dsh-subscription-search

In DeepSeek Harness, web search is often fragmented across providers—Ollama, Exa, DeepSeek, ChatGPT, and Grok each operate in isolation with no shared orchestration or failover. dsh-subscription-search introduces a configurable search chain (search-chain/v1) that wires these backends into a single, policy-driven pipeline, turning ad-hoc per-provider calls into coordinated dispatch.

The chain follows a default order of ChatGPT, Grok, Ollama, Exa, and DeepSeek. Exa, DeepSeek, and Ollama are built-in adapters resolved through standard DSH credential refs; ChatGPT and Grok are optional callable adapters that an account plugin registers at runtime, and the package starts and searches fine without them. The chain owns enabled flags, per-backend and total deadlines, automatic fallback, cancellation, empty-result semantics, and structured diagnostics. The Ollama adapter calls the hosted web_search endpoint, draws on the free Ollama account quota when an API key is present, and falls through transparently when the quota is exhausted—all without requiring a restart.

This plugin targets DSH users who rely heavily on multi-source web search: you want a single request to fan out across engines, automatic failover when a backend is unavailable, a unified policy panel for ordering and timeouts, and a search component that stays out of OAuth, credential storage, and quota UI. If you only need single-engine search or already have a full orchestration layer in place, the incremental value here is limited.
