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.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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). ## When to Use This Skill Trigger on questions like: - "How do I run a mirrord preview environment?" - "Set up per-PR preview environments with mirrord" - "How do I use the mirrord-preview GitHub Action?" - "`mirrord preview start` — what config and flags do I need?" - "How do I route only my traffic to the preview pod?" - "How do I check / stop a preview session?" ## Security (must follow) …

How to install
mdr add metalbear-co/skills/mirrord-prev-env@sha256:3446c3009b6f7863The line at the top of this page pins the label v2.9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
