• ledger — Heavily inspired by (i.e. copied from) Keepsake (which is sadly no longer maintained), but rewritten in Rust. Like Keepsake, it logs experiment results, snapshots code and artifacts, and lets you time-travel back to prior experiments—their results, code, and local artifacts. Updated for the autoresearch era: agents can run experiments in a loop while Ledger logs results and snapshots the code and artifacts behind every run. This makes it easy to audit what an agent tried, compare code changes and results across experiments, and restore any prior state—without littering your Git history with experimental commits or having to deal with worktrees (gross).
  • s3_tui — A Rust terminal interface for navigating S3 files.
