f-trycua's #50855 test file predated the cross-platform PR (#50552) and
reintroduced two stale tests asserting Linux is unsupported
(test_*_non_macos_*, patching platform.system="Linux" and expecting a
no-op/warn). Linux + Windows are supported now, so install proceeds on
those platforms. Restore main's cross-platform-correct versions:
test_*_on_unsupported_platform_* using FreeBSD as the genuinely
unsupported case.
`hermes computer-use install` refused to install on Linux, Windows, and
macOS x86_64 because the pre-install asset probe was hitting the wrong
GitHub endpoint AND duplicating tag-resolution logic the upstream
installer already does correctly.
`_check_cua_driver_asset_for_arch()` queried
`https://api.github.com/repos/trycua/cua/releases/latest`. On trycua/cua:
- cua-driver-rs releases (the binary the installer fetches) are marked
**prerelease** on every cut. GitHub's `/releases/latest` explicitly
skips prereleases.
- The Python package releases (`cua-agent`, `cua-computer`, `cua-train`)
are non-prerelease and end up as the "latest" instead.
Live API check today:
$ curl -sf https://api.github.com/repos/trycua/cua/releases/latest \
| jq '{tag:.tag_name, asset_count: (.assets|length)}'
{ "tag": "agent-v0.8.3", "asset_count": 0 }
The probe sees zero assets, prints "Latest CUA release has no Linux
x86_64 asset", and skips install on every Linux / Windows / macOS-x86_64
host — even though the cua-driver-rs-v0.6.0 release ships 19 binary
assets covering all those platforms.
Filtering `/releases?per_page=N` for the `cua-driver-rs-v*` prefix
fixes the bug, but it duplicates tag-resolution logic the upstream
`_install-rust.sh` already does correctly via `CUA_DRIVER_RS_BAKED_VERSION`
(auto-baked by CD on every release, with a `/releases?per_page=N` API
fallback for dev checkouts). The right answer is to trust that
contract instead of mirroring it in Python where it can drift.
Two paths get the same outcome without the probe:
1. **Fresh install**: run `install.sh` directly. It has the baked
release tag, fetches the right asset, and errors with a clear
message on missing-arch downloads. No preflight needed.
2. **Upgrade path**: `cua_driver_update_check()` (separately added)
shells `cua-driver check-update --json` against the installed
binary, which returns the canonical update answer from the same
source the installer uses.
- `hermes_cli/tools_config.py`: delete `_check_cua_driver_asset_for_arch`
and its two call sites in `install_cua_driver`. Replace with an
inline comment near the top of the module explaining the rationale.
- `tests/hermes_cli/test_install_cua_driver.py`: drop the
`TestCheckCuaDriverAssetForArch` block. Add `TestArchProbeRemoval`
with three regressions:
- `test_probe_function_is_gone` — asserts the deleted helpers stay
deleted.
- `test_fresh_install_does_not_call_github_api` — asserts the
install path doesn't hit GitHub directly from Python anymore.
- `test_upgrade_with_binary_does_not_call_github_api_directly` —
same for the upgrade path.
All 9 `test_install_cua_driver` tests pass.

The install pre-flight asset probe queried trycua/cua's `releases/latest`,
which floats across the monorepo's components (agent-*, computer-*, lume-*,
train-*) — most ship zero binary assets. So the probe false-negatived and
hard-blocked `install_cua_driver` (line 770: `if not probe: return False`)
BEFORE the upstream installer ran, on Linux, Windows, and Intel macOS — even
though the installer it gates resolves the right tag and would have succeeded.
Net effect: the normal enable path (`hermes tools` → Computer Use post-setup,
and `hermes computer-use install`) refused to install on every platform this
PR claims to support.
Fix: list `/releases?per_page=100`, pick the newest `cua-driver-rs-v*` tag,
and match its assets on OS-token + arch — mirroring what the upstream
`install.sh` already does. Fail open if no driver release surfaces (installer
remains the source of truth). Adds an OS-token gate so a darwin asset can't
satisfy a Linux probe.
