infinity — Input Boundary & Validation Protocol

Core Philosophy

Nothing untrusted ever reaches the core — it is stopped before contact. No external data touches the codebase raw. Every boundary where data enters the system must have a filter.

The #1 source of silent bugs, crashes, and vulnerabilities is external data that arrives in an unexpected shape and gets used directly without checking. This skill enforces a filter layer at every entry point, every time.

When to Use This Skill

• Use when you need to handle an API response
• Use when reading user input or adding a form handler
• Use when working with environment variables or CLI arguments
• Use when parsing webhooks or reading from the filesystem
• Use when any code calls .body, .params, .query, .env, fs.read, or a third-party SDK response
