*Transform your AI assistant into a manager capable of delegating complex tasks to specialized sub-agents, running searches in the background, and managing multi-step workflows with ease.*
> **💡 Tip: Models are fully customizable.** The installer sets sensible defaults, but you can assign *any* model to *any* agent. Edit `~/.config/opencode/oh-my-opencode-slim.json` to override models, adjust reasoning effort, or disable agents entirely. See [Configuration](#configuration) for details.
**Alternative: Ask any coding agent**
Paste this into Claude Code, AmpCode, Cursor, or any coding agent:

### For LLM Agents
1. **User Prompt**: "Refactor the auth logic and update the docs."
2. **Orchestrator**: Creates a TODO list.
3. **Delegation**:
- Launches an `@explorer` background task to find all auth-related files.
- Launches a `@librarian` task to check the latest documentation for the auth library used.
4. **Integration**: Once background results are ready, the Orchestrator delegates to `@fixer` to perform the refactor efficiently.

### Primary vs Subagents
Primary agents appear in the OpenCode UI selector, while subagents are hidden from the UI and intended for delegation through `background_task`.
**Primary agents (UI):**
- OpenCode built-ins: `Build`, `Plan` (disabled by the installer by default)
- Plugin primary: `orchestrator`
**Subagents (background_task):** `explorer`, `librarian`, `oracle`, `designer`, `fixer`
The `background_task` tool lists only subagents. If the UI list looks stale after changes, restart OpenCode.

## Meet the Pantheon
> **The Orchestrator** was born when the first codebase collapsed under its own complexity. Neither god nor mortal would claim responsibility - so The Orchestrator emerged from the void, forging order from chaos. They don't merely command armies; they fight alongside them. Every line of code passes through their hands before they decide which lesser deity deserves a piece of the puzzle.
**Role:** `Supreme executor, delegator, and overseer`
**Model:** `google/claude-opus-4-5-thinking`
**Prompt:** [src/agents/orchestrator.ts](src/agents/orchestrator.ts)
Write and execute code, orchestrate multi-agent workflows, parse the unspoken from the spoken, summon specialists mid-battle. *Shape reality directly - and assign realms to others when the universe grows too vast.*
> **The Explorer** is an immortal wanderer who has traversed the corridors of a million codebases since the dawn of programming. Cursed with the gift of eternal curiosity, they cannot rest until every file is known, every pattern understood, every secret revealed. Legends say they once searched the entire internet in a single heartbeat. They are the wind that carries knowledge, the eyes that see all, the spirit that never sleeps.
**Role:** `Codebase reconnaissance`
**Model:** `google/gemini-3-flash`
**Prompt:** [src/agents/explorer.ts](src/agents/explorer.ts)
Regex search, AST pattern matching, file discovery, parallel exploration. *Read-only: they chart the territory; others conquer it.*
> **The Oracle** stands at the crossroads of every architectural decision. They have walked every road, seen every destination, know every trap that lies ahead. When you stand at the precipice of a major refactor, they are the voice that whispers which way leads to ruin and which way leads to glory. They don't choose for you - they illuminate the path so you can choose wisely.
**Role:** `Strategic advisor and debugger of last resort`
**Model:** `openai/gpt-5.2-codex`
**Prompt:** [src/agents/oracle.ts](src/agents/oracle.ts)
Root cause analysis, architecture review, debugging guidance, tradeoff analysis. *Read-only: Oracles advise; they don't intervene.*
> **The Librarian** was forged when humanity realized that no single mind could hold all knowledge. They are the weaver who connects disparate threads of information into a tapestry of understanding. They traverse the infinite library of human knowledge, gathering insights from every corner and binding them into answers that transcend mere facts. What they return is not information - it's understanding.
**Role:** `External knowledge retrieval`
**Model:** `google/gemini-3-flash`
**Prompt:** [src/agents/librarian.ts](src/agents/librarian.ts)
Documentation lookup, GitHub code search, library research, best practice retrieval. *Read-only: they fetch wisdom; implementation is for others.*
> **The Designer** is an immortal guardian of beauty in a world that often forgets it matters. They have seen a million interfaces rise and fall, and they remember which ones were remembered and which were forgotten. They carry the sacred duty to ensure that every pixel serves a purpose, every animation tells a story, every interaction delights. Beauty is not optional - it's essential.
**Role:** `UI/UX implementation and visual excellence`
**Model:** `google/gemini-3-flash`
**Prompt:** [src/agents/designer.ts](src/agents/designer.ts)
Modern responsive design, CSS/Tailwind mastery, micro-animations, component architecture. *Visual excellence over code perfection - beauty is the priority.*
> **The Fixer** is the last of a lineage of builders who once constructed the foundations of the digital world. When the age of planning and debating began, they remained - the ones who actually build. They carry the ancient knowledge of how to turn thought into thing, how to transform specification into implementation. They are the final step between vision and reality.
**Role:** `Fast implementation specialist`
**Model:** `google/gemini-3-flash`
**Prompt:** [src/agents/fixer.ts](src/agents/fixer.ts)
Code implementation, refactoring, testing, verification. *Execute the plan - no research, no delegation, no planning.*
**Watch your agents work in real-time.** When the Orchestrator launches sub-agents or initiates background tasks, new tmux panes automatically spawn showing each agent's live progress. No more waiting in the dark.
#### Why This Matters
| Without Tmux Integration | With Tmux Integration |
|--------------------------|----------------------|
| Fire off a background task, wait anxiously | See the agent thinking, searching, coding |
| "Is it stuck or just slow?" | Watch tool calls happen in real-time |
| Results appear out of nowhere | Follow the journey from question to answer |
| Debug by guessing | Debug by observation |
#### What You Get
- **Live Visibility**: Each sub-agent gets its own pane showing real-time output
- **Auto-Layout**: Tmux automatically arranges panes using your preferred layout
- **Auto-Cleanup**: Panes close when agents finish, layout rebalances
- **Zero Overhead**: Works with OpenCode's built-in `task` tool AND our `background_task` tool
#### Quick Setup
> ⚠️ **Temporary workaround:** Start OpenCode with `--port 4096` to enable tmux integration. This is required until the upstream issue is resolved.
1. **Enable tmux integration** in `oh-my-opencode-slim.json` (see [Plugin Config](#plugin-config-oh-my-opencode-slimjson)).
2. **Run OpenCode inside tmux with port 4096**:
```bash
tmux
opencode --port 4096
```
#### Layout Options
| Layout | Description |
|--------|-------------|
| `main-vertical` | Your session on the left (60%), agents stacked on the right |
| `main-horizontal` | Your session on top (60%), agents stacked below |
| `tiled` | All panes in equal-sized grid |
| `even-horizontal` | All panes side by side |
| `even-vertical` | All panes stacked vertically |
*See the [Option Reference](#option-reference) for detailed configuration.*

