context-budget: Managing the Context Window as a Budget

This plugin aims to address long-task failures that often occur around the 80% mark due to re-reading and re-derivation by managing the context budget. Its core features include a hierarchical reading strategy that first reads file headers and then loads content on demand; immediate writing to persistent “working notes” once facts are established, to retain key information; and “checkpoint recaps” at task-stage transitions to reconstruct context. It is well suited for handling complex long-running tasks and significantly improves the stability of large language models when processing lengthy workflows.
