* fix(web-search-deepseek): disable thinking for auxiliary search requests The provider discards the generated text of the auxiliary Messages turn, so reasoning tokens have no consumer. DeepSeek enables thinking by default, which adds latency and output tokens to every search. Fixes #6099. * feat(web): add opt-in traditional Search and Fetch APIs * test(web): verify API settings persistence and refresh Session evidence * fix(web): require an explicit Search API base with its route prefix * docs(web): document direct Search and Fetch API decisions * fix(web): keep Messages search default behind the new Web Search API switch - Rename useTraditionalApi/traditionalBaseURL to useSearchApi/searchApiBaseURL and label the switch "Use the new Web Search API"; Messages search stays the default. - Default the Search / Fetch API base to https://api.deepseek.com/v1/tools. - Authenticate the Search API with an API key only: DeepSeek Account tokens returned an empty HTTP 404 on /v1/tools/* when probed on 2026-10-16. - Remove the count setting, which tool-web's maxResults always overrides, and the undocumented DeepSeek-API-Version header. - Name the active API's base URL field and the current settings path in endpoint guidance; re-record the endpoint guidance Session. - Keep WebFetchResult.statusCode required: DeepSeek Fetch reports HTTP 200 and drops the page title, so the fetch-metadata widening and its upgrade guide are removed. * fix(web): accept account sign-in on the live Search API The public Search and Fetch routes went live on 2026-10-16 and accept the DeepSeek Account token, so account-route Sessions send it to the Search API as they do for Messages search, and the settings copy no longer says account sign-in does not apply. Record the live behavior in the README and Agent Note: summaries of 1,000-2,300 characters, an HTTP 500 for an unresolvable Fetch target, and migration notes for gateways without /v1/tools routes. Test doubles now use the live response fields and RFC 3339 offsets. * feat(web): configure Search API result count and send the triggering question - Add web-search-deepseek.count (1-50, default 10, the service default) and show it as "Results per search" in Search API mode, where "Max searches per request" applies only to Messages; a smaller request maxResults still wins. - Send the initiating Session's latest human prompt as ori_question, with whitespace collapsed and cut to the API's 128-character limit; blank or absent prompts omit it, and sendOriginalQuestion: false disables it. The settings hint states that the question is sent. - Match the web search double on the request's query field, since ori_question now carries every query in the prompt. * fix(client): unify web search endpoint override controls * feat(web): configure registered search and fetch providers through shared settings * feat(web): include Exa and Perplexity in provider settings * test(web): cover provider settings branches and refresh plugin snapshots * revert(web): drop the provider dropdown, schema-driven form, and Exa/Perplexity settings Revert aed8c5cb609, d88c47dcd80, and 036a5a337d3. The Web search settings page returns to the DeepSeek toggle; the DeepSeek Search and Fetch API split is reintroduced as one plugin in the following commit. * feat(web): move the DeepSeek Search and Fetch APIs into web-deepseek-api The new web-deepseek-api plugin registers deepseek-search-api and deepseek-fetch-api over one credential and API base, and exports the authentication and redirect-rejecting transport that web-search-deepseek now reuses for Messages search only. The web service reads searchProvider and fetchProvider for each operation, so the Web search settings switch selects both APIs together on save and restores Messages search with local HTTP fetch when turned off. The switch hint links to the DeepSeek search and fetch guide. * refactor(client): keep the web search endpoint fields on the shared override controls Drop the always-visible reset and the inherited-address placeholder from the Web search page, restoring ui-primitives to its base. Each endpoint field shows the selected section's effective value and offers Reset to default only for an override, like every other settings field. * refactor(web): keep Messages search independent of web-deepseek-api Restore dsh-web-search-deepseek to its own credential and transport code, keeping only the disabled-thinking request and the current settings guidance, so the Messages plugin no longer depends on the Search and Fetch API package. dsh-web-deepseek-api keeps its transport internal; the regions that repeat the Messages helpers carry jscpd:ignore markers, with the rationale recorded in the Search and Fetch API Agent Note. * refactor(web): keep the web-deepseek-api request type module-private --------- Co-authored-by: LegGasai <[email protected]>
DeepSeek Harness
English | 中文
DeepSeek Harness (dsh) is an open-source agent harness developed by DeepSeek AI.
It is built on an everything-is-a-plugin architecture and powered by Cordis, whose design is described in A Programming Paradigm for Spatiotemporal Composability.
Documentation: https://deepseek-harness.github.io/deepseek-harness/
Developer preview
DeepSeek Harness is in developer preview and iterating rapidly. THERE WILL BE COMPATIBILITY-BREAKING CHANGES.
Review the safety notice before running the project.
Run
Run from npm
Install Node.js, then run:
npx @deepseek-ai/dsh web
The command starts the Web UI at http://127.0.0.1:3080 by default and opens it in the default browser for a local launch. An SSH launch only prints the host URL because the SSH client or editor owns the local forwarded address. Pass --no-open to run the server without opening a browser. See Web UI guide.
Run from source
To run from a repository checkout:
git clone https://github.com/deepseek-ai/deepseek-harness.git
cd deepseek-harness
pnpm install
pnpm run build
pnpm dsh web
pnpm run build prepares the repository artifacts. pnpm dsh web uses those built artifacts without rebuilding.
Community and support
- Submit feedback or bug reports through GitHub Discussions.
- Add the
dsh-plugintopic to your plugin repository for discoverability. - Join DeepSeek Harness Discord community.
Contributing
See CONTRIBUTING.md.
Development
Start with the development guide and architecture documentation.
pnpm run dev:web builds, serves, and rebuilds client bundles on source edits in one terminal, and make help lists the matching Make targets for Web and Desktop; the guide's application commands section owns the full table.
For agents, follow AGENTS.md.
