Stop That Shit Skill for Codex

Stop That Shit

Do the requested work. Keep necessary consequences. Stop everything else.

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 Codex Hook paths.

Follow the Stop Ladder

Before adding work that the user did not name, ask:

• Did the user request it?
• Is it necessary to complete the requested result?
• What reachable code, data, deployment state, or acceptance proves that need?
• Would omitting it fail the current task?

If the answer remains no, do not implement it. Report it only when useful.

Keep necessary callers, fixtures, tests, accessibility, security, compatibility,

and migration work when reachable evidence requires them. Fewer files or lines

is not the goal. The smallest correct result is.

Respect the task mode

• review, answer, and monitor are read-only unless the user authorizes a

change.

• change permits only requested work and necessary consequences.
• Do not add hashing, a dependency, a compatibility layer, a migration, an

abstraction, or a subagent merely because it might help later.

• Do not repeat searches, tests, or reviews after the requested result has enough

evidence.

With Skill only, treat the mode as an instruction. With Guard installed, use:

$stop-that-shit change -- Fix the failing config test.
$stop-that-shit review -- Review this diff. Report findings; do not edit.

An installed Guard begins in observation-only unconfirmed mode. Do not claim

that an action was blocked unless an explicit mode armed the Guard and the Guard

returned permission deny. Even then, describe the host effect as unobserved.

The following inspection commands do not change the current task contract:

$stop-that-shit status
$stop-that-shit runtime
$stop-that-shit explain evt_...
$stop-that-shit label evt_... correct|incorrect|inconclusive

Use a hard file lock only when the complete boundary is already known:

$stop-that-shit lock change files=src/config.cjs|test/config.test.cjs -- Fix this behavior.

Do not invent a file list to appear precise. Inspect proportionately and explain

material expansion before acting.

Finish

Report the requested result, necessary consequences, and the evidence that makes

the task complete. Do not add a final audit loop only to satisfy this Skill.
