Create a new debug session for a specific programming language. Returns a session ID to use with other tools.

Start debugging a script file. The program will run until it hits a breakpoint or completes.

Terminate a debug session and clean up resources

List all active debug sessions

Set a breakpoint at a specific line in a source file. Use dumpFile to create a tracepoint that dumps variables to a file and auto-continues.

Get collected traces from tracepoints. Traces are stored in session state and can be queried with filtering and pagination.

Clear all collected traces from the session

Remove a breakpoint from a source file

List all breakpoints in the session

Continue execution until the next breakpoint or program end. Use waitForBreakpoint to block until a breakpoint is hit and return variables. Use collectHits to run through multiple breakpoint hits, collecting variables at each, then return all traces.

Pause program execution

Step into the next function call

Step over to the next line (execute function calls without entering)

Step out of the current function

Step through code N times, collecting variables at each step. Returns all traces or writes to a file. Useful for tracing execution flow.

Get the current call stack

Get variables in the current scope

Expand a complex variable to see its properties/children

Evaluate an expression in the current context

Get source code around the current execution point

Get all threads in the debugged program
