Flow

Use when you need to run Flow type checking, or when seeing Flow type errors in React code.

$ npx promptcreek add flow

Auto-detects your installed agents and installs the skill to each one.

What This Skill Does

This skill guides developers in using Flow for type checking in React projects. It provides instructions on how to run Flow with different renderers and report type errors. It helps ensure code correctness and prevent runtime errors by enforcing static typing.

When to Use

  • Preventing runtime errors.
  • Enforcing type safety.
  • Improving code maintainability.
  • Catching type-related bugs early.
  • Adding type annotations to existing code.
  • Refactoring code with type checking.

Key Features

Performs Flow type checking.
Supports multiple renderers (dom-node, dom-browser, native, fabric).
Reports type errors with file locations.
Provides `yarn flow` command for checking.
Offers `yarn flow-ci` for comprehensive checking.
Helps identify and fix type-related issues.

Installation

Run in your project directory:
$ npx promptcreek add flow

Auto-detects your installed agents (Claude Code, Cursor, Codex, etc.) and installs the skill to each one.

Flow Type Checking

Arguments:

  • $ARGUMENTS: Renderer to check (default: dom-node)

Renderers

| Renderer | When to Use |

|----------|-------------|

| dom-node | Default, recommended for most changes |

| dom-browser | Browser-specific DOM code |

| native | React Native |

| fabric | React Native Fabric |

Instructions

  • Run yarn flow $ARGUMENTS (use dom-node if no argument)
  • Report type errors with file locations
  • For comprehensive checking (slow), use yarn flow-ci

Common Mistakes

  • Running without a renderer - Always specify or use default dom-node
  • Ignoring suppressions - Check if $FlowFixMe comments are masking real issues
  • Missing type imports - Ensure types are imported from the correct package
