You can exclude specific files from AI analysis using the --exclude flag:

`sh
lazycommit --exclude package-lock.json --exclude dist/
`

#### Handling large diffs

For large commits with many files, lazycommit automatically stays within API limits and generates relevant commit messages:

- Smart summarization: Uses git diff --cached --numstat to create compact summaries of all changes
- Context snippets: Includes truncated diff snippets from top changed files for better context
- Token-safe processing: Keeps prompts small while maintaining accuracy for 20+ file changes
- Single commit: Always generates one commit message, no matter how many files are staged
- Enhanced analysis: Uses improved prompts and smart truncation for better commit message quality

$3

You can also integrate _lazycommit_ with Git via the prepare-commit-msg hook. This lets you use Git like you normally would, and edit the commit message before committing. The hook uses the same enhanced analysis and quality improvements as the CLI mode.

#### Install

In the Git repository you want to install the hook in:

`sh
lazycommit hook install
`

#### Uninstall

In the Git repository you want to uninstall the hook from:

`sh
lazycommit hook uninstall
`

#### Usage

1. Stage your files and commit:

`sh
git add
git commit # Only generates a message when it's not passed in
`

> If you ever want to write your own message instead of generating one, you can simply pass one in: git commit -m "My message"

2. Lazycommit will generate a high-quality commit message using the same enhanced analysis as the CLI mode and pass it back to Git. Git will open it with the configured editor for you to review/edit it.

3. Save and close the editor to commit!

Configuration

$3

To retrieve a configuration option, use the command:

`sh
lazycommit config get
`

For example, to retrieve the API key, you can use:

`sh
lazycommit config get GROQ_API_KEY
`

You can also retrieve multiple configuration options at once by separating them with spaces:

`sh
lazycommit config get GROQ_API_KEY generate
`

$3

To set a configuration option, use the command:

`sh
lazycommit config set =
`

For example, to set the API key, you can use:

`sh
lazycommit config set GROQ_API_KEY=
`

You can also set multiple configuration options at once by separating them with spaces, like

`sh
lazycommit config set GROQ_API_KEY= generate=3 locale=en
`

$3

#### GROQ_API_KEY

Required

The Groq API key. You can retrieve it from Groq Console.

#### locale

Default: en

The locale to use for the generated commit messages. Consult the list of codes in: https://wikipedia.org/wiki/List_of_ISO_639-1_codes.

#### generate

Default: 1

The number of commit messages to generate to pick from.

Note, this will use more tokens as it generates more results.

#### proxy

Set a HTTP/HTTPS proxy to use for requests.

To clear the proxy option, you can use the command (note the empty value after the equals sign):

`sh
lazycommit config set proxy=
`

#### model

Default: openai/gpt-oss-20b

The Groq model to use for generating commit messages. Available models include:
- openai/gpt-oss-20b (default) - Fast, efficient for conventional commits

For conventional commit generation, the 8B instant model provides the best balance of speed and quality.

#### timeout

The timeout for network requests to the Groq API in milliseconds.

Default: 10000 (10 seconds)

`sh
lazycommit config set timeout=20000 # 20s
`

#### max-length

The maximum character length of the generated commit message.

Default: 100

`sh
lazycommit config set max-length=150
`

#### type

Default: "" (Empty string)

The type of commit message to generate. Set this to "conventional" to generate commit messages that follow the Conventional Commits specification:

`sh
lazycommit config set type=conventional
`

You can clear this option by setting it to an empty string:

`sh
lazycommit config set type=
`

How it works

This CLI tool runs git diff to grab all your latest code changes, sends them to Groq's AI models, then returns the AI generated commit message.

The tool uses Groq's fast inference API to provide quick and accurate commit message suggestions based on your code changes.

$3

For large commits that exceed API token limits, lazycommit automatically:

1. Detects large/many-file diffs and switches to enhanced analysis mode
2. Creates compact summaries using git diff --cached --numstat to capture all changes efficiently
3. Includes context snippets from the most changed files to provide semantic context
4. Generates a single commit message that accurately reflects all changes without hitting API limits
5. Smart truncation preserves sentence structure and meaning when messages approach length limits
6. Enhanced prompts provide better context for AI to generate complete, professional commit messages

This ensures you can commit large changes (like new features, refactoring, or initial project setup) without hitting API limits, while maintaining accuracy, relevance, and high-quality commit messages.

Troubleshooting

$3

If you get a 413 error, your diff is too large for the API. Try these solutions:

1. Exclude build artifacts:
`sh
lazycommit --exclude "dist/" --exclude "node_modules/" --exclude ".next/**"
`

2. Use a different model:
`sh
lazycommit config set model "llama-3.1-70b-versatile"
`

3. Commit in smaller batches:
`sh
git add src/ # Stage only source files
lazycommit
git add docs/ # Then stage documentation
lazycommit
`

$3

- Check your API key: lazycommit config get GROQ_API_KEY
- Verify you have staged changes: git status
- Try excluding large files or using a different model

$3

- Use the GPT-OSS-20B model (default): lazycommit config set model "openai/gpt-oss-20b"
- Exclude unnecessary files: lazycommit --exclude ".log" --exclude ".tmp"
- Use the built-in large diff handling for better context and accuracy
- Lower generate count: lazycommit config set generate=1 (default)
- Reduce timeout: lazycommit config set timeout=5000` for faster failures

Why Groq?

- Fast: Groq provides ultra-fast inference speeds, especially with the 8B instant model
- Cost-effective: More affordable than traditional AI APIs
- Open source models: Uses leading open-source language models
- Reliable: High uptime and consistent performance
- Optimized for commits: The 8B instant model is perfectly sized for conventional commit generation
