surrogate-verifier

Information-isolated verification skill that generates structured test assertions and failure diagnostics for skill packages. Given a skill definition and task prompt, produces machine-checkable assertions (contains, regex, format, tool-call checks) and root-cause diagnostics when assertions fail. Implements the surrogate verifier role from co-evolutionary skill generation (EvoSkills). Triggers on: "verify this skill", "generate assertions for", "surrogate verification", "test this skill output", "diagnose skill failure", "generate test cases for skill", "skill verification", "assertion generation", "check skill quality against tasks", "generate eval assertions". Use this skill when evaluating skill output quality through automated assertion testing rather than manual review. NOT for general code review (use pr-review). NOT for package metadata evaluation (use package-evaluator). NOT for test suite generation for application code (use test-harness).
