Creates and manages RudderStack transformations and libraries with local testing. Use when creating, editing, or managing RudderStack transformations and transformation libraries using the Rudder CLI.
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
# RudderStack Transformations with Rudder CLI
## Overview
RudderStack transformations allow real-time event manipulation using JavaScript or Python. Libraries provide reusable code shared across transformations. Both are managed as code using YAML specs and the Rudder CLI.
## Recommended Workflow
Follow this loop for every change — authoring a new transformation or library, or editing existing code. Testing locally with fixtures is the key step that distinguishes transformations work from other CLI workflows.

How to install
mdr add rudderlabs/rudder-agent-skills/rudder-transformations@sha256:b2793c3328f0ed0cThe line at the top of this page pins the label git:20261027.bb53b9e, 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.
