Aider

Aider is a repo-aware coding assistant that works inside a local checkout, applies file edits on disk, and uses your existing git, test, and lint workflow from the terminal. It is built for iterative code changes in real projects, not just one-shot code generation.

• Edit files in an existing repo from natural-language prompts, with repo mapping, read-only context files, and git-aware change tracking.
• Run one-shot coding tasks with --message or keep an interactive session open to refine changes, inspect diffs, and undo or commit results.
• Use lint, test, shell-command, and watch-file workflows so code changes can be checked and corrected inside the same terminal loop.

• Useful when an agent needs a coding-focused tool that can mutate a local repo, reuse project context, and iterate on failures in place.
• The CLI has explicit non-interactive entrypoints for single prompts, but most output is conversational text rather than structured JSON that downstream tools can parse reliably.
• Fits best as a higher-level coding primitive inside a repo workflow, especially when a skill can pin models, approval defaults, and project-specific test or lint commands.

• Real use depends on configuring an LLM provider or local model backend, and some features add optional browser or voice dependencies.
• Default behavior is interactive and git-opinionated, so unattended use usually needs flags like --message, --yes, and explicit test or commit settings.
