BetterCallClaude

Swiss Legal Intelligence Plugin for Cowork Desktop

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 -- 20 agents, 19 commands, 14 skills, and 7 MCP servers covering BGE/ATF/DTF precedent research, litigation strategy, adversarial analysis, legal drafting, and citation verification across all 26 Swiss cantons.

Claude Code CLI users: this repository is Cowork Desktop only. The CLI version is at fedec65/bettercallclaude-cli.

Overview

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

Key Features

  • Briefing sessions -- Complex queries trigger a collaborative intake phase with specialist panels, targeted questions, and structured execution plans before agents start working. Supports --resume for cross-session persistence.
  • Adversarial analysis -- Three-agent workflow: advocate builds the case, adversary challenges it, judicial analyst synthesizes using Swiss Erwagung methodology with probability scores.
  • Multi-agent workflows -- Predefined pipelines for due diligence, litigation prep, contract lifecycle, and real estate closings.
  • All 26 cantons -- Full cantonal coverage with court systems, citation formats, and MCP search via entscheidsuche.ch. Federal law is the default; mentioning a canton triggers cantonal mode.
  • Multi-language -- Automatic language detection for DE/FR/IT/EN with correct legal terminology and citation formats.
