Implement OutputControl feature allowing LLM clients to request truncated responses to avoid exceeding context windows. Addresses large response handling for crawl4ai MCP tools. New features: - content_offset/content_limit: Paginate text fields (html, markdown, etc.) - max_links/max_media/max_tables: Limit collection sizes - exclude_fields: Omit fields entirely (supports dot-notation) - _output_meta: Response metadata with truncation stats Integrated into all endpoints: /md, /html, /crawl, /crawl/stream, /execute_js, /screenshot, /pdf Fully backward compatible - omitting 'output' param returns full response.
