Verification Before Completion Skill
Overview
Enforce rigorous, adversarial verification before declaring any task complete. Implements defense-in-depth validation with multiple independent checks to catch errors before they reach users. The core principle: verify independently rather than trusting executor claims — verify what ACTUALLY exists in the codebase through testing, inspection, and data-flow tracing.
This skill prevents the most common form of premature completion: claiming success without running tests, summarizing results instead of showing evidence, or trusting code that "looks right" without verification.
