+## Tmux Integration
+
+Run background subagents in separate tmux panes for **visual multi-agent execution**. See your agents working in parallel, each in their own terminal pane.
+
+**Enable tmux integration** via `tmux` in `oh-my-opencode.json`:
+
+```json
+{
+  "tmux": {
+    "enabled": true,
+    "layout": "main-vertical",
+    "main_pane_size": 60,
+    "main_pane_min_width": 120,
+    "agent_pane_min_width": 40
+  }
+}
+```
+
+| Option | Default | Description |
+|--------|---------|-------------|
+| `enabled` | `false` | Enable tmux subagent pane spawning. Only works when running inside an existing tmux session. |
+| `layout` | `main-vertical` | Tmux layout for agent panes. See [Layout Options](#layout-options) below. |
+| `main_pane_size` | `60` | Main pane size as percentage (20-80). |
+| `main_pane_min_width` | `120` | Minimum width for main pane in columns. |
+| `agent_pane_min_width` | `40` | Minimum width for each agent pane in columns. |
+
+### Layout Options
+
+| Layout | Description |
+|--------|-------------|
+| `main-vertical` | Main pane left, agent panes stacked on right (default) |
+| `main-horizontal` | Main pane top, agent panes stacked bottom |
+| `tiled` | All panes in equal-sized grid |
+| `even-horizontal` | All panes in horizontal row |
+| `even-vertical` | All panes in vertical stack |
+
+### Requirements
+
+1. **Must run inside tmux**: The feature only activates when OpenCode is already running inside a tmux session
+2. **Tmux installed**: Requires tmux to be available in PATH
+3. **Server mode**: OpenCode must run with `--port` flag to enable subagent pane spawning
+
+### How It Works
+
+When `tmux.enabled` is `true` and you're inside a tmux session:
+- Background agents (via `delegate_task(run_in_background=true)`) spawn in new tmux panes
+- Each pane shows the subagent's real-time output
+- Panes are automatically closed when the subagent completes
+- Layout is automatically adjusted based on your configuration
+
+### Running OpenCode with Tmux Subagent Support
+
+To enable tmux subagent panes, OpenCode must run in **server mode** with the `--port` flag. This starts an HTTP server that subagent panes connect to via `opencode attach`.
+
+**Basic setup**:
+```bash
+# Start tmux session
+tmux new -s dev
+
+# Run OpenCode with server mode (port 4096)
+opencode --port 4096
+
+# Now background agents will appear in separate panes
+```
+
+**Recommended: Shell Function**
+
+For convenience, create a shell function that automatically handles tmux sessions and port allocation. Here's an example for Fish shell:
+
+```fish
+# ~/.config/fish/config.fish
+function oc
+    set base_name (basename (pwd))
+    set path_hash (echo (pwd) | md5 | cut -c1-4)
+    set session_name "$base_name-$path_hash"
+    
+    # Find available port starting from 4096
+    function __oc_find_port
+        set port 4096
+        while test $port -lt 5096
+            if not lsof -i :$port >/dev/null 2>&1
+                echo $port
+                return 0
+            end
+            set port (math $port + 1)
+        end
+        echo 4096
+    end
+    
+    set oc_port (__oc_find_port)
+    set -x OPENCODE_PORT $oc_port
+    
+    if set -q TMUX
+        # Already inside tmux - just run with port
+        opencode --port $oc_port $argv
+    else
+        # Create tmux session and run opencode
+        set oc_cmd "OPENCODE_PORT=$oc_port opencode --port $oc_port $argv; exec fish"
+        if tmux has-session -t "$session_name" 2>/dev/null
+            tmux new-window -t "$session_name" -c (pwd) "$oc_cmd"
+            tmux attach-session -t "$session_name"
+        else
+            tmux new-session -s "$session_name" -c (pwd) "$oc_cmd"
+        end
+    end
+    
+    functions -e __oc_find_port
+end
+```
+
+**Bash/Zsh equivalent**:
+
+```bash
+# ~/.bashrc or ~/.zshrc
+oc() {
+    local base_name=$(basename "$PWD")
+    local path_hash=$(echo "$PWD" | md5sum | cut -c1-4)
+    local session_name="${base_name}-${path_hash}"
+    
+    # Find available port
+    local port=4096
+    while [ $port -lt 5096 ]; do
+        if ! lsof -i :$port >/dev/null 2>&1; then
+            break
+        fi
+        port=$((port + 1))
+    done
+    
+    export OPENCODE_PORT=$port
+    
+    if [ -n "$TMUX" ]; then
+        opencode --port $port "$@"
+    else
+        local oc_cmd="OPENCODE_PORT=$port opencode --port $port $*; exec $SHELL"
+        if tmux has-session -t "$session_name" 2>/dev/null; then
+            tmux new-window -t "$session_name" -c "$PWD" "$oc_cmd"
+            tmux attach-session -t "$session_name"
+        else
+            tmux new-session -s "$session_name" -c "$PWD" "$oc_cmd"
+        fi
+    fi
+}
+```
+
+**How subagent panes work**:
+
+1. Main OpenCode starts HTTP server on specified port (e.g., `http://localhost:4096`)
+2. When a background agent spawns, Oh My OpenCode creates a new tmux pane
+3. The pane runs: `opencode attach http://localhost:4096 --session <session-id>`
+4. Each subagent pane shows real-time streaming output
+5. Panes are automatically closed when the subagent completes
+
+**Environment variables**:
+
+| Variable | Description |
+|----------|-------------|
+| `OPENCODE_PORT` | Default port for the HTTP server (used if `--port` not specified) |
+
+### Server Mode Reference
+
+OpenCode's server mode exposes an HTTP API for programmatic interaction:
+
+```bash
+# Standalone server (no TUI)
+opencode serve --port 4096
+
+# TUI with server (recommended for tmux integration)
+opencode --port 4096
+```
+
+| Flag | Default | Description |
+|------|---------|-------------|
+| `--port` | `4096` | Port for HTTP server |
+| `--hostname` | `127.0.0.1` | Hostname to listen on |
+
+For more details, see the [OpenCode Server documentation](https://opencode.ai/docs/server/).

