Prerequisites and connection details for attaching to a live Python process with PyFlightProfiler. Read this skill first before using any other PyFlightProfiler command (watch, trace, stack, perf, etc.).

원문 언어: 영어

flight-profiler-getglobal

Inspect Python module global field or class static field value in a running Python process. Use this for safe, read-only inspection of global variables, configuration objects, or class-level state.

원문 언어: 영어

flight-profiler-module

Translate a file path to its Python module name in a running Python process. Use this when you know a file path but need the module name for commands like watch, trace, or reload.

원문 언어: 영어

flight-profiler-reload

Hot-reload a Python function implementation from the latest file content without restarting the process. Use this to apply code fixes live after identifying a bug with watch/trace.

원문 언어: 영어

flight-profiler-stack

Inspect stack frames of a running Python process including thread stacks, native C-level frames, and async coroutine stacks. Use this to see what each thread is currently doing and diagnose hangs, deadlocks, or stuck async tasks.

원문 언어: 영어

flight-profiler-trace

Trace execution time of Python method invocations in a live process with call stack visualization. Use this to see a hierarchical call tree showing which sub-calls are slow and where time is spent within a function.

flight-profiler-vmtool

Inspect live Python class instances in a running process — find all instances of a class, examine their attributes/state, or invoke methods on them. Also supports forcing GC. Use this when you need to probe object-level runtime state beyond what…

flight-profiler-watch

Display input/output args, return object and cost time of a Python method invocation in a live process. Use this to observe function behavior at runtime — see what arguments go in, what comes back, and how long it takes. This is the most frequently used…
