Claude Code Second Brain Skills

A set of Claude Code skills for knowledge work: brand and voice, an MCP client, PPTX slides, Remotion video, SOPs and a skill creator

Skill

Medium risk

We rate an entry medium when the tool runs code, makes network calls or reads project files. Check what exactly it does before installing.

Why this level

  • Runs Python scripts and connects to external MCP servers with your keys
  • Creates files in the project and reads configuration

Install

Manual install

git clone https://github.com/coleam00/second-brain-skills.git
cp -r second-brain-skills/.claude/skills/* .claude/skills/

Copy all folders or only the ones you need. For a global install, copy into ~/.claude/skills/.

This is third-party code. Review the repository files before installing.

What it does

The set extends Claude Code beyond code into knowledge and content tasks, and each skill loads detailed instructions only when needed. The brand and voice skill assembles style and tone files that the presentation generator then uses for slides and carousels. The MCP client wraps external MCP servers and loads tool schemas on demand to avoid bloating context. Separate skills produce Remotion video, format runbooks and SOPs, and help you author new skills. It installs by copying the folders you need into the skills directory.

Who it is for. For people who run knowledge and content in Claude Code: writers, communications specialists and developers.

Good fit when

  • You need to connect external MCP servers without bloating context
  • You need to build slides or a carousel in your brand style
  • You need to write a runbook, SOP or how-to guide
  • You need to author your own Claude Code skill

Not a fit when

  • The task is only about code rather than knowledge and content
  • Your environment lacks Python or a separate Remotion project that some skills require

Example request

Turn this report into branded slides

Limitations

The MCP client and skill creator use Python scripts, the video skill runs in a separate Remotion project on Node, and the external MCP servers need their own keys. The repository states no license, which is worth considering for work use.

How to disable. Remove the skill folders from the project's .claude/skills/ directory or from ~/.claude/skills/.

Security check

  • Runs Python scripts and connects to external MCP servers with your keys
  • Creates files in the project and reads configuration

README in short

The README presents a set of skills that turn Claude Code into a second brain for knowledge work through progressive disclosure of context. It covers a brand and voice skill, an MCP client that loads tool schemas on demand, a presentation generator, a Remotion video skill, an SOP creator and a skill creator. Each one shows triggers, setup steps and example commands, and several ship Python scripts and config examples. Skills install by copying folders into the .claude/skills/ directory. A quick start section shows where to begin for each task.

# Skill Creator

This skill provides guidance for creating effective skills.

## About Skills

Skills are modular, self-contained packages that extend Claude's capabilities by providing specialized knowledge, workflows, and tools. Think of them as onboarding guides for specific domains or tasks: they turn Claude from a general-purpose agent into a specialized agent equipped with procedural knowledge that no model can fully possess.

### What Skills Provide

1. Specialized workflows, multi-step procedures for specific domains
2. Tool integrations, instructions for working with specific file formats or APIs
3. Domain expertise, company-specific knowledge, schemas, business logic
4. Bundled resources, scripts, references and assets for complex and repetitive tasks

## Core Principles

### Concise is key

The context window is a public good. Skills share it with everything else Claude needs: the system prompt, conversation history, other skills' metadata and the actual user request.

FAQ

Do I have to install all the skills?

No. You can copy only the folders you need, for example the SOP creator or the MCP client.

How do brand and presentations connect?

The brand and voice skill creates style and tone files, and the presentation generator draws colors, fonts and voice from them for the slides.
