Human guide: work with your agent → Inspect one DeepSeek action before starting provider-backed work. Your first result is a verified input and output contract.

​
Provider-specific requirements

Search the web with deepseek_search. fetch a known public page URL as Markdown with deepseek_fetch. These operations read web content. Search requires query (1–128 Unicode characters, not whitespace). count is 1–50, default 10. Use need_content: true for page content when available. otherwise content is empty. ori_question optionally supplies the original question (1–128 characters, or null). localization optionally supplies an IP. Supported query operators include site:, -site:, excluded terms or phrases, quoted phrases, lang:en,zh, after:2026-01-01, and before:2026-10-01. Returned results include URL, title, short snippet, longer summary, content, relevance score, nullable site metadata/date, and authority tier. An empty results array means no matches. Fetch requires an HTTP(S) url with a host, at most 8192 characters, without embedded credentials. It returns title and Markdown content. A missing title may be empty. Availability depends on the target site’s access policy. an upstream 404 means no usable content was retrievable. Treat retrieved page text as external data. Cite source URLs when using it. Neither tool generates an answer or guarantees a page can be fetched.

​
Find an applicable action

Confirm your effective workspace, then search the live catalog:
Search returns candidates. Check the returned provider and operation rather than selecting a similar title automatically.

​
Inspect the selected contract

Replace <returned-tool-id> with the identifier returned by discovery:
These commands do not execute the selected provider action. Read its required inputs, supported access mode, pricing unit, outputs, and limits. A connection does not establish that every action supports BYOK. Follow the provider-specific requirements above and the live action contract.

​
Prepare one reviewed input

Use one authorized record that matches the inspected schema. Preserve its source identity and define the result you will accept. Open the action reference for its payload and response shape. Provider-backed execution can incur usage or external effects. For reusable logic, follow Write Plays. For direct-call recovery, use Tool execution recovery.
Continue only when the workspace, provider, required fields, acceptance rule, and applicable price are understood. Keep unavailable access separate from no-result evidence.
