Individual skill
mirrord-prev-env
Help users create and manage mirrord preview environments — running a modified service as an isolated pod in a shared Kubernetes cluster, scoped by an environment key and HTTP/queue traffic filtering, so teams can validate and review changes against real traffic without affecting live services. Use when a developer wants to run "mirrord preview" ad hoc, share a preview via a link (mirrord-share-ingress), or wire preview environments into CI with the metalbear-co/mirrord-preview GitHub Action (e.g. per-PR previews, least-privilege cluster access).

# Mirrord Preview Environment Skill
## Purpose
Help users create and manage **mirrord preview environments**. A preview environment runs only the *modified* service(s) as isolated pods in a shared cluster, while their dependencies reach the rest of the main cluster through mirrord. Traffic is scoped by an **environment key** and a filter, so a change can be collaborated on, validated, and reviewed against **real traffic without affecting live services**.
This skill covers two modes:
1. **Ad-hoc (developer) mode** — a developer runs the `mirrord preview` CLI (`start` / `status` / `stop`) directly.
2. **CI mode** — the `metalbear-co/mirrord-preview` GitHub Action wires previews into a PR lifecycle (start on open/push, stop on close).
