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 marius-townhouse/effective-typescript-skills at d754db2077.

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

About this skill

What it does

This skill allows you to apply the exclusive-or (XOR) principle when defining TypeScript properties. It enables a set of properties to be present, but only one can have a value at any given time, ensuring data integrity and preventing conflicting states within your code. This is particularly useful for representing mutually exclusive options or configurations.

When to use it

  • Representing Mutually Exclusive Options: When an object has several possible settings where only one can be active (e.g., a payment method with 'credit_card', 'paypal', and 'bank_transfer').
  • Configuration Management: Defining configuration options where certain features are incompatible and cannot be enabled simultaneously.
  • State Machines: Modeling states in a state machine where transitions between states enforce that only one state is active at a time.

Key capabilities

  • Enforces exclusive property values.
  • Provides type safety for mutually exclusive properties.
  • Reduces potential errors related to conflicting configurations.

Example prompts

  • "Apply XOR constraints to the paymentMethod object, ensuring only one of 'credit_card', 'paypal', or 'bank_transfer' can have a value."
  • "Create a configuration with exclusive options for feature flags A and B; only one can be true at a time."
  • "Define a state machine where the state property can only be 'idle', 'loading', or 'error' simultaneously."

Tips & gotchas

This skill requires a good understanding of TypeScript types and generics. Incorrectly defining the properties involved in the XOR relationship can lead to unexpected behavior, so careful consideration is needed during implementation.
