Coding Agents
Tier 4
Aider
Summary
The benchmark terminal pair-programming agent. Its two signature patterns: a tree-sitter powered repo map that gives the model compressed, ranked codebase context, and diff-based edit formats that make model edits reliable and reviewable.
Key Takeaways
- Repo map: compressed, ranked codebase context beats raw file dumps
- Diff-based edits are more reliable than whole-file rewrites
- Git-native workflow: every agent change is a commit you can undo
