Show HN: Lcc – compact Claude Code sessions without summarizing them (github.com)

The recently launched Lcc (Local Context Compiler) aims to enhance Claude Code sessions by compacting the coding-agent context without losing critical information. Unlike the existing /compact feature which summarizes sessions and can overlook essential details like exact errors or paths, Lcc maintains all user and assistant messages in their original form while effectively reducing the context size — reportedly achieving an average token reduction of about 21.8% across extensive user sessions. This keeps relevant outputs accessible for subsequent recalls, thus improving workflow efficiency for developers. This tool is significant for the AI/ML community as it addresses a common issue with session summarization, ensuring that vital information is not discarded during these processes. The compacted sessions can still achieve comparable performance to those using full context, with Lcc allowing developers to retrieve removed outputs easily. The local processing nature of Lcc, which does not rely on external APIs or network connections, further enhances security and efficiency, making it a practical addition for developers working with Claude Code and similar AI-powered coding environments.
