⬇️ Installation

To use GPTComet, you can install it with Homebrew:

brew install belingud/tap/gptcomet

To upgrade a Homebrew-managed installation, use:

brew upgrade gptcomet

You can also download from Github release, or by install scripts:

curl -sSL https://cdn.jsdelivr.net/gh/belingud/gptcomet@master/install.sh | bash

Windows:

irm https://cdn.jsdelivr.net/gh/belingud/gptcomet@master/install.ps1 | iex

If you want to install specific version, you can use the following script:

curl -sSL https://cdn.jsdelivr.net/gh/belingud/gptcomet@master/install.sh | bash -s -- -v 0.4.2
irm https://cdn.jsdelivr.net/gh/belingud/gptcomet@master/install.ps1 | iex -CommandArgs @("-v", "0.4.2")

If you prefer to run in python, you can install by pip directly, it packaged the binary files corresponding to the platform already.

pip install gptcomet

# Using pipx
pipx install gptcomet

# Using uv
uv tool install gptcomet
Resolved 1 package in 1.33s
Installed 1 package in 8ms
 + gptcomet==0.1.6
Installed 2 executables: gmsg, gptcomet

📕 Usage

To use gptcomet, follow these steps:

  1. Install GPTComet: Install GPTComet through pypi.
  2. Configure GPTComet: See Setup. Configure GPTComet with your api_key and other required keys like:
  • provider: The provider of the language model (default openai).
  • api_base: The base URL of the API (default https://api.openai.com/v1).
  • api_key: The API key for the provider.
  • model: The model used for generating commit messages (default gpt-6.1-sol).
  1. Run GPTComet: Run GPTComet using the following command: gmsg commit.

If you are using openai provider, and finished set api_key, you can run gmsg commit directly.

🔧 Setup

Configuration Methods

  1. Direct Configuration

    • Configure directly in ~/.config/gptcomet/gptcomet.yaml.
  2. Interactive Setup

    • Use the gmsg provider new command for guided setup (gmsg newprovider is deprecated and will be removed in v2.14.0; see Deprecations).
  3. Environment Variables

    • If api_key is not set in the configuration file, GPTComet falls back to the provider's conventional environment variable, such as OPENAI_API_KEY, ANTHROPIC_API_KEY, GEMINI_API_KEY, AZURE_API_KEY, or <PROVIDER>_API_KEY for other providers.
    • The configuration file takes precedence when both are set.

Managing Providers

Inspect the active provider and every known provider, switch the default, and verify a provider with one minimal request:

gmsg provider list     # active provider, model, API base, and API key source
gmsg provider use claude
gmsg provider test      # probe the active provider; or: gmsg provider test deepseek

gmsg provider list shows where each provider's API key comes from:

  • config (sk-ab***) — set in gptcomet.yaml (masked in the output);
  • env OPENAI_API_KEY — the config value is empty and the built-in environment variable is set;
  • not required — local providers such as ollama and lmstudio;
  • missing — no key found; commands that call the provider fail until one is set.

gmsg provider use <name> switches the default provider and creates a default configuration block for a built-in provider that does not have one yet. It never overwrites an existing block, and it warns when the API key or a provider-specific field (for example azure.deployment_name) is still missing. Configured custom providers keep working through the OpenAI-compatible fallback.

gmsg provider test [provider] sends exactly one small request without retries, using the provider's saved configuration, and reports the model, API base, key source, latency, and a short response. It exits non-zero when the request fails and prints an actionable error (invalid key, rate limit, provider outage, or network/proxy problem). It does not need a Git repository.

To add or reconfigure a provider interactively, use gmsg provider new (gmsg newprovider is deprecated and will be removed in v2.14.0; see Deprecations).

This is also the escape hatch for any OpenAI-compatible service that GPTComet does not ship a preset for: enter a custom provider name, then set its api_base, model, and api_key. Advanced users can also set completion_path, answer_path, stream_answer_path, extra_headers, and extra_body for non-standard APIs.

