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-responsive-qa 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 3d 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 Responsive QA

Use this skill to catch mobile problems that make otherwise premium sites feel rushed.

Workflow

  1. Inspect the affected surface, relevant project scripts, target URL and available inspection tooling; reuse existing context.
  2. Read Mobile Responsive QA Guide before claiming the site is ready.
  3. Run the narrowest meaningful checks for the risk: visual, mobile, accessibility, performance, forms, media, SEO, analytics, deployment, or handoff.
  4. Fix issues when they are in scope; otherwise record exact evidence and remaining risk.
  5. Summarize commands, URLs, screenshots/checks, changed files, and what was not tested.

Scoped execution

Apply the shared web contract once when execution crosses phases; reuse it if already read. Load only the specialist guidance relevant to the requested surface and deliverable.

Scope and evidence

Record width emulation separately from real touch/device/virtual-keyboard evidence. Use $responsive-visual-polish-qa for broad breakpoint composition; do not claim real-device certification from emulation.

Files

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.
