dsh-tavily

English | 简体中文

Tavily web search for DeepSeek Harness (DSH) as an opt-in extra search tool — with multiple API keys, rotation/failover, live usage gauge, and a settings card in the Plugins configuration tab.

The built-in web_search tool is never replaced: Tavily is an option on top of the native search, not a swap-in for it. This plugin registers no web-search provider and never rewrites web.searchProvider.

Highlights

• 🧩 Plugin-config settings card — a native card under Settings → Plugins → plugin configuration: add, remove and reveal keys, pick the key-usage strategy, and opt into the advanced tavily_search tool.
• 🔑 Multiple Tavily API keys — manage a flat key list from the DSH settings UI.
• 🔁 Key rotation & failover — round-robin across keys; automatically retries on HTTP 401/429.
• 📊 Live usage gauge — per-key Tavily usage and totals, fetched server-side without exposing keys.
• 🚫 web_search untouched — no ctx.web provider is registered; the card switch only enables/disables the extra tavily_search tool.

Install

One command installs the workspace bundle, which composes the combined dsh-tavily row:

dsh plugin --profile web add github:moguiyu/dsh-tavily

After refreshing the browser, the Tavily Search card appears under Settings → Plugins → plugin configuration. It only appears when the Host half is actually composed — the configuration tab dispatches the card keyed by the namespace the Host serves.

Requirements — DSH is a development preview (0.1.0-rc.x); the keyed plugin-config card needs 0.1.0-rc.7 or newer. The npm name is the scoped @moguiyu/dsh-tavily, not the similarly-named community dsh-tavily provider-swap plugin.

Packages

Credentials

• TAVILY_API_KEYS — comma-separated key list; tavily_search rotates through it, retrying on HTTP 401/429.
• TAVILY_API_KEY — primary key auto-synced to the first key.

Both are managed automatically by the settings card. Keys never leave the server unmasked, and no state file holds key material.

Key usage strategy

• Rotate each key — round-robin; on 401/429 the next key is tried.
• Lowest usage first / Highest usage first — re-order keys by live Tavily usage on save.

Advanced tavily_search tool

The advanced model-facing tool is opt-in and off by default. It exists for direct Tavily-only parameters (search_depth, topic, days, domain filters, include_answer, include_raw_content) and is independent of web_search:

• enabling it never changes the default web_search (the built-in DeepSeek provider stays, along with its native schema);
• disabling it only unregisters the extra tavily_search tool.

The switch lives in the tavily-search settings namespace (settings.yaml) and is mirrored to ~/.dsh/tavily-tool.json so every restart reads the same value.

State files

• ~/.dsh/tavily-manager.json — saved key dates + strategy
• ~/.dsh/tavily-tool.json — advanced tool { "enabled": boolean } (mirror of the settings namespace)
• ~/.dsh/tavily-toggle.json — legacy pre-0.2 tool state; read for migration only