Cloudflare Workers AI is a built-in provider now. Select cloudflare in gmsg provider new and enter your account ID, API token, and Workers AI model (for example @cf/openai/gpt-oss-120b); GPTComet builds the OpenAI-compatible endpoint for you. The old /ai/run + result.response manual workaround is no longer needed.

🪝 Git Hook

Install the hook once per repository:

gmsg hook install
gmsg hook status

The managed prepare-commit-msg hook generates a message from the staged diff before the editor opens. It fails open: if gptcomet is missing, the configuration is invalid, there is no staged diff, or the API call fails or times out, the commit message file is left unchanged and the commit continues.

gmsg hook uninstall          # remove the managed hook
gmsg hook install --force    # back up and replace an existing hook

Behavior:

  • Skips git commit -m / -F, merges, squash commits, and git commit --amend.
  • Skips when the message file already has non-comment content. The all-comment template used by the first commit is still filled; a custom template with real content is left untouched.
  • GMSG_SKIP=1 skips the hook entirely.
  • GMSG_FORCE=1 overrides the explicit-message and existing-content skips.
  • GMSG_BIN=/path/to/gmsg selects the binary; GMSG_CONFIG=/path/to/config.yaml selects the configuration file. gmsg hook install -c <config> embeds that config path in the hook.
  • gmsg hook install --force backs up an existing hook to prepare-commit-msg.gptcomet-backup; gmsg hook uninstall restores it.
  • The hooks directory is resolved with git rev-parse, so core.hooksPath and linked worktrees are respected.
  • Generation is synchronous, so the editor opens after the model responds; the configured <provider>.timeout bounds the wait.
  • git commit --no-verify does not skip prepare-commit-msg; use GMSG_SKIP=1 instead.

To preview the exact message without committing:

gmsg generate
gmsg generate --rich

generate writes only the message to stdout; status and token-usage output goes to stderr, so it is safe to use in scripts. See Scripting and exit codes for the full contract.

🧩 Scripting and exit codes

GPTComet separates results from status so it can be used inside scripts, editor plugins, and CI:

  • stdout carries only the result: the commit message from gmsg generate, the review from gmsg review (rendered, or verbatim Markdown with --raw), and the previewed message from gmsg commit --dry-run.
  • stderr carries status: provider/model banner, progress, reminders, token usage, warnings, prompts, and errors. Secret-scan findings are always on stderr and are masked.
gmsg generate > commit-msg.txt          # only the message ends up in the file
gmsg review --raw > review.md           # raw model Markdown, no rendering or border
gmsg review --stream | pbcopy           # stream the review; status stays out of the pipe
git commit -F commit-msg.txt            # use the generated message directly

gmsg commit is interactive: its prompts, message previews, and commit summary stay on stderr, and nothing is written to stdout. --raw only affects the non-stream review path; streamed chunks are already unformatted.

Exit codes classify failures so scripts can distinguish them:

Code Meaning
0 Success
1 Unexpected or unclassified error
2 Command-line usage error (unknown flag or invalid flag value)
3 Configuration error (missing provider/API key, invalid config)
4 Network, proxy, or connection error
5 Git/VCS error, including "no staged changes"
6 API/LLM error (request rejected, response parsing, retries exhausted)
7 Validation/content error, including a diff blocked by sensitive.mode=block

Scripts that only check "non-zero means failure" keep working; the fine-grained codes are for choosing remediation or gating CI. Hook management commands (gmsg hook install/uninstall/status) are human-facing and keep their current stdout output.

