JetBrains Junie graduates with real debugger access

JetBrains pushed Junie out of beta and rebuilt it on the Agent Communication Protocol. The headline trick is agentic debugging: the agent drives the actual IDE debugger instead of guessing, and you can now point it at a whole directory of guideline files.

Junie is JetBrains' coding agent across IntelliJ, WebStorm, PyCharm and the rest of the family, plus a standalone CLI for terminal and CI work. The GA release rebuilt the IDE integration on ACP and hardened the bits teams said they needed before trusting an agent on production code.

Agentic debugging that uses the real IDE debugger, not heuristics
Agent Skills: reusable, task-shaped extensions for specialized workflows
Guideline directories so you can split rules across many .md files
Model support spanning OpenAI, Anthropic, Google and Grok
