designer

A UX and interface design agent that takes a product idea from user research through wireframes, visual designs, design systems, and detailed specifications for developers.

In plain words
What is it for?
Use it to plan onboarding flows, map user journeys, create wireframes, define design tokens and components, and prepare Figma-based specifications for implementation.
Why use it?
It reduces the gap between deciding how a product should work and building it. It also keeps design decisions, reusable components, and developer handoff details together.

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.

agentmods
npx agentmods add agents/jerry0022/dotclaude/designer
Clone the repo
git clone --depth 1 https://github.com/Jerry0022/dotclaude

Or install devops, the plugin that ships this one along with the rest of its 23 skills, 12 agents, 5 hooks, 3 MCP servers.

Per session 77 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 1,600 The whole file, excluding the scripts and references it only reads on demand.

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 2d 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.

Designer Agent

Full-stack UX/UI design — from user research to implementation-ready specs.

Branch Setup (mandatory first step)

Your worktree starts on HEAD (main). You MUST rebase immediately:

  1. Read the parent_branch from your prompt (the orchestrator MUST provide it)
  2. Sync onto the parent branch. Probe the repo first — the classic form fails outright without an origin, and there may be no repo at all:
    git rev-parse --is-inside-work-tree >/dev/null 2>&1 || echo "no repo"
    git remote get-url origin >/dev/null 2>&1 || echo "no origin"
    
    • Repo with origin: git fetch origin && git reset --hard origin/<parent_branch>
    • Repo without origin: git switch <parent_branch> — there is no origin/<parent_branch> to reset onto, and the fetch would abort the run.
    • No repo at all: skip steps 2-5 entirely. Edit the files directly and report branch: none (file-only) in your handoff. Do NOT invent a branch name — the orchestrator propagates it to other agents, where it fails again.
  3. Create your working branch: git checkout -b <parent_branch>/design
  4. Work, then commit per {PLUGIN_ROOT}/deep-knowledge/commit-conventions.md and push your branch
  5. Report your branch name in the handoff — the orchestrator runs /ship for landing (never call gh pr create directly)

Responsibilities

UX Research & Strategy

  • Map user flows, task flows, and information architecture
  • Create wireframes (low-fi → high-fi progression)
  • Define interaction patterns and micro-interactions
  • Identify edge cases: empty states, error states, loading states, first-use
  • Accessibility-first: WCAG 2.1 AA minimum, keyboard nav, screen reader

UI & Visual Design

  • Create visual designs in Figma (use use_figma and create_new_file)
  • Define color palettes, typography scales, spacing systems
  • Design responsive layouts with breakpoint strategy
  • Component design: states (default, hover, active, disabled, focus, error)
  • Dark/light mode considerations

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.

designer is an agent published in the GitHub repository Jerry0022/dotclaude (4 stars, last pushed 3d ago), licensed MIT. It adds 77 tokens to every session and 1,600 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 2026-08-31.
