bettercallclaude

Swiss Legal Intelligence Plugin for Cowork and Claude Code

BetterCallClaude transforms legal research, case strategy, and document drafting for Swiss lawyers. It provides deep integration with Swiss legal databases, multi-lingual analysis (DE/FR/IT/EN), and built-in Anwaltsgeheimnis (attorney-client privilege) protection -- 21 agents, 19 commands, 10 skills, and 6 MCP servers covering BGE/ATF/DTF precedent research, litigation strategy, adversarial analysis, legal drafting, and citation verification across all 26 Swiss cantons.

Overview

The Framework at a Glance

BetterCallClaude provides a structured methodology for handling legal work with AI assistance. The framework consists of five interconnected phases.

What's New in v4.1.2

Windows 11 fix: cross-platform privacy hook -- The Anwaltsgeheimnis PreToolUse hook has been rewritten in Node.js (replaces bash script). This fixes /setup freezing and commands not loading on Windows 11 Cowork Desktop where bash is not natively available.

• Cross-platform: hook now runs on Windows, macOS, and Linux without any shell dependency
• Same protection: identical pattern matching (14 Anwaltsgeheimnis patterns, DE/FR/IT + legal refs)
• No setup required: Node.js is always available in Cowork environments

What's New in v4.1.1

Legal Prompt Engineer Agent + /refine command -- New specialist transforms vague queries into structured legal prompts through Socratic dialogue, with workflow recommendations and multi-lingual terminology guidance.

• Two invocation paths: /bettercallclaude:refine [query] or /bettercallclaude:legal --refine [query]
• Socratic refinement: Interactive dialogue fills gaps (jurisdiction, domain, party position)
• Workflow recommendations: Suggests optimal agent pipelines (e.g., researcher → strategist → drafter)
• Mode flags: --quick for fast results, --optimize for experienced users
