How to Evaluate Skills for Safer Coding Agents

blair_hudson · reddit · 2026-07-07

A Reddit user shared an agent skill currently under development that helps coding agents like Claude Code, Codex, and OpenCode follow safer tool design principles during tool creation and review. It is applicable to MCP and native framework tool calls, based on the author's previous writing on "defensive tool design." The author is seeking a suitable benchmark for tool safety evaluation but to no avail, considering building one themselves and asking the community what a tool safety benchmark should cover. The goal is to make agents question high-risk operations, identify missing safeguards, clarify permission boundaries, and avoid unsafe tool calls.
