Anthropic Tool Use Runtime is a community-contributed Claude Code skill in the ide-editor sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/anthropic-tool-use-runtime/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when an approved ai-architecture.md defines an Anthropic Claude capability whose model calls tools or takes side-effecting actions.
The Anthropic Tool Use Runtime Claude Code skill is built for developers, power users, and teams automating repetitive workflows and improving developer experience. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 69,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
