second-brain-starter

A skill for Claude Code that generates a personalized Product Requirements Document (PRD) for building your own AI second brain - a proactive, persistent AI assistant that knows your context, remembers across sessions, and keeps you informed.

What This Does

You fill out a simple requirements template describing your tools, workflow, and preferences. Then Claude Code generates a phased build plan tailored to your setup - covering memory, integrations, skills, a proactive heartbeat, chat interface, and security hardening.

The generated PRD gives you (or your coding agent) a step-by-step blueprint for building a second brain that:

• Remembers across sessions - decisions, preferences, context, all in markdown files
• Connects to your platforms - Gmail, Slack, Calendar, Asana, Linear, GitHub, and more
• Proactively monitors your email, calendar, and tasks every 30 minutes
• Chats with you through Slack (or Discord, or any messaging platform)
• Searches months of memory with hybrid keyword + semantic search
• Drafts replies in your voice using RAG on your past messages
• Tracks habits with daily nudges inspired by Atomic Habits
