lenserfight: Skill for Codex

.agents/skills/mobile-app-designer/SKILL.md

mobile-app-designer is a skill for Codex from conectlens/lenserfight. It costs 44 tokens per session (361 once invoked), scanned A, original, MIT.

A design guide for Expo Go React Native screens in the mobile app, covering iOS and Android differences, shared components, themes, spacing, typography, and interactions. Expo Go is a tool for running React Native apps during development.

In plain words
What is it for?
Use it when designing or refining screens in apps/mobile, choosing native interactions, applying the existing theme, or deciding whether to reuse shared mobile components.
Why use it?
It helps new screens look and behave like the existing product on both major mobile platforms. It also reduces one-off UI decisions and keeps the app's shared design system consistent.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is conectlens/lenserfight's own configuration. It tells Codex how to work on lenserfight 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 lenserfight configures →

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-app-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 9d 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

Mobile App Designer

Load ../mobile-ruleset/references/RULESET.md first, then follow references/DESIGN_GUIDELINES.md.

Design for apps/mobile only. Treat iOS and Android as related but distinct platforms, and evaluate both before deciding on interaction, spacing, navigation, or component choices.

Focus on:

  • sector-standard mobile patterns for iOS and Android separately
  • the app's default palette and theme tokens
  • shared secure, sector-standard native primitives from libs/ui/components
  • theme and token wiring from libs/ui/theme and libs/ui/tokens
  • the real mobile product tree, especially Chao Chat, Chao features, project management, notifications, CRON jobs, and settings
  • consistent spacing, typography, and surface hierarchy
  • simple, predictable interactions over novelty

Rules:

  • keep all mobile screens feeling like one product
  • prefer shared primitives and mature native libraries over custom one-off components when they improve security or performance
  • use the existing palette before introducing new colors
  • preserve the app-specific feature tree; do not mirror forum pages into mobile one-for-one
  • avoid decorative complexity unless it improves clarity
  • keep mobile work centered on mobile-first flows, not desktop parity

After design work, verify with the smallest useful mobile test set. Prefer pnpm nx run mobile:test, pnpm nx run mobile:build, and pnpm nx run ui:lint when shared UI is touched.

What ships with it

2 files 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.
