Helps users run multiple concurrent mirrord sessions from a single mirrord-up.yaml (compose-style multi-service local debugging). Use when the user mentions mirrord up, mirrord-up.yaml, mirrord up init, debugging several related microservices together, or managing multiple mirrord sessions' lifecycle in one command.

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 up Skill

## Purpose

Help users create and run **multiple concurrent mirrord sessions** from one config file — think docker compose, but for mirrord — as documented in [Multiple concurrent sessions (mirrord up)](https://metalbear.com/mirrord/docs/using-mirrord/multiple-concurrent-sessions).

Useful when they need to debug **several related microservices** and manage those sessions' lifecycle together.

Each `services` entry is typically a **different** application with its own target, command, and configuration — `mirrord up` is for running several distinct applications together, not for targeting multiple pods of the *same* application. For that (label-based targeting), point users to the **mirrord-operator** or **mirrord-config** skill instead of trying to model it with `mirrord-up.yaml`.

## When to Use This Skill

Trigger on questions like:
- "How do I run multiple mirrord sessions at once?"
- "What is mirrord up / mirrord-up.yaml?"
- "Debug two microservices together with mirrord"
- "`mirrord up init` — how do I generate a config?"
- "How do session keys / HTTP filters work with mirrord up?"
…

How to install

The exact contents, by fingerprint
mdr add metalbear-co/mirrord/mirrord-up@sha256:e837dafc52aaa095

The line at the top of this page pins the label v1.10, 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.
