Installation

Some skills like browser-tools and web-search are redundant for fully featured coding agents like claude or codex - so they should be skipped for them. A minimal agent like Pi, needs them though.

Claude Code

Claude Code only looks one level deep for SKILL.md files, so each skill folder must be directly under the skills directory. Clone the repo somewhere, then symlink individual skills:

git clone https://github.com/SeanPedersen/agent-skills
cd agent-skills
# Symlink all skills (user-level)
mkdir -p ~/.claude/skills
for skill in "$(pwd)"/*/; do
  name=$(basename "$skill")
  [[ "$name" == "browser-tools" || "$name" == "web-search" ]] && continue
  [ -f "$skill/SKILL.md" ] && ln -sf "$skill" ~/.claude/skills/$name
done
# Or project-level
mkdir -p .claude/skills
for skill in "$(pwd)"/*/; do
  name=$(basename "$skill")
  [[ "$name" == "browser-tools" || "$name" == "web-search" ]] && continue
  [ -f "$skill/SKILL.md" ] && ln -sf "$skill" .claude/skills/$name
done

Codex CLI

Codex also expects skill folders directly under the skills directory. Symlink each skill:

git clone https://github.com/SeanPedersen/agent-skills
cd agent-skills
mkdir -p ~/.codex/skills
for skill in "$(pwd)"/*/; do
  name=$(basename "$skill")
  [[ "$name" == "browser-tools" || "$name" == "web-search" ]] && continue
  [ -f "$skill/SKILL.md" ] && ln -sf "$skill" ~/.codex/skills/$name
done

Skill Format

Each skill follows the Claude Code skill format:

---
name: skill-name
description: Short description shown to agent
---
# Instructions
Detailed instructions here...
Helper files available at: {baseDir}/

The {baseDir} placeholder is replaced with the skill's directory path at runtime.

Requirements

Some skills require additional setup. Generally, the agent will walk you through that. But if not:

blog-post: Requires Python 3.10+ and uv. Also requires the web-search skill.
browser-tools: Requires Chrome and Node.js. Run npm install in the skill directory.
web-search: Requires Python 3.10+ and uv. No API key needed.
free-domain-search: Requires Python 3.10+, uv, and whois CLI tool.
youtube-transcript: Requires Python 3.10+ and uv. No API key needed.
