verification-before-completion

🎯Skill

from obra/superpowers

What it does

Validates and cross-checks critical task parameters, inputs, and preconditions before finalizing complex workflows to prevent errors and ensure reliable execution.

Overview

A skill from the Superpowers collection by Jesse Vincent (obra) that validates and cross-checks critical task parameters before claiming work is complete. Enforces the principle: evidence before claims, always.

Key Features

Mandatory verification gate before any completion claims
Red-Green cycle verification for TDD regression tests
Prevention of common rationalization patterns ("should work now", "I'm confident")
Checklist for different claim types (tests pass, build succeeds, bug fixed)

Who is this for?

Developers who want Claude to always verify its work before claiming completion. Prevents the common AI behavior of claiming "tests pass" without actually running them.
