Agent SDK Definitions is a production-ready Claude Code skill (quality score 70/100) in the tools-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/agent-sdk-definitions/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when creating agents for SDK-based applications rather than filesystem-based Claude Code.
The Agent SDK Definitions skill is built for developers, power users, and teams automating repetitive workflows and improving developer experience. It is part of the open ClaudSkills registry, a community-curated catalog of 15,000+ capabilities you can install for Claude Code — the Claude CLI agent.
mkdir -p ~/.claude/skills/agent-sdk-definitions curl -L https://claudskills.com/skills/agent-sdk-definitions/SKILL.md \ -o ~/.claude/skills/agent-sdk-definitions/SKILL.md
Or just download SKILL.md directly and drop it into ~/.claude/skills/agent-sdk-definitions/. Claude Code auto-discovers it on next session.
Skills live at ~/.claude/skills/agent-sdk-definitions/SKILL.md on macOS/Linux, or %USERPROFILE%\.claude\skills\agent-sdk-definitions\SKILL.md on Windows. See the full install guide for step-by-step instructions.
