Noahain's OpenCode Setup

AI coding agent configuration for OpenCode. Contains subagent definitions, skill packages, behavioral guidelines, and MCP server setup.

Features

• 8 specialized subagents — explore, git-agent, docs-fetcher, test-engineer, spec-verifier, code-reviewer, fast-coder, vibe-tester
• 101 skills — reusable packages for frontend, backend, design, debugging, DevOps, and more
• 7 plugins — superpowers, agent-skills, dcp, snip, notification, handoff, see-image
• 3 MCP servers — Context7 (docs), Chrome DevTools (browser automation), 21st.dev (UI components)
• RPD optimization mode — parallel tool calls, batched reads, no permission seeking

Subagents

Agent	Model	Access	Purpose
@fast-coder	deepseek/deepseek-v4-flash	bash	Simple/boilerplate coding
@vibe-tester	opencode-go/kimi-k2.7-code	bash (read-only)	Spec validation & gap analysis
@explore	deepseek/deepseek-v4-flash	bash (read-only)	Code/file search
@git-agent	deepseek/deepseek-v4-flash	bash (read-only)	Git operations
@docs-fetcher	deepseek/deepseek-v4-pro	none	Documentation lookup
@test-engineer	deepseek/deepseek-v4-pro	bash (read-only)	Build/test/lint
@spec-verifier	deepseek/deepseek-v4-pro	bash (read-only)	Spec compliance

Plugins

• superpowers — skill-based development workflow
• opencode-agent-skills — expanded skill library
• @tarquinen/opencode-dcp — deep context preservation
• opencode-snip — snippet management
• opencode-notification — system notifications
• opencode-handoff — session handoff
• opencode-see-image — screenshot viewing via vision model

Key Behavioral Guidelines (from AGENTS.md)

• Delegation — explore, docs-fetcher, git-agent, test-engineer, vibe-tester, spec-verifier, code-reviewer, fast-coder are the only things delegated. Main agent does reasoning/design/fixes.
• Ask before committing — git commits require explicit user approval.
• Verify before claiming — tests, lint, and typecheck must produce fresh evidence before marking anything done.
• Simplicity first — minimum code that solves the problem. No features, abstractions, or config that wasn't requested.
• RPD mode — collapse work into fewest turns, batch reads, skip optional verification.
• Surgical changes — touch only what's required, match existing style, clean up only your own mess.
• Subagent-Driven Development — vibe-tester → build → spec-verifier → code-reviewer pipeline.

Configuration

Edit opencode.json to:

• Add or remove subagents under agent
• Add plugins under plugin
• Configure MCP servers under mcp

MCP API keys (Context7 and 21st) are configured in opencode.json and should be populated before first use.
