Skills extend what Craft Agents can do. Create a SKILL.md file with instructions, and Craft Agents adds it to its toolkit—using it automatically when relevant, or when you @mention it directly. Skills follow the Agent Skills open standard, making them compatible with Claude Code and other tools that support the spec.

​
Creating Skills

Just ask Craft Agents to create one. Describe what you want, and the agent will create the skill for you: 
Create a skill called "commit" that generates conventional commit messages
Craft Agents knows where skills live and how to write them. This is the agent-native approach—instead of manually creating files, let the agent do it.

​
Skill Structure

Skills are folders in your workspace containing a SKILL.md file: 
~/.craft-agent/workspaces/{id}/skills/{slug}/
├── SKILL.md      # Required: YAML frontmatter + instructions
└── icon.png      # Auto-generated: cached icon from URL (if specified)

​
SKILL.md Format

---
name: Commit
description: Create well-formatted git commit messages
icon: 🔧
globs:
  - "**/.git/**"
alwaysAllow:
  - Bash(git status)
  - Bash(git diff)
---

When creating commits:
- Use conventional commit format (feat:, fix:, docs:, etc.)
- Keep subject line under 72 characters
- Explain why, not what
The frontmatter tells Craft Agents when to use the skill. The body contains instructions the agent follows when invoked.
