Surfaced by local E2E behavior-parity testing of PR vs origin/main: the
plugin-migrated dispatchers were quietly changing the error envelope
shape returned to function-calling models on unconfigured systems.
Two findings, both from per-result error wrapping bleeding into the
pre-flight configuration error path:
1. **search**: ``firecrawl.search()`` caught the
``ValueError("Web tools are not configured...")`` from
``_get_firecrawl_client()`` and returned it as
``{"success": False, "error": ...}``, losing the legacy
``{"error": "Error searching web: ..."}`` envelope that
``tool_error()`` emits on main. Models that special-case the
``error`` key still detect the failure, but the prefix is part of
the legacy contract some users rely on.
2. **crawl**: ``firecrawl.crawl()`` caught the same pre-flight
``ValueError`` and wrapped it as a per-page error inside
``results[0]``. Main short-circuits on ``check_firecrawl_api_key()``
BEFORE dispatching, so its unconfigured response is
``{"success": False, "error": "web_crawl requires Firecrawl..."}``
at the top level. The PR's per-page burying hid the failure inside
``results[]`` where models that check ``result.get("error")`` would
miss it.
Fix:
- ``plugins/web/firecrawl/provider.py``: pull
``_get_firecrawl_client()`` outside the broad ``try`` in
``search()``. Pre-flight ``ValueError`` / ``ImportError`` propagate
to the dispatcher's top-level exception handler. In-flight SDK
errors still get wrapped as ``{"success": False, ...}``.
- ``tools/web_tools.py``: mirror main's upstream availability gate in
``web_crawl_tool``. When the resolved crawl provider is
``is_available()==False``, short-circuit BEFORE dispatching with the
same top-level error shape main emits.
- ``tests/tools/test_web_providers.py``: 2 regression tests
(``TestUnconfiguredErrorEnvelopeParity``) lock in the behavior so
future plugin work can't undo this.
Verified via local subprocess-based parity test (14/14 scenarios match
origin/main shape exactly) and full 210/210 web test suite green.
