Connect agents to your IDE via ACP. Swap agents without changing IDEs.

Install and manage Agent Skills. Build your own skill collection.

Part 3 of a series where we take public "token saver" add-ons for coding agents and run the same paired A/B benchmark against each of them. Part 1 was the caveman skill (advertised −65%, measured −8.5%). Part 2 was rtk (advertised −60–90%, measured +7.6%). We ran 80 paired tasks to test the pony…

Does "rtk" reduce Claude Code token usage? Part 2 of a series where we take public “token saving” add-ons for coding agents and run the same paired A/B benchmark against each of them. Part 1 was the caveman skill (advertised −65%, measured −8.5%). TL;DR: rtk advertised saving: 60–90%. Measured…

A paired A/B benchmark of the token-compression skill Caveman on Claude Code, run on SkillsBench: does it actually save tokens, and does it degrade AI agent output quality? Advertised saving: 65%. Measured saving: 8.5%. Output-token saving on real agentic tasks, with the skill forcibly activat…

Born out of a deep partnership between JetBrains and GitHub, this integration makes Copilot native in the agent picker and delivers a more stable agent experience directly in the IDE you already use every day. From ACP Registry to native experience Copilot was previously accessible via the…

443 developers applied. 39 projects shipped. Here's a deepdive on the finalists and their projects presented at the JetBrains X Codex Hackathon in San Francisco.

Junie CLI meets JetBrains IDE: shared context, semantic refactoring, smart search, and build configs — your terminal agent just got a whole lot smarter.

Smarter AI-assisted workflows; new experimental symbol-based language modeling engine, that boosts performance; stable remote development support, and more.

Cursor is now available as an AI agent inside JetBrains IDEs through the Agent Client Protocol.

Together with Zed, we've launched the official ACP Registry: a directory of AI coding agents, integrated directly into JetBrains IDEs.