-delegate_task(category="business-logic", prompt="Design the payment processing flow")
+1. User-configured model (in oh-my-opencode.json)
+2. Category's built-in default (if you add category to config)
+3. System default model (from opencode.json)
+```
 
-// Or target a specific agent directly
+**Example Problem:**
+
+```json
+// opencode.json
+{ "model": "anthropic/claude-sonnet-4-5" }
+
+// oh-my-opencode.json (empty categories section)
+{}
+
+// Result: ALL categories use claude-sonnet-4-5 (wasteful!)
+// - quick tasks use Sonnet instead of Haiku (expensive)
+// - ultrabrain uses Sonnet instead of GPT-5.2 (inferior reasoning)
+// - visual tasks use Sonnet instead of Gemini (suboptimal for UI)
+```
+
+### Recommended Configuration
+
+**To use optimal models for each category, add them to your config:**
+
+```json
+{
+  "categories": {
+    "visual-engineering": { 
+      "model": "google/gemini-3-pro-preview"

 YOU MUST LEVERAGE ALL AVAILABLE AGENTS / **CATEGORY + SKILLS** TO THEIR FULLEST POTENTIAL.
 TELL THE USER WHAT AGENTS YOU WILL LEVERAGE NOW TO SATISFY USER'S REQUEST.
 
-## AGENTS / **CATEGORY + SKILLS** UTILIZATION PRINCIPLES (by capability, not by name)
-- **Codebase Exploration**: Spawn exploration agents using BACKGROUND TASKS for file patterns, internal implementations, project structure
-- **Documentation & References**: Use librarian-type agents via BACKGROUND TASKS for API references, examples, external library docs
-- **Planning & Strategy**: NEVER plan yourself - ALWAYS spawn the Plan agent for work breakdown
-  - MUST invoke: \`delegate_task(subagent_type="plan", prompt="<gathered context + user request>")\`
-  - In your prompt to the Plan agent, ASK it to recommend which CATEGORY + SKILLS / AGENTS to leverage for implementation.
-  - IF IMPLEMENT TASK, MUST ADD TODO NOW: "Consult Plan agent via delegate_task(subagent_type='plan') for work breakdown with category + skills recommendations"
-- **High-IQ Reasoning**: Leverage specialized agents for architecture decisions, code review, strategic planning
-- **SPECIAL TASKS COVERED WITH CATEGORY + LOAD_SKILLS**: Delegate to specialized agents with category+skills for design and implementation, as following guide:
-  - CATEGORY + SKILL GUIDE
-    - MUST PASS \`load_skills\` FOR REQUIRED_SKILLS. MUST USE \`load_skills\` FOR REQUIRED_SKILLS.
-    - Simple project setup -> delegate_task(category="unspecified-low", load_skills=[{project-setup-skill}])
-    - Super Complex Server Workflow Implementation -> delegate_task(category="ultrabrain", load_skills=["terraform-master"], ...)
-    - Web Frontend Component Writing -> delegate_task(category="visual-engineering", load_skills=["frontend-ui-ux", "playwright"], ...)
+## MANDATORY: PROMETHEUS AGENT INVOCATION (NON-NEGOTIABLE)
 
