Third-party drivers (e.g. a Codex-style computer-use reimplementation) could
only replace cua-driver by patching core. computer_use now follows the
single-select provider model Hermes uses for memory providers, context
engines and cron schedulers:
- plugins/computer_use/__init__.py discovers bundled
plugins/computer_use/<name>/ then user $HERMES_HOME/plugins/<name>/
(marker: register_computer_use_provider / ComputerUseProvider) and loads
ONLY the provider computer_use.backend names (default "cua"), read per
call so each profile gets its own. Unselected providers are never
imported; listing reads plugin.yaml only. An unknown/unloadable name
returns an error naming it and the installed providers; no fallback.
- The built-in cua-driver is an ordinary bundled provider at
plugins/computer_use/cua/ (driver implementation stays in
tools/computer_use). tools/computer_use/backend.py gains
ComputerUseProvider (create_backend(permission_mode=...), is_available(),
optional doctor()).
- The tool's check_fn and backend construction go through the selected
provider; the model-facing schema is unchanged for every provider
(prompt-cache invariant). The test-only HERMES_COMPUTER_USE_BACKEND env
switch is gone (tests patch _new_backend).
- General plugin discovery treats computer-use providers as exclusive
(not eagerly imported, not listed as toggleable) and skips the bundled
computer_use/ category, same as memory/, context_engine/, cron_providers/.
- hermes tools and the Desktop toolset panel list installed providers next
to cua; computer-use doctor/status/permissions and the Desktop status
payload skip cua-driver/TCC probes when another provider is selected.
* refactor(plugins): remove the Sep 2026 decomposition compat layer on schedule
The PLUGIN-COMPAT layer (2776813df3 + d63e380324 + 0a5164cebe) kept pre-#102117 import paths
alive for external plugins until 2026-09-14. That window closed two weeks ago; since then the loader
has already been skipping plugins that use the old paths. This removes the layer itself:
- 328 appended `PLUGIN-COMPAT` blocks (lazy `__getattr__` pointer tables, re-exported third-party
names, restored dead definitions) and the three re-export stub modules
(gateway/startup_watchdog, hermes_cli/observability/relay_runtime, tools/environments/modal_utils)
- COMPAT_MANIFEST.md, compat_manifest.json, scripts/check_compat_pointers.py and its lint step
- the reporting surfaces: CLI banner notice, `hermes plugins compat`, the `hermes doctor` section,
the post-update notice, the Desktop one-time dialog, the loader's pre-import skip and the
`plugins.allow_deprecated_imports` escape hatch
An external plugin that still imports an old path now fails to load with its ImportError as the
reason in `hermes plugins list`, the same path as any broken plugin.
hermes_cli/plugin_compat.py stays as three inert stubs (compat_report, removal_in_effect,
summary_lines): an already-running pre-removal `hermes update` lazy-imports them after the checkout
swap (tests/compat/old_updater_surface.json).
In-tree fallout, both already dead: hermes_cli/setup.py::_check_espeak_ng (no callers; its
`shutil` came from a compat block) and gateway/config.py::SessionResetPolicy ("retained solely for
the scheduled plugin-compat window"). Two test_run_agent patches targeted the removed
`run_agent.handle_function_call` pointer; they now patch `model_tools.handle_function_call`, the
seam production reads, like every sibling test in that file.
* chore: retrigger CI (zero-job startup_failure phantom)
* test: drop resolution allowlist rows for the two deleted which() sites
hermes_cli/setup.py::_check_espeak_ng (dead) and tools/skillevaluator_scan.py::scanner_available
(a restored definition inside a PLUGIN-COMPAT block) no longer exist; the stale-row gate requires
their allowlist entries go with them.
The first cut appended the recovery only in `_tcc_row`, which is built by the
0.10 fallback probes. Drivers that serve health_report (0.22+, the ones a
stale row actually bites) render their own tcc_* rows untouched, so `doctor`
never showed it. Apply the hint at the report seam like the display-count
guard so both paths get it.
