ts-patterns

This skill provides reference information on demand.

MCP mode (preferred)

If you have MCP tools for this skill (e.g., mcp__ts-patterns__topic), use them:

Call topics to list available reference topics.
Call topic with a topic name to retrieve its content.

Present the content to the user. Do not show raw tool calls.

CLI mode (fallback)

Resolve the absolute path to scripts/run from this SKILL.md file’s directory. Use the absolute path in all commands — do not cd into the skill directory. In the examples below, <skill>/scripts/run is a placeholder for this absolute path.

<skill>/scripts/run topic generics — Generics cheat sheet — constraints, conditional types, mapped types, infer
<skill>/scripts/run topic discriminated-unions — Discriminated unions — type narrowing with literal discriminants
<skill>/scripts/run topic builder-pattern — Builder pattern — fluent APIs with type accumulation
<skill>/scripts/run topic error-handling — Error handling — Result types, custom errors, exhaustive matching

To list all available topics: <skill>/scripts/run
