Choosing Aider for terminal and Git workflows

Start with a focused file set

Select a task whose relevant files you can identify, such as an input validator and its tests. Ask for one boundary-case correction without changing the public behavior elsewhere. Before adding a large directory, identify the missing evidence. A controlled file set makes an unexpected change easier to notice and a failed attempt easier to diagnose.

Make version control the review surface

Use Git as the review surface, not the agent’s narration as the final authority. Inspect the starting worktree and preserve existing work before an experiment. A reviewer should be able to distinguish human changes from the new task’s changes and inspect both the diff and the verification output before accepting the result.

Separate design discussion from editing

Aider offers several chat modes. Resolve an ambiguous requirement before requesting file changes, and keep the agreed design in the issue. Two-stage design and editing can involve additional model calls; measure whether the clearer result saves enough rework to justify that extra step on your own tasks.

Reconcile model-cost estimates

Model access is separate from the client. Unknown model metadata can make displayed context or cost estimates unsuitable for budgeting. Compare session estimates with the provider’s actual usage record and include failed attempts. A client with no separate license charge can still generate substantial inference spending.

Before changing the model route, review file scope and expected behavior. More allowance may simply fund repeated attempts at an underspecified task. Record provider cost and human review time per accepted change and identify the needed capacity or model before justifying another agreement.

Example: changing a CSV converter

Use a CSV conversion function and its tests to add one column. Specify output order, missing values and values containing text, with concrete expected output. Review a first patch limited to that addition; defer unrelated cleanup or library changes. This makes the relationship between the issue and the Git diff visible and gives the next maintainer a small, understandable change to inspect.

For a hypothetical CSV change containing unrelated cleanup, reject it and retry with only the required column addition. Verify that pre-existing human work is intact and the second diff is independently readable. Rehearse an unsuccessful attempt as well as a successful one so recovery has been demonstrated rather than merely assumed.

A fit for terminal-oriented reviewers

Aider is a useful candidate when your reviewer is comfortable with commands, files and Git. An integrated environment may be more convenient if you do not want to manage the development setup yourself. Choose based on your ability to understand and recover from a failed change, not solely on whether the interface looks simpler.

Keep startup, tests, design decisions and accepted diffs in the repository. Check that a maintainer can understand the project without the original model session. This makes later provider changes manageable. On retirement, distinguish the client from inference billing and review unused credentials and connections separately.
