STATE OF CLI CODING AGENTS, MID-2026

Summary from the TLDR AI newsletter

Claude Code, Codex CLI, and Omp are close enough in result quality that it wouldn't make sense to rank them. They can all read a serious repository, form a plan, edit across files, run checks, recover from failures, and land production-shaped patches. However, they differ in task clarity, repository hygiene, permissions, and whether the harness exposes the right tool at the right moment. OpenCode produces lower-quality results, but it tries the hardest to be good with every model.
