## About

# 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, `/scripts/run` is a placeholder for this absolute path.

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

To list all available topics: `/scripts/run`
