Tell your agent to use IntelliJ IDEA functionality using the IntelliJ MCP server. If you're also interested, you can see the supported tools here: www.jetbrains.com/help/idea/mc... "better quality, fewer tokens burnt" - Thanks @toomuchcoding.com, I couldn't have said it better myself!

https://www.jetbrains.com/help/idea/mcp-server.html#supported-tools this is insanely fantastic
delegating work to intellij's mcp server IMO is sth fabulous

In the age of AI tests are more important than ever, they are the guardrails for LLMs. Contract tests are essential for you to guard integrations. Check stubborn.sh as an implementation of contract tests with Spring Cloud Contract (works for npm too!)
