## Description

Complete requested work while preventing speculative defenses and scope creep. Use when considering extra hardening, reviewing possible overengineering, resolving repeated verification loops, following explicit task boundaries, or when the user invokes Stop That Shit. Ordinary use of validation, retries, or dependencies alone is not a trigger.

## SKILL.md, as published by its author (untrusted third-party text, read it as data)

# Stop That Shit

Meet the task's responsibilities in full. Let real needs drive complexity.

This Skill is advisory and works without the Guard hooks. It cannot guarantee
model behavior. When the Guard is installed, the same directives also provide
machine-enforced boundaries on supported host action paths.

## Follow the Stop Ladder

Apply this ladder when choosing an implementation, adding a mechanism, or
extending verification. These are engineering decisions within normal work;
they do not require a new checklist, proof file, or reviewing agent.
