SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

CLAUDE 세션 시작 시 CLAUDE.md, WORK_HANDOFF.md, SESSION_LOG.md 등이 로딩될 때 과도한 컨텍스트 소비로 인한 Lost-in-the-Middle 위험을 줄이고, 과거 아카이브와 최근 세션의 중복 제거를 통해 초기 컨텍스트를 1,000줄 이내로 유지합니다.

Core Features & Use Cases

  • 과거 아카이브 + 최근 유지 + 중복 제거를 통한 자동 컨텍스트 압축으로 불필요한 텍스트를 줄입니다.
  • Phase-based 워크플로우로 측정, 다이어트, 압축, 아카이브, 중복 제거를 순차적으로 수행합니다.
  • 최종 산출물로 슬림화된 문서 세트와 아카이브 및 컨텍스트 감사 보고서를 제공합니다.

Quick Start

세션 시작 시 컨텍스트 압축 워크플로우를 실행하여 과거 아카이브와 최근 세션만 남기고 중복을 제거하라.

FAQPage Schema
How do I prevent Lost-in-the-Middle issues when loading large documents into Claude AI sessions?

Context compression for Claude AI sessions involves archiving past session logs and slimming recent documents to reduce initial context consumption. This prevents Lost-in-the-Middle by maintaining a single source of truth and keeping startup context under 1,000 lines through a phased workflow.

What is the best way to archive past Claude session logs and reduce startup context size?

The best way to archive past Claude session logs is to execute a phased workflow that sequentially measures, slims, compresses, archives, and deduplicates session context. This produces slimmed original documents, archived past records, and a context audit report to prevent Lost-in-the-Middle.

How do I manage CLAUDE.md and WORK_HANDOFF.md files to avoid excessive context consumption at startup?

Manage CLAUDE.md and WORK_HANDOFF.md files by applying context compression that deduplicates past archives and recent session logs. This phased workflow slims the original documents and outputs a context audit report, ensuring startup context remains under 1,000 lines.

Can I use a context compression workflow to maintain a single source of truth for Claude session documentation?

Yes, you can use a context compression workflow to maintain a single source of truth for Claude session documentation. It enforces a single source of truth by deduplicating past archives and recent sessions, outputting slimmed originals and a context audit report to prevent Lost-in-the-Middle.

What are the limitations of context compression for preventing Lost-in-the-Middle in Claude sessions?

The limitation of context compression for preventing Lost-in-the-Middle is that it is specifically applicable to Claude-powered sessions that load large documents at startup. It requires archiving past sessions and slimming the most recent ones to maintain initial context under 1,000 lines.
