Who should use the Edit source code workflow?
Teams or solo builders working on development tasks who want a repeatable process instead of one-off tool experiments.
AI Workflow · Development
Practical execution plan for edit source code with clear steps, mapped tools, and delivery-focused outcomes.
Deliverable outcome
The edit is shared with the team and ready for integration after review.
30-90 minutes
Includes setup plus initial result generation
Free to start
You can swap tools by pricing and policy requirements

Use each step output as the input for the next stage
Step map
Instead of relying on a single generic AI model, this pipeline connects specialized tools to maximize quality. First, you'll use Zed 1.0 to you have a clear, bounded understanding of what to change and why, reducing the risk of breaking other parts of the system. Then, you pass the output to GitHub Copilot to the source code now contains the intended modification, with no extraneous changes. Then, you pass the output to Cline to all tests pass and the code meets project style guidelines, confirming the edit is safe and clean. Then, you pass the output to What The Diff to the edit is recorded in version control with a clean, focused diff and a meaningful commit message. Finally, GitLab is used to the edit is shared with the team and ready for integration after review.
Understand and Isolate the Change
You have a clear, bounded understanding of what to change and why, reducing the risk of breaking other parts of the system.
Make the Targeted Edit
The source code now contains the intended modification, with no extraneous changes.
Run Local Tests and Lint
All tests pass and the code meets project style guidelines, confirming the edit is safe and clean.
Review the Diff and Commit
The edit is recorded in version control with a clean, focused diff and a meaningful commit message.
Push and Create Pull Request (Optional)
The edit is shared with the team and ready for integration after review.
Start by reading the relevant code section and any associated tests or documentation to fully understand the current behavior and the desired change. Use a code editor or IDE to open the file and search for the specific function or block that needs modification. This step prevents unintended side effects by clarifying the scope of the edit.
Why Zed 1.0: Zed 1.0 provides a full code editor with syntax highlighting, file search, and autocompletion, directly matching the need for understanding and isolating changes.
Apply the specific code change using your editor, focusing only on the lines or blocks identified in the previous step. Use features like find-and-replace, refactoring tools, or inline editing to modify the code precisely. Avoid cosmetic or unrelated changes to keep the diff clean.
Why GitHub Copilot: GitHub Copilot excels at inline code generation, completion, and refactoring, directly supporting targeted edits in an editor.
Execute the project's test suite and linter to verify that the edit does not break existing functionality or introduce style issues. Use the terminal or IDE-integrated test runner to run unit tests, and run a linter (e.g., ESLint, Pylint) to check for syntax or formatting errors. Fix any failures immediately.
Why Cline: Cline specializes in automated unit and integration testing, directly matching the need to run tests and lint.
Use version control (e.g., Git) to review the diff of your changes, ensuring only the intended modifications are included. Write a clear, concise commit message that describes the 'what' and 'why' of the edit. Stage and commit the changes to your local branch.
Why What The Diff: What The Diff generates automated PR descriptions and summaries, directly supporting diff review and commit preparation.
If working in a collaborative environment, push your branch to the remote repository and open a pull request for review. Include a summary of the change, any related issue numbers, and testing notes. This step is optional for solo projects or direct commits to main.
Why GitLab: GitLab provides a full DevSecOps pipeline with automated code review and pull request management, directly matching the push and PR step.
§ Before you start
Teams or solo builders working on development tasks who want a repeatable process instead of one-off tool experiments.
No. Start with the top pick for each step, then replace tools only if they do not fit your pricing, compliance, or output needs.
Open the mapped task page and compare top options side by side. Prioritize output quality, integration fit, and predictable cost before scaling.
