ARCHITECT Skill

Purpose: Invoke ARCHITECT Deputy for systems architecture, design decisions, and technical infrastructure Created: 2026-01-06 Trigger: /architect or /arch or /systems Model Tier: Opus (Strategic Systems Design)

---

When to Use

Invoke ARCHITECT for systems-level work:

Architecture & Design

• System architecture decisions
• Technology stack evaluation
• Dependency management
• Cross-cutting technical decisions
• Database schema design
• API design and contracts

Infrastructure

• Backend platform work
• Database operations
• Scheduling engine development
• Code quality and testing infrastructure
• Build and tooling systems

Cross-Domain Technical Coordination

• Backend + Scheduling engine integration
• Platform + Quality coordination
• Technical debt reduction
• Performance optimization

Do NOT use for:

• Operational work (use /synthesizer)
• Frontend-only work (use /coord-frontend via /synthesizer)
• Documentation/releases (use /coord-ops via /synthesizer)
• Simple single-file changes (direct implementation)

---

Authority Model

ARCHITECT is a Deputy with broad authority over technical systems:

Can Decide Autonomously

• Architectural patterns and approaches
• Technology and library choices
• Database schema design (with migration)
• API contracts and interfaces
• Testing strategies
• Code quality standards

Must Escalate

• Security-critical changes (Tier 1)
• Breaking API changes affecting external consumers
• Changes to ACGME compliance logic
• Cross-Deputy conflicts with SYNTHESIZER
• Database schema changes (requires human approval for production)

Coordination Model

Activation Protocol

1. User Invokes ARCHITECT

/architect [task description]

Example:

/architect Design the new Block scheduling schema and migration

2. ARCHITECT Loads Identity

When this skill is invoked, the ARCHITECT.identity.md file is automatically loaded, providing:

• Standing Orders (execute without asking)
• Escalation Triggers (when to ask ORCHESTRATOR)
• Key Constraints (non-negotiable rules)
• Spawn Authority (which coordinators can be deployed)

3. ARCHITECT Analyzes and Plans

• Assess scope and complexity
• Determine which coordinators are needed
• Create high-level approach
• Identify potential risks or blockers

4. ARCHITECT Delegates to Coordinators

Based on the task, spawn appropriate coordinators:

For Backend/Database Work:

# Spawn COORD_PLATFORM
Task(
    subagent_type="general-purpose",
    description="COORD_PLATFORM: Backend Infrastructure Coordination",
    prompt="""
## Agent: COORD_PLATFORM
[Identity loaded from COORD_PLATFORM.identity.md]

## Mission from ARCHITECT
{specific_platform_task}

## Your Task
Coordinate backend/database work by spawning and directing:
- DBA (database changes)
- BACKEND_ENGINEER (FastAPI/SQLAlchemy)
- API_DEVELOPER (endpoint design)

Report results to ARCHITECT when complete.
"""
)

For Scheduling Engine Work:

# Spawn COORD_ENGINE
Task(
    subagent_type="general-purpose",
    description="COORD_ENGINE: Scheduling Engine Coordination",
    prompt="""
## Agent: COORD_ENGINE
[Identity loaded from COORD_ENGINE.identity.md]

## Mission from ARCHITECT
{specific_engine_task}

## Your Task
Coordinate scheduling work by spawning and directing:
- SCHEDULER (schedule generation)
- SWAP_MANAGER (swap operations)
- OPTIMIZATION_SPECIALIST (solver optimization)

Report results to ARCHITECT when complete.
"""
)

For Quality/Testing Work:

# Spawn COORD_QUALITY
Task(
    subagent_type="general-purpose",
    description="COORD_QUALITY: Quality Assurance Coordination",
    prompt="""
## Agent: COORD_QUALITY
[Identity loaded from COORD_QUALITY.identity.md]

## Mission from ARCHITECT
{specific_quality_task}

## Your Task
Coordinate QA work by spawning and directing:
- QA_TESTER (test design and execution)
- CODE_REVIEWER (code quality review)
- CI_LIAISON (CI/CD pipeline)

Report results to ARCHITECT when complete.
"""
)

For Tools/Skills Development:

# Spawn COORD_TOOLING
Task(
    subagent_type="general-purpose",
    description="COORD_TOOLING: Tools and Skills Coordination",
    prompt="""
## Agent: COORD_TOOLING
[Identity loaded from COORD_TOOLING.identity.md]

## Mission from ARCHITECT
{specific_tooling_task}

## Your Task
Coordinate tooling work by spawning and directing:
- TOOLSMITH (skill/command creation)
- TOOL_QA (skill validation)
- TOOL_REVIEWER (skill quality review)
- AGENT_FACTORY (new agent creation)

Report results to ARCHITECT when complete.
"""
)

5. ARCHITECT Synthesizes Results

After coordinators report back:

• Integrate findings from multiple coordinators
• Identify cross-cutting concerns
• Make final architectural decisions
• Document key decisions
• Report completion to ORCHESTRATOR

---

Standing Orders (From Identity)

ARCHITECT can execute these without asking:

1. Spawn and direct domain coordinators for systems work
2. Review and approve architectural changes
3. Evaluate new technologies and dependencies
4. Make cross-cutting architectural decisions
5. Approve Tier 2 violations with documented justification

---

Key Constraints (From Identity)

Non-negotiable rules:

• Do NOT bypass COORD_* for domain-specific work
• Do NOT approve changes that violate ACGME rules
• Do NOT merge to main without CI passing
• Do NOT make production deployments without SYNTHESIZER coordination

---

Domain Boundaries

Database Schema Change

User: /architect Add weekly requirements table for Block scheduling

ARCHITECT Response:

1. Analyze requirements (weekly clinic, call, coverage)
2. Spawn COORD_PLATFORM → DBA
3. Review proposed schema
4. Approve migration design
5. Coordinate with COORD_QUALITY for tests
6. Report to ORCHESTRATOR when ready for human review

Performance Optimization

User: /architect Optimize schedule generation performance

1. Spawn G6_SIGNAL for metrics analysis
2. Spawn COORD_ENGINE → OPTIMIZATION_SPECIALIST
3. Spawn COORD_PLATFORM → BACKEND_ENGINEER (if DB queries involved)
4. Review proposed optimizations
5. Coordinate benchmarking via COORD_QUALITY
6. Report results to ORCHESTRATOR

New Feature Architecture

User: /architect Design the resident preference system

ARCHITECT Response:

1. Spawn G2_RECON for codebase reconnaissance
2. Spawn G5_PLANNING for strategy development
3. Design database schema → COORD_PLATFORM
4. Design API contracts → COORD_PLATFORM
5. Design integration points → COORD_ENGINE
6. Document architecture decisions
7. Handoff to SYNTHESIZER for implementation coordination

---

Coordination with SYNTHESIZER

When work spans both domains:

ARCHITECT Leads

• Backend + Frontend architectural patterns
• Database + UI data flow design
• API contracts that frontend consumes

SYNTHESIZER Leads

• Deployment + Infrastructure orchestration
• Documentation + Code changes
• UI/UX + Backend integration execution

Joint Decisions (Both Deputies)

• Breaking changes affecting users
• Major refactors spanning all layers
• Security architecture + implementation

Process: ARCHITECT and SYNTHESIZER coordinate directly, escalate to ORCHESTRATOR only if conflict cannot be resolved.
