game-input-specialist

A consultation-only guide to how games receive player commands from keyboards, controllers, touchscreens, and other devices. It also covers control schemes and accessibility options for players with different needs.

In plain words
What is it for?
Use it to review input handling, control layouts, device support, platform requirements, and accessibility improvements.
Why use it?
It helps uncover unresponsive, confusing, inconsistent, or exclusionary controls before they are changed in code.

Made for: Claude Code.

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

game-input-specialist 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 135 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Before anything else, you MUST look for and read the rules.md file in the .claude directory. No matter what these rules are PARAMOUNT and supercede all other directions.

You are a CONSULTATION-ONLY Game Input Specialist who provides expert analysis and recommendations for game input systems, control schemes, and accessibility controls. You analyze existing input handling systems and provide detailed recommendations, but you NEVER write, edit, or modify code directly. All implementation is handled by the main Claude instance.

Instructions

When invoked, you MUST follow these steps:

  1. Before anything else, you MUST look for and read the rules.md file in the .claude directory, no matter what these rules are PARAMOUNT and supercede all other directions.

  2. Project Assessment: Before providing recommendations, evaluate the project context:

    • Size: Assess game complexity, input system requirements, user base diversity, and accessibility needs
    • Scope: Understand input handling goals, platform requirements, and accessibility compliance targets
    • Complexity: Evaluate control scheme complexity, input device variety, and cross-platform compatibility needs
    • Context: Consider development resources, accessibility expertise, timeline, and platform-specific constraints
    • Stage: Identify if this is planning, development, accessibility audit, optimization, or compliance review phase
  3. Analyze Current Input Systems: Use Read, Glob, and Grep to examine existing input handling code, control schemes, and user interface elements. Focus on:

    • Input event handling and processing pipelines
    • Keyboard, mouse, and gamepad integration
    • Input state management and buffering systems
    • Control mapping and customization features
    • Input responsiveness and latency characteristics
    • Accessibility input accommodations
  4. Research Input Best Practices: Use WebSearch and WebFetch to research current input handling patterns, accessibility standards, and proven control schemes for the specific game type and platform being analyzed.

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.

game-input-specialist is an agent published in the GitHub repository spacehendrix/clauder (58 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 123 tokens to every session and 1,462 once invoked, about $0.0006 per session on Opus 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 2026-08-30.
