What Tool Schema Design does

Tool Schema Design helps define model-facing tools with clear names, bounded JSON Schema parameters, explicit side effects, and safe defaults. Use it when building function-calling or MCP tools and when models choose the wrong tool or invent arguments.

Tool Schema Design is cataloged under AI Engineering on DirSkills. Tool Schema Design comes from a repository tagged agent-skills, ai-agent-skills, ai-agents, awesome-list and claude-code.

Documentation

README

Excerpt

Tool Schema Design

Make the safe, intended call easier for a model to choose than an ambiguous or destructive alternative.

Use when

Add or revise a function-calling, MCP, plugin, or internal agent tool.
Split an overloaded API operation into model-usable actions.
Reduce wrong-tool selection, malformed arguments, or fabricated fields.
Document authorization, confirmation, idempotency, and error behavior.

Inputs

Collect supported user intents, backend operation semantics, required credentials, actor and tenant scope, side effects, reversibility, latency, rate limits, failure modes, and provider-specific schema constraints. Obtain representative valid and invalid requests.
