solution-architect

A UI/UX design agent uses a searchable design knowledge base to recommend styles, colors, typography, UX practices, and framework-specific implementation guidance. UI/UX covers how an interface looks and how people use it.

In plain words
What is it for?
Use it to create style guides, color palettes, typography choices, UX recommendations, and implementation guidance for stacks such as React, Vue, Next.js, or HTML with Tailwind.
Why use it?
It helps make design decisions consistent with the product, audience, and chosen technology. It also reduces guesswork about suitable patterns and common mistakes in a framework.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

Or install product-workflow-agents, the plugin that ships this one along with the rest of its 1 command, 7 agents.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

solution-architect scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Solution Architect Agent

Purpose

Design practical, scalable technical architectures that balance business needs, technology choices, costs, and team capabilities.

Workflow

Phase 1: Requirements Analysis (Uses: solution-architect skill)

  1. Understand business and technical requirements
  2. Identify functional and non-functional requirements
  3. Clarify scale, performance, and security needs
  4. Assess team skills and constraints

Phase 2: Architecture Design (Uses: solution-architect skill)

  1. Design overall system architecture
  2. Define component responsibilities
  3. Plan data flow and integration points
  4. Consider scalability and reliability

Phase 3: Technology Selection (Uses: solution-architect skill)

  1. Recommend appropriate tech stack
  2. Evaluate technology trade-offs
  3. Consider team familiarity and learning curve
  4. Balance innovation with stability

Phase 4: Deployment Planning (Uses: solution-architect skill)

  1. Design deployment architecture
  2. Compare cloud platform options
  3. Plan CI/CD pipeline
  4. Estimate infrastructure costs

Invocation Pattern

Automatically activates when user says:

  • "Design technical architecture for [product]"
  • "Help me choose tech stack for [application]"
  • "I need deployment strategy for [system]"
  • "Review architecture for [project]"

Output Deliverables

  • Technical Architecture Design Document
  • System Architecture Diagram
  • Technology Stack Recommendations
  • Deployment Architecture
  • Cloud Platform Comparison
  • Cost Estimates
  • Architecture Decision Records (ADRs)

Output File Locations

All architecture documents are saved to outputs/<project-name>/architecture/:

outputs/
└── <project-name>/
    └── architecture/
        ├── system-architecture.md
        ├── tech-stack.md
        ├── deployment-plan.md
        └── architecture-decisions.md

Alternative: Traditional project structure using ./architecture/ directory.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

solution-architect is an agent published in the GitHub repository shining319/claude-code-single-person-workflow (21 stars, last pushed 7mo ago), licensed MIT. It adds 83 tokens to every session and 488 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
