@anysearch/dsh
Official AnySearch web search plugin for DeepSeek Harness.
English | 简体中文
@anysearch/dsh connects AnySearch to DeepSeek Harness. It powers Harness's native web_search and adds capability discovery, vertical search, and bounded batch search.
Quick start
Requires Node.js 22.19 or Node.js 24+, pnpm 11.7, and DeepSeek Harness. The DSH plugin command uses pnpm to manage profile dependencies, so pnpm must be available on PATH.
Install the plugin into the web profile:
npx -y @deepseek-ai/dsh plugin --profile web add @anysearch/dsh
Start DeepSeek Harness:
npx -y @deepseek-ai/dsh web
No API key is required for a quick start. Requests use AnySearch's anonymous quota until you configure one.
What you get
- Native AnySearch results through Harness's built-in
web_search.
- Live capability and vertical-search discovery.
- Advanced search with tags, parameters, region, and language.
- Concurrent batches of one to five searches with partial-failure handling.
- Optional cleaned page content with a bounded rendering budget.
- Caller cancellation, response validation, and redirect-safe credential handling.
Optional API key
The plugin works without an API key using AnySearch's anonymous quota. For account-level quota, add the credential to $DSH_HOME/.credentials.yaml (~/.dsh/.credentials.yaml by default):
ANYSEARCH_API_KEY: "as_sk_your_key"
The plugin resolves the managed credential for every operation, so credential rotation reaches the next request without restarting DSH. A launching ANYSEARCH_API_KEY environment variable has higher priority.
Inspect the composed profile without exposing the credential value:
npx -y @deepseek-ai/dsh --profile web --dump-config
Tools
| Use case | Harness tool |
|---|
| Ordinary web search | web_search |
| Discover available domains and tags | anysearch_capabilities |
| Vertical or parameterized search | anysearch_search |
| Run one to five searches together | anysearch_batch_search |
For ordinary prompts, let Harness select the tool. Models can discover live domain and parameter definitions before making a specialized search.
Configuration
The bundled profile layer selects AnySearch as the existing ctx.web provider and mounts the advanced tools. A profile can replace the provider row with its own complete configuration:
- id: web-search-anysearch
config:
apiKeyEnv: ANYSEARCH_API_KEY
baseURL: https://api.anysearch.com
maxRenderedContentChars: 12000
| Field | Default | Purpose |
|---|
apiKeyEnv | ANYSEARCH_API_KEY | DSH credential reference; missing uses anonymous access |
baseURL | https://api.anysearch.com | AnySearch API base URL |
maxRenderedContentChars | 12000 | Maximum cleaned-content characters rendered to the model per advanced tool call |
Manage the plugin
Update:
npx -y @deepseek-ai/dsh plugin --profile web update @anysearch/dsh
Remove:
npx -y @deepseek-ai/dsh plugin --profile web remove @anysearch/dsh
Compatibility and limitations
- DeepSeek Harness is in developer preview and may make compatibility-breaking changes.
- This plugin currently does not provide
anysearch_extract.
- Configure the API key through DSH-managed credentials or an environment variable; the DSH settings page does not currently provide a third-party Provider credential field.
