Debugger

Domain: debugger

CDP-based debugging domain covering breakpoints, stepping, call stacks, watches, and debugger sessions.

Profiles

• workflow
• full

Typical scenarios

• Set and hit breakpoints
• Evaluate expressions in frames
• Save and restore debugger sessions

Common combinations

• debugger + hooks
• debugger + antidebug

Representative tools

• debugger_enable — Enable the debugger (must be called before setting breakpoints)
• debugger_disable — Disable the debugger and clear all breakpoints
• debugger_pause — Pause execution at the next statement
• debugger_resume — Resume execution (continue)
• debugger_step_into — Step into the next function call
• debugger_step_over — Step over the next function call
• debugger_step_out — Step out of the current function
• breakpoint_set — Set a breakpoint at a specific location. Supports URL-based and scriptId-based breakpoints with optional conditions.
• breakpoint_remove — Remove a breakpoint by its ID
• breakpoint_list — List all active breakpoints
