 <Tip>
 Be specific. Good instructions help Strix prioritize the most valuable attack paths.
 </Tip>
-
-## Workspace files
-
-Instructions become part of the prompt. To give Strix a file to work with, such
-as a wordlist, an API specification, or notes, use `--workspace-file`. Strix
-places the file into the sandbox workspace before the scan starts.
-
-```bash
-strix --target https://app.com --workspace-file ./wordlist.txt
-```
-
-The file lands at `/workspace/<file name>`. To choose the destination, write
-`PATH:DEST`. `DEST` is a path inside `/workspace`.
-
-```bash
-strix --target https://app.com \
-  --workspace-file ./openapi.yaml:specs/openapi.yaml \
-  --workspace-file ./notes.md
-```
-
-Repeat the option for every file you want to place. Strix lists the files in the
-agent task, so the agent knows where to read them.
-
-Rules that apply to every workspace file:
-
- The file is read-only inside the sandbox.
- The destination must stay inside `/workspace`.
- The destination must not fall inside a target directory, because target files
-  come from the target itself. Strix skips such a file and logs a warning.
- Two files cannot claim the same destination.
-
-<Note>
-A workspace file is data for the agent to use. It is not a scan target, and its
-contents do not change the instructions.
-</Note>
-
-<Warning>
-Do not place secrets in a workspace file. The sandbox runs untrusted target
-code, so treat anything you place there as readable by the target.
-</Warning>

  - To end the whole engagement, call the lifecycle tool: finish_scan (root) or agent_finish (subagent).
  - A turn that ends with plain text and no tool call does NOT stop you: the system nudges you to continue and will re-run you. Do not rely on going silent to pause — it will not pause you.
 - Answering a user question: put the answer in respond_to_user's message. Do not write the answer as plain text and then fall silent — that does not reach a stopping point, it just triggers a continuation nudge.
- If all you want to do is reply and stop, that whole turn is ONE respond_to_user call carrying the answer. Do not write the answer as text and then call respond_to_user as well: the user reads it twice.
- If you do end a turn on plain text and the nudge arrives, your words already reached the user. Do not restate them: call respond_to_user with NO message to simply wait, or with only whatever you still need to add.
 - You may include brief explanatory text before a tool call, and you can narrate while you work — plain text is shown to the user as you go. Narrating is free; respond_to_user is specifically the act of WAITING for the user, so do not call it just to give a status update.
 - Respond naturally when the user asks questions or gives instructions.
 - While actively working on a task, every turn should carry exactly one tool call — use think to plan, the appropriate tool to act, and respond_to_user only when you genuinely need the user.

 AGENT ISOLATION & SANDBOXING:
 - All agents run in the same shared Docker container for efficiency
- Each agent has its own terminal sessions
- Browsers are NOT per-agent by default: `agent-browser` with no `--session` is one
-  shared browser, so a concurrent agent's navigation invalidates your page and refs.
-  Pass `--session <your-agent-name>` for any browser work of your own — then it is
-  yours alone. Each session is a full Chromium (~340 MB) on this shared box, so keep
-  one, not several, and `agent-browser --session <name> close` when you're done with
-  the target; an idle browser is reclaimed automatically after 3 minutes
+- Each agent has its own: browser sessions, terminal sessions
 - All agents share the same /workspace directory and proxy history
 - Agents can see each other's files and proxy traffic for better collaboration
