Simple Commit Template
The classic Git commit message: one short line that summarizes the change, a blank line, and an optional body that explains what changed and why. It is the format Git's own documentation recommends and the one most tools display best.
- You want a lightweight default that works in any repository.
- The change is small enough that a summary and a sentence or two of context say everything.
- Your team has no formal convention yet.
Template
Replace each <placeholder> by hand when you write a commit.
Lines starting with # are guidance that Git removes in its default cleanup mode.
Completed example
A small feature in a desktop app.
Add keyboard shortcut for toggling the sidebar Switching between the file list and the diff view required a mouse click every time. The sidebar can now be toggled with Ctrl+Shift+B, and the shortcut is listed in the View menu.
Guidance
Rules
- Start with a single summary line of about 50 characters or less; Git's documentation recommends this length.
- Separate the subject from the body with one blank line. Many tools treat everything up to the first blank line as the title.
- Write the subject in imperative mood, as if completing the sentence "If applied, this commit will…".
- Don't end the subject with a period.
- Wrap body lines at around 72 characters so they read well in terminals and email.
- Use the body to explain what and why; the diff already shows how.
Optional fields
- Body
- Skip it when the subject says everything. Add it whenever a reviewer would ask "why?"
Common mistakes
- Vague subjects such as "Fix stuff", "Updates", or "WIP".
- Describing the files you touched instead of the effect of the change.
- Cramming several unrelated changes into one commit and one subject.
- Leaving the placeholder text in the message.
How it relates to other templates
Every other template in this library builds on this structure. If your team later adopts types and scopes, move to Conventional Commits; if reviewers keep asking for context, try the Detailed Change template.
Use this template
Use in Tower
Tower for Mac
- Open Tower's Settings and select the Templates tab.
- Create a new template and enter the subject and body below. You can also download the template file and import it from the same tab. After importing, remove the lines that start with
#. They're guidance for Git's editor. - To use it by default, set it as the global Git value in the Templates tab, or pick it as the default commit template in a repository's settings.
- When you write a commit, click the Commit template button below the description field, or type t: or / in the subject field to choose a template.
More details: Commit Templates in the Tower for Mac documentation.
Tower for Windows
- Open Tower's Preferences and select the Templates tab.
- Click + to create a new template and enter the subject and body below.
- To use it by default, set it as the global default template, or pick it as the default in a repository's settings.
- When you write a commit, click the Commit template button in the commit composer, or type t: or / in the subject field to choose a template.

Download gitmessage-simple.txt
The commands below assume the file is in your Downloads folder.
macOS and Linux (Terminal)
Try it once
Run this in a repository with staged changes. Git opens your editor with the template filled in:
git commit --template ~/Downloads/gitmessage-simple.txtMake it the default for one repository
From the repository's root folder, save the file as .gitmessage and point Git to it:
mv ~/Downloads/gitmessage-simple.txt .gitmessage
git config commit.template .gitmessageMake it your global default
Save the file in your home folder and use it for every repository without its own setting:
mv ~/Downloads/gitmessage-simple.txt ~/.gitmessage
git config --global commit.template "~/.gitmessage"Windows (PowerShell)
Try it once
Run this in a repository with staged changes. Git opens your editor with the template filled in:
git commit --template "$HOME\Downloads\gitmessage-simple.txt"Make it the default for one repository
From the repository's root folder, save the file as .gitmessage and point Git to it:
Move-Item "$HOME\Downloads\gitmessage-simple.txt" .gitmessage
git config commit.template .gitmessageMake it your global default
Save the file in your home folder and use it for every repository without its own setting:
Move-Item "$HOME\Downloads\gitmessage-simple.txt" "$HOME\.gitmessage"
git config --global commit.template "~/.gitmessage"Share it with your team
Commit .gitmessage to the repository so everyone has the same file. Sharing the file does not configure anyone's Git: Git never applies settings from a repository automatically, so each teammate runs this once in their clone:
git config commit.template .gitmessageInspect, change, or remove the default
# Show the configured template and where it's set
git config --show-origin --get commit.template
# Point to a different file
git config commit.template path/to/other-template.txt
# Remove the repository or global setting
git config --unset commit.template
git config --global --unset commit.template- Templates guide, hooks enforce. A template only pre-fills the editor. To reject messages that don't follow a convention, add a commit-msg hook.
- Only the editor uses templates.
git commit -mandgit commit -Fbypass the template. - Unchanged templates abort the commit. If you save without editing the template, Git stops with "you did not edit the message".
- Comment removal depends on cleanup. Git strips
#lines under its defaultstripcleanup mode. With--cleanup=verbatim,--cleanup=whitespace, or a matchingcommit.cleanupsetting, they stay in the message. If you changedcore.commentChar,#lines aren't treated as comments. - Other commands write their own messages.

Use with coding agents
This skill teaches your coding agent to draft commit messages in the Simple Commit format. It uses the library version of the template. Edits you make in the editor above aren't included.
- Follows your repository's instructions and your explicit requests first.
- Reads the staged changes and keeps unstaged work out of the message.
- Never invents motivation, issue numbers, benchmarks, or test results. It leaves placeholders and asks instead.
- Flags breaking changes and unrelated changes that should be split.
- Drafts only. It won't stage, commit, or push unless you ask it to.
Download skill commit-message-simple-v1.0.0.zip · Agent Skills format · MIT-0 license
Contains commit-message-simple/SKILL.md with the instructions, references/REFERENCE.md with the rules and a completed example, and assets/template.txt.
Install in Claude Code
- Unzip the download. It contains a single folder named after the skill.
- Move that folder to
.claude/skills/in your repository to share it with your team, or to~/.claude/skills/to use it in all your projects. - Start a new Claude Code session and ask it to draft a commit message. You can also invoke the skill directly with
/commit-message-simple.
See the Claude Code skills documentation for details.
Other agents
The package uses the open Agent Skills format, but we've only tested the agents listed above. For any other agent, check its documentation for skill support, or add the instructions below to its configuration file, such as AGENTS.md.
Copy the instructions
Add these instructions to your agent's configuration or your repository's AGENTS.md:
## Commit messages
Use the Simple Commit structure below.
```text
<Summarize the change in imperative mood, about 50 characters>
<Optional: explain what changed and why. Wrap lines at 72 characters.>
```
Rules:
- Start with a single summary line of about 50 characters or less; Git's documentation recommends this length.
- Separate the subject from the body with one blank line. Many tools treat everything up to the first blank line as the title.
- Write the subject in imperative mood, as if completing the sentence "If applied, this commit will…".
- Don't end the subject with a period.
- Wrap body lines at around 72 characters so they read well in terminals and email.
- Use the body to explain what and why; the diff already shows how.
- Summarize the single most important effect of the staged changes in the subject.
- Only add a body when the diff or the user's request provides a reason for the change; otherwise leave it out rather than guessing.
When writing a commit message:
- Base it on the staged changes (`git diff --staged`). Don't describe unstaged work as part of the commit.
- If the staged changes are unrelated to each other, suggest splitting the commit.
- Never invent motivation, issue identifiers, benchmark numbers, or test results. Keep a `<placeholder>` and ask instead.
- Call out breaking changes and include migration information supported by the changes.
- Draft the message for review. Don't stage, commit, or push unless explicitly asked.
