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 an AI agent to verify that a TypeScript switch statement or similar construct handles all possible cases of a discriminated union. It ensures no potential values are missed, preventing runtime errors and improving code reliability. The skill provides feedback on whether the exhaustive check passed or failed, highlighting any missing cases.

When to use it

  • Code Review: Automatically assess TypeScript code for exhaustiveness in switch statements when reviewing pull requests.
  • Refactoring: Identify potential issues during refactoring of existing TypeScript codebases that utilize discriminated unions.
  • Learning/Debugging: Help developers understand and debug type errors related to incomplete pattern matching.
  • Automated Testing: Integrate into CI/CD pipelines to ensure exhaustiveness checks are consistently enforced.

Key capabilities

  • Analyzes switch statements with discriminated union types.
  • Identifies missing cases in the switch statement.
  • Provides feedback on whether the exhaustive check passed or failed.

Example prompts

  • "Check if this TypeScript code is exhaustively handling all possible values of the 'Status' type." [followed by code]
  • “Analyze this switch statement for completeness regarding the 'Shape' union.” [followed by code]
  • "Can you verify that this switch block covers all cases in my 'Fruit' discriminated union?" [followed by code]

Tips & gotchas

This skill requires valid TypeScript code as input. It is most effective when dealing with explicit discriminated unions; implicit or complex union types might yield less accurate results.
