Claude gets no-code evals for Agent Skills
Anthropic just upgraded its skill-creator tool with no-code testing and benchmarking features designed for non-engineer skill authors. The update introduces eval writing, parallel multi-agent test runs, blind A/B comparator agents, and a prompt optimizer to fix misfiring skills. Why it matters: as foundation models change, skills can quietly break or become redundant; this brings software testing rigor to workflow prompts without writing code.
