The Web search switch selects the DeepSeek Search and Fetch APIs together,
and both reuse the DeepSeek chat key by default. Neither provider answered
readiness, so a step without a usable key was offered web_search and
web_fetch whose every call failed, and a conversation on another provider's
model or behind a gateway sent the chat key to DeepSeek.
dsh-web gives WebFetchProvider an optional ready(llmProvider) and adds
ctx.web.fetchReady(), which asks only the provider fetch() selects, as
searchReady() does for search. tool-web registers web_fetch with a step
activation condition on fetchReady(), so a step that cannot fetch leaves the
tool out of declarations, guidance, and PTC bindings and refuses a call to
it as UNKNOWN_TOOL; without web_fetch the search guidance uses its
search-only text. The shipped HTTP fetch provider has no ready() and stays
admitted.
web-deepseek-api applies the API-key rules of Messages search to both APIs:
without a literal apiKey, an apiKeyEnv other than DEEPSEEK_API_KEY, or a
baseURL other than the default, the chat key goes only to the DeepSeek
routes and only to an API base on the official chat route's origin. The
refusal sits in the key's only resolver, and both providers' ready()
answers presence in the order an operation resolves credentials. The
transport repeats these checks so the package still does not depend on
dsh-web-search-deepseek.
