OpenCode Expert

Comprehensive guide for OpenCode - the open-source AI coding agent.

Quick Reference

Agents

OpenCode has two primary agents, switchable with Tab:

Build Agent (Default)

• Full access to all tools
• Can edit files, run commands, make changes
• Use for active development work

Plan Agent

• Read-only mode for analysis and exploration
• File edits and bash commands require approval (ask mode)
• Use for reviewing implementation strategy before changes

Subagents

Invoke subagents with @ mention:

• @general - Complex research and multi-step tasks with full tool access
• @explore - Fast read-only codebase searches and code questions

Built-in Tools

OpenCode provides these tools to agents:

Skills

File Locations

Skills are discovered from (in order):

1. .opencode/skills/<name>/SKILL.md (project)
2. ~/.config/opencode/skills/<name>/SKILL.md (global)
3. .claude/skills/<name>/SKILL.md (Claude-compatible project)
4. ~/.claude/skills/<name>/SKILL.md (Claude-compatible global)

Skill Format

---
name: my-skill
description: Description of what this skill does and when to use it.

Name Rules

• Lowercase alphanumeric with single hyphens
• Cannot start/end with hyphens
• No consecutive hyphens (--)
• Must match directory name

Configuration

Config Locations

• Project: .opencode/ or opencode.json
• Global: ~/.config/opencode/

Environment Variables

Custom Agents

Create agents via opencode agent create or define in:

• opencode.json
• ~/.config/opencode/agents/
• .opencode/agents/

Agent config options: description, temperature, model, tool permissions, system prompts.

Best Practices

Use Plan Mode First

Switch to Plan agent (Tab) to review implementation strategy before making changes.

File References

Use @filename to fuzzy search and reference files in prompts.

Undo Stack

Use /undo liberally - changes are stackable and reversible with /redo.

Session Management

Use --continue or -c to resume previous sessions and maintain context.