Also: one CUA_DRIVER_BUNDLE_ID (permissions.py is the leaf; the daemon
imports it), the CLI derives the field set from the same table, and the
unverified "--upgrade repairs stale rows" claim is dropped from hint + docs
(the user hitting this is already on a current driver).
`hermes computer-use permissions status` and the doctor's fallback `tcc_*`
rows told a user whose System Settings toggle already showed CuaDriver ON to
"grant it in System Settings" — the one step that cannot help. macOS keys the
TCC row to the app's code-signing requirement; a row written for an earlier
CuaDriver build stops matching after a driver update and flipping the toggle
does not rewrite it (trycua/cua#3170, repaired by the cua-driver >= 0.22
installer on update). The daemon then reports Accessibility / Screen Recording
false while the pane shows ON, and every click silently no-ops (#99732).
`permissions.stale_tcc_grant_hint(*missing)` renders the reset for exactly
the missing services (`tccutil reset Accessibility|ScreenCapture
com.trycua.driver`, then `hermes computer-use permissions grant`); both
surfaces append it only when a grant is actually reported False. Docs: the
computer-use page still said bounded/unrestricted daemons run "under the
Hermes host identity" — they launch through CuaDriver.app since #95381 — and
gains the stale-row troubleshooting entry.
The Sep 2026 decomposition (PR #102117) makes internal import paths a non-API: names now live in
the focused modules that define them. This commit is the ONLY thing keeping the old paths alive,
so external plugins have time to update. It is deliberately a single, unsquashed commit:
git revert <this sha>
removes every shim, stub and manifest at once on the announced date. Nothing in-tree may depend on
these pointers: scripts/check_compat_pointers.py (wired into lint.yml) fails CI if it does.
What it adds (see COMPAT_MANIFEST.md, compat_manifest.json):
- 332 facade modules get one delimited `PLUGIN-COMPAT` block appended at the end of the file
- 1,172 moved names resolved lazily via a module `__getattr__` (PEP 562) — never a top-level import,
so no import cycles; facades that already had `__getattr__` get a chained one
- 592 third-party/stdlib names the old modules used to expose, with their original import statements
- 266 public definitions that had been deleted as unused, restored byte-for-byte from the pre-decomposition
tree (+40 private helpers and 16 imports pulled in only because a restored definition needs them)
- 3 deleted modules recreated as re-export stubs (gateway/startup_watchdog, hermes_cli/observability/
relay_runtime, tools/environments/modal_utils)
- private names (`_x`) get no pointer: they were never API (3,792 skipped)
Verified: all 335 touched modules import under a fresh HERMES_HOME and every manifest name resolves;
the lint reports zero in-tree uses; ruff clean; targeted suites unchanged.
For each issue anchor present in BASE 63279301bc non-test .py and absent on HEAD, the BASE comment/docstring block was re-attached at the HEAD location of the code it explained (matched by the distinctive code line / enclosing def). Sentences already covered by an existing HEAD comment were deduped; the issue number always survives. Insert-only: no code lines changed.
Apply windows_hide_flags() (CREATE_NO_WINDOW; 0 on POSIX) at the
Windows-reachable cua-driver subprocess boundaries: manifest probe,
update checker, CLI fallback transport, doctor health-report spawn,
and the permissions/status runner. Prevents OpenConsole/Windows
Terminal windows flashing into the foreground when spawned from
GUI-backed Gateway/Desktop processes.
The env-probe half of the original PR was already implemented on main
and is not re-applied here.
Salvaged from #62821 by @ZundamonnoVRChatkaisetu (original commits
carried a placeholder 'Claude Code Enterprise' identity; re-authored
to the contributor's GitHub identity).
On Windows with Chinese locale (GBK), subprocess.run(text=True) without
explicit encoding causes UnicodeDecodeError crashes. This fix adds
encoding='utf-8', errors='replace' to all subprocess.run() and
subprocess.Popen() calls that use text=True across 76 non-test Python files.
Fixes#53428 (master tracker for Windows GBK locale crash).
Note: credential_pool.py and electron changes excluded per reviewer request —
those will be submitted as separate focused PRs.
