Does this skill modify my workspace or source code?

No, the JDB Debugger skill is designed to interact with the running JVM and compiled bytecode. It explicitly avoids creating temporary files or wrapper scripts in your project workspace.

How do I attach to a running Spring Boot application?

Ensure your Spring Boot application is started with JDWP flags (e.g., -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=*:5005) and use the jdb-attach script with the corresponding port.

Can I use this skill on Windows?

Yes, but it requires Windows Subsystem for Linux (WSL) to execute the Bash-based skill scripts and interact with the Java environment correctly.

Do I need a specific JDK version to use this skill?

This skill requires a standard JDK installation that includes the 'jdb' command. It is compatible with any Java application running with JDWP (Java Debug Wire Protocol) enabled.

What is the benefit of the 'auto-inspect' mode?

Auto-inspect mode allows Claude to automatically run a series of diagnostic commands (where, locals, cont) for a set number of cycles, making it easier to capture the state of an application during a crash or loop.

开发者工具

Debugs Java applications in real-time by interacting with the Java Debugger (JDB) CLI to set breakpoints, inspect variables, and diagnose JVM issues.

The JDB Debugger skill empowers Claude to perform live debugging of Java applications directly within the terminal. It provides a standardized interface for attaching to running JVMs or launching new processes under the JDK's built-in command-line debugger. By automating complex JDB interactions through specialized scripts, it allows for seamless breakpoint management, stack trace analysis, and variable inspection without manual file creation, making it an essential tool for diagnosing production issues, deadlocks, and runtime exceptions in Java environments.

主要功能

01Advanced diagnostics for thread analysis and automated deadlock detection.

02In-depth state inspection including local variables, fields, and object dumps.

0337 GitHub stars

04Real-time interaction with running JVMs via JDWP attachment or direct launch.

05Automated breakpoint management and interactive code stepping (Into/Over/Up).

06Batch mode execution with automated inspection cycles and timeout protection.

使用场景

01Inspecting the internal state of running Spring Boot or Gradle applications without a GUI-based IDE.

02Diagnosing intermittent NullPointerExceptions or runtime crashes in production-like environments.

03Analyzing complex multi-threaded deadlocks using real-time thread dumps and monitor states.