-## EXECUTION RULES
-- **TODO**: Track EVERY step. Mark complete IMMEDIATELY after each.
-- **PARALLEL**: Fire independent agent calls simultaneously via delegate_task(background=true) - NEVER wait sequentially.
-- **BACKGROUND FIRST**: Use delegate_task for exploration/research agents (10+ concurrent if needed).
-- **VERIFY**: Re-read request after completion. Check ALL requirements met before reporting done.
-- **DELEGATE**: Don't do everything yourself - orchestrate specialized agents for their strengths.
-  - **CATEGORY + LOAD_SKILLS**
+**YOU MUST ALWAYS INVOKE PROMETHEUS (THE PLANNER) FOR ANY NON-TRIVIAL TASK.**
 
-## WORKFLOW
-1. Analyze the request and identify required capabilities
-2. Spawn exploration/librarian agents via delegate_task(background=true) in PARALLEL (10+ if needed)
-3. Spawn Plan agent: \`delegate_task(subagent_type="plan", prompt="<context + request>")\` to create detailed work breakdown
-4. Execute with continuous verification against original requirements

+- Prometheus analyzes dependencies and parallel execution opportunities
+- Prometheus recommends CATEGORY + SKILLS for each task (in TL;DR + per-task)
+- Prometheus ensures nothing is missed with structured work plans
+- YOU are an orchestrator, NOT an implementer

+### SESSION CONTINUITY WITH PROMETHEUS (CRITICAL)

+|-----------|--------|-----|
+| Codebase exploration | delegate_task(subagent_type="explore", run_in_background=true) | Parallel, context-efficient |
+| Documentation lookup | delegate_task(subagent_type="librarian", run_in_background=true) | Specialized knowledge |
+| Planning | delegate_task(subagent_type="plan") | Structured work breakdown |
+| Architecture/Debugging | delegate_task(subagent_type="oracle") | High-IQ reasoning |
+| Implementation | delegate_task(category="...", load_skills=[...]) | Domain-optimized models |
+
+**CATEGORY + SKILL DELEGATION:**
+\`\`\`
+// Frontend work
+delegate_task(category="visual-engineering", load_skills=["frontend-ui-ux"])
+
+// Complex logic
+delegate_task(category="ultrabrain", load_skills=["typescript-programmer"])
+
+// Quick fixes
+delegate_task(category="quick", load_skills=["git-master"])
+\`\`\`
+
+**YOU SHOULD ONLY DO IT YOURSELF WHEN:**
+- Task is trivially simple (1-2 lines, obvious change)
+- You have ALL context already loaded
+- Delegation overhead exceeds task complexity
+
+**OTHERWISE: DELEGATE. ALWAYS.**
+
+---
+
+## EXECUTION RULES (PARALLELIZATION MANDATORY)
+
+| Rule | Implementation |
+|------|----------------|
+| **PARALLEL FIRST** | Fire ALL independent agents simultaneously via delegate_task(run_in_background=true) |
+| **NEVER SEQUENTIAL** | If tasks A and B are independent, launch BOTH at once |
+| **10+ CONCURRENT** | Use 10+ background agents if needed for comprehensive exploration |
+| **COLLECT LATER** | Launch agents -> continue work -> background_output when needed |
+
+**ANTI-PATTERN (BLOCKING):**
+\`\`\`
+// WRONG: Sequential, slow
+result1 = delegate_task(..., run_in_background=false)  // waits
+result2 = delegate_task(..., run_in_background=false)  // waits again
+\`\`\`
+
+**CORRECT PATTERN:**
+\`\`\`
+// RIGHT: Parallel, fast
+delegate_task(..., run_in_background=true)  // task_id_1
+delegate_task(..., run_in_background=true)  // task_id_2
+delegate_task(..., run_in_background=true)  // task_id_3
+// Continue working, collect with background_output when needed
+\`\`\`
+
+---
+
+## WORKFLOW (MANDATORY SEQUENCE)
+
+1. **GATHER CONTEXT** (parallel background agents):
+   \`\`\`
+   delegate_task(subagent_type="explore", run_in_background=true, prompt="...")
+   delegate_task(subagent_type="librarian", run_in_background=true, prompt="...")
+   \`\`\`
+
+2. **INVOKE PROMETHEUS** (MANDATORY for non-trivial tasks):
+   \`\`\`
+   result = delegate_task(subagent_type="prometheus", prompt="<context + request>")
+   // STORE the session_id for follow-ups!
+   prometheus_session_id = result.session_id
+   \`\`\`
+
+3. **ITERATE WITH PROMETHEUS** (if clarification needed):
+   \`\`\`
+   // Use session_id to continue the conversation
+   delegate_task(session_id=prometheus_session_id, prompt="<answer to Prometheus's question>")
+   \`\`\`
+
+4. **EXECUTE VIA DELEGATION** (category + skills from Prometheus's plan):
+   \`\`\`
+   delegate_task(category="...", load_skills=[...], prompt="<task from plan>")
+   \`\`\`
+
+5. **VERIFY** against original requirements

