Three GUI Capabilities-tab defects reported on Windows:
1. Browser rows stuck on 'Setup required' after a successful setup run.
Root causes, all in the readiness probe (not the installer):
- _has_agent_browser() never searched the Hermes-managed Node dir
(%LOCALAPPDATA%/hermes/node / $HERMES_HOME/node/bin) where the
Windows install lands, and probed node_modules/.bin/agent-browser
as the extensionless POSIX shim, which fails exec on Windows
(WinError 193) — now resolved via PATHEXT-aware shutil.which
against both rungs, mirroring _find_agent_browser().
- Cloud rows (Nous Subscription Browser Use, Browserbase, Browser
Use, Firecrawl) declared post_setup: agent_browser, whose
readiness gate requires a LOCAL Chromium build the cloud never
uses — switched to the cloud-scoped 'browserbase' hook (CLI-only).
- _agent_browser_installed() could read browser_tool's stale cached
'Chromium missing' result from before the install ran in the
spawned post-setup process — cache now dropped before probing so
the pill flips to Ready right after a successful run.
2. No way to tell which backend is active, and clicking a row to read
its details silently rewrote config. Row click now only
expands/collapses; activation is an explicit 'Use this backend'
button, the active row carries an 'Active' pill, and the expanded
active row says 'This is your active backend'.
3. OpenAI TTS showed one model and one voice. The options were always
defined but rendered through a native <datalist>, which filters by
the field's current value — a field already set to a valid option
suggested only itself. Replaced with a real combobox (Input +
dropdown) that lists every option, and voice suggestions now track
the selected model per the OpenAI TTS docs: tts-1/tts-1-hd = 9
voices, gpt-4o-mini-tts = 13 (adds ballad, verse, marin, cedar).
Mirrors tests/plugins/web/test_web_search_provider_plugins.py from PR #25182.
31 tests across 5 classes:
TestBundledPluginsRegister (8 tests)
- Three plugins register (browserbase, browser-use, firecrawl)
- Each plugin's name + display_name accessible
- get_setup_schema() returns picker-shaped dict with post_setup hook
- All three lifecycle methods (create_session, close_session,
emergency_cleanup) overridden on every plugin
TestIsAvailable (4 tests)
- browserbase needs BOTH BROWSERBASE_API_KEY and BROWSERBASE_PROJECT_ID
- browserbase: api_key alone or project_id alone insufficient
- browser-use satisfied by BROWSER_USE_API_KEY
- firecrawl satisfied by FIRECRAWL_API_KEY
TestRegistryResolution (8 tests) — most valuable, locks down
pre-migration semantics:
- _resolve(None) with no creds returns None (local mode)
- _resolve('local') short-circuits to None
- _resolve('browserbase') returns provider even when unavailable
(so dispatcher surfaces typed credentials error)
- _resolve('firecrawl') same: explicit-config wins
- _resolve('unknown') falls through to auto-detect
- Legacy walk picks browser-use over browserbase
- browserbase-only configuration: browserbase wins
- **Regression**: firecrawl is NEVER auto-selected even when
single-eligible (preserves pre-migration gate; FIRECRAWL_API_KEY
shared with web firecrawl must not silently route to paid cloud
browser)
TestLegacyAbcAliases (6 tests)
- is_configured() delegates to is_available() for all three plugins
- provider_name() returns display_name for all three plugins
TestPickerIntegration (3 tests)
- _plugin_browser_providers() exposes all three plugins as rows
- Each row carries post_setup='agent_browser'
- browser_plugin_name marker matches browser_provider
All tests use real imports — no mocking of provider classes — so the
suite catches drift in the ABC, registry, picker injection, and plugin
glue layer simultaneously.
31/31 passing.
