⚠️ EXECUTION CONTRACT (MANDATORY - CANNOT SKIP)

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

STEP 1: Display Visual Indicators (MANDATORY - BLOCKING)

MANDATORY: Run the centralized provider check BEFORE displaying the banner:

bash "${HOME}/.claude-octopus/plugin/scripts/helpers/check-providers.sh"

Use the ACTUAL results. PROHIBITED: Showing only "🔵 Claude: Available ✓" without listing all providers.

Display this banner BEFORE orchestrate.sh execution (list ALL providers from check output):

🐙 **CLAUDE OCTOPUS ACTIVATED** - Architecture design mode
🏗️ Architecture: [Brief description of system to design]
 
Provider Availability:
🔴 Codex CLI: [status from check] - Backend architecture patterns
🟡 Gemini CLI: [status from check] - Alternative approaches
🟢 Copilot CLI: [status from check] - GitHub integration
🟣 Qwen CLI: [status from check] - Additional perspective
🟤 OpenCode CLI: [status from check] - Multi-provider routing
🔵 Claude: Available ✓ - Synthesis and recommendations
 
💰 Estimated Cost: $0.02-0.08
⏱️  Estimated Time: 3-7 minutes

Validation:

• If ALL external CLI providers unavailable → STOP, suggest: /octo:setup
• If some unavailable → Continue with available provider(s)
• If multiple 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:

${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:

# 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.

Architecture Skill

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

Usage

# 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
• Model: gpt-5.3-codex
• Phases: grasp, tangle
• Expertise: api-design, microservices, distributed-systems

Example Prompts

"Design the API contract for the user service"
"Plan the event sourcing architecture"
"Design the caching strategy for the product catalog"
"Create a microservices decomposition plan"

LSP Integration (Claude Code 2.1.14+)

For enhanced structural awareness during architecture design, leverage Claude Code's LSP tools:

Recommended LSP Tool Usage

1. Before defining architecture, gather structural context:

`` lsp_document_symbols - Understand existing module structure lsp_find_references - Identify current dependencies lsp_workspace_symbols - Find related patterns across codebase ``

1. During design validation:

`` lsp_goto_definition - Verify interface contracts lsp_hover - Check type signatures lsp_diagnostics - Identify type/interface mismatches ``

Example Workflow

// Step 1: Understand existing structure
const symbols = await lsp_document_symbols("src/services/user.ts")
const references = await lsp_find_references("UserService", line=5, char=10)
// Step 2: Identify patterns in codebase
const patterns = await lsp_workspace_symbols("Service")
// Step 3: Design new architecture informed by existing patterns
// ... architecture design ...
// Step 4: Validate design with diagnostics
const issues = await lsp_diagnostics("src/services/*.ts")

This ensures architecture recommendations align with existing codebase patterns and type contracts.
