Context Ledger extends Claude Code sessions by 28x
The developers introduced Context Ledger, which addresses context window overflow for long-running projects. Instead of discarding old data or lossily compressing it, the tool uses git commits as archival boundaries.
On each commit, Context Ledger creates a compact record with key decisions, interfaces, and a pointer to the exact bytes of code in the git history. When the agent needs old feature details, it retrieves them from git on demand. This approach preserves 93% accuracy on past development queries while using 5x fewer tokens than working with the full context.
The tool installs as a CLI utility with hooks for Claude Code. It’s available on GitHub.
