Stop That Shit: security tool for Hermes Agent

Hook and skill guard that stops AI coding agents from unrequested checksums and scope creep

What Stop That Shit does

Stop That Shit, abbreviated STS, targets four habits it calls SHIT: scope creep, hashing and hypothetical hardening, intent violation, and task thrashing. Examples from the README include writing a SHA-256 file nobody reads, editing files during a read-only review, and rerunning checks that already answered the question. The guard keeps necessary work, such as updating callers and migrating published data, and trims extras that serve no current purpose.

It ships as a Skill plus a Guard hook for Codex, Claude Code, OpenCode, the Hermes Agent CLI and Pi. A skill-only install is available for people who do not want execution blocking. The README cites 18 public Bad/Good test cases, with evidence and paired Codex runs documented in the repository. Setting hash=allow lets a checksum through when a release process really reads it. The README is mainly in Chinese, with English and Korean versions.
