Automate litigation portfolio management by creating and tracking matters, deadlines, holds, demands, and communications while drafting legal documents such as briefs, claim charts, chronologies, deposit outlines, and privilege logs. Integrates with legal research, e-discovery, and communication platforms to streamline workflow.
Draft a brief section in house style, consistent with the case theory — every fact cited, every case checked, every argument tied to the theory. Use when the user says "draft the [section]", "write the statement of facts", "argument section on [issue]", or needs a first draft of a brief section.
Build or update a chronology from declared document sources and uploads — dated events extracted, de-duped, and tagged by significance per the matter theory. Use when the user asks to build a chronology or timeline from a production or matter file, says "chron from the production" or "what happened when", or needs a working, statement-of-facts, or witness-specific timeline.
Build or review an element chart — a patent claim chart (infringement, invalidity, or review) or a civil element chart for any cause of action or defense — with every cell pin-cited and gap detection as the priority output. Use when the user asks for a claim chart, element chart, proof chart, infringement or invalidity contention, element-by-element mapping, or asks "what are we missing to prove [claim]".
House cold-start for the litigation plugin — branches by role (in-house, firm associate, solo) and side (plaintiff, defense, both), captures risk calibration, landscape, and house style, and writes the practice profile CLAUDE.md. Use on a fresh install, when the user wants to set up or redo the practice profile, or to re-check available integrations.
Guided customization of your litigation practice profile — change one thing without re-running the whole cold-start interview. Adjust practice role, side (plaintiff / defense / mixed), risk calibration, landscape, house style, escalation contacts, severity vocabulary, or matter workspace paths. Use when the user says "change my [thing]", "update my profile", "edit my config", or "customize".

[!IMPORTANT] Every output from these plugins is a draft for attorney review — not legal advice, not a legal conclusion, not a substitute for a lawyer. They are built with guardrails that reflect that: source attribution on every citation, conservative defaults on privilege and subjective legal calls, jurisdiction assumptions surfaced, and explicit gates before anything is filed, sent, or relied on. A lawyer reviews, verifies, and takes professional responsibility for anything that leaves the building. These plugins make that review faster; they do not replace it.
These plugins do not represent Anthropic's legal positions. They are tools that help lawyers analyze issues. Where a skill includes a checklist item, a suggested framework, a risk flag, or a characterization of case law or regulatory guidance, that is an aid to the reviewing attorney's own analysis, not a statement of Anthropic's view of the law. The law in many of these areas is unsettled and evolving. The attorney using the plugin — not the plugin, and not Anthropic — is responsible for the legal positions taken in their work product.
What's in the repo:
CLAUDE.md practice profile that every skill reads from.Each agent is named for the workflow it runs. They're the most common surface — start with the ones that match your work, then tune the underlying skill, the practice profile, and the connectors to how your team does it.
Document processing suite — Excel (xlsx), Word (docx), PowerPoint (pptx), and PDF generation and manipulation.
Anthropic's production Excel skill - read, analyze, create and edit .xlsx workbooks with formulas, formatting and charts. The most finance-relevant skill there.
Anthropic's production Word skill — create and edit .docx with tracked changes. For memos, technical accounting papers and reports.
Anthropic's production PDF skill — extract text and tables, fill forms and generate PDFs. Essential for financial statements, contracts and scanned invoices.
Anthropic's production PowerPoint skill — create and edit .pptx decks. The render layer for board and management packs.
