With zero web credentials configured, web_search/web_extract previously resolved to the nonfunctional firecrawl sentinel and errored. Now the backend resolution walks a strictly-last keyless tier: Parallel's and Exa's public anonymous MCP endpoints (the same free tiers opencode ships as its default search path). - plugins/web/keyless_mcp.py: minimal JSON-RPC tools/call client for mcp.exa.ai + search.parallel.ai (SSE + plain JSON parsing, typed errors, per-process random session id, no user identifiers) - WebSearchProvider.is_keyless_available(): separate weaker tier that never leaks into is_available(), so keyed setups are never pre-empted - Exa/Parallel providers: route to keyless endpoints when their key is absent; keyed SDK path unchanged - registry + _get_backend(): keyless walk (parallel -> exa) strictly after every keyed/importable candidate; check_web_api_key() lights the tools up on zero-credential installs - web.keyless_fallback config key (default true) to disable the tier - docs: web-search.md + configuration.md E2E-verified against both live endpoints from an isolated HERMES_HOME (search + extract via the real dispatchers, disable-flag negative path).
Website
This website is built using Docusaurus, a modern static website generator.
Installation
yarn
Local Development
yarn start
This command starts a local development server and opens up a browser window. Most changes are reflected live without having to restart the server.
Build
yarn build
This command generates static content into the build directory and can be served using any static contents hosting service.
Deployment
Using SSH:
USE_SSH=true yarn deploy
Not using SSH:
GIT_USER=<Your GitHub username> yarn deploy
If you are using GitHub pages for hosting, this command is a convenient way to build the website and push to the gh-pages branch.
Diagram Linting
CI runs ascii-guard to lint docs for ASCII box diagrams. Use Mermaid (````mermaid`) or plain lists/tables instead of ASCII boxes to avoid CI failures.
