master's web_search/web_fetch tools were authored against the old ToolCallPresentation bag; the render-intent union replaces it with a card-tagged discriminated union. Both are simple generic cards, so they declare card:'generic' explicitly.
@deepseek-ai/dsh-tool-web
The model-facing web tool suite — web_search and web_fetch — over the web capability seam (ctx.web). It owns model-facing concerns only: tool names, JSON schemas, snake_case argument names, prompt sections, the result-count bound, result formatting, HTML→markdown presentation, and presentCall. All web access goes through ctx.web; this package never imports a concrete provider.
Each tool is registered independently; a product that wants only one disables the other via config ({ search: false } / { fetch: false }).
Tools
| Tool | Args | Behavior |
|---|---|---|
web_search |
query (string) |
Discovery. Returns an optional answer plus source URLs. max_results is not model-facing — the tool sets the bound (WEB_SEARCH_MAX_RESULTS = 8) and passes it to the seam. |
web_fetch |
url (string), timeout_ms (number, optional) |
Retrieves a specific URL. HTML bodies are rendered to markdown-ish text; text bodies pass through. A non-2xx status is reported, not an error. |
Config
| Key | Default | Meaning |
|---|---|---|
search |
true |
Register web_search. |
fetch |
true |
Register web_fetch. |

Stable registration
Tool registration follows product enablement, not backend availability. A tool stays visible even when its selected provider is missing, misconfigured, ambiguous, or temporarily unavailable; the seam resolves the provider at execution time and execution fails with a structured WebError (e.g. WEB_PROVIDER_UNAVAILABLE, WEB_PROVIDER_AMBIGUOUS), which ToolRegistry.execute() turns into an error tool result the model can read and hooks/UI can route on. This keeps the model schema stable without making plugin load order, credential state, or HMR timing part of the model-facing contract. To remove a web tool entirely, disable it here in config.
The tool reads only the aggregated ctx.web.searchStatus() / fetchStatus() for diagnostics — never each provider's status() directly — so provider selection has one owner.
