Removes the legacy in-tree provider scaffolding that PR #25182 fully
replaced with the plugin architecture:
tools/web_providers/__init__.py (6 lines)
tools/web_providers/base.py (89 lines — old ABCs)
tools/web_providers/ARCHITECTURE.md (73 lines — old design doc)
These were the staging-ground ABCs and provider modules that the
plugin migration absorbed. All seven web providers now implement the
single :class:`agent.web_search_provider.WebSearchProvider` ABC and
live under ``plugins/web/<vendor>/``. Nothing else in the tree imports
``tools.web_providers`` — verified via grep before deletion.
Test migration (tests/tools/test_web_providers.py)
--------------------------------------------------
Rewrote ``TestWebProviderABCs`` to test the new unified ABC at
:mod:`agent.web_search_provider`:
- test_cannot_instantiate_abc_directly — abstract ``name`` + ``is_available``
- test_concrete_search_only_provider_works — exercise default
``supports_extract=False`` / ``supports_crawl=False`` flags
- test_concrete_multi_capability_provider_works — exercise all three
capabilities, async extract supported (declared sync here for
simplicity; real plugins like parallel + firecrawl use async)
- test_search_only_provider_skips_extract_and_crawl — verify
``supports_*()`` flags default to False so search-only providers
don't have to implement extract() or crawl()
The 9 other tests in the file (per-capability backend selection,
DEFAULT_CONFIG merge, dispatcher routing) test public helpers in
``tools.web_tools`` that still exist and pass unchanged.
agent/web_search_provider.py docstring updated to reflect that the
legacy ABCs no longer exist; the response-shape contract is preserved
bit-for-bit so external consumers see no behavioral change.
Net diff
--------
- tools/web_providers/ removed (-168 lines)
- tests/tools/test_web_providers.py rewritten ABC section (+78/-30 net,
same coverage, new API)
- agent/web_search_provider.py docstring (-3/+5 lines)
Verified
--------
- 173/173 targeted web tests pass
- 12/12 ABC contract tests pass with the new interface
- No remaining grep hits for ``tools.web_providers`` outside of
intentional historical references in plugin docstrings.
Two ABC additions to cover the surface area of the remaining four
providers (exa, parallel, tavily, firecrawl) which were untouched by the
initial spike:
1. supports_crawl() + crawl() — Tavily natively crawls a seed URL via
its /crawl endpoint. Exposing supports_crawl=True lets the crawl
tool's dispatcher route to Tavily when configured, falling back to
the auxiliary-model summarization path otherwise. Firecrawl could
add this in a follow-up (the SDK supports it; we just don't surface
it as a tool today).
2. Async-or-sync extract() — Parallel's SDK is natively async
(AsyncParallel.beta.extract); Exa and Tavily are sync; Firecrawl is
sync but called inside asyncio.to_thread() with a 60s timeout. The
ABC docstring now permits either shape: implementations declare
their own sync/async signature and the dispatcher uses
inspect.iscoroutinefunction to detect and await.
Also adds get_active_crawl_provider() to web_search_registry mirroring
the search/extract resolvers, with web.crawl_backend as the explicit
override config key.
No behavior change on its own — these are scaffolds for the four
remaining provider migrations.
