Coding Agents

AI agents that write, review, and ship code. From CLI tools to IDE integrations — the new wave of AI-powered software development.

The coding agent revolution

Coding agents are AI systems purpose-built for software development. Unlike simple autocomplete or chat-based code generation, coding agents can understand codebases, plan changes across multiple files, execute commands, run tests, and iterate on their own output.

They represent the most mature category of AI agents — because code is the perfect proving ground. It’s structured, testable, and has clear success criteria.

What makes a coding agent

A true coding agent goes beyond code generation:

  • Codebase understanding — reads and navigates existing code, understands project structure
  • Multi-file editing — plans and executes changes across multiple files
  • Tool use — runs shell commands, tests, linters, build tools
  • Iterative refinement — fixes errors based on feedback loops
  • Context management — handles large codebases without losing track

The current landscape

CLI-first agents

Terminal-native agents that work directly in your development workflow.

Codex CLI (OpenAI) — Agentic coding in the terminal with sandboxed execution Claude Code (Anthropic) — Deep codebase understanding with extended thinking Gemini CLI (Google) — Google’s entry into terminal-based coding agents Aider — Open source pair programming in the terminal

IDE-integrated agents

Agents that work inside your editor, blending AI with your existing workflow.

Continue — Open source AI code assistant for VS Code and JetBrains Cursor — AI-first code editor (partially open source) Copilot — GitHub’s AI pair programmer (closed source, included for comparison)

Specialized code agents

SWE-Agent — Automated software engineering for issue resolution OpenHands — Open platform for software development agents Devon — Open source pair programmer focused on real-world tasks

What to watch

  • CLI agents becoming the default interface for experienced developers
  • Multi-agent code review pipelines
  • Agents that can manage entire repositories, not just files
  • Integration with CI/CD for automated issue-to-PR workflows
