## 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 skill | `src/features/builtin-skills/` | Create skill dir with SKILL.md |
| 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/Gemini 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 |
| Skill MCP | `src/features/skill-mcp-manager/` | MCP servers embedded in skills |
| Interactive terminal | `src/tools/interactive-bash/` | tmux session management |
| CLI installer | `src/cli/install.ts` | Interactive TUI installation |
| Doctor checks | `src/cli/doctor/checks/` | Health checks for environment |
| Shared utilities | `src/shared/` | Cross-cutting utilities |
| Slash commands | `src/hooks/auto-slash-command/` | Auto-detect and execute `/command` patterns |
| Ralph Loop | `src/hooks/ralph-loop/` | Self-referential dev loop until completion |

## 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
- **High temperature**: Don't use >0.3 for code-related agents
- **Broad tool access**: Prefer explicit `include` over unrestricted access
- **Sequential agent calls**: Use `background_task` for parallel execution
- **Heavy PreToolUse logic**: Slows every tool call
- **Self-planning for complex tasks**: Spawn planning agent (Prometheus) instead

## 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
- **Factory pattern**: Components created via `createXXX()` functions

## 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

```bash
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, rolling `next` draft release
- **publish.yml**: Manual workflow_dispatch, version bump, changelog, OIDC npm publish
- **sisyphus-agent.yml**: Agent-in-CI for automated issue handling via `@sisyphus-dev-ai` mentions

## COMPLEXITY HOTSPOTS

| `src/cli/config-manager.ts` | 669 | JSONC parsing, environment detection, installation |
| `src/auth/antigravity/fetch.ts` | 621 | Token refresh, URL rewriting, endpoint fallbacks |

## NOTES

- **Testing**: Bun native test (`bun test`), BDD-style `#given/#when/#then`, 360+ tests
- **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
- **JSONC support**: Config files support comments (`// comment`, `/* block */`) and trailing commas
- **Claude Code Compat**: Full compatibility layer for settings.json hooks, commands, skills, agents, MCPs
- **Skill MCP**: Skills can embed MCP server configs in YAML frontmatter
