Enforces a strict input boundary protocol (detect, classify, filter, verify) to ensure untrusted data never reaches business logic raw.

Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# 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 --- ## The Four Phases ### PHASE 1 — Boundary Detection Before writing or modifying any code that involves external data, the AI must identify and list every entry point in scope: - HTTP request bodies, headers, query params - User form inputs and UI-submitted data - Environment variables and config files - Third-party API responses - Webhook payloads - File reads fro

What does the infinity skill do?
Enforces a strict input boundary protocol (detect, classify, filter, verify) to ensure untrusted data never reaches business logic raw.
How do I install it?
Run `npx skills add sickn33/agentic-awesome-skills --skill infinity --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From sickn33/agentic-awesome-skills, a repository with 44,414 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
