This is an **implementation** package: it registers a provider into `ctx.web`, it does not own the key and it does not register a model-facing tool. It is a function/namespace plugin (`inject: ['web']`).
## Model Experience
| Context surface | What the model sees | Token effect |
|---|---|---|
| Web fetch result, indirectly | Through `dsh-tool-web`, the conversation model sees the final URL, HTTP status, and decoded text or markdown-shaped HTML, or a structured retrieval error. Redirects, headers, and transport mechanics are not added to context unless reflected in an error. | Zero direct tokens. `maxBodyChars` bounds decoded result length before the tool records it; the retained result is resent until compaction. |
## Responsibility split
The provider owns **safe resource retrieval**: URL validation, HTTP transport, redirect policy, a resource-backstop timeout, abort propagation, byte caps, charset decoding, content-type classification, and binary rejection. `@deepseek-ai/dsh-tool-web` owns **presentation** (HTML→markdown, truncation formatting). A non-2xx HTTP response is a *result* (status code + decoded body), not an error; `WebError` is reserved for failures to safely retrieve or represent the resource.

The numeric limits are validated at plugin construction: every cap except `maxRedirects` must be a positive finite number, and `maxRedirects` must be a non-negative integer. An invalid value throws rather than silently constructing a provider with nonsensical limits.

## Known Limitations and Deferred Work
- **SSRF / private-network protection is deferred** — no blocking of private, loopback, link-local, multicast, or otherwise non-public destinations, no DNS-resolve-then-validate, no per-hop re-validation (see [the web capability seam RFC](../../../docs/rfc/implemented/architecture/2026-06-24-web-capability-seam.md)). Until it lands, this provider is an SSRF primitive and **must not be enabled** in a deployment that can reach sensitive internal network targets.