PR #58889 fixed the CLI-fallback transport; review of that fix found the
same leak class at four sibling spawn sites of the third-party cua-driver
binary:
- _resolve_mcp_invocation (cua-driver manifest): no env= at all — full
parent environment inherited
- cua_driver_update_check (check-update --json): telemetry env but no
secret sanitization
- doctor._drive_health_report (<binary> mcp Popen): telemetry env only
- permissions._run (every macOS/Linux permission probe): telemetry env only
All now route through _sanitize_subprocess_env(cua_driver_child_env()),
matching the sanctioned MCP spawn and the #53503/#55709/#58889 strip-by-
default policy for non-terminal spawns. Sanitization degrades gracefully
(falls back to the telemetry env) so doctor/permission probes never break
on an import error.
4 regression tests covering each site.
* fix(windows): stop subprocess console-window popups + add CI guard
The single biggest source of Windows 'terminal popup' bug reports was bare
subprocess.run/Popen calls spawning a console window. The compat helpers
(windows_hide_flags / windows_detach_popen_kwargs) already existed but the
footgun checker had no rule to stop new bare calls from reintroducing the flash.
- scripts/check-windows-footguns.py: new AST-based rule flagging subprocess
calls that can create a new console — output-redirection-aware (capture/
redirect/check_output exempt) and POSIX-only-program-aware (launchctl/
systemctl/brew/etc. exempt). Comprehensive on real popups, no annotation
burden on calls that can't flash.
- Swept all genuine window-spawning sites through windows_hide_flags()/
windows_detach_popen_kwargs(); marked intentionally-visible launches
(editor/terminal/foreground re-exec) with '# windows-footgun: ok'.
- tests/scripts/test_windows_footgun_subprocess_rule.py: behavior-contract
tests + full-repo cleanliness invariant.
- CONTRIBUTING.md: documents the rule + the helper pattern.
* test: accept creationflags kwarg in psutil_android fake_subprocess_run
The Windows no-window sweep added creationflags=windows_hide_flags() to
install_psutil_android.py's subprocess.run call; the test's fake stub had a
fixed (cmd) signature and raised TypeError on the new kwarg.
The subprocess-stdin guard (TUI gateway fd-inheritance protection) flagged
the `permissions grant` call. None of the cua-driver probes/grant read
stdin, so DEVNULL is correct; apply it to the shared `_run` helper and the
grant call.
The card was macOS-only. cua-driver also runs on Windows and Linux, so
fold `cua-driver doctor` (cross-platform binary/health probes) into a
single OS-aware `ready` signal:
- macOS: ready == both TCC grants; keeps the permission rows + grant flow.
- Windows/Linux: no TCC toggles, so ready == driver health, with a
per-OS note (SmartScreen/UIAccess on Windows; X11/XWayland on Linux).
`computer_use_status()` replaces the macOS-only `permissions_status()` and
surfaces `platform`, `ready`, `can_grant`, and the doctor `checks` (non-ok
ones render as warnings). CLI `permissions status`, the REST endpoint, and
the desktop card all key off the one payload. Grant stays macOS-only (400
elsewhere — nothing to grant).
Computer Use already worked through the desktop backend (the cua-driver
toolset enables + installs via Settings -> Skills & Tools), but there was
no in-app way to see or grant the two macOS permissions it needs, so "give
a model my Mac" was tribal knowledge.
The grants attach to cua-driver's OWN TCC identity (com.trycua.driver /
the installed CuaDriver.app), not Hermes -- so no app entitlement is
involved. cua-driver 0.5+ exposes `permissions status/grant`, which we wrap:
- tools/computer_use/permissions.py: thin client over the two subcommands
- hermes computer-use permissions {status,grant}: CLI parity
- GET /api/tools/computer-use/status, POST .../permissions/grant: desktop REST
- ComputerUsePanel: live Accessibility + Screen Recording state with a
Grant button (dialog attributed to CuaDriver), shown in the expanded
Computer Use toolset row. Binary install stays in the existing provider
post-setup runner.
Follow-ups: i18n the card copy; a "Stop driver" control (cua-driver stop)
for the runaway-`serve` case.
