Aider

Context

Uses explicitly added files, a token-budgeted repository map of important symbols, recent Git history, command output, and optional read-only material.

Actions

Edits files, commits through Git, runs user-selected commands, and invokes configured lint and test workflows.

Execution

Runs locally in the repository and uses the machine's shell, Git installation, language tools, and model provider connection.

Memory & rules

Repository context comes from files, the repo map, Git, and configuration. It is intentionally lighter than products with large persistent rule or memory systems.

Permissions

The user controls which files enter the chat and which commands are run. Local shell and provider credentials inherit the user's operating-system permissions.

Verification

Can automatically lint edited files and run a configured test command, then attempt repairs when checks fail. Git commits and `/undo` provide reviewable checkpoints.

Best for

• Lightweight terminal pair programming
• Git-native, reviewable edits
• Projects with clear lint and test commands

Limitations

• Editorial judgment: broad personal-assistant or messaging workflows
• Editorial judgment: delegated cloud work that must continue after the local process ends
