You have access to 9 research tools via the CLI at scripts/cli.py. Run all commands with uv run scripts/cli.py.

Every tool returns deterministic, auditable output. There is no in-server LLM — you're the one doing the synthesis.

When to chain tools

• Found a URL from search? → content_operations --operation retrieve --url <url>
• Want to assess source trust before using results? → content_operations --operation score --urls '[…]'
• Two sources seem to disagree? → content_operations --operation find_conflicts --urls '[…]'
• Found a PDF link? → document_analysis --url <url>
• Need to explore a website? → map_website --url <url> --mode docs
• Need a unified entity profile in one shot? → research_topic --mode entity --topic "OpenAI"
