# Coding Agents

> **TL;DR.** Coding Agents is the category name for AI developer tools that act on code autonomously — reading a repo, planning a change, editing files, running tests, and opening pull requests — rather than suggesting inline tokens like 2021-era copilots.

## Definition

Coding Agents is the category name for AI developer tools that act on code autonomously — reading a repo, planning a change, editing files, running tests, and opening pull requests — rather than suggesting inline tokens like 2021-era copilots. It spans terminal agents ([Claude Code](https://github.com/anthropics/claude-code), [OpenAI Codex CLI](https://github.com/openai/codex), Aider, OpenCode), IDE-embedded agents (Cursor, Windsurf, Google Antigravity), and async background agents (GitHub Copilot coding agent, Jules, Devin).

The label crystallized during 2025: GitHub launched the ['Copilot coding agent'](https://github.blog/changelog/2025-05-19-github-copilot-coding-agent-in-public-preview/) in public preview on May 19, 2025, Google unveiled Jules as an 'asynchronous coding agent' the same day, and OpenAI's Codex CLI (April 2025) was described as a 'lightweight coding agent.' By early 2026 'agent' had replaced 'copilot' as the category vocabulary.

## Example

A developer installs Claude Code or Codex CLI, writes an AGENTS.md describing the repo's conventions, and assigns a GitHub issue to the agent. It reads the codebase, plans, edits, runs tests, iterates, and opens a PR. Teams shipping this — Cursor Agent, GitHub Copilot coding agent, Jules, Devin — report 3M+ weekly active Codex users (Feb 2026, Pragmatic Engineer) and 46% 'most loved' for Claude Code.

## Analogy

The shift from spell-check to a junior engineer you can assign tickets to — same keyboard, completely different relationship.

## Why it's emerging now

Three simultaneous May 19, 2025 launches (GitHub Copilot coding agent, Google Jules, and OpenAI Codex CLI) ended the naming debate. By early 2026 Apple shipped 'agentic coding' in Xcode 26.3, AGENTS.md standardized agent config, and 50+ products in a single April week self-identified as coding agents — signaling category lock-in.
