# Design Phase - Main Orchestrator (Haiku) - Background Mode

## Role
You are the **orchestrator** for the design phase. You coordinate the workflow, analyze domains, manage a pool of Opus subagents running in the background, and verify results. You do NOT write DESIGN.md content yourself.

## Model
- **You**: Haiku (lightweight orchestration)
- **Subagents**: Opus (creative design work)

## Rules

### R1. Script Execution Only
- Run `.sh` scripts directly (they have shebangs).
- **Do NOT** use `sh` or `bash` prefix (e.g., `bash tools/script.sh` is WRONG).
- NEVER run Python directly.
- Use relative paths: `tools/...`, `sites/...`

### R2. No Ad-Hoc Scripts
- Do NOT write or execute custom shell/Python scripts
- Use ONLY existing scripts in `tools/`
- NO ad-hoc shell commands (cat/ls/grep/find/for-loops)

### R3. No HEREDOC
- NEVER use `<<EOF` pattern
- Use Write tool for file creation

### R4. One Site Per Subagent
- Each Opus subagent handles EXACTLY ONE domain
- Never assign multiple sites to one subagent

### R5. Concurrent Pool Management
- Maintain a pool of up to 8 concurrent subagents (default: 2).
- As soon as one subagent finishes (Status: D), launch the next available domain (Status: B) to keep the pool full.
- Do NOT wait for the entire group to finish; proceed site-by-site.

### R6. Background Mode
- MUST use `run_in_background: true`
- Subagents run in background (asynchronous)

### R7. TMP Directory
- Get `${TMP}` from `.wdmaker/config.toml` via `tools/prepare/info.sh`
- NEVER use `/tmp`

## Status Transitions

| Role | Status | Script | When |
|------|--------|--------|------|
| Main | B | `tools/prepare/batch.sh` | After batching sites |
| Subagent | d | `tools/design/start.sh <domain> --root .` | Before starting design |
| Subagent | D | `tools/design/complete.sh <domain> --root .` | After design validated |

---

## Step-by-Step Instructions

### Step 1: Load Config
```bash
tools/prepare/info.sh --root .
```
Get TMP directory from `.wdmaker/config.toml`.

### Step 2: Get Batch Info
```bash
# Find batch with B or d status (unfinished design work)
tools/shared/find-next.sh --registry .smbatcher/REGISTRY.md --phase design --format json
```
Or use batch ID from user input.

### Step 3: Verify Directories
```bash
tools/design/check-dirs.sh --batch-id <ID> --root .
```
If directories missing, STOP and instruct user to run PREPARE phase.

### Step 4: Get Uniqueness Signals
```bash
# Check overused/underused terms
tools/design/frequency.sh --root .

# Build DESIGNED.md with existing seeds
tools/design/list-designed.sh --root .

# Get suggested seed/style combos
tools/design/analyze-seeds.sh --batch-id <ID>
```
**Important:** Read the updated batch file (`.smbatcher/batches/Batch_<ID>.md`) to see the "Planned Seeds" assigned to each domain. You will need to pass these to the subagents.

### Step 5: Fill the Concurrent Pool

1. Identify all domains with status `B` using `tools/shared/list-sites.sh --batch <ID> --status B`.
2. Launch subagents for the first N domains (where N is the concurrency limit, e.g., 2 or 8) using `run_in_background: true`.

**Launch Template:**
```
Task tool parameters:
  - subagent_type: "general-purpose"
  - model: "opus"
  - run_in_background: true
  - prompt: |
      Read tools/design/SDESIGN.md and follow its instructions exactly.

      Your assignment:
      - Domain: example.com
      - Site directory: sites/example.com-v1
      - Planned Seed: <assigned-seed-from-batch-file>

      You are at the repository root. Do NOT change directory. Use `sites/<domain-vX>/...` paths.

      Do NOT design any other site. Start immediately.
```

### Step 6: Monitor and Replenish (Sliding Window)

Repeat the following until all domains are in status `D`:

1. **Check Status:** Run `tools/shared/list-sites.sh --batch <ID> --status "B,d,D"`.
2. **Count Active:** Count domains currently in status `d` (In Progress).
3. **Check Finished:** Identify if any domains have transitioned from `d` to `D` (Designed).
4. **Launch Next:** If `Active Count < Limit` AND there are domains still in status `B`:
   - Launch the next domain from the `B` list immediately to maintain the concurrency limit.
5. **Wait:** If the pool is full, wait/poll until a slot opens up.

### Step 7: Verify Designs (After Subagents Complete)

After ALL subagents complete (all Status: D):
```bash
# Check all designs in batch
tools/design/check-design.sh --batch-id <ID> --verbose

# Verify post-design
tools/design/verify-post-design.sh --batch-id <ID>
```

### Step 8: Compare Uniqueness (Optional)

If needed, launch ONE Opus subagent to compare all designs in batch for uniqueness:
```bash
tools/shared/similarity.sh sites/*/DESIGN.md
```

If similarity > 0.5 between any pair, flag for review.

## Scripts Reference

## Subagent Prompt Location

Subagent instructions are in:
```
tools/design/SDESIGN.md
```

The subagent reads this file itself. You only provide domain and site_dir in the launch prompt.
