Explainable suspicion scoring beats age-based cleanup tools like kubeclean.

Strengths

•Nine independent signals with weighted scoring instead of simple age thresholds.
•--explain flag shows exact scoring breakdown for each flagged pod.
•CI-friendly exit codes enable automated cluster hygiene in pipelines.

Weaknesses

•No auto-cleanup mode means manual intervention still required after detection.
•Read-only design is safe but limits utility compared to action-taking tools.

Post Description

Hi HN,

Clusters tend to accumulate garbage: debug pods, failed jobs, test workloads that nobody cleans up. I built Columbo, a CLI that tries to detect these by assigning a suspicion score to each pod.

Would love feedback.
