About this skill
What it does
Tool Use Coach transforms haphazard AI tool execution into a structured, reliable workflow. It forces agents to plan, verify, and use the principle of least privilege when selecting tools. Instead of your agent "hallucinating" tool calls or performing redundant actions, this skill implements a strict protocol for evidence-based tool use.
Why use this skill
Prompting an AI to "use tools" often leads to inefficient loops or risky, irreversible actions. This skill provides a developer-centric framework that emphasizes:
- Tool Minimalalism: Choosing the smallest, safest tool for the job.
- Verification First: Treating tool output as claims that must be validated against the goal.
- Risk Mitigation: Preventing chained irreversible actions without intermediate checks.
- Failure Recovery: Implementing systematic fallback patterns when a tool call fails.
Supported Workflows
Designed for integration with any tool-enabled agent (like Claude Code, Cursor, or custom MCP setups), it provides a compact planning rubric and recovery patterns that work across search, edit, and execution toolsets.
