Automates the archival of low-signal and aged Claude Code sessions to maintain a clean and focused workspace.
The Session Harbor Cleanup skill provides a robust utility for managing your session history by identifying and archiving 'low-signal' interactions. It evaluates sessions based on age, user-message count, and the presence of meaningful metadata like tags or notes, while filtering out boilerplate content such as environment context blocks. This skill is essential for developers using Claude Code who want to prevent history bloat by automatically pruning short-lived or non-substantive sessions while ensuring that valuable interactions remain preserved.
