The document's frontmatter supplies the skill's name and description, which are validated against the Agent Skills standard: the name must be lowercase letters, digits, and single hyphens, and a description is required because it is the only signal the model has when deciding whether to use the skill. To create one from a zipped directory instead, use managedAgentsPublishSkillBundle. Do not automatically retry an ambiguous transport failure: list skills first, because this operation does not replay a prior response and another submission can create another skill. ## OpenAPI ````yaml /managed-agents/openapi.yaml post /managed-agents/v1/skills openapi: 3.1.0 info: title: Managed Agents API version: 0.14.0 description: >- The Recursion Managed Agents REST API.
