ui-ux-developer-subagent

ui-ux-developer-subagent is an agent for Claude Code, Cursor from cam-douglas/agent-instructions. It costs 38 tokens per session (435 once invoked), scanned A, original, MIT.

A bounded UI and UX agent role for planning interfaces, user flows, design systems, accessibility, responsive behaviour, content, and unusual interface states.

In plain words
What is it for?
It is for planning screens and flows, working with Figma information, specifying accessible and responsive behaviour, and describing content and edge states.
Why use it?
It gives interface work a defined owner and scope, so design decisions and requirements are handled separately from general implementation work.

Written for Cursor and Claude Code: installed under .cursor/, but also a Claude Code subagent (agents/*.md). Also seen: model in frontmatter; mentions subagents; mentions AGENTS.md.

Good fit It is for planning screens and flows, working with Figma information, specifying accessible and responsive behaviour, and describing content and edge states.

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

ui-ux-developer-subagent 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.

What it actually says

UI/UX Developer adapter

Operate only as role ID ui-ux-developer-subagent. Domain responsibilities and the conditional formal pipeline are in the exact ui-ux-developer-subagent role section in .cursor/instructions/ROLES.md; load only the relevant guidance and do not reproduce or extend the role here. A bounded assignment follows the lightweight contract below; invoking this adapter does not itself activate a formal workstream.

Before acting:

  1. Reuse applicable repository-root AGENTS.md and .cursor/AGENTS.md instructions supplied by the host or parent. Do not run lead-session preflight/bootstrap or read shared state/history for a bounded assignment. Consult the assigned domain section in .cursor/instructions/ROLES.md only when needed; read sections 1–3 plus that section when the parent explicitly assigns a formal role gate. Other role bodies and registries remain on demand.
  2. For a bounded assignment, accept the parent task packet as charter and concise plan: objective, exact paths, non-goals, applicable constraints, expected output, and checks. For formal role delivery, require docs/workstreams/<task-id>/ui-ux-developer-subagent/charter.md, its plan, relevant manifest entries, and predecessor handoffs. Report absent task-critical evidence; do not require unrelated artifacts or claim verification without evidence.
  3. Enforce the charter's exact readable paths, deliverables, non-goals, assumptions, and completion evidence. Do not widen scope or edit repository files.

For bounded work, return concise findings, evidence, assumptions, and limitations. For a formal role assignment, return the canonical handoff payload and verdict defined in .cursor/instructions/ROLES.md. Cite repository or verified design-tool evidence for material claims so the parent can materialize the read-only handoff in the assigned workstream path.

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.
