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 process data streams and manage state changes dynamically without blocking the main thread. It facilitates building responsive user interfaces that update automatically when underlying data shifts, ensuring a smooth and immediate user experience.

When to use it

  • Real-time dashboards: Update charts or metrics instantly as new data arrives from APIs or sensors.
  • Interactive forms: Validate inputs and display error messages immediately as the user types, rather than waiting for submission.
  • Live collaboration: Reflect changes made by multiple users in a shared document or whiteboard without page reloads.
  • Dynamic filtering: Adjust search results or list views instantly based on user-selected filters or keywords.

Key capabilities

  • Handles asynchronous data streams efficiently.
  • Manages complex state transitions reactively.
  • Prevents race conditions in UI updates.
  • Enables declarative programming for frontend logic.

Example prompts

  • "Create a real-time stock ticker component that updates every second using reactive streams."
  • "Build a form validator that triggers error animations immediately when invalid data is entered."
  • "Design a chat interface where new messages appear instantly without refreshing the page."

Tips & gotchas

Ensure your application has a stable event loop to avoid performance bottlenecks with heavy computations. Avoid mixing imperative DOM manipulation directly within reactive callbacks, as this can lead to unpredictable state updates.
