🔧 Capabilities

• "user" — the signal is relevant to the user's personal knowledge graph
• "agent_only" — the signal is agent-initiated research with no demonstrated user connection
• sift.search — execute a search query with automatic tier selection and query rewriting
• sift.research — run a multi-source research session producing a structured research journal
• sift.verify — fact-check a specific claim across multiple sources with consensus scoring
• sift.summarize — summarize a document or URL with structured entity extraction
• sift.extract — extract entities, claims, statistics, and relationships from content
• sift.thread.list — list active research threads with entity overlap detection
• sift.status — return current state: active threads, quota usage, source reputation summary
• sift.journal — write journal for the current run; called at end of every run
• sift.update — pull latest from GitHub source; preserves journals and data
• sift.fetch [url] — extract clean Markdown content from a URL. Runs Scrapling first (fast HTTP for static sites, headless browser mode for JS-heavy sites); falls back to Jina Reader (r.jina.ai/<url>) if Scrapling output is below content threshold. Returns Markdown with structure preserved. Use for summarizing a specific page or document the user provides.
• sift.webwright — execute an interactive web task using browser automation (Playwright Firefox). Write the plan, exploration screenshots, instrumented final_script.py, execution log, and self-verification into {agent_root}/commons/data/ocas-sift/webwright/. For form filling, multi-step flows, JS-heavy sites, interactive filtering, or any task where the browser is the workspace. Read references/webwright-integration.md before first use.