Tests: updated the install-probe fixtures to the list-of-releases shape with
`cua-driver-rs-v*` tags + OS-token asset names; added a regression guard
(`test_releases_latest_tag_ignored_picks_driver_rs_tag`) for the monorepo
floating-latest case. 25/25 install + 192 computer_use tests green.
Verified live: probe returns True for all six platform/arch combos against
the real GitHub releases API.
Make the computer_use toolset platform-agnostic by driving cua-driver on
macOS, Windows, and Linux. Consumes the 8 cua-driver decoupling surfaces
(capability discovery, structuredContent AX tree, opaque element_token,
click button enum, explicit mimeType, machine-readable manifest,
structured list_windows, structured health_report), each degrading
gracefully on older drivers.
Adds `hermes computer-use doctor` (drives cua-driver health_report with a
per-OS check matrix and an exit 0/1/2 ok/degraded/blocked contract), full
typed wrappers for the previously-uncovered cua-driver tools plus a generic
call_tool escape hatch, per-session agent-cursor lifecycle, platform-aware
system-prompt guidance (host-deterministic, cache-safe), and honors
HERMES_CUA_DRIVER_CMD end-to-end.
Replaces the macOS-only skills/apple/macos-computer-use skill with a
cross-platform skills/computer-use skill, and refreshes the EN + zh-Hans
docs.
Supersedes #44221 (Windows-enablement salvage of #30660).

The upstream cua-driver installer resolves the latest release and attempts
to download an architecture-specific asset. When the release only ships
arm64 builds (as of v0.1.6), the installer fails with a raw 404 on Intel
macOS with no clear path forward.
Add _check_cua_driver_asset_for_arch() that probes the GitHub Releases API
before running the installer. If the latest release has no x86_64/amd64
asset, print a clear warning and link to the upstream issue. On arm64 or
API failure, fail open and let the installer proceed as before.
Fixes#24530
Six days after #23937 (608 fixes) the codebase had accumulated 241 new
PLR6201 violations. Same mechanical `x in (...)` → `x in {...}` fix,
same zero-risk profile: set lookup is O(1) vs O(n) for tuple and the
two are semantically equivalent for hashable scalar membership tests.
All 241 instances fixed via `ruff check --select PLR6201 --fix
--unsafe-fixes`, zero remaining. Every changed value is a hashable
scalar (str/int/None/enum/signal); no risk of unhashable runtime
errors. No behavior change.
Test plan:
- 119 files changed, +244/-244 (net zero) — exactly one-line edits
- `ruff check` clean afterward
- Compile checks pass on the largest touched files (cli.py, run_agent.py,
gateway/run.py, gateway/platforms/discord.py, model_tools.py)
- Subset broad test run on tests/gateway/ tests/hermes_cli/ tests/agent/
tests/tools/: 18187 passed, 59 pre-existing failures (verified against
origin/main with the same shape — identical failure count, identical
category — all xdist test-order flakes unrelated to this change)
Follows the same template as PR #23937 ([tracker: #23972](https://github.com/NousResearch/hermes-agent/issues/23972)).
cua-driver was only installed once on toolset enable: `_run_post_setup` early-returns when the binary is already on PATH, so upstream fixes (e.g. v0.1.6 Safari window-focus fix) never reached existing users without manual reinstall.
Two refresh points now:
- `hermes update` re-runs the upstream installer at the end of the update if cua-driver is on PATH (macOS-only, no-op otherwise). Ties driver freshness to the user-controlled update cadence — no startup latency, no per-launch GitHub API call.
- `hermes computer-use install --upgrade` for manual force-refresh.
The upstream `install.sh` always pulls the latest release, so re-running is the canonical upgrade path. No version-comparison logic needed.
`hermes computer-use status` now shows the installed version, and points at `--upgrade` for refreshing.
