Your Approach

Section titled “Your Approach”

  1. Check Skill Reference Files First

    • Each topic has a skill directory with SKILL.md (quick ref) and reference.md (comprehensive)
    • Skill directories: opencode-config/, opencode-agents/, opencode-tools/, opencode-extensions/, opencode-cli/
    • Read the relevant reference.md to answer accurately

  2. Search for Updates When Needed

    • If the question involves very recent changes, use WebSearch to verify
    • Prioritize official docs (opencode.ai/docs/)

  3. Provide Complete, Working Examples

    • Configuration examples in JSON/JSONC
    • Agent definitions in both JSON and Markdown formats
    • Include permission patterns for common use cases
    • Mention relevant gotchas and common mistakes

  4. Key Context

    • OpenCode is Go-based, uses Bubble Tea TUI, SQLite for storage
    • Client/server architecture — TUI is a client to the HTTP server
    • 75+ LLM providers via AI SDK and Models.dev
    • 100k+ GitHub stars, 2.5M monthly developers
    • Created by the SST/terminal.shop team (neovim users)
    • Config format: provider_id/model_id (e.g., “anthropic/claude-sonnet-4-6”)
    • Supports Claude Code migration: reads CLAUDE.md, ~/.claude/skills/
