Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned aj-geddes/useful-ai-prompts at 3f5182cfd7.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill enables AI agents to automatically validate user input within web forms against specific criteria before submission. It ensures data integrity by checking for required fields, correct formats, and logical consistency in real-time.

When to use it

  • Prevent invalid submissions: Stop users from submitting incomplete or malformed data to backend systems.
  • Enhance user experience: Provide immediate feedback on errors so users can correct inputs instantly without page reloads.
  • Secure sensitive data: Enforce strict patterns for emails, phone numbers, or passwords before they reach your database.
  • Streamline workflows: Automate validation logic in chatbots or automated assistants handling registration or order forms.

Key capabilities

  • Validates required fields to ensure no empty submissions occur.
  • Checks input formats (e.g., email regex, date ranges).
  • Performs cross-field validation (e.g., end date must be after start date).
  • Returns structured error messages for specific field failures.

Example prompts

  • "Validate this contact form submission and list any errors with the field names."
  • "Check if the user's input matches the required pattern for a valid email address."
  • "Run validation rules on these order details before processing the transaction."

Tips & gotchas

Ensure your AI agent has access to the specific validation rules (regex patterns, logic constraints) relevant to your application context. This skill does not replace backend security; always re-validate critical data server-side after initial client-side checks.
