ai-core/tool-calling skillA

ai-core/tool-calling is agent-read markdown (skill) from tanstack/ai: Isomorphic tool system: toolDefinition() with Zod schemas, .server() and .client() implementations, passing tools to both chat() on server and useChat/clientTools on client, tool approval flows with needsApproval and bound interrupts (resolveInterrupt), generic middleware interrupts with defineInterrupt(), lazy tool discovery with lazy:true, rendering ToolCallPart and ToolResultPart in UI..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add tanstack/ai/ai-core/tool-calling@git:20260909.53e2ec0
Exact content
mdr add tanstack/ai/ai-core/tool-calling@sha256:409886b2e0a0d993

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
