validation-microflows skillA
validation-microflows is agent-read markdown (skill) from mendixlabs/mxcli: Validation microflows for new/edit pages — attribute checks, feedback messages, and conditional validation chains. Use when a form needs input validation with messages shown against the fields..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Validation Microflows Skill This skill provides guidance for creating validation microflows in MDL that validate user input on NewEdit pages and provide feedback to users. ## When to Use This Skill Use this skill when: - Creating validation logic for NewEdit pages - Implementing attribute validation with feedback messages - Building conditional validation chains - Creating action microflows that call validation microflows > **Nanoflow validation:** The same patterns apply to nanoflows (`create nanoflow` instead of `create microflow`). Use nanoflows for client-side validation when server roundtrips are unnecessary — validation feedback renders instantly without a network call. ## The Validation Pattern Mendix validation follows a two-microflow pattern: 1. **VAL_Entity_Action** - The validation microflow that: - Takes an entity object as parameter - Validates each required field - Shows validation feedback on invalid fields - Returns a Boolean indicating overall validity 2. **ACT_Entity_Action** - The action microflow that: - Calls the validation microflow - Only proceeds with save/commit if validation passes - Closes the page on success ## MDL Syntax …

How to install
mdr add mendixlabs/mxcli/validation-microflows@git:20260922.4954f84mdr add mendixlabs/mxcli/validation-microflows@sha256:f48447ee51966cc0Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
