AI Coding Agents

A class of AI agents that autonomously perform software development tasks — code generation, multi-file editing, test execution, bug fixing, and pull request creation. Since 2024, the category has expanded rapidly with tools including Claude Code (Anthropic), Copilot (Microsoft/GitHub), Devin (Cognition AI), Cursor, and Windsurf, converging into three distinct tiers: CLI agents, IDE-integrated agents, and cloud engineering agents.

Competitive differentiation has shifted away from underlying model capability toward memory systems (spec files like CLAUDE.md), tool ecosystems, and multi-agent orchestration pipelines — driving demand for context engineering as a core developer skill.