+   - call_omo_agent(description="Research documentation", subagent_type="librarian", run_in_background=true, prompt="<search for external documentation, examples, and best practices related to user's request>")
+
+2. After gathering context, ALWAYS present:
+   - **User Request Summary**: Concise restatement of what the user is asking for
+   - **Uncertainties**: List of unclear points, ambiguities, or assumptions you're making
+   - **Clarifying Questions**: Specific questions to resolve the uncertainties
+
+3. ITERATE until ALL requirements are crystal clear:
+   - Do NOT proceed to planning until you have 100% clarity
+   - Ask the user to confirm your understanding
+   - Resolve every ambiguity before generating the work plan
+
+REMEMBER: Vague requirements lead to failed implementations. Take the time to understand thoroughly.

+
+YOU MUST INCLUDE THE FOLLOWING SECTIONS IN YOUR PLAN OUTPUT.
+THIS IS NON-NEGOTIABLE. FAILURE TO INCLUDE THESE SECTIONS = INCOMPLETE PLAN.
+
+═══════════════════════════════════════════════════════════════════
+█ SECTION 1: TASK DEPENDENCY GRAPH (MANDATORY)                    █
+═══════════════════════════════════════════════════════════════════
+
+YOU MUST ANALYZE AND DOCUMENT TASK DEPENDENCIES.
+
+For EVERY task in your plan, you MUST specify:
+- Which tasks it DEPENDS ON (blockers)
+- Which tasks DEPEND ON IT (dependents)
+- The REASON for each dependency
+
+Example format:
+\`\`\`
+## Task Dependency Graph
+
+| Task | Depends On | Reason |
+|------|------------|--------|
+| Task 1 | None | Starting point, no prerequisites |
+| Task 2 | Task 1 | Requires output/artifact from Task 1 |
+| Task 3 | Task 1 | Uses same foundation established in Task 1 |
+| Task 4 | Task 2, Task 3 | Integrates results from both tasks |
+\`\`\`
+
+WHY THIS MATTERS:
+- Executors need to know execution ORDER
+- Prevents blocked work from starting prematurely
+- Identifies critical path for project timeline
+
+
+═══════════════════════════════════════════════════════════════════
+█ SECTION 2: PARALLEL EXECUTION GRAPH (MANDATORY)                 █
+═══════════════════════════════════════════════════════════════════
+
+YOU MUST IDENTIFY WHICH TASKS CAN RUN IN PARALLEL.
+
+Analyze your dependency graph and group tasks into PARALLEL EXECUTION WAVES:
+
+Example format:
+\`\`\`
+## Parallel Execution Graph
+
+Wave 1 (Start immediately):
+├── Task 1: [description] (no dependencies)
+└── Task 5: [description] (no dependencies)
+
+Wave 2 (After Wave 1 completes):
+├── Task 2: [description] (depends: Task 1)
+├── Task 3: [description] (depends: Task 1)
+└── Task 6: [description] (depends: Task 5)
+
+Wave 3 (After Wave 2 completes):
+└── Task 4: [description] (depends: Task 2, Task 3)
+
+Critical Path: Task 1 → Task 2 → Task 4
+Estimated Parallel Speedup: 40% faster than sequential
+\`\`\`
+
+WHY THIS MATTERS:
+- MASSIVE time savings through parallelization
+- Executors can dispatch multiple agents simultaneously
+- Identifies bottlenecks in the execution plan
+
+
+═══════════════════════════════════════════════════════════════════
+█ SECTION 3: CATEGORY + SKILLS RECOMMENDATIONS (MANDATORY)        █
+═══════════════════════════════════════════════════════════════════
+
+FOR EVERY TASK, YOU MUST RECOMMEND:
