CTX:Architect - Structured Design Workflow
Senior architect workflow: Understand → Research → Specify → Decompose → Plan
Core Workflow
1. Understand the Problem
Extract essentials:
- Core problem (what's the real need?)
- Constraints (time, budget, skills, existing systems)
- Success criteria (what does "done" look like?)
- Assumptions (make implicit explicit)
If unclear, ask:
- "What problem does this solve?"
- "What systems must it integrate with?"
- "Expected scale/volume?"
- "Must-haves vs. nice-to-haves?"
2. Research Existing Solutions
Use WebSearch to find:
- Existing tools/libraries:
"best [tech] for [problem] 2025" - Implementation patterns:
"[problem] implementation examples" - Known challenges:
"[problem] pitfalls" - Comparisons:
"[tool A] vs [tool B]"
Evaluate each solution:
- Maturity (active? community?)
- Fit (solves 80%+?)
- Integration (works with stack?)
- Cost (license, hosting)
- Risk (lock-in, learning curve)
Output: Comparison table with pros/cons
3. Develop Specifications
Structure:
## Problem Statement
[1-2 sentences]
## Requirements
- [ ] Functional (High/Med/Low priority)
- [ ] Performance (metrics, scale)
- [ ] Security (requirements)
## Constraints
- Technical: [stack, systems]
- Resources: [time, budget, team]
## Success Criteria
- [Measurable outcomes]
If specs missing, ask:
- Functional: "What must it do?" "Inputs/outputs?" "Edge cases?"
- Non-functional: "How many users?" "Response time?" "Uptime?"
- Technical: "Current stack?" "Team skills?" "Deployment constraints?"
4. Decompose into Tasks
Process:
- Identify major components
- Break into 1-3 day tasks
- Classify: Independent | Sequential | Parallel-ready
- Map dependencies
Dependency mapping:
Task A (indep) ────┐
Task B (indep) ────┼──> Task D (needs A,B,C)
Task C (indep) ────┘
Task E (needs D) ──> Task F (needs E)
For each task:
- Prerequisites (what must exist first?)
- Outputs (what does it produce?)
- Downstream (what depends on it?)
- Parallelizable? (can run with others?)
5. Create Execution Plan
Phase structure:
## Phase 1: Foundation (Parallel)
- [ ] Task A - Infrastructure
- [ ] Task B - Data models
- [ ] Task C - CI/CD
## Phase 2: Core (Sequential after Phase 1)
- [ ] Task D - Auth (needs A,B)
- [ ] Task E - API (needs B)
## Phase 3: Features (Mixed)
- [ ] Task F - Feature 1 (needs D,E)
- [ ] Task G - Feature 2 (needs D,E) ← Parallel with F
Per task include:
- Description (what to build)
- Dependencies (prerequisites)
- Effort (S/M/L)
- Owner (who can execute)
- Done criteria (how to verify)
- Risks (what could fail)
Build vs. Buy Decision
| Factor | Build | Buy |
|---|---|---|
| Uniqueness | Core differentiator | Common problem |
| Fit | Tools don't match | 80%+ match |
| Control | Need full control | Standard OK |
| Timeline | Have time | Need speed |
| Expertise | Team has skills | Steep curve |
| Maintenance | Can maintain | Want support |
Hybrid: Buy infrastructure/common features, build differentiation
Critical Success Factors
✅ Research first (don't reinvent) ✅ Make dependencies explicit (enable parallel work) ✅ Ask direct questions (get clarity fast) ✅ Document trade-offs (explain decisions) ✅ Think in phases (iterative delivery) ✅ Consider team (match to capabilities)
Activation Triggers
- "Design a system for..."
- "How should I architect..."
- "Break down this project..."
- "What's the best approach..."
- "Help me plan..."
- "Should I build or buy..."
Integration with Contextune
This skill is invoked automatically when Contextune detects /ctx:design command.
Workflow:
- User types: "design a caching system"
- Contextune detects:
/ctx:design - Hook augments: "You can use your ctx:architect skill..."
- Claude should ask: "I detected this is a design task. Would you like me to use the ctx:architect skill (structured workflow) or proceed directly?"
- User chooses, workflow proceeds
Output: Structured specifications, researched alternatives, executable plan with dependencies
