connector: gate remote tool guidance on active permissions

Move the heavy remote-tool operating guidance out of the always-on tool prompts and inject it only when the current context can actually use those tools. - add extras prompts for computer_use_remote, code_execution_remote, and text_editor_remote - trim the base tool prompts down to the stable contract and minimal notes - inject detailed guidance from message-loop extensions instead of always paying the token cost - store remote_files and remote_exec hello metadata alongside computer_use metadata - make code_execution_remote follow the real F4 exec-enabled state - make text_editor_remote follow the real F3 read-only vs read-write state - surface read-only mode in the injected text-editor guidance and suppress write guidance there - keep legacy fallback behavior for older CLIs that do not yet advertise the new hello metadata

8 +- prompt patterns: `{{prompt_patterns}}`
9 +- dialog patterns: `{{dialog_patterns}}`
10 +
11 +- Use this tool for shell-backed execution on the remote CLI machine, not on the Agent Zero server.
12 +- Session ids are frontend-local and persistent across calls. Reuse the same `session` when continuing a workflow.
13 +- Use `runtime=terminal` for shell commands, `runtime=python` for Python snippets, and `runtime=nodejs` for Node.js snippets.
14 +- Use `runtime=output` to poll a running session after a prior call returned before the shell settled.
15 +- Use `runtime=reset` when a session is stuck or you need a clean shell.
16 +- `runtime=input` is only a deprecated compatibility alias for sending one line of keyboard input into a running shell session.
17 +- Frontend execution may still be locally disabled in the CLI session. If so, expect a structured `{ok: false}` error instead of a fallback runtime.
18 +- Prefer concise, self-checking commands. For multi-step work, inspect output and continue in the same session instead of restarting from scratch.

9 +- Use this for local desktop and native UI tasks on the connected machine.
10 +- If the task is browser-only and the user is flexible, prefer `browser_agent` because it is usually more reliable and token-efficient than screenshot-driven desktop control.
11 +- Use `start_session` before interactive desktop actions. `status` is for inspection; `stop_session` ends the session.
12 +- Base every decision on the latest screenshot or a definitive tool result, not memory.
13 +- Successful `start_session`, `move`, `click`, `scroll`, `key`, and `type` calls already attach a fresh screenshot.
14 +- Use `capture` only when you need a screen refresh without taking another action.
15 +- Prefer keyboard actions over pointer actions when there is a reliable keyboard path.
16 +- Treat menus and popups as transient UI. If a click dismisses one without visible progress, treat that attempt as failed and switch approach.
17 +- If the same approach has already failed twice without visible progress, stop repeating it and try a different strategy.
18 +- For browser work done through this tool, only claim success when the page content area visibly shows the expected destination or result.
19 +- Use `type(..., submit=true)` only for navigation-style entry such as an address bar or command box. For ordinary text fields, type first and send `enter` separately only if needed.
20 +- In `free_run`, do not expect a fresh approval prompt. If silent restore is no longer valid, expect `COMPUTER_USE_REARM_REQUIRED`.
21 +- Treat user interventions as high-priority control signals. If the user says `stop`, `pause`, `abort`, `hold`, `don't continue`, or equivalent, stop using computer-use tools until the user explicitly resumes.

3 Use the connected CLI host machine as a local desktop target.

5 -## Preferred Scope
6 -- Use this for local desktop and native UI tasks on the connected machine.
7 -- For ordinary website browsing, search, form filling, and web downloads, prefer `browser_agent`.
8 -- If the user is flexible and the task is browser-only, briefly guide them toward browser tools because they are usually more reliable and token-efficient than screenshot-driven computer use.
9 -- Before doing real computer-use work, load the `computer-use-remote` skill and follow it.
5 +This tool is only usable when the current context has a subscribed CLI with enabled local computer use.
6 +Detailed operating guidance is injected separately only when that condition is true, so the base system prompt stays small when computer use is not in play.
7
8 ## Requirements
9 - A CLI client must be connected to this context via the shared `/ws` namespace.
10 - The CLI must advertise `computer_use_remote` support and local computer use must be enabled there.
14 -- In `free_run`, do not expect a fresh approval prompt. If restore is no longer valid, the tool will surface `COMPUTER_USE_REARM_REQUIRED`.
15 -
16 -## Minimal Rules
17 -- Treat user interventions as high-priority control signals.
18 -- If the user says `stop`, `pause`, `abort`, `hold`, `don't continue`, or equivalent, halt immediately and do not use computer-use tools again until the user explicitly resumes.
19 -- Call `start_session` first. It automatically attaches the current screen.
20 -- Decide from the latest screenshot, not from memory.
21 -- Interactive actions (`move`, `click`, `scroll`, `key`, `type`) automatically attach a fresh screenshot after they run.
22 -- Use `capture` only when you need another screen refresh without taking an action.
23 -- Prefer keyboard actions over pointer actions whenever a reliable keyboard path exists.

3 This tool allows you to read, write, and patch files on the **remote machine where the CLI is running**.
4 This is different from `text_editor` which operates on the Agent Zero server's filesystem.

6 -Use `text_editor_remote` when the user asks you to edit files on their local machine while connected via the CLI.
5 +Detailed usage guidance is injected separately only when the current context has a
6 +subscribed CLI, so the base system prompt stays small when remote editing is not in play.

8 ## Requirements
9 - A CLI client must be connected to this context via the shared `/ws` namespace.
10 - The CLI client must have enabled remote file editing support.

12 ## Operations
13 -
14 -### Read a file
15 -```json
16 -{
17 - "tool_name": "text_editor_remote",
18 - "tool_args": {
19 - "op": "read",
20 - "path": "/path/on/remote/machine/file.py",
21 - "line_from": 1,
22 - "line_to": 50
23 - }
24 -}
25 -```
26 -Returns file content with line numbers. `line_from` and `line_to` are optional.
27 -
28 -### Write a file
29 -```json
30 -{
31 - "tool_name": "text_editor_remote",
32 - "tool_args": {
33 - "op": "write",
34 - "path": "/path/on/remote/machine/file.py",
35 - "content": "import os\nprint('hello')\n"
36 - }
37 -}
38 -```
39 -Creates or overwrites the file on the remote machine.
40 -
41 -### Patch a file
42 -```json
43 -{
44 - "tool_name": "text_editor_remote",
45 - "tool_args": {
46 - "op": "patch",
47 - "path": "/path/on/remote/machine/file.py",
48 - "edits": [
49 - {"from": 5, "to": 5, "content": " if x == 2:\n"}
50 - ]
51 - }
52 -}
53 -```
54 -Applies line-range patches to the file. Use the same format as the standard `text_editor:patch` tool.
13 +- `read`: optional `line_from`, `line_to`
14 +- `write`: requires `content`
15 +- `patch`: requires `edits`
16
17 ## Notes
57 -- Always read the file first before patching to get current line numbers.
18 - Paths are evaluated on the **remote machine's filesystem**, not the Agent Zero server.
59 -- If no CLI is connected, the tool will return an error message.
19 - The transport uses `connector_file_op` and `connector_file_op_result` with a shared `op_id`.
