Manual (single skill)

# Symlink a single skill
ln -s ~/CODE/agent-skills/skills/typescript-strict-patterns ~/.claude/skills/typescript-strict-patterns

# Or copy it
cp -r ~/CODE/agent-skills/skills/typescript-strict-patterns ~/.claude/skills/

Skills are picked up automatically by Claude Code based on their globs frontmatter.

Format

Each skill follows the Agent Skills spec — a SKILL.md file with YAML frontmatter (name, description, globs) and markdown instructions.

Creating Skills

Quick Start

my-skill/
├── SKILL.md          # Required: frontmatter + instructions
├── README.md         # Required: development notes, design decisions, testing history
└── REFERENCE.md      # Optional: detailed reference material (>100 lines)

SKILL.md Template

---
name: my-skill-name     # lowercase, hyphens, max 64 chars, must match directory
description: What it does and when to use it. Include trigger keywords. (max 1024 chars)
# Optional fields per agentskills.io spec:
compatibility: claude-code, cursor
license: MIT
metadata:
  source: https://github.com/your-org/your-repo
  version: "1.0"

# My Skill Name

[Instructions here — keep under 500 lines]

See [REFERENCE.md](REFERENCE.md) for details.

Note: Reference files over 100 lines should include a table of contents.

Key Principles

1. Be concise — Only add what Claude doesn't already know
2. Progressive disclosure — Overview in SKILL.md, details in referenced files
3. Third person — "Processes files" not "I help you process files"
4. One level deep — Reference files directly from SKILL.md, avoid nesting
5. Use checklists — Multi-step workflows benefit from copy-paste checklists
6. Test across models — Haiku may need more guidance than Opus

Skill Composition

Skills can reference other skills by name in their instructions:

## Committing Your Fix

When ready to commit, use the **commit-notation** skill:
- Bugfixes use `B` intention
- Risk level depends on test coverage

Claude loads both skills when context matches. No formal import system — just mention by name.

Development

Adding a changeset

When making changes, add a changeset to describe your change:

pnpm changeset

Edit the created file to set the bump type (patch, minor, or major) and describe the change.

Releasing

pnpm run version   # bumps version, writes changelog, syncs all metadata files
pnpm run release   # commits and tags — then push with: git push --follow-tags
