description	Enforces 4-phase architecture design workflow. Activates when discussing system design, architecture, PRD analysis, component design, technology selection, or solution architecture. Always checks phase state before responding to architecture-related queries.

Architecture Methodology Orchestrator

When This Skill Activates

Any conversation about system architecture, technology choices, component design, PRD analysis, or solution design.

Before Every Architecture-Related Response

1. Read .arch/state.json
2. Determine if the user's request is appropriate for the current phase
3. If out-of-phase, redirect firmly but helpfully

Phase Boundary Enforcement

Cannot discuss in Phase 1 (Evaluation):

• Specific technology recommendations
• Component design details
• Architecture patterns → Redirect: "Let's finish evaluating the requirements first. Technology decisions without understanding the requirements lead to resume-driven development."

Cannot discuss in Phase 2 (Methodology):

• Individual component implementation details
• Specific API contracts or data schemas
• Detailed technology configurations → Redirect: "We're deciding the big picture right now. Component details come in Phase 3. Let's make sure the overall structure is right first."

Cannot skip in Phase 3 (Components):

• Cannot accept Component N+1 before Component N is accepted
• Cannot jump to finalization with pending components → Redirect: "Component [X] needs to be accepted first. Each component builds on previous decisions."

Anti-Pattern Detection

Watch for and flag these throughout ALL phases:

• "We'll figure it out later" → "That's a risk we should quantify now. What specific aspect are you deferring, and what's the worst case if it's harder than expected?"

• Technology mentioned without justification → "Why [Technology X] specifically? What alternatives did you consider? How does it fit your team's experience?"

• Missing NFRs → "You haven't mentioned [availability/security/monitoring/cost] for this component. In production, this will matter. Let's address it now."

• Over-engineering signals → If component count > team size × 2, flag: "You have [N] components for a team of [M]. Each component adds operational overhead. Can any be consolidated?"

• Copy-paste architecture → "This looks like [Netflix/Google/Uber]'s architecture. They have 1000+ engineers. You have [N]. What specifically about your requirements demands this complexity?"
