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).
A non-numeric value in env vars like HERMES_STREAM_RETRIES,
HERMES_KANBAN_SPECIFY_MAX_TOKENS, GOOGLE_CHAT_MAX_BYTES, IRC_PORT, etc.
raised ValueError at import/init and crashed startup. Parse them safely,
falling back to the default.
Unified onto the existing utils.env_int(key, default) helper for core/
hermes_cli/tools modules instead of the original PR's three duplicate
local helpers; plugins keep minimal inline guards (no core-utils import).
All existing max()/min()/`or extra.get()` wrappers preserved.

PR #25580 was authored before #2746 landed on main, so its plugin
versions of browser_use/browserbase/firecrawl ship without the
requests.RequestException → RuntimeError wrapping that 13c72fb4 added
to the legacy tools/browser_providers/ files for #2746. Cherry-picking
the PR + git rm'ing the legacy files (the migration's intent) would
silently revert that network-error fix.
Port the same try/except pattern into the three plugin create_session()
methods. Browser Use managed-mode keeps its raw-exception propagation
(idempotency-key retry semantics).

Addresses findings from two self-review passes pre-merge.
First pass (3-agent parallel review):
1. plugins/browser/browser_use/provider.py: drop the
``_ = managed_nous_tools_enabled`` dead-import-hider in
_get_config_or_none(). The import was actively misleading — the
helper IS used in _get_config() (separate method, separate import),
not here. The "keep static analysis happy" comment was wrong about
what the helper does in this scope.
2. agent/browser_provider.py: drop ``pragma: no cover`` from
is_configured() / provider_name() backward-compat aliases. They ARE
covered by ``TestLegacyAbcAliases`` — the pragma would have masked
future regressions.
3. tools/browser_tool.py: refactor _is_legacy_provider_registry_overridden()
to compare against a module-frozen _DEFAULT_PROVIDER_REGISTRY snapshot
instead of hardcoded set of 3 keys. Future maintainers adding a 4th
built-in provider now just extend _PROVIDER_REGISTRY; the override
detection adapts automatically. Previously the hardcoded
``set(...) != {"browserbase", "browser-use", "firecrawl"}`` would flip
True forever on any 4-key registry, silently routing every install
onto the legacy fixture path.
4. tools/browser_tool.py: when explicit ``browser.cloud_provider`` is set
but the registry has no matching plugin (typo, uninstalled plugin,
discovery failure), emit a WARNING with actionable text instead of
silently falling through to auto-detect. Legacy code surfaced a typed
credentials error via direct class instantiation; this log restores
the signal in the post-migration path.
5. agent/browser_registry.py: trim the triple-redundant _LEGACY_PREFERENCE
documentation. Module docstring + 13-line block-comment + 5-line
inline comment was repeating the same point. Kept the docstring and
trimmed the block-comment to 5 lines.
6. agent/browser_registry.py: upgrade is_available()-raised logging from
DEBUG to WARNING with exc_info=True. A provider's availability check
throwing is unusual enough that users debugging "no cloud provider"
need the traceback in logs.
7. tests/plugins/browser/check_parity_vs_main.py: drop dead top-level
imports (os, shutil, tempfile — only referenced inside the
SUBPROCESS_SCRIPT string literal that runs in a child process).
Second pass (architecture + claim-verification review):
8. tools/browser_tool.py: rewrite the inline comment in _get_cloud_provider
auto-detect branch. Prior text claimed it "routes through the plugin
registry's legacy preference walk so third-party plugins still get a
chance to be selected when they're explicitly configured" — false on
both counts. The branch uses module-level legacy class aliases
(BrowserUseProvider / BrowserbaseProvider) directly; third-party
plugins are intentionally reachable only via explicit
``browser.cloud_provider``. Corrected comment now matches behaviour
and cross-references _LEGACY_PREFERENCE for the firecrawl gate
rationale.
9. tools/browser_tool.py + tests/tools/test_managed_browserbase_and_modal.py:
drop the unused ``get_active_browser_provider as
_registry_get_active_browser_provider`` alias from the
``from agent.browser_registry import ...`` block. It was never
referenced; matching test-stub line in the agent.browser_registry
SimpleNamespace also dropped. ``get_provider`` is still imported (used
by the explicit-config dispatch path at line 535).
10. plugins/browser/firecrawl/provider.py: align emergency_cleanup()
with the early-guard pattern used in browserbase + browser_use
plugins. Previously firecrawl tried the DELETE and relied on
``_headers()`` raising ValueError to trip a "missing credentials"
warning; same final outcome but a different control flow that read
like a bug to a maintainer skimming the three modules. Now: if
is_available() is False, log+return early — identical shape to the
other two providers.
Verification: 54/54 unit tests + 13/13 parity scenarios still pass.
Migrates the remaining two cloud browser providers to plugins:
plugins/browser/browser_use/ — dual auth (direct BROWSER_USE_API_KEY
or managed Nous gateway), idempotency-
key handling for retried managed-mode
creates, x-external-call-id capture.
plugins/browser/firecrawl/ — direct FIRECRAWL_API_KEY only;
distinct from plugins/web/firecrawl/
(same key, different endpoint).
Also drops the 'single-eligible shortcut' rule from
agent.browser_registry._resolve(). Was a copy-paste from
web_search_registry that would have introduced a real behavior change:
a user with only FIRECRAWL_API_KEY set (for web-extract) would silently
get routed to a paid Firecrawl cloud browser on a fresh install — not
matching origin/main, which only auto-detected between Browser Use and
Browserbase. Third-party browser plugins are subject to the same gate:
they require explicit `browser.cloud_provider` to take effect.
Verified end-to-end via plugin discovery:
- 3 plugins register (browser-use, browserbase, firecrawl)
- _resolve(None) with no creds: None (local mode)
- _resolve(None) with only FIRECRAWL_API_KEY: None (matches main)
- _resolve('firecrawl'): firecrawl (explicit wins)
- _resolve(None) with BU+firecrawl: browser-use (legacy walk first hit)
- _resolve(None) with all three: browser-use (legacy walk order)
Migrates tools/browser_providers/browserbase.py → plugins/browser/browserbase/.
Direct credentials only (BROWSERBASE_API_KEY + BROWSERBASE_PROJECT_ID); same
session-creation, 402-handling, and feature-flag logic as the legacy
implementation. Renames is_configured() → is_available() to match the new
BrowserProvider ABC.
The legacy module tools/browser_providers/browserbase.py is NOT yet deleted
and tools/browser_tool.py still references the in-tree class. The dispatcher
cutover happens in a later commit so the plugin migration and the dispatcher
switch land as separate reviewable units.
Verified via plugin-discovery E2E:
- browserbase registers as 'browserbase'
- is_available() correctly tracks BROWSERBASE_API_KEY + BROWSERBASE_PROJECT_ID
- _resolve('browserbase') returns the provider even when unavailable
(so dispatcher surfaces a typed credentials error)
- _resolve(None) returns the provider when it's the single eligible one