⚙ Configuration

Here's a summary of the main configuration keys:

Key Description Default Value
provider The name of the LLM provider to use. openai
file_ignore A list of file patterns to ignore in the diff. (See file_ignore)
sensitive.mode Pre-send secret scanning mode: off, warn, redact, or block. warn
sensitive.allow Regex allowlist matched against a finding's secret or line; matches are ignored. []
output.lang The language for commit message generation. en
output.rich_template The template to use for rich commit messages. <title>:<summary>\n\n<detail>
output.translate_title Translate the title of the commit message. false
output.review_lang The language to generate the review message. en
output.markdown_theme The theme to display markdown_theme content. auto
console.verbose Enable verbose output with progress indicators and detailed error messages. true
<provider>.api_base The API base URL for the provider. (Provider-specific)
<provider>.api_key The API key for the provider.
<provider>.model The model name to use. (Provider-specific)
<provider>.retries The number of retry attempts for API requests. 2
<provider>.timeout Request timeout in seconds. Non-streaming calls use it as a total deadline; streaming calls use it as an idle timeout that resets whenever content arrives. 60
<provider>.proxy The proxy URL to use (if needed).
<provider>.max_tokens The maximum number of tokens to generate. 2048
<provider>.top_p The top-p value for nucleus sampling. 0.7
<provider>.temperature The temperature value for controlling randomness. 0.7
<provider>.frequency_penalty The frequency penalty value. 0
<provider>.extra_headers Extra headers to include in API requests (JSON string). {}
<provider>.extra_body Extra body to include in API requests (JSON string). {}
<provider>.completion_path The API path for completion requests. (Provider-specific)
<provider>.answer_path The JSON path to extract the answer from the API response. (Provider-specific)
prompt.brief_commit_message The prompt template for generating brief commit messages. (See defaults/defaults.go)
prompt.rich_commit_message The prompt template for generating rich commit messages. (See defaults/defaults.go)
prompt.translation The prompt template for translating commit messages. (See defaults/defaults.go)
prompt.review The prompt template for reviewing code changes. (See defaults/defaults.go)

Note: <provider> should be replaced with the actual provider name (e.g., openai, gemini, claude).

Some providers require specific keys, such as Vertex needing project ID, location, etc.

The configuration file for GPTComet is gptcomet.yaml. The file should contain the following keys:

output.translate_title is used to determine whether to translate the title of the commit message.

For example in output.lang: zh-cn, the title of the commit message is feat: Add new feature

If output.translate_title is set to true, the commit message will be translated to 功能:新增功能. Otherwise, the commit message will be translated to feat: 新增功能.

In some case you can set complation_path to empty string, like <provider>.completion_path: "", to use api_base endpoint directly.

file_ignore

The file to ignore when generating a commit. The default value is

- bun.lockb
- Cargo.lock
- composer.lock
- Gemfile.lock
- package-lock.json
- pnpm-lock.yaml
- poetry.lock
- yarn.lock
- pdm.lock
- Pipfile.lock
- "*.py[cod]"
- go.sum
- uv.lock

You can add more file_ignore by using the gmsg config append file_ignore <xxx> command. <xxx> uses gitignore-style patterns:

  • *.lock matches a.lock and vendor/a.lock (a pattern without / matches at any depth).
  • vendor/** matches everything under vendor/, and docs/*.md matches only direct children of docs/.
  • /go.sum matches only the repository-root go.sum; go.sum matches it at any depth.
  • build/ matches a directory named build and everything below it.
  • !important.lock re-includes a file matched by an earlier pattern.

Example:

gmsg config append file_ignore "vendor/**"
gmsg config append file_ignore "!vendor/keep.go"

sensitive data scanning

Before any diff is sent to a provider, GPTComet scans the added lines for credentials with a lightweight engine loaded from the MIT-licensed gitleaks rule data (222 rules, vendored under internal/secretscan/rules/). It never changes your staged diff; only the text sent to the model can be rewritten.

sensitive:
  mode: warn      # off | warn | redact | block
  allow: []       # regexes matched against the secret or the full line
Mode Behavior
off No scanning.
warn (default) Send the diff unchanged and print masked findings to stderr.
redact Replace secret spans with [REDACTED:<rule>] before sending.
block Send nothing and exit with a structured error.

