mobile-uiux

mobile-uiux is a skill for Claude Code, Codex from pillip/claude-dev-kit. It costs 47 tokens per session (11,487 once invoked), scanned A, original, MIT.

A mobile product-design workflow that turns project requirements into a mobile design system, wireframes, and a React Native prototype built with Expo.

In plain words
What is it for?
Use it after the project kickoff to plan screen structure and user flows, create wireframes, and produce an initial Expo-based mobile prototype.
Why use it?
It gives developers a defined mobile interface to build from instead of starting with screens and styling decisions from scratch.

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

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

mobile-uiux 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 4d 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.

The opening of the file, as written. The whole thing — 591 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Kit Preamble — mobile-uiux

Kit Script Root

Kit root: ${CLAUDE_PLUGIN_ROOT}

  • Absolute path above → plugin install (substituted at load time; no project scripts/ dir): prefix every kit script command with it, e.g. bash <kit-root>/scripts/checkpoint.sh …. Absolute paths also work from worktrees.
  • Literal ${…} placeholder above → standalone layout: run commands as written.

Project Context Detection

Run these checks silently at the start. Use results to adapt behavior:

  • [ -f issues.md ] — if true, this project uses the sprint system. Respect issue numbering and STATUS.md.
  • [ -f docs/sprint_state.md ] — if true and Status shows running, a sprint is active. Be aware of parallel work in worktrees.
  • [ -f docs/prd_digest.md ] — if true, read it for quick project context before starting.

Kit Rules

  • Verify gh auth status before any GitHub operation.

Prerequisites

  • /kickoff must be run first so that the following files exist:
    • docs/ux_spec.md (core input — IA, flows, screen inventory)
    • docs/requirements.md (functional/non-functional requirements)
    • docs/architecture.md (tech stack reference)
  • The PRD file is supplementary reference. If kickoff outputs are missing, guide the user to run /kickoff.

Algorithm

Phase 1 — Context Gathering

  1. Read kickoff outputs (required):
    • docs/ux_spec.md — extract screen inventory, IA, flows
    • docs/requirements.md — identify UI elements from functional requirements
    • docs/architecture.md — confirm tech stack, API endpoints
  2. Read PRD ($ARGUMENTS or PRD.md) as supplementary context. If docs/prd_digest.md exists, read it for quick PRD summary.
  3. If docs/ux_spec.md does not exist:
    • Stop and tell the user: "Kickoff outputs are missing. Please run /kickoff PRD.md first."
    • Exception: if the user explicitly wants to skip kickoff, proceed with PRD only (warn about limited context).
  4. Check for existing shared assets:
    • docs/design_philosophy.md — check if already generated by web /uiux
    • docs/copy_guide.md — check if already generated by web /uiux
  5. Scan the project for existing mobile code, then choose the working mode:
    • Glob for **/*.tsx, **/*.ts, app.json, app.config.js, app.config.ts
    • If found, read key files to understand current design patterns and tech stack.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
