Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install aspnet-core-validation-fluentvalidation

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent adds Data Annotations to models, writes FluentValidation validators for complex rules and wires the validation filter to endpoints. You get consistent input validation and clear error messages.
