Claude Code Second Brain Skills A collection of custom skills that turn Claude Code into a second brain for knowledge work. These skills demonstrate progressive disclosure of context - there's no magic, just structured knowledge that makes Claude hyper-capable for specific tasks. What This Is Most people think of Claude Code as a tool for writing and debugging code. These skills extend it into a system for capturing and operationalizing knowledge: External integrations - Connect to MCP servers (Zapier, GitHub, etc.) without context bloat Video creation - Programmatic videos with Remotion and React Presentations - Professional slides and LinkedIn carousels with your brand styling Documentation - Runbooks, SOPs, and technical docs that people actually follow Skill development - Creating new skills to extend Claude's capabilities further Brand consistency - Define your voice and visual identity once, use everywhere The system works through progressive disclosure: Claude only loads detailed instructions when needed, keeping context efficient while maintaining deep expertise for each domain.

Grades come from a rule-based scan built on the SlowMist agent-security taxonomy, covering 11 red-flag categories including credential harvesting, data exfiltration, and curl | sh installers. It is a first-layer scan, not a manual audit — we say so rather than overstate it.
The scale of the problem is documented independently: Liu et al. (2026), in a study of 31,132 agent skills, report that 26.1% contain security vulnerabilities. Our own full-catalog census is published as a citable open dataset.
