## ⚠️ EXECUTION CONTRACT (MANDATORY - CANNOT SKIP)

This skill uses **ENFORCED execution mode**. You MUST follow this exact sequence.

### STEP 1: Display Visual Indicators (MANDATORY - BLOCKING)

**Check provider availability:**

```bash
command -v codex &> /dev/null && codex_status="Available ✓" || codex_status="Not installed ✗"
command -v gemini &> /dev/null && gemini_status="Available ✓" || gemini_status="Not installed ✗"
```

**Display this banner BEFORE orchestrate.sh execution:**

```
🐙 **CLAUDE OCTOPUS ACTIVATED** - Architecture design mode
🏗️ Architecture: [Brief description of system to design]

Provider Availability:
🔴 Codex CLI: ${codex_status} - Backend architecture patterns
🟡 Gemini CLI: ${gemini_status} - Alternative approaches
🔵 Claude: Available ✓ - Synthesis and recommendations

💰 Estimated Cost: $0.02-0.08
⏱️  Estimated Time: 3-7 minutes
```

**Validation:**
- If BOTH Codex and Gemini unavailable → STOP, suggest: `/octo:setup`
- If ONE unavailable → Continue with available provider(s)
- If BOTH available → Proceed normally

**DO NOT PROCEED TO STEP 2 until banner displayed.**

---

### STEP 2: Execute orchestrate.sh spawn (MANDATORY - Use Bash Tool)

**You MUST execute this command via the Bash tool:**

```bash
${HOME}/.claude-octopus/plugin/scripts/orchestrate.sh spawn backend-architect "<user's architecture request>"
```

**CRITICAL: You are PROHIBITED from:**
- ❌ Designing architecture directly without calling orchestrate.sh
- ❌ Using direct analysis as a substitute
- ❌ Claiming you're "simulating" the workflow
- ❌ Proceeding to Step 3 without running this command

**This is NOT optional. You MUST use the Bash tool to invoke orchestrate.sh.**

---

### STEP 3: Verify Execution (MANDATORY - Validation Gate)

**After orchestrate.sh completes, verify it succeeded:**

```bash
# Check for persona output (varies by persona type)
# For spawn commands, check exit code and output
if [ $? -ne 0 ]; then
  echo "❌ VALIDATION FAILED: orchestrate.sh spawn failed"
  exit 1
fi

echo "✅ VALIDATION PASSED: Architecture design completed"
```

**If validation fails:**
1. Report error to user
2. Show logs from `~/.claude-octopus/logs/`
3. DO NOT proceed with presenting results
4. DO NOT substitute with direct design

---

### STEP 4: Present Results (Only After Steps 1-3 Complete)

Present the architecture design from the persona execution.

**Include attribution:**

# Architecture Skill

Invokes the backend-architect persona for system design during the `grasp` (define) and `tangle` (develop) phases.

## Usage

```bash
# Via orchestrate.sh
${HOME}/.claude-octopus/plugin/scripts/orchestrate.sh spawn backend-architect "Design a scalable notification system"

# Via auto-routing (detects architecture intent)
${HOME}/.claude-octopus/plugin/scripts/orchestrate.sh auto "architect the event-driven messaging system"
```

## Capabilities

- API design and RESTful patterns
- Microservices architecture
- Distributed systems design
- Event-driven architecture
- Database schema design
- Scalability planning

## Persona Reference

This skill wraps the `backend-architect` persona defined in:
- `agents/personas/backend-architect.md`
- CLI: `codex`
