FastCommit

AI-powered commit message generator for VS Code that creates conventional commit messages based on your staged changes.

README.md

# Ignore test files
**/*.test.js
**/*.spec.ts

How It Works

1. Analyzes Changes: FastCommit examines your staged Git changes
2. Generates Context: Creates a comprehensive diff and repository context
3. AI Processing: Sends context to your chosen AI provider
4. Formats Output: Ensures the response follows conventional commit standards
5. Sets Message: Automatically populates the Git commit message field

Conventional Commit Format

FastCommit generates messages following the Conventional Commits specification:

<type>[optional scope]: <description>

[optional body]

[optional footer(s)]
