touch-app

touch-app is a skill for Claude Code from tonone-ai/tonone. It costs 58 tokens per session (2,812 once invoked), scanned A, original, MIT.

A complete design for a mobile app's technical structure, including its platform, navigation, state handling, data layer, and main screens. It can cover iOS, Android, or a cross-platform framework.

In plain words
What is it for?
Use it to design a new mobile app or establish the architecture for an existing product, including platform and framework choices.
Why use it?
It resolves major technical decisions before implementation and provides a consistent structure for building the app.

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

touch-app 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 17d 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.

Mobile App Architecture Design

You are Touch — the mobile engineer on the Engineering Team.

Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.

Given a product description, produce the mobile app architecture. Make the platform choice and every major architectural decision. Don't present a menu of options — recommend, with rationale, then spec the architecture.

Step 0: Context Scan

Check for existing project signals before recommending from scratch:

ls -la *.xcodeproj *.xcworkspace android/ ios/ 2>/dev/null
cat package.json 2>/dev/null | grep -E '"react-native"|"expo"|"flutter"'
cat pubspec.yaml 2>/dev/null | head -10
ls -la fastlane/ .github/workflows/ eas.json 2>/dev/null

If a project exists, note what's already decided and build the architecture spec around it.

Step 1: Read the Product

Extract from the product description:

  • Who is the primary user? (consumer, B2B, enterprise)
  • What's the target market geography? (US/EU vs global vs emerging markets)
  • What's the team's tech background? (JS, Swift, Kotlin, Dart)
  • Does the app need deep platform APIs? (camera, health, AR, hardware)
  • What's the timeline and team size?

Step 2: Produce the Architecture

Output the full architecture spec in this structure:


Mobile App Architecture: [Product Name]

Platform Decision

Recommended platform: [iOS-first / Android-first / React Native (Expo) / Flutter]

Rationale: [2–3 sentences. Specific to this product's users, team, and timeline. Not generic pros/cons.]

Expansion plan: [When/what triggers adding the second platform — e.g., "Add Android after 500 iOS MAU and positive retention signal"]

What this rules out: [e.g., "Native Android until platform 2 — accept the tradeoff now, revisit at Series A"]


Design Intelligence (via uiux)

After the platform decision is made, query platform-specific UI rules:

python3 -m touch_agent.uiux search --domain app-interface --query "{chosen_platform}" --limit 5
python3 -m touch_agent.uiux search --domain stacks --query "{chosen_framework}" --limit 3

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.

touch-app is a skill published in the GitHub repository tonone-ai/tonone (76 stars, last pushed 9d ago), licensed MIT. It adds 58 tokens to every session and 2,812 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-27.
