I'll analyze this and get back to you.

@claude can you write a small go tool that loads a go execution trace and, given a time offset in the trace, lists the goroutines at that time that are runnable?

I've created a Go tool to analyze execution traces and list runnable goroutines at specific time offsets.

Todo List

• Read repository guidelines (CLAUDE.md) - No CLAUDE.md found
• Research Go trace analysis APIs
• Design the tool structure and CLI interface
• Implement trace loading functionality
• Implement time offset parsing and goroutine filtering
• Test the implementation - Basic validation complete
• Commit changes and provide PR link

Implementation Complete ✅

Created a tool in /tracerunnable/ that:

• Takes a trace file and time offset as command line arguments
• Parses Go execution traces using the trace package
• Tracks goroutine state transitions up to the specified time
• Lists all goroutines in runnable state at that moment

Usage

cd tracerunnable
go run main.go -trace trace.out -time 1.5s

Files Created

• tracerunnable/main.go - Main implementation
• tracerunnable/go.mod - Go module file
• tracerunnable/README.md - Documentation with examples
