analyze-runtime SKILL.md skillB

analyze-runtime from mendixlabs/mxcli is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add mendixlabs/mxcli/analyze-runtime@git:20261010.50fe33a

Pins git:20261010.50fe33a in mdr.lock. Pin the fingerprint instead.

Find out what a running Mendix app actually does — logs, Prometheus metrics, OpenTelemetry traces and the model catalog, joined across sources. Use when profiling a slow page or microflow, finding what hits the database, chasing an error that shows only a generic dialog, or correlating runtime cost with model shape.

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.

`sed -n '<from>,<to>p' SKILL.md` one section rather than reading the file;
`./mxcli syntax <topic>` answers *how do I write this* for a fraction of either.

# Analyze an App's Runtime Behavior — Logs, Metrics, Traces, Catalog

## Overview

When you need to understand what an app *actually does* at runtime — why a page is
slow, which microflow dominates cost, what hits the database, whether an error is
network or logic — the signals live in four places. This skill is the procedure for
collecting them and, crucially, **joining them**, because the useful questions cross
sources that no single tool answers alone.

How to install

The exact contents, by fingerprint
mdr add mendixlabs/mxcli/analyze-runtime@sha256:81d71e31f71addf8

The line at the top of this page pins the label git:20261010.50fe33a, 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.
