outsystems-custom-code SKILL.md skillA

This file is byte-identical to the first copy the registry indexed, one of 3 indexed copies. Same content hash, so the same checks give both the same grade.

outsystems-custom-code from outsystems/outsystems-mcp is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add outsystems/outsystems-mcp/outsystems-custom-code@v1.3.0

[Beta] Reference + workflow for building, testing, and deploying C# class-library "External Logic" libraries for OutSystems Developer Cloud (ODC). Covers SDK attributes ([OSInterface] / [OSAction] / [OSParameter] / [OSStructure] / [OSIgnore]), supported data types, optional parameters, logging via ILogger, project structure, runtime constraints (95s execution / 1 GB memory / 5.5 MB payload), unit + container integration tests, and deployment via the OutSystems MCP. Use when the user asks to…

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.

# OutSystems ODC External Library Skill

This file describes how to create, build, test, and deploy C# libraries for the OutSystems Developer Cloud (ODC) External Logic feature.

**Load the main `outsystems` skill before uploading: upload, polling and publish rules come from it** (read the live tool catalog, poll long-running operations to terminal, confirm before every tenant write). The main skill's upload, polling and publish rules apply, and this skill's two confirmations (see [Upload and publish](#upload-and-publish)) always apply on top of them. For building and packaging the library, follow this skill.

How to install

The exact contents, by fingerprint
mdr add outsystems/outsystems-mcp/outsystems-custom-code@sha256:f79cb7d8c64d1ace

The line at the top of this page pins the label v1.3.0, 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.
