jetbrains-debugger

What problem does it solve?

It helps you debug runtime behavior in JetBrains IDEs when static code reading and guesswork can’t explain wrong values, unexpected control flow, or failing tests.

Core Features & Use Cases

• Breakpoints and tracepoints: Set line breakpoints, conditional pauses, and log-only tracepoints to pinpoint where execution diverges.
• Execution control and stepping: Start/stop debug sessions and drive step over/into/out or run-to-line to move through code precisely.
• Runtime inspection and evaluation: Inspect variables/stack/source context and evaluate expressions in the current debug frame to validate hypotheses.
• Multi-session debugging support: Manage multiple concurrent sessions and retrieve rich state in a single call.
• Safety-aware expression handling: Works within IDE safety filters (blocklists / read-only modes) and provides guidance for safer inspection when evaluation is restricted.

Quick Start

Use the jetbrains-debugger skill to set breakpoints, start the appropriate debug configuration, wait for the pause, then inspect variables and step through execution until you find the root cause.