Sensitive file names (.env*, private key material, credentials.json, .npmrc, .pypirc, .netrc) are flagged even when no per-line regex matches. Silence known false positives with sensitive.allow, or a single line with a gitleaks:allow comment. The Git hook stays fail-open: in block mode it prints the warning but does not block git commit.

Override the mode for one command (all commands that send a diff):

gmsg commit --secrets redact
gmsg generate --secrets off
gmsg review --secrets block

Not detected: secrets hidden inside base64/hex blobs, git history, or archive contents — this is a pre-send guard, not a replacement for gitleaks/GitHub secret scanning in CI.

provider

The provider configuration of the language model.

The default provider is openai. You can inspect and switch it with gmsg provider list and gmsg provider use <name>, and verify the configuration with gmsg provider test.

Provider config just like:

provider: openai
openai:
    api_base: https://api.openai.com/v1
    api_key: YOUR_API_KEY
    model: gpt-6.1-sol
    retries: 2
    max_tokens: 1024
    temperature: 0.7
    top_p: 0.7
    frequency_penalty: 0
    extra_headers: {}
    answer_path: choices.0.message.content
    completion_path: /chat/completions

If you are using openai, just leave the api_base as default. Set your api_key in the config section.

If you are using an openai class provider, or a provider compatible interface, you can set the provider to openai. And set your custom api_base, api_key and model.

For example:

Openrouter providers api interface compatible with openai, you can set provider to openai and set api_base to https://openrouter.ai/api/v1, api_key to your api key from keys page and model to openai/gpt-6.1-sol or some other you prefer.

gmsg config set openai.api_base https://openrouter.ai/api/v1
gmsg config set openai.api_key YOUR_API_KEY
gmsg config set openai.model openai/gpt-6.1-sol
gmsg config set openai.max_tokens 1024

Silicon providers the similar interface with openrouter, so you can set provider to openai and set api_base to https://api.siliconflow.cn/v1.

Note that max tokens may vary, and will return an error if it is too large.

output

The output configuration of the commit message.

The default output is

output:
    lang: en
    rich_template: "<title>:<summary>\n\n<detail>"
    translate_title: false
    review_lang: "en"
    markdown_theme: "auto"

You can set rich_template to change the template of the rich commit message, and set lang to change the language of the commit message.

Markdown theme

Supported markdown theme:

  • auto: Auto detect markdown theme (default).
  • ascii: ASCII style.
  • dark: Dark theme.
  • dracula: Dracula theme.
  • light: Light theme.
  • tokyo-night: Tokyo Night theme.
  • notty: Notty style, no render.
  • pink: Pink theme.

If you not set markdown_theme, the markdown theme will be auto detected. If you are using light terminal, the markdown theme will be dark, if you are using dark terminal, the markdown theme will be light.

GPTComet is using glamour to render markdown, you can preview the markdown theme in glamour preview.

When verbose is disabled (false), GPTComet runs in silent mode with minimal output, suitable for scripting and automated workflows.

🔦 Supported Keys

You can use gmsg config keys to check supported keys.

📃 Example

Here is an example of how to use GPTComet:

Basic Usage

  1. When you first set your OpenAI KEY by gmsg config set openai.api_key YOUR_API_KEY, it will generate config file at ~/.local/gptcomet/gptcomet.yaml, includes:
provider: "openai"
openai:
  api_base: "https://api.openai.com/v1"
  api_key: "YOUR_API_KEY"
  model: "gpt-6.1-sol"
  retries: 2
output:
  lang: "en"
  1. Run the following command to generate a commit message: gmsg commit
  2. GPTComet will generate a commit message based on the changes made in the code and display it in the console.

Enhanced Error Messages

GPTComet provides helpful error messages with actionable suggestions:

$ gmsg commit

❌ API Key Not Configured

Provider 'openai' requires an API key, but none was found.
