Individual skill
reproduction-trace-instrumenter
Instruments programs to capture execution traces specifically for reproducing reported bugs, enabling consistent replay and diagnosis of failures. Use this skill when you need to reproduce a bug, capture execution traces for debugging, instrument code to record program behavior, generate replay scripts for bug reproduction, diagnose hard-to-reproduce failures, or perform deterministic replay of program execution. Triggers when users ask to instrument code for tracing, capture execution traces, reproduce bugs, generate replay scripts, or enable deterministic debugging.

# Reproduction Trace Instrumenter
## Overview
This skill instruments source code to capture detailed execution traces for bug reproduction. It records function calls, variable values, control flow, and program state, then generates replay scripts to deterministically reproduce the bug for diagnosis.
## Workflow
### 1. Identify the Bug Context
Before instrumentation, understand:
- What is the bug or failure being investigated?
- Which code paths are likely involved?
- What inputs trigger the bug?
