DeepSeek Harness / dsh users (and Claude Code, Codex, Pi, OpenCode) who need reliable, free web search without API keys

03DSH integration and capability boundaries
Native dsh plugin (web profile) + agent skill: adds web/X search and page fetch with a free keyless Firecrawl default and automatic failover.
Keyless web search + page fetch (Firecrawl default)
query or URL→titles/snippets/URLs or cleaned page content
Automatic failover across engines
configured engines→next engine takes over on failure/quota
X (Twitter) search via Grok Build
query→X corpus results
04Who is it for? When not to use it?
Good for
- DeepSeek Harness / dsh users (and Claude Code, Codex, Pi, OpenCode) who need reliable, free web search without API keys
05Compatibility, maintenance and safety notes
- The default Firecrawl keyless tier gives 1,000 free credits/month; other engines (Tavily, Exa, Firecrawl key, Grok Build, Antigravity CLI) need sign-in or API keys, each with their own quotas and terms the user must comply with.
- API keys live in ~/.modsearch/config.json (mode 0600, masked when shown) or environment variables (TAVILY_API_KEY, EXA_API_KEY, FIRECRAWL_API_KEY); official endpoints are never written as default config.

06Frequently asked questions
Do I need an API key?
No for the default Firecrawl keyless tier (1,000 free credits/month, no account). Add a free Tavily/Exa/Firecrawl key or sign in to Antigravity CLI/Grok Build for more channels.
Which engines are supported?
Firecrawl (default, keyless), Antigravity CLI, Tavily, Exa, Grok Build (X/Twitter), and local page fetch, with automatic failover.
How do I install into dsh without the CLI?
Settings → Plugins → Plugin config → ModSearch card: pick the engine, fill a key or self-hosted endpoint, tick failover engines, save.
What happens if one search channel fails?
Automatic failover — the next configured engine takes over; per-engine key rotation handles auth/quota failures.
