cc-front-compaction

Front-only compaction compresses the oldest N% of a conversation while keeping recent interactions fully intact. It injects replay information for compacted sections to maintain context continuity, ensuring Claude retains access to crucial earlier parts without degrading performance.

Hard tail replay injection automatically inserts replay information for the compacted conversation sections. This ensures continuity by restoring necessary context from the compressed oldest N% of the session history without requiring manual reconstruction.

Yes, you can specify the percentage of context to compact by passing an optional argument to the compaction command. For example, running the command with the argument 30 compacts the oldest 30% of the current session's conversation history.

Front-only compaction is an effective approach to manage large contexts, as it selectively compresses older conversation parts rather than the entire history. This maintains a manageable context window and optimizes performance while preserving recent interaction relevance.

Claude Code sessions slow down with large context windows because the AI must process extensive conversation history. Front-only compaction solves this by compressing the oldest N% of the session, reducing the active context size while retaining crucial earlier information through replay injection.
