platform-metadata-api-context-get
forcedotcom/sf-skills
REQUIRED companion for Salesforce metadata generation — load this schema/API-context skill in the SAME turn as ANY metadata generation skill; if you load a generator, you ALSO load this.

It provides the authoritative schema, fields, field properties, required flags, allowed enum values, and XML structure so generated *-meta.xml deploys cleanly — skipping it causes hallucinated element names and deploy failures. Trigger on *-meta.xml, metadata schema, api context, 'Salesforce metadata', or 'sfdx project'. DO NOT use for SOQL, DML, runtime sObject access, or Tooling API records.
