Valid JSON/YAML output across clusters; existing tools (kubectl-foreach, kubectl-allctx) don't.

Strengths

•JSON/YAML output with context metadata enables jq/yq chaining for complex multi-cluster queries.
•Honest limitations: read-only ops only, v0.x stability caveat, clear comparison to prior art.
•Parallel batching (default 25) with configurable size balances throughput and cluster load.

Weaknesses

•Incremental improvement over existing tools (kubectl-foreach, kubectl-allctx); main value is output format.
•Read-only scope intentionally limited; write operations require separate tooling.

Post Description

I built this to help look at all the Kubernetes clusters my team manages, to help with planning, troubleshooting, validating acceptance criteria on a ticket, etc.

I could probably have used a monitoring tool but 1) sometimes monitoring tools are split up by cluster/environment anyway, and 2) I like the kubectl interface with JSON and YAML output.

Curious what people think and open to feedback!
