mobile

mobile is a command for Claude Code from textura-agency/next16-claude-starter. It costs 31 tokens per session (547 once invoked), scanned A, original, Unlicense.

A command for checking and fixing website behavior on real phones, using a mobile quality checklist and browser probes for known problem areas.

In plain words
What is it for?
It helps check iOS resizing, WebGL context loss, animation speed, mobile menus, safe areas, overflow, sliders, cursors, scrolling, and light or dark color schemes.
Why use it?
A site can pass desktop and automated checks while failing on an iPhone because of its browser toolbar, touch input, screen speed, memory, or motion features. The command tests a reported symptom or runs a broader sweep, then repeats the same check after the fix.

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 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 11d 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

Harden for real phones: $ARGUMENTS (the whole site if empty — or the symptom a reviewer reported, quoted).

Use the mobile-device-qa skill. Every item there passed Lighthouse and the headless scroll test and was then found by a person on an iPhone, so:

  1. yarn build && yarn start; yarn qa:setup once. Probes use a person's UA (the default headless UA gets the robot form) — and look at every screenshot.
  2. A reported symptom: find its section in the skill (symptom → cause → fix → proof), reproduce it first with the named tool — if it is iOS-only and Chrome can't reproduce it, node tools/qa/webkit-probe.mjs --url ….
  3. A full sweep: ios-toolbar-probe.mjs and context-loss-probe.mjs for any live scene; fps-probe.mjs (no fixed phone caps; motion dt-scaled for 120 Hz); the mobile menu at 390×844 closed / mid-open / open / closing in light and dark scheme (dvh + safe area, portal under <body>, focus in and back); overflow at 320–430; split headlines; touch sliders; custom cursors off on touch; the first scroll after the loader; resize-check.mjs.
  4. Fix one thing, prove it with the same probe (FAIL → PASS), then node tools/qa/scroll-test.mjs --url … and node tools/qa/lighthouse.mjs --url … — no regression in phone scroll, A11y/BP/SEO stay 100.
  5. .claude/scripts/verify.sh, yarn lint, npx tsc --noEmit -p ., yarn build.

Gyroscope hero motion is opt-in — ask before adding it. Never remove a 3D scene on mobile without the client's sign-off.

Report per item: cause, fix, the proof (tool + result), and what could only be checked in emulation — then ask the client (or a teammate) to open a preview on their phone, naming exactly what to try. New iOS lessons → obsidian/knowledge/pitfalls.md.

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.
