## 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.

## TDD (Test-Driven Development)

**MANDATORY for new features and bug fixes.** Follow RED-GREEN-REFACTOR:

```
1. RED    - Write failing test first (test MUST fail)
2. GREEN  - Write MINIMAL code to pass (nothing more)
3. REFACTOR - Clean up while tests stay GREEN
4. REPEAT - Next test case
```

| Phase | Action | Verification |
|-------|--------|--------------|
| **RED** | Write test describing expected behavior | `bun test` → FAIL (expected) |
| **GREEN** | Implement minimum code to pass | `bun test` → PASS |
| **REFACTOR** | Improve code quality, remove duplication | `bun test` → PASS (must stay green) |

**Rules:**
- NEVER write implementation before test
- NEVER delete failing tests to "pass" - fix the code
- One test at a time - don't batch
- Test file naming: `*.test.ts` alongside source

## CONVENTIONS

- **Package manager**: Bun only (`bun run`, `bun build`, `bunx`)
- **Types**: bun-types (not @types/node)
- **Build**: `bun build` (ESM) + `tsc --emitDeclarationOnly`
- **Exports**: Barrel pattern in index.ts; explicit named exports for tools/hooks
- **Naming**: kebab-case directories, createXXXHook/createXXXTool factories
- **Testing**: BDD comments `#given`, `#when`, `#then` (same as AAA); TDD workflow (RED-GREEN-REFACTOR)
- **Temperature**: 0.1 for code agents, max 0.3

## 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 `sisyphus_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 | Default Model | Purpose |
|-------|-------|---------|
| Sisyphus | anthropic/claude-opus-4-5 | Primary orchestrator |
| oracle | openai/gpt-5.2 | Read-only consultation. High-IQ debugging, architecture |
| 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