| Tool | Description |
|------|-------------|
| `antigravity_quota` | Check API quota for all Antigravity accounts (compact view with progress bars) |
---
### Background Tasks
The plugin provides tools to manage asynchronous work:
| Tool | Description |
|------|-------------|
| `background_task` | Launch an agent in a new session (`sync=true` blocks, `sync=false` runs in background) |
| `background_output` | Fetch the result of a background task by ID |
| `background_cancel` | Abort running tasks |
---
### LSP Tools
Language Server Protocol integration for code intelligence:
| Tool | Description |
|------|-------------|
| `lsp_goto_definition` | Jump to symbol definition |
| `lsp_find_references` | Find all usages of a symbol across the workspace |
| `lsp_diagnostics` | Get errors/warnings from the language server |
| `lsp_rename` | Rename a symbol across all files |
---
### Code Search Tools
Fast code search and refactoring:
| Tool | Description |
|------|-------------|
| `grep` | Fast content search using ripgrep |
| `ast_grep_search` | AST-aware code pattern matching (25 languages) |
| `ast_grep_replace` | AST-aware code refactoring with dry-run support |
---
## 🧩 Skills
Skills are specialized capabilities that agents can use. Each agent has a default set of skills, which you can override in the agent config.
### Available Skills
| Skill | Description |
|-------|-------------|
| `yagni-enforcement` | Code complexity analysis and YAGNI enforcement |
| `playwright` | Browser automation via Playwright MCP |
### Default Skill Assignments
| Agent | Default Skills |
|-------|----------------|
| `orchestrator` | `*` (all skills) |
| `designer` | `playwright` |
| `oracle` | none |
| `librarian` | none |
| `explorer` | none |
| `fixer` | none |
### YAGNI Enforcement
**The Minimalist's sacred truth: every line of code is a liability.**
Use after major refactors or before finalizing PRs. Identifies unnecessary complexity, challenges premature abstractions, estimates LOC reduction, and enforces minimalism.
### Playwright Integration
**Browser automation for visual verification and testing.**
- **Browser Automation**: Full Playwright capabilities (browsing, clicking, typing, scraping).
- **Screenshots**: Capture visual state of any web page.
- **Sandboxed Output**: Screenshots saved to session subdirectory (check tool output for path).
### Customizing Agent Skills
Override skills per-agent in your [Plugin Config](#plugin-config-oh-my-opencode-slimjson):
```json
{
"agents": {
"orchestrator": {
"skills": ["*"]
},
"designer": {
"skills": ["playwright"]
}
}
}
```
