`gj-ndZddlmZddlZddlZddlmZmZmZm Z ddZ GddejZ y) u Web Search Provider ABC ======================= Defines the pluggable-backend interface for web search and content extraction. Providers register instances via ``PluginContext.register_web_search_provider()``; the active one (selected via ``web.search_backend`` / ``web.extract_backend`` / ``web.backend`` in ``config.yaml``) services every ``web_search`` / ``web_extract`` tool call. Providers live in ``/plugins/web//`` (built-in, auto-loaded as ``kind: backend``) or ``~/.hermes/plugins/web//`` (user, opt-in via ``plugins.enabled``). This ABC is the SINGLE plugin-facing surface for web providers — every provider in the tree (brave-free, ddgs, searxng, exa, parallel, tavily, firecrawl) implements it. The legacy in-tree ``tools.web_providers.base`` ABCs were deleted in PR #25182 along with the per-vendor inline helpers in ``tools/web_tools.py``; the response-shape contract documented below is preserved bit-for-bit so the tool wrapper does not have to translate. Response shape (preserved from the legacy contract): Search results:: { "success": True, "data": { "web": [ {"title": str, "url": str, "description": str, "position": int}, ... ] } } Extract results:: { "success": True, "data": [ {"url": str, "title": str, "content": str, "raw_content": str, "metadata": dict}, ... ] } On failure (either capability):: {"success": False, "error": str} ) annotationsN)AnyDictListOptionalcd} ddlm}||}|tj|d}|xsdj S#t$rd}Y9wxYw)u:Config-aware env lookup for web providers. Resolves *name* via :func:`hermes_cli.config.get_env_value` (checks ``os.environ`` first, then ``~/.hermes/.env``) so credentials set through Hermes' config layer are visible even when they were never exported into the process environment — gateway sessions, delegate children, and subprocess agent runs (issue #40190). Falls back to a bare ``os.getenv`` when the config module is unavailable (stripped installs, early import contexts). Returns the stripped value, or ``""`` when unset.

Sync implementations that perform blocking I/O (HTTP, SDK calls) should ideally wrap in :func:`asyncio.to_thread` at the call site; small providers can keep their sync shape and let the dispatcher handle threading.
