When you're sleep-deprived and production is on fire, Caro validates every command before it can make things worse. Pattern-based safety that doesn't depend on AI judgement.
What you hire Caro to do
Validate commands against 52+ dangerous patterns before they can destroy production.
Trigger: Running any command on production systems
Generate diagnostic commands instantly during high-pressure incidents.
Trigger: PagerDuty alert at 3 AM
Catch when AI tools suggest dangerous commands with deterministic validation.
Trigger: Using any AI assistant for shell commands
See how Caro handles actual production situations
Context: Production server running out of disk space. You need to free space fast.
Lesson: Caro warns you before wiping logs you might need for post-incident analysis.
Context: Need to clean up old backup files from the database server.
Lesson: Pattern matching catches operations in critical system paths.
Context: Application can't write to its data directory after a botched deployment.
Lesson: Security anti-patterns are caught even when they "fix" the immediate problem.
Context: Evicted pods cluttering the cluster, need to clean them up.
Lesson: Complex k8s commands generated correctly with proper selectors.
Context: API latency issues, need to find which endpoints are slow.
Lesson: Complex pipe chains generated correctly without memorizing ss/awk syntax.
Common alerts and the commands you need

You asked an AI: "Clean up the project directory"
rm -rf ./* Marked as "Safe" You asked: "Restart the service to apply changes"
systemctl restart nginx && systemctl restart postgresql Marked as "Safe" You asked: "Find files modified today" (on macOS)
find . -mtime 0 Marked as "Safe" Same input = same result. No randomness, no "sometimes catches it."
You can see exactly which pattern triggered. Essential for post-incident review.
Regex patterns don't make things up. They match or they don't.
<50ms validation. No API call, no waiting.

No account. No API key. No data collection. Just safer shell commands.
