Lookup Schema Definition

Look up and explain a Copilot Studio YAML schema definition.

Instructions

Run the schema lookup script to find the definition:

   node ${CLAUDE_SKILL_DIR}/../../scripts/schema-lookup.bundle.js lookup $ARGUMENTS

If the definition is not found, search for similar definitions:

   node ${CLAUDE_SKILL_DIR}/../../scripts/schema-lookup.bundle.js search $ARGUMENTS

If the definition contains $ref references that need resolution, use:

   node ${CLAUDE_SKILL_DIR}/../../scripts/schema-lookup.bundle.js resolve $ARGUMENTS

Present the schema definition in a readable format, explaining:
What the element does (from the description)
Required properties
Optional properties and their types
Any related definitions that might be useful

Example

User: /lookup-schema SendActivity

Response should include the full schema definition and explain how to use it in YAML.

How to use it

Copy the folder

Take microsoft/lookup-schema from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