+1. Which CATEGORY to use for delegation
+2. Which SKILLS to load for the delegated agent
+
+### AVAILABLE CATEGORIES
+
+| Category | Best For | Model |
+|----------|----------|-------|
+| \`visual-engineering\` | Frontend, UI/UX, design, styling, animation | google/gemini-3-pro |
+| \`ultrabrain\` | Complex architecture, deep logical reasoning | openai/gpt-5.2-codex |
+| \`artistry\` | Highly creative/artistic tasks, novel ideas | google/gemini-3-pro |
+| \`quick\` | Trivial tasks - single file, typo fixes | anthropic/claude-haiku-4-5 |
+| \`unspecified-low\` | Moderate effort, doesn't fit other categories | anthropic/claude-sonnet-4-5 |
+| \`unspecified-high\` | High effort, doesn't fit other categories | anthropic/claude-opus-4-5 |
+| \`writing\` | Documentation, prose, technical writing | google/gemini-3-flash |
+
+### AVAILABLE SKILLS (ALWAYS EVALUATE ALL)
+
+Skills inject specialized expertise into the delegated agent.
+YOU MUST evaluate EVERY skill and justify inclusions/omissions.
+
+| Skill | Domain |
+|-------|--------|
+| \`agent-browser\` | Browser automation, web testing |
+| \`frontend-ui-ux\` | Stunning UI/UX design |
+| \`git-master\` | Atomic commits, git operations |
+| \`dev-browser\` | Persistent browser state automation |
+| \`typescript-programmer\` | Production TypeScript code |
+| \`python-programmer\` | Production Python code |
+| \`svelte-programmer\` | Svelte components |
+| \`golang-tui-programmer\` | Go TUI with Charmbracelet |
+| \`python-debugger\` | Interactive Python debugging |
+| \`data-scientist\` | DuckDB/Polars data processing |
+| \`prompt-engineer\` | AI prompt optimization |
+
+### REQUIRED OUTPUT FORMAT
+
+For EACH task, include a recommendation block:
+
+\`\`\`
+### Task N: [Task Title]
+
+**Delegation Recommendation:**
+- Category: \`[category-name]\` - [reason for choice]
+- Skills: [\`skill-1\`, \`skill-2\`] - [reason each skill is needed]
+
+**Skills Evaluation:**
+- INCLUDED \`skill-name\`: [reason]
+- OMITTED \`other-skill\`: [reason domain doesn't overlap]
+\`\`\`
+
+WHY THIS MATTERS:
+- Category determines the MODEL used for execution
+- Skills inject SPECIALIZED KNOWLEDGE into the executor
+- Missing a relevant skill = suboptimal execution
+- Wrong category = wrong model = poor results
+
+
+═══════════════════════════════════════════════════════════════════
+█ RESPONSE FORMAT SPECIFICATION (MANDATORY)                       █
+═══════════════════════════════════════════════════════════════════
+
+YOUR PLAN OUTPUT MUST FOLLOW THIS EXACT STRUCTURE:
+
+\`\`\`markdown
+# [Plan Title]
+
+## Context
+[User request summary, interview findings, research results]
+
+## Task Dependency Graph
+[Dependency table - see Section 1]
+
+## Parallel Execution Graph  
+[Wave structure - see Section 2]
+
+## Tasks
+
+### Task 1: [Title]
+**Description**: [What to do]
+**Delegation Recommendation**:
+- Category: \`[category]\` - [reason]
+- Skills: [\`skill-1\`] - [reason]
+**Skills Evaluation**: [✅ included / ❌ omitted with reasons]
+**Depends On**: [Task IDs or "None"]
+**Acceptance Criteria**: [Verifiable conditions]
+
+### Task 2: [Title]
+[Same structure...]
+
+## Commit Strategy
+[How to commit changes atomically]
+
+## Success Criteria
+[Final verification steps]
