write-nanoflows skillA

write-nanoflows is agent-read markdown (skill) from mendixlabs/mxcli: Nanoflow syntax in MDL — shared with microflows, but client-side and restricted. Use before writing any CREATE NANOFLOW, when a nanoflow validation error needs explaining, or when deciding between a nanoflow and a microflow..

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

# Mendix Nanoflow Skill

This skill provides guidance for writing Mendix nanoflows in MDL syntax. Nanoflows share syntax with microflows but execute client-side with restricted capabilities.

## When to Use This Skill

Use this skill when:
- Writing CREATE NANOFLOW statements
- Debugging nanoflow validation errors
- Understanding nanoflow restrictions vs microflows
- Building mobile or offline-capable features

If you're not sure whether the logic belongs in a nanoflow or a microflow, read the next section first. The mirror lives in [write-microflows](../write-microflows/SKILL.md) — keep both copies in sync.

## When to Use a Nanoflow vs a Microflow

| Scenario | Use |
|----------|-----|
| Client-side form validation before save | Nanoflow |
| UI navigation and page routing | Nanoflow |
| Calling device features (GPS, phone, camera) | Nanoflow |
| Offline data access and local storage | Nanoflow |
| Calling JavaScript actions (NanoflowCommons) | Nanoflow |
| Showing progress indicators / confirmation dialogs | Nanoflow |
| Querying the database | Microflow |
| Calling REST services or external actions | Microflow |
| Running Java actions | Microflow |
