josh/context-checkpoint v1.0.0

Save critical working context to structured markdown files before an agent's context window fills up, so future agents can resume without repeating failed approaches or losing hard-won knowledge. Use this skill whenever you notice your context is getting large, when a manager agent tells you to checkpoint, when you are about to be replaced by a fresh agent, or when you have accumulated significant learnings that would be costly to rediscover. Also trigger when anyone mentions context checkpoint, save context, preserve context, session handoff, context running low, or context continuity.
