ai:agent

This skill should be used when the user asks to "design agent tools", "create tool descriptions", "reduce tool complexity", "implement MCP tools", or mentions tool consolidation, architectural reduction, tool naming conventions, or agent-tool interfaces.

From the source SKILL.md

Tools are the primary mechanism through which agents interact with the world. They define the contract between deterministic systems and non-deterministic agents. Unlike traditional software APIs designed for developers, tool APIs must be designed for language models that reason about intent, infer parameter values, and generate calls from natural language requests. Poor tool design creates failure modes that no amount of prompt engineering can fix. Effective tool design follows specific principles that account for how agents perceive and use tools.

What this skill does

tool-design is a community-contributed Claude Code skill in the design-creative sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/tool-design--skills-chakshugautam/ and loads when your prompt matches the skill's trigger.
