Add Jina Reader (https://jina.ai/reader/) as a native fallback provider
for web_fetch, similar to how Firecrawl is integrated.
Jina provides high-quality content extraction with:
- PDF support (native text extraction)
- Image captioning (via vision language models)
- JavaScript rendering (browser engine option)
- Token-based pricing (10M free tokens, more affordable than Firecrawl)
- Markdown-optimised output for LLM consumption
Changes:
- Add ToolsWebFetchJinaSchema to zod-schema.agent-runtime.ts
- Add fetchJinaContent() and tryJinaFallback() to web-fetch.ts
- Update fallback chain: Readability -> Jina -> Firecrawl -> error
- Add UI hints for Jina config options in schema.ts
- Add docs/tools/jina.md documentation
- Update docs/tools/web.md to reference Jina
Configuration example:
tools.web.fetch.jina.apiKey or JINA_API_KEY env var
