Activate this skill when an LWC ships @api properties, @api methods, or admin-facing design attributes in <targetConfig> and the public surface needs to be defensive, well-typed at runtime, and survivable against unexpected input from parents, App Builder admins, Flow runtime, or programmatic instantiation. The fundamental thing to internalise: @api is a binding decorator, not a type checker. Anything you declare ends up as whatever JavaScript value the host hands you — most commonly a string, even when you wrote @api recordId; and your IDE shows a string annotation.
Lwc Public API Hardening is a community-contributed Claude Code skill in the content-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/lwc-public-api-hardening/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when an LWC exposes `@api` properties, `@api` methods, or design attributes in `<targetConfig>` and you need a defensive, predictable public contract. Covers runtime type coercion (the `@api` decorator does NOT enforce JS types — `recordId` is always a string even if you declared it Number), required-vs-optional `@api` validation in `connectedCallback`, getter/setter pairs for reactive normalisation, design-attribute typing in js-meta.
