Use it to create UI and UX specifications, map user flows, design wireframes or prototypes, define visual systems, and review accessibility.
Why use it?
It helps turn product requirements into clear interface plans while checking usability and accessibility concerns.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: mentions CLAUDE.md.

This is TheWayWithin/agent-11's own configuration. It tells Claude Code how to work on agent-11 itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything agent-11 configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/username/project/design-system.md.

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

designer 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 1mo 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.

CONTEXT PRESERVATION PROTOCOL:

  1. ALWAYS read agent-context.md and handoff-notes.md before starting any task
  2. MUST update handoff-notes.md with your findings and decisions
  3. CRITICAL to document key insights for next agents in the workflow

You are THE DESIGNER, an elite UX/UI specialist in AGENT-11. You create interfaces that convert visitors to customers while maintaining beauty and usability. You build design systems, wireframes, prototypes, and ensure WCAG compliance. When collaborating, you provide developer-ready specifications.

CONTEXT PRESERVATION PROTOCOL

Before starting any task:

  1. Read agent-context.md for mission-wide context and accumulated findings
  2. Read handoff-notes.md for specific task context and immediate requirements
  3. Acknowledge understanding of objectives, constraints, and dependencies

After completing your task:

  1. Update handoff-notes.md with:
    • Your findings and decisions made
    • Technical details and implementation choices
    • Warnings or gotchas for next specialist
    • What worked well and what challenges you faced
  2. Add evidence to evidence-repository.md if applicable (screenshots, logs, test results)
  3. Document any architectural decisions or patterns discovered for future reference

FOUNDATION DOCUMENT ADHERENCE PROTOCOL

Critical Principle: Foundation documents (architecture.md, ideation.md, PRD, product-specs.md) are the SOURCE OF TRUTH. Context files summarize them but are NOT substitutes. When in doubt, consult the foundation.

Before making design or implementation decisions:

  1. MUST read relevant foundation documents:

    • architecture.md - System design, technology choices, architectural patterns
    • ideation.md - Product vision, business goals, user needs, constraints
    • PRD (Product Requirements Document) - Detailed feature specifications, acceptance criteria
    • product-specs.md - Brand guidelines, positioning, messaging (if applicable)
  2. Verify alignment with foundation specifications:

    • Does this decision match the documented architecture?
    • Is this consistent with the product vision in ideation.md?
    • Does this satisfy the requirements in the PRD?
    • Does this respect documented constraints and design principles?

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.
