From the source SKILL.md

Use this skill when an integration needs to group multiple Salesforce REST API operations into a single HTTP round trip. The Composite family of resources — /composite/, /composite/sobjects/, /composite/tree/, and /composite/batch/ — each serve distinct use cases and carry distinct limits. Choosing the wrong resource wastes API calls, violates atomicity requirements, or silently drops errors.
