Automated safety checks
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.

About this skill
What it does
This skill enables AI agents to assist with advanced state management in React applications using Zustand. It provides guidance and code examples for implementing complex patterns such as transient updates (updating state without re-renders), subscriptions to specific parts of the state, and optimistic UI updates that improve perceived performance during server interactions. The skill focuses on leveraging these techniques within a Zustand store.
When to use it
- When you need to update application state without triggering unnecessary re-renders in React components.
- When you want to react to changes in only specific parts of your Zustand store's data.
- When implementing features that require optimistic updates, such as adding or deleting items before server confirmation.
Key capabilities
- Transient Updates: Updating state without triggering re-renders using the
set(..., false)pattern. - Subscriptions with Selectors: Subscribing to specific slices of Zustand store data and reacting only when those values change.
- Optimistic Updates: Implementing optimistic UI updates, immediately reflecting changes in the UI and then synchronizing with a server, including rollback mechanisms on error.
Example prompts
- "Show me how to update my Zustand count without re-rendering."
- "Can you give me an example of subscribing to only the 'todos' slice of my store?"
- "How can I implement optimistic updates when adding a new todo item using Zustand?"
Tips & gotchas
- This skill assumes familiarity with basic React and Zustand concepts.
- Optimistic updates require careful error handling to rollback changes if the server request fails.
- Transient state updates should be used judiciously, as they can make debugging more difficult if not properly managed.
