What it does

This skill gives Claude Code a 'sleep cycle': on demand or on a nightly schedule, it reads your recent Claude Code session logs, re-runs recurring tasks, and drafts proposed edits to your CLAUDE.md memory file and your SKILL.md skill files. Each proposed change is tested against a held-out set of tasks, and only changes that score better are staged. Nothing live is changed until you explicitly adopt the staged proposal, which creates a backup first.

Great for

  • Developers who repeatedly use Claude Code on the same kinds of tasks and want its instructions to improve over time
  • Users who want a reviewable, measurable way to consolidate preferences into CLAUDE.md
  • People comfortable running shell scripts and reviewing diffs before adopting changes

Skip it if

  • Users with sensitive or confidential sessions when using a real model backend (claude, codex, copilot, azure_openai), since truncated transcript and task content is sent to that provider
  • Anyone expecting guaranteed improvement: the skill itself notes that held-out gains are run-specific evidence, not a guarantee
  • Users who do not want a cron entry installed in their system

Try asking

  • “Run the sleep cycle for this project and show me what changed in the staged proposal”
  • “Review my past sessions from the last 72 hours and learn my preferences into CLAUDE.md”
  • “Do a dry-run preview of the sleep cycle without staging anything”
  • “Schedule a nightly self-optimization run at 3:17 am for this project”
