
|
The current Control UI still needs a dedicated `chat.side_result` consumer to
|
|
render BTW live in the browser. Until that client-side support lands, BTW is a
|
|
Gateway-level feature with full TUI and external-channel behavior, but not yet
|
|
a complete browser UX.
|
|
|
|
## When to use BTW
|
|
|
|
Use `/btw` when you want:
|
|
|
|
- a quick clarification about the current work,
|
|
- a factual side answer while a long run is still in progress,
|
|
- a temporary answer that should not become part of future session context.
|
|
|
|
Examples:
|
|
|
|
```text
|
|
/btw what file are we editing?
|
|
/btw what does this error mean?
|
|
/btw summarize the current task in one sentence
|
|
/btw what is 17 * 19?
|
|
```
|
|
|
|
## When not to use BTW
|
|
|
|
Do not use `/btw` when you want the answer to become part of the session's
|
|
future working context.
|
|
|
|
In that case, ask normally in the main session instead of using BTW.
