OVERVIEW

OpenCode plugin implementing Claude Code/AmpCode features. Multi-model agent orchestration (GPT-5.2, Claude, Gemini, Grok), LSP tools (11), AST-Grep search, MCP integrations (context7, websearch_exa, grep_app). "oh-my-zsh" for OpenCode.

WHERE TO LOOK

Task	Location	Notes
Add agent	src/agents/	Create .ts, add to builtinAgents in index.ts, update types.ts
Add hook	src/hooks/	Create dir with createXXXHook(), export from index.ts
Add tool	src/tools/	Dir with index/types/constants/tools.ts, add to builtinTools
Add MCP	src/mcp/	Create config, add to index.ts
LSP behavior	src/tools/lsp/	client.ts (connection), tools.ts (handlers)
AST-Grep	src/tools/ast-grep/	napi.ts for @ast-grep/napi binding
Google OAuth	src/auth/antigravity/	OAuth plugin for Google models
Config schema	src/config/schema.ts	Zod schema, run bun run build:schema after changes
Claude Code compat	src/features/claude-code-*-loader/	Command, skill, agent, mcp loaders
Background agents	src/features/background-agent/	manager.ts for task management
Interactive terminal	src/tools/interactive-bash/	tmux session management

CONVENTIONS

• Package manager: Bun only (bun run, bun build, bunx)
• Types: bun-types (not @types/node)
• Build: Dual output - bun build (ESM) + tsc --emitDeclarationOnly
• Exports: Barrel pattern - export * from "./module" in index.ts
• Directory naming: kebab-case (ast-grep/, claude-code-hooks/)
• Tool structure: index.ts, types.ts, constants.ts, tools.ts, utils.ts
• Hook pattern: createXXXHook(input: PluginInput) returning event handlers
• Test style: BDD comments #given, #when, #then (same as AAA)

ANTI-PATTERNS (THIS PROJECT)

• npm/yarn: Use bun exclusively
• @types/node: Use bun-types
• Bash file ops: Never mkdir/touch/rm/cp/mv for file creation in code
• Direct bun publish: GitHub Actions workflow_dispatch only (OIDC provenance)
• Local version bump: Version managed by CI workflow
• Year 2024: NEVER use 2024 in code/prompts (use current year)
• Rush completion: Never mark tasks complete without verification
• Over-exploration: Stop searching when sufficient context found

UNIQUE STYLES

• Platform: Union type "darwin" | "linux" | "win32" | "unsupported"
• Optional props: Extensive ? for optional interface properties
• Flexible objects: Record<string, unknown> for dynamic configs
• Error handling: Consistent try/catch with async/await
• Agent tools: tools: { include: [...] } or tools: { exclude: [...] }
• Temperature: Most agents use 0.1 for consistency
• Hook naming: createXXXHook function convention

AGENT MODELS

Agent	Model	Purpose
Sisyphus	anthropic/claude-opus-4-5	Primary orchestrator
oracle	openai/gpt-5.2	Strategic advisor, code review
librarian	anthropic/claude-sonnet-4-5	Multi-repo analysis, docs
explore	opencode/grok-code	Fast codebase exploration
frontend-ui-ux-engineer	google/gemini-3-pro-preview	UI generation
document-writer	google/gemini-3-pro-preview	Technical docs
multimodal-looker	google/gemini-3-flash	PDF/image analysis

COMMANDS

bun run typecheck      # Type check
bun run build          # ESM + declarations + schema
bun run rebuild        # Clean + Build
bun run build:schema   # Schema only
bun test               # Run tests

DEPLOYMENT

GitHub Actions workflow_dispatch only

1. Never modify package.json version locally
2. Commit & push changes
3. Trigger publish workflow: gh workflow run publish -f bump=patch

Critical: Never bun publish directly. Never bump version locally.

CI PIPELINE

• ci.yml: Parallel test/typecheck, build verification, auto-commit schema on master
• publish.yml: Manual workflow_dispatch, version bump, changelog, OIDC npm publish

NOTES

• Testing: Bun native test (bun test), BDD-style #given/#when/#then
• OpenCode: Requires >= 1.0.150
• Multi-lang docs: README.md (EN), README.ko.md (KO), README.ja.md (JA), README.zh-cn.md (ZH-CN)
• Config: ~/.config/opencode/oh-my-opencode.json (user) or .opencode/oh-my-opencode.json (project)
• Trusted deps: @ast-grep/cli, @ast-grep/napi, @code-yeongyu/comment-checker
