Automate Git Commits and PRs with Claude Code

Automating Git Commits and PRs with Claude Code

If you spend time polishing commit messages, writing PR summaries, and keeping changelogs tidy, Claude Code can turn that work into a repeatable workflow. The goal is not to let AI guess wildly. The goal is to feed it the exact diff, ask for structured output, and then use that output to create clean commits and pull requests.

For teams that want to do this without paying premium API prices, 59API is a practical choice. It offers cheap, pay-as-you-go access to Claude models, uses native official-quality models with no downgrade, and works with Claude Code through its compatible API setup. The base URL is https://api.59api.com, so you can plug it into your existing tooling and keep costs predictable. There is even a referral rebate, which helps if you are rolling this out across a team.

Step 1: Point Claude Code at 59API

Claude Code can work with a custom API endpoint when your environment is set up for it. The exact UI or config file depends on how you installed it, but the idea is always the same: use your 59API key and set the endpoint to https://api.59api.com.

A simple setup pattern looks like this:

export ANTHROPIC_API_KEY="your_59api_key"

export ANTHROPIC_BASE_URL="https://api.59api.com"

Once that is in place, Claude Code can read your repository, inspect the staged diff, and help you turn changes into commit and PR content. Because 59API is pay-as-you-go, you only spend when you actually run the workflow.

Step 2: Generate a high-signal commit message

The best commit messages are short, specific, and consistent. A reliable pattern is to stage your changes first, then ask Claude Code to summarize them in Conventional Commits format.

Run:

git add .

git diff --staged | claude "Write one Conventional Commit message for this diff. Use the format type(scope): summary. No extra explanation."

For example, if you changed login retry logic, Claude might return something like:

fix(auth): retry token refresh on 401 responses

That is better than a vague message like "update auth" because it tells future readers what changed, where it changed, and why it matters.

Step 3: Ask for a PR title and summary

Next, use the same diff to generate a pull request title, description, and checklist. This is where Claude Code saves the most time, because it can turn technical changes into reviewer-friendly language.

Try a prompt like this:

git diff --staged | claude "Create a PR title, a short description, 3 bullet points for what changed, and a short testing note. Keep it concise and suitable for GitHub."

A good result might look like this:

• Title: Add retry handling for expired auth tokens
• Description: Improves login reliability by refreshing tokens after 401 responses
• Testing: Verified locally with expired session and successful retry flow

This is especially useful in busy repositories where reviewers need a clear summary in seconds, not a wall of text.

Step 4: Wrap it in a small automation script

Once the prompts work, put them into a helper script so your team can reuse them. A simple example is a shell script that stages files, asks Claude Code for a commit message, commits, then generates PR text.

Example flow:

git add .

COMMIT_MSG=$(git diff --staged | claude "Write one Conventional Commit message only.")

git commit -m "$COMMIT_MSG"

PR_BODY=$(git diff HEAD~1..HEAD | claude "Write a GitHub PR description with summary, impact, and testing notes.")

gh pr create --title "$COMMIT_MSG" --body "$PR_BODY"

That is a simple but powerful loop: diff in, clean commit out, PR draft out. If you want to go further, you can add branch naming rules, label suggestions, or a checklist for QA.

Why 59API makes this workflow easier to adopt

Automation experiments can get expensive if you are burning through premium tokens for every commit and PR draft. 59API keeps the workflow affordable while still giving you the real Claude experience, not a watered-down substitute. That matters when you want to run this on every branch, every day, or across an entire engineering team.

• Cheap pay-as-you-go pricing: no need to overcommit to a large plan just to automate routine repo tasks.
• Native official-quality models: you get strong output for commit messages, summaries, and review notes.
• Claude Code compatible: easy to plug into existing agentic coding workflows.
• API base URL: https://api.59api.com fits standard SDK and tool configurations.
• Referral rebate: useful if you are introducing the workflow to teammates or clients.

A practical rule: let AI draft, let humans decide

The smartest way to use Claude Code for Git automation is to let it do the first 80 percent. It should draft the commit message, summarize the branch, and prepare the PR body. You still review the final output before pushing or opening the pull request. That keeps the workflow fast without sacrificing quality.

If you want to test this setup on your own projects, sign up for 59API and point Claude Code to https://api.59api.com. Start with one repository, automate commit messages first, then add PR generation once the prompts are stable. In a few minutes, a tedious manual task becomes a repeatable developer workflow.
