Endless Toil is a community-contributed Claude Code skill in the code-quality sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/endless-toil/ and loads when your prompt matches the skill's trigger.
When to invoke it: Use when the user wants Codex to scan code and play escalating groaning sounds based on suspicious code quality signals, especially requests like "make Codex suffer while reading this code", "play sounds based on code quality", "audible code review", or explicit use of $endless-toil.
The Endless Toil Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 115,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).
