Testing Expected Results

Run real commands and verify they produce the ACTUAL side effects and outputs you expect - not just "exit code 0." Catches the dangerous cases where commands "succeed" but don't do what they claim.

When to use me

Use this skill when:

• A command returns 0 but you're not sure it actually worked
• You need to verify side effects (files created, data changed, services running)
• Exit code checking gives false confidence
• "It ran without error" isn't enough proof
• Commands have complex side effects across multiple systems
• You're debugging "why did the deploy succeed but the app is down?"
