This lesson is a reference sheet for the concepts used in this course.

Official documentation

• OpenCode documentation: https://opencode.ai/docs
• Agents: https://opencode.ai/docs/agents
• Skills: https://opencode.ai/docs/skills
• Providers: https://opencode.ai/docs/providers
• Permissions: https://opencode.ai/docs/permissions
• CLI: https://opencode.ai/docs/cli
• Instructions / AGENTS.md: https://opencode.ai/docs/instructions

AGENTS.md

Use AGENTS.md for persistent project guidance such as:

• Build commands
• Architecture notes
• Code conventions
• Verification requirements

The official documentation recommends committing project AGENTS.md files to Git.

Agents

OpenCode documents:

• Primary agents
• Subagents
• Custom Markdown agents
• Agent-specific models
• Agent-specific permissions

Project agents are stored under:

.opencode/agents/

Global agents are stored under:

~/.config/opencode/agents/

A Markdown agent can use frontmatter such as:

---
description: Reviews code
mode: subagent
---

The filename becomes the agent name.

Skills

Project skills are stored under:

.opencode/skills/<name>/SKILL.md

Skills are loaded on demand.

Providers

Use /connect to connect a provider.

Use the model picker/current documentation to see available models.

OpenCode documents support for many providers and local models; exact availability changes over time.

Permissions

The documented permission concepts include:

allow
ask
deny

Use least privilege.

Version note

OpenCode is actively developed. Configuration syntax can evolve.

If your installed version differs from an example in this course:

1. Run the relevant --help command.
2. Check the current official OpenCode documentation.
3. Prefer the schema/documentation for your installed version.

This course intentionally teaches the concepts separately from version-specific configuration details.
