Today, we’re rolling out ACP Agent Registry in JetBrains IDEs. Instead of manually setting up coding agents one by one, you can now browse what’s available and install them with a single click. Try different agents, see what’s best for your workflow, and switch as needed. https://jb.gg/RegistryACP

What happens when your AI agent runs out of context? In Part 5 of our blog series, we dig into context explosion. Bigger windows aren't the answer – smarter compression is. We show how to help agents decide what to remember, what to discard, and how to keep moving forward. Read more: jb.gg/eagynp

Sneak peek 👀 ACP Agent Registry is coming to JetBrains IDEs soon as part of our ongoing ACP (Agent Client Protocol) collaboration with @zed.dev. Install the agent you want in the IDE you love.
