Included Skills2

checkpointskills/checkpoint/SKILL.md

Use when capturing a durable session handoff to STATE.md so work resumes cleanly in a fresh session. Triggers — "/checkpoint", "/checkpoint:checkpoint", "snapshot state", "save a handoff", "checkpoint before I stop", or any checkpoint-plugin hook nudge (context pressure, post-compact pickup, Stop-hook write-up). SKIP for: trivial/short sessions where STATE.md adds nothing; routine `/compact`; the CLI's built-in checkpoint/rewind feature, which is unrelated to this skill.

keepalive-statusskills/keepalive-status/SKILL.md

Report cache-keepalive health: tick cadence, cache hits vs busts, and whether keepalive is enabled. Manual /keepalive-status.
