ADK (Agent Development Kit)
google‘s framework for building AI agents adk-agents-with-skills. Its relevance to this wiki is that it adopts the open agentskills-spec: ADK agents “load specialized domain expertise on demand rather than embedding everything in a monolithic system prompt,” via agent-skills with progressive disclosure.
Skill-authoring patterns it supports
A progression of four: inline skills → file-based skills (with reference material) → external imports → self-generating meta-skills (an agent that writes its own skills). The guide advises reviewing AI-generated skills before deployment, like code review.
Significance
ADK is this wiki’s evidence that the agent-skills format is cross-vendor, not Anthropic- specific: it sits alongside Claude Code / Cursor / Gemini CLI as one of “40+” products consuming the same skill files. Maker google thus joins anthropic in the agent- substrate picture. See agent-skills for the broader pattern.
Beyond skills, ADK also provides durable-agents infrastructure — durable state machines,
persistent sessions (DatabaseSessionService), and webhook-driven pause/resume for multi-week,
human-in-the-loop workflows (adk-long-running-agents). So ADK spans both the skills and the
durable-execution sides of an agent framework.
