skill entry (v1)

skill-entry.v1.schema.json

Overview

The common entry core plus an embedded SKILL.md-style frontmatter object and the fields Project #24 specifies as required for a certifiable skill: defined inputs, outputs, provenance logging, human oversight requirements, and evaluation criteria (internal project documentation Section 3.5.3, internal project documentation Section 6.4). source.repository is shaped to match agentregistry's Skill kind so a future integration is a mapping exercise, not a schema rework; its url is any externally hosted git repository, not limited to a GA4GH-controlled host.

Full specification: spec/skill-card.md

This schema extends entry-core.v1.schema.json via allOf: every entry-core field is also required or available on this entry type, in addition to the fields below. This entry type additionally requires: skill, source, inputs, outputs, human_oversight, provenance_logging, evaluation_criteria_uri. No properties beyond entry-core's and those listed below are permitted on this entry type.

Properties

typestringoptional
Always "skill" for entries of this type.
- Fixed value: "skill"
skillobjectrequired
Embedded SKILL.md-style frontmatter. Ecosystem-specific frontmatter fields beyond name/description are preserved as-is (additionalProperties intentionally open, mirroring Claude Code's own tolerance of unrecognised SKILL.md frontmatter keys).
Additional fields beyond those listed here are permitted.
