Google ADK Skills Architecture Overview
The Google Anthropic Development Kit (ADK) introduces a novel approach to managing specialized knowledge within AI agents through its Skills architecture. This system is designed to address the scalability challenges of building intelligent, domain-specific applications by allowing agents to dynamically load and unload knowledge as needed.
Key Components of ADK Skills Architecture
-
Three-Level Progressive Disclosure:
- Level 1 (L1) Metadata: Contains basic information about a skill, such as its name and description.
- Level 2 (L2) Instructions: Detailed instructions on how to use the skill, including specific tasks it can perform.
- Level 3 (L3) Resources: Actual data or executable scripts that are loaded only when necessary.
-
SkillToolset:
- A container for multiple skills and their associated resources. It includes a code executor to run any scripts within L3 resources securely.
Workflow Example
- Query Handling:
- When an agent receives a query, it first scans the available skills (L1 metadata).
- If a relevant skill is identified, the agent loads its instructions (L2) and then fetches only the
