computer_use kept its own approval decision: two module dicts
(_session_auto_approve / _always_allow) mirroring tools.approval's
session store and _persist_choice, a private verdict vocabulary
(approve_once/approve_session/always_approve) that hermes_cli mapped
back to once/session/always, and — the real problem — `if
_approval_callback is None: return None`. Only the interactive CLI ever
installed that callback, so every other host (gateway turns, cron,
api_server, tui_gateway, ACP) ran destructive desktop input with no
approval at all, ignoring cron_mode / unattended_mode / the permanent
allowlist, and "always" grants were invisible to `is_approved`,
`clear_session` and the messaging-platform approval buttons.
_request_approval now calls tools.approval._run_approval_gate with
pattern_key `cua:<action>:<background|foreground>` (the old scope shape,
so a background grant still never covers the visible foreground variant)
and fail_closed_when_no_human=True, the same posture as
request_tool_approval / the SSH-config write gate. The private dicts,
their release/atexit clearing, the verdict mapping in
hermes_cli/cli_modal_mixin.py and the extra callback install in cli.py
are deleted: the CLI's terminal_tool callback answers computer_use
prompts like any other tool. set_approval_callback stays as an optional
explicit-callback hook with the shared callback contract
(cb(command, description, **kw) -> once|session|always|deny|timeout);
no in-tree host uses it.
Behavior change:
- No approval callback and no gateway (cron, api_server/webhook,
headless -q, plain library use): destructive actions are now REFUSED
with a BLOCKED error and never reach the backend. Previously they
silently ran. cron honors approvals.cron_mode, unattended platforms
approvals.unattended_mode, -q approvals.single_query_mode.
- --yolo / gateway /yolo / approvals.mode: off still allow (unchanged).
- Gateway sessions (Telegram/Discord/Slack/...) now get a real pending
approval with once/session/always buttons instead of default-allow.
- session/always grants live in tools.approval's store; "always" is one
command_allowlist entry (`cua:click:background`) and is scoped to that
action+mode — the old blanket "always_approve unlocks everything for
the session" no longer exists.
- Denial wording is the shared gate's ("BLOCKED: User denied ...",
"BLOCKED: Action timed out ..."); the error JSON keeps `action`.
Tests: tests/tools/test_computer_use_approval_isolation.py
::test_no_callback_refuses_unless_yolo (blocked + no backend call, then
yolo executes) and ::test_always_grant_lands_in_the_shared_store
(is_approved sees the cua:<action>:<mode> key; second call served from
the store). Sabotage: restoring the `callback is None -> allow`
short-circuit fails the first; swapping the shared gate for a private
grant set fails the second plus the three delivery-ladder scope tests.
tests/tools/conftest.py gains `grant_computer_use_approvals` for
dispatch tests that only care about routing.
Website
This website is built using Docusaurus, a modern static website generator.
Installation
yarn
Local Development
yarn start
This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.
Build
yarn build
This command generates static content into the build directory and can be served using any static contents hosting service.
Deployment
Using SSH:
USE_SSH=true yarn deploy
Not using SSH:
GIT_USER=<Your GitHub username> yarn deploy
If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the gh-pages branch.
Diagram Linting
CI runs ascii-guard to lint docs for ASCII box diagrams. Use Mermaid (````mermaid`) or plain lists/tables instead of ASCII boxes to avoid CI failures.
