Rulecatch SDK — Data skill for Claude Code

Rulecatch SDK

Official open-source packages for [Rulecatch](https://rulecatch.ai) — AI coding analytics, monitoring, and rule enforcement for Claude Code.

Track every AI coding session in real-time: tool calls, file edits, token usage, costs, and rule violations. Privacy-first with zero-knowledge encryption.

Packages

Package	Description	npm
`@rulecatch/ai-pooler`	CLI + hooks for tracking AI coding activity	
`@rulecatch/mcp-server`	MCP server — query violations and rules from Claude Code	

Quick Start

Monitor AI activity (no account needed)

npx @rulecatch/ai-pooler monitor --no-api-key

See what your AI coding assistant is doing in real-time — tool calls, file edits, tokens, costs. Zero setup.

Full setup (with dashboard)

# 1. Install and configure
npx @rulecatch/ai-pooler init

# 2. Start the live monitor
npx @rulecatch/ai-pooler monitor

# 3. (Optional) Add MCP server for in-IDE rule violations
# Add to ~/.claude/mcp.json:
# { "mcpServers": { "rulecatch": { "command": "npx", "args": ["-y", "@rulecatch/mcp-server"] } } }

What It Tracks

• Tool calls — every Read, Write, Edit, Bash, Grep, Glob with success/failure and I/O size
• Token usage — input/output tokens per model, running totals
• Cost — real-time cost estimation by model (Opus, Sonnet, Haiku)
• Code changes — lines added/removed via git diff
• Session timeline — start, end, duration, active time
• Rule violations — custom rules enforced across your team

Privacy

All personal data (file paths, emails, project names) is encrypted on your machine before it leaves. We use AES-256-GCM with PBKDF2 key derivation
