This handles the annoying problem of context windows filling up during long coding sessions. It creates structured SESSION.md files that track your progress, learnings, and decisions so you can pick up where you left off after Claude forgets everything. The skill has two modes: starting fresh sessions with goals and context, or resuming existing ones by reading your last checkpoint. It also encourages atomic commits at natural breakpoints. With 357 installs and solid audit results from the trust hubs, it seems like developers are actually using it. If you regularly hit context limits on bigger features, this is worth trying instead of manually summarizing "what we were doing" every time.
