SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Legal professionals need synthesized answers to U.S. legal questions grounded in caselaw, statutes, and regulations, but manually searching Westlaw and compiling authority is slow. This Skill automates the full research cycle through the CoCounsel Legal MCP server and returns a written, citation-backed research report. ## Core Features & Use Cases - Autonomous Research Cycle: Starts a Deep Research session, polls for completion with adaptive backoff, and retrieves the final report without manual intervention. - Multi-Jurisdiction Support: Accepts up to three jurisdictions per query and prompts the user when none are specified. - Scope Guardrails: Recognizes out-of-scope requests (document retrieval, analytics, drafting, non-U.S. law) and redirects users to the appropriate Westlaw tool. - Use Case: A litigator asks how courts in California and New York have ruled on enforceability of non-compete clauses; the Skill frames the question, runs Westlaw Deep Research, and delivers a verbatim report with inline citations. ## Quick Start Ask a U.S. legal research question such as "Research how courts have applied the doctrine of promissory estoppel in California and New York" and the Skill will run the full research cycle and return the report.

FAQPage Schema
How do I run Westlaw Deep Research from Claude?

Ask a U.S. legal research question in natural language and specify up to three jurisdictions. The Skill calls the CoCounsel Legal MCP server to start research, polls until complete, and returns the full report with citations.

What legal questions can Westlaw Deep Research answer?

It handles questions answerable from caselaw, statutes, regulations, administrative materials, secondary sources, and Practical Law content. Examples include how courts ruled on an issue, elements of a claim, or arguments on both sides of an unsettled question.

When should I not use Deep Research for a legal task?

Avoid it for retrieving full document text, analytics, calculations, outcome predictions, drafting, non-U.S. law, boolean searches, or comparisons across more than three jurisdictions. The Skill redirects those requests to the appropriate Westlaw tool.

Does Deep Research require a subscription or special setup?

Yes, it requires a CoCounsel Legal subscription with the MCP connector enabled for the user's account, and the cocounsel-legal MCP server must be connected. Access questions go to [email protected].

Can I ask follow-up questions on a completed research report?

Yes, follow-up questions on the same topic reuse the existing conversation through the follow_up_deep_research tool rather than starting a new research session, preserving context from the original query.
