chatcli: Skill for Claude Code

.agent/skills/game-development/mobile-games/SKILL.md

mobile-games is a skill for Claude Code from diillson/chatcli. It costs 18 tokens per session (521 once invoked), scanned A, a copy of mobile-games, Apache-2.0.

A set of guidelines for building mobile games, including touch controls, battery use, heat, different screen sizes, interruptions, and app-store requirements.

In plain words
What is it for?
Use it when designing touch interactions, responsive game screens, performance limits, battery behavior, pause handling, and store submissions.
Why use it?
It helps account for restrictions that do not apply in the same way on desktop computers or game consoles.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter.

This is diillson/chatcli's own configuration. It tells Claude Code how to work on chatcli 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 chatcli 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-games 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 1mo 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 Game Development

Platform constraints and optimization principles.


1. Platform Considerations

Key Constraints

Constraint Strategy
Touch input Large hit areas, gestures
Battery Limit CPU/GPU usage
Thermal Throttle when hot
Screen size Responsive UI
Interruptions Pause on background

2. Touch Input Principles

Touch vs Controller

Touch Desktop/Console
Imprecise Precise
Occludes screen No occlusion
Limited buttons Many buttons
Gestures available Buttons/sticks

Best Practices

  • Minimum touch target: 44x44 points
  • Visual feedback on touch
  • Avoid precise timing requirements
  • Support both portrait and landscape

3. Performance Targets

Thermal Management

Action Trigger
Reduce quality Device warm
Limit FPS Device hot
Pause effects Critical temp

Battery Optimization

  • 30 FPS often sufficient
  • Sleep when paused
  • Minimize GPS/network
  • Dark mode saves OLED battery

4. App Store Requirements

iOS (App Store)

Requirement Note
Privacy labels Required
Account deletion If account creation exists
Screenshots For all device sizes

Android (Google Play)

Requirement Note
Target API Current year's SDK
64-bit Required
App bundles Recommended

5. Monetization Models

Model Best For
Premium Quality games, loyal audience
Free + IAP Casual, progression-based
Ads Hyper-casual, high volume
Subscription Content updates, multiplayer

6. Anti-Patterns

❌ Don't ✅ Do
Desktop controls on mobile Design for touch
Ignore battery drain Monitor thermals
Force landscape Support player preference
Always-on network Cache and sync

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.
