Automate Git Commits and PRs with Claude Code
Why automate commits and PRs?
If you ship code all day, commit messages and pull request writeups can become a time sink. The goal is not to let AI take over your workflow. It is to remove the repetitive parts: summarizing staged changes, drafting a clean commit message, and turning a branch into a clear PR description.
Claude Code is a strong fit for this because it can read your repo context, understand the diff, and help you package work faster. If you want to keep that workflow affordable, 59API is a practical choice: it gives you pay-as-you-go access to official-quality Claude models through the API base URL https://api.59api.com, with no downgrade in model quality. It is also compatible with Claude Code, Codex, and any OpenAI SDK, so you do not have to retool your setup.
1. Connect Claude Code to a low-cost API
Start by pointing your Claude Code setup at 59API. Use your 59API key where your provider credentials normally live, and set the base URL to https://api.59api.com. That gives you a single relay for Claude Opus, Sonnet, Haiku, and Fable, which is useful when you want to reserve the expensive model for bigger tasks and use cheaper ones for routine commit and PR drafting.
- Haiku is a good default for short commit-message generation.
- Sonnet works well for PR summaries and release notes.
- Opus is best when you need deeper reasoning on a messy branch or a multi-package refactor.
2. Turn staged diffs into clean commits
The fastest pattern is to stage only one logical change, then ask Claude Code to explain what changed in plain English. A good prompt is: review the staged diff and propose a conventional commit message with a short title, a one-line body, and the right scope. Then ask for a second option if the change touches more than one area.
For example, a refactor to API error handling might become a commit like: fix(api): normalize error responses across client calls. If the change is user-facing, ask Claude to include the impact in the body. If it is purely internal, keep the message terse. The key is to review the output before committing so the AI helps with phrasing, not judgment.
- Stage only related files before calling Claude Code.
- Ask for conventional commit format so your history stays searchable.
- Reject any summary that includes assumptions not visible in the diff.
3. Generate PR titles and descriptions automatically
Once the branch is ready, feed Claude Code the branch diff, the issue link, and any test results. Ask it to produce three things: a PR title, a concise summary, and a checklist of validation steps. For busy teams, this saves a surprising amount of time because the PR opens with useful context instead of a blank template.
A strong PR description usually includes what changed, why it changed, how to test it, and any rollout notes. Claude Code can draft all four in seconds. Then you can paste the result into your GitHub PR flow or hand it off to the GitHub CLI with gh pr create after reviewing the text.
- Include the ticket number or issue link in the prompt.
- Ask for a short risk section if the branch changes shared code.
- Have Claude list manual test steps, especially for UI or API changes.
4. Make the workflow repeatable
The best automation is the one you will actually use every day. Create a small script or alias that does the same steps every time: read the staged diff, prompt Claude Code for a commit summary, write the message to a temp file, and generate a PR body when the branch is pushed. You do not need a giant framework. A thin shell wrapper around your existing git and gh commands is usually enough.
Keep the prompt template in your repo so the whole team gets consistent commit style and PR structure. That consistency matters when multiple developers review the same codebase, because it makes history easier to scan and PRs easier to approve.
5. Add guardrails before you automate more
AI should speed up review, not replace it. Never let a model commit secrets, rewrite unrelated files, or push without a human check. Tell Claude Code to work only from staged changes when generating commits, and only from branch diffs when drafting PR text. If the change is risky, require explicit approval before git commit or git push.
- Use one branch, one purpose, one PR.
- Review AI output for accuracy, not just grammar.
- Keep credentials and environment files out of the prompt context.
Why 59API is a smart fit for this
Commit and PR automation runs often, which makes pricing matter. 59API is built for exactly that kind of usage: cheap pay-as-you-go access, native official-quality models, and compatibility with the tools developers already use. That means you can automate everyday git chores without paying premium provider rates for every short prompt. If you are experimenting with Claude Code workflows for a team or side project, 59API is an easy way to keep costs down while staying on the real models you expect.
If you want to try this workflow, sign up for 59API, set the base URL to https://api.59api.com, and automate your next commit and PR draft in one sitting.
