description

Generate and validate runnable DTrace scripts for Linux debugging and performance investigations in an agentic coding framework capable of using SKILLs. Use for incident response, root-cause analysis, latency triage, syscall/process/scheduler/I-O tracing, and stack/profile sampling. Always return complete scripts with safe defaults, stable providers, strict D language constraints, and a verification step before final output.

DTrace for Linux

Generate complete D scripts that compile and run cleanly on Linux systems with DTrace.

Output Requirements

• Return a full runnable D program every time.
• Include a shebang for script output: #!/usr/sbin/dtrace -s.
• Prefer predicates for filtering and aggregations for volume control.
• Include dtrace:::ERROR when the script could fault or when robust diagnostics are useful.
• Avoid placeholders, pseudo-code, and partial solutions.

Safety Rules

• Prefer stable providers: syscall, proc, sched, profile, io, pid, usdt, and dtrace.
• Avoid dangerous actions unless explicitly necessary.
• Do not recommend system() unless there is no viable alternative.
• Treat copyout*(), raise(), and system() as destructive.

Forbidden Language Constructs

Never use these constructs in D scripts:

• if
• else
• for
• while
