- spill-policy reserves the spill notice's byte cost inside maxInlineBytes, so the replacement (preview + notice) never exceeds the documented model-facing cap. When the notice alone fills the budget the preview is empty; when even a notice-only replacement is not smaller than the original, the inline result is kept (spilling would only add bytes). - retention TextRetainer trims an oversized single suffix chunk to the last suffixCap bytes on push, so tail/headTail retention stays bounded by suffixCap instead of retaining and re-copying the whole chunk in finish() — this is the spill preview path, which pushes the whole result as one chunk.
@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 (the searchMaxResults config, default 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. |
searchMaxResults |
8 |
Upper bound on sources returned by one web_search call (the seam truncates a longer provider list and flags it). |

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 never calls a provider's status() and never enumerates providers — its only execution path is ctx.web.search() / ctx.web.fetch(), and provider unavailability reaches it as the structured WebError codes selection throws at execution time. Provider selection stays entirely inside the seam, with one owner.
