code-harden-types

What problem does it solve?

This Skill reduces runtime bugs and type regressions by removing weak typing patterns in the parts of a codebase that most often accept untrusted input.

Core Features & Use Cases

• Types hardening for changed files: Focuses on the current diff to tighten safety without broad refactors.
• Boundary validation with the existing validator: Adds zod-based validation (or whichever validator the project already uses) at trust boundaries like HTTP handlers, server functions, webhook payloads, and job/queue handlers.
• Safe, classified remediation: Automatically fixes clearly mechanical issues (e.g., redundant casts and suppressed type errors) while surfacing structural risks for human review.

Quick Start

Run the code-harden-types skill on your current changed TypeScript files to remove any unsafe typing and enforce runtime validation at input boundaries.
