This skill guides you through creating high-quality, reusable OpenCode agent skills.

Best Practices

1. Naming: Use lowercase-alphanumeric-with-hyphens. The name MUST match the directory name.
2. Description & Triggers:
   • Be precise. The agent uses this description to decide when to load the skill.
   • CRITICAL: Always include common "catchphrases" or triggers in the description to help the agent identify when to use the skill.
   • Example description: "Skill for analyzing logs. Triggers: 'check the logs', 'what happened in the logs', 'analyze errors'."
3. Frontmatter: Always include name and description. license and compatibility are recommended.

Steps to Create a Skill

1. Identify the behavior: Define exactly what reusable logic you want to encapsulate.

2. Fetch Documentation: Use the webfetch tool to read https://opencode.ai/docs/skills/ to ensure the skill is created using the most up-to-date syntax and rules.

3. Determine Location: Use the question tool to ask the user if the skill should be created locally (project-level) or globally (user-level).

   • Local: .opencode/skill/ or .claude/skills/ (default to .claude/skills/ if the project uses it).
   • Global: ~/.config/opencode/skill/ or ~/.claude/skills/ (default to ~/.claude/skills/).

4. Scaffold:

   • Create the skill directory in the chosen location.
   • Create a references/ subfolder if complex documentation is needed.

5. Initialize: Use the SKILL_TEMPLATE.md to create the new SKILL.md.

6. Draft Instructions: Write the "how-to" for the agent. Use headers for clarity (e.g., ## Steps, ## Guidelines).

7. Verify: Ensure the frontmatter follows YAML standards and the name follows the regex ^[a-z0-9]+(-[a-z0-9]+)*$.

Templates

Use the standard template from this skill's references/ directory as a base.
