Agent Skill
An Agent Skill is a high-level, reusable capability bundle that AI agents adopt — specialized prompts/instructions plus the tools needed to apply them. Skills sit one level above tools: where a tool is a single callable, a skill packages domain expertise (the "how" and "when") together with the low-level tools it relies on. The same skill can be adopted by many agents, so modeling it as its own entity avoids duplicating that expertise on every agent.
Skills follow a "git as source of truth" pattern (e.g. the agentskills.io standard): the skill is defined in a repository and cataloged in DataHub for discovery, governance, and reuse.
Identity
Agent Skills are identified by a single field:
- id: A unique identifier for the skill, typically a human-readable slug such as
customer-service-skillor a generated UUID.
An example URN is urn:li:agentSkill:customer-service-skill.
Important Capabilities
Skill Info
The agentSkillInfo aspect holds the skill's definition:
- name: Display name, searchable with autocomplete.
- description: What the skill does and when to use it.
- instructions: The markdown body of the skill's
SKILL.mdfile (excluding YAML frontmatter) — the execution guidance loaded when the skill is activated. - sourceRepository: Where the skill is defined (see below).
- requiredTools: The API entities the skill needs to operate (
SkillRequiresTool). - created / lastModified: Audit stamps.
Source Repository
The sourceRepository field (a SkillSourceRepository) points to the git location that owns the
skill definition. It carries either a repositoryUrn (preferred, when the Repository
is already cataloged in DataHub) or an external url, plus a path to the definition file within the
repository (e.g. customer-service/SKILL.md).
Relationship to Agents
Agents adopt skills via the AgentHasSkill relationship declared on the agent's
aiAgentDependencies aspect — so an Agent Skill profile surfaces the agents that use it, and a skill
in turn exposes the tools it requires. This makes the agent → skill → tool chain traversable from
either end.
Governance and Versioning
Agent Skills support the standard governance aspects — ownership, tags, glossary terms, domains,
structured properties, and institutional memory — plus native versioning (versionProperties).
Technical Reference Guide
The sections above provide an overview of how to use this entity. The following sections provide detailed technical information about how metadata is stored and represented in DataHub.
Aspects are the individual pieces of metadata that can be attached to an entity. Each aspect contains specific information (like ownership, tags, or properties) and is stored as a separate record, allowing for flexible and incremental metadata updates.
Relationships show how this entity connects to other entities in the metadata graph. These connections are derived from the fields within each aspect and form the foundation of DataHub's knowledge graph.
Reading the Field Tables
Each aspect's field table includes an Annotations column that provides additional metadata about how fields are used:
- ⚠️ Deprecated: This field is deprecated and may be removed in a future version. Check the description for the recommended alternative
- Searchable: This field is indexed and can be searched in DataHub's search interface
- Searchable (fieldname): When the field name in parentheses is shown, it indicates the field is indexed under a different name in the search index. For example,
dashboardToolis indexed astool - → RelationshipName: This field creates a relationship to another entity. The arrow indicates this field contains a reference (URN) to another entity, and the name indicates the type of relationship (e.g.,
→ Contains,→ OwnedBy)
Fields with complex types (like Edge, AuditStamp) link to their definitions in the Common Types section below.

semanticContent
Semantic content for enabling vector similarity search.
This aspect stores chunked text and embedding vectors for any entity that supports semantic search. Generation of the data for this aspect should be built in tight collaboration with the embedding generator during semantic search query processing. Chunk determination and generation can happen somewhat independently The data in this aspect is directly passed along to the semantic search index.
Design notes:
- Supports multiple embedding models (e.g., different providers or versions)
- Supports chunked content for long documents
- Text field is optional to support privacy-sensitive use cases where only embeddings (not source text) are shared with DataHub
