Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
preserve-session
Preserves Claude Code session history across project directory renames, moves, and copies by assigning each project a path-independent UUID and maintaining a global registry mapping UUID to current path. Addresses a long-standing pain point: --resume and --continue silently lose session history when paths change. Closes anthropics/claude-code#5768; also tracked in #38089, #28745, #26766, #27883. Commands: /preserve-session:fix recovers sessions after rename/move (with copy detection and automatic .jsonl merge on destination collision), /preserve-session:inherit copies session history from another registered project, /preserve-session:doctor diagnoses hash/registry state and slug collisions including non-ASCII path issues on macOS, /preserve-session:uninstall removes all preserve-session data with a preview-then-confirm safety pattern. A SessionStart hook auto-initializes .claude/hash.txt on first run — zero manual setup. Demo: https://www.youtube.com/watch?v=lWMrzASG7_o Quality signals: 24 verified test scena
