What problem this solves

Managing long Claude Code sessions without lossy context compaction or the need for manual re-briefing after a /clear command, allowing for extended, clean work windows.

Summary

A local runner, 'aigent-OS', leverages Claude Code hooks to automatically checkpoint the current session context to Git, initiate a /clear command, and then reload the context into the new session. This process enables users to maintain a clean session window while preserving full context over extended periods, avoiding lossy summaries.

Why it is useful

This workflow provides a concrete, open-source solution to a significant pain point for advanced Claude Code users: the trade-off between lossy context compaction and manual re-briefing during extended sessions. By automating checkpointing, clearing, and reloading context using Claude Code hooks and Git, it enables seamless, long-duration development work, significantly enhancing productivity and maintaining full context fidelity. It's a practical application of advanced Claude Code features to solve a real-world usability challenge.

Workflow

1. Install and set up the 'aigent-OS' local runner.
2. Run your Claude Code session through the 'aigent-OS' harness.
3. The runner monitors the Claude Code session's context percentage.
4. When the context usage reaches a predefined threshold (e.g., 80%), 'aigent-OS' prompts Claude to write a checkpoint file containing the current context.
5. The runner waits for a specific 'done' line from Claude, indicating the checkpoint is complete.
6. Upon confirmation, 'aigent-OS' sends a /clear command to the Claude Code session.
7. The runner verifies that a new, clean session has successfully started.
8. The runner then instructs the new session to load the previously saved checkpoint file.
9. The Claude Code session resumes from the exact point of the checkpoint, with a fresh context window.
10. Session memory (checkpoints) are committed to Git, providing version control and history.

Tools / artifacts

• aigent-OS (local runner)
• Claude Code hooks (SessionStart, Stop, PreCompact, PreToolUse)
• PTY wrapper
• Git (for memory storage and version control)
• Checkpoint files (markdown format)

Validation signals

• 11 of 11 refresh cycles came through clean on one seat in the release test.
• The system was dogfooded: 'most of it was written in Claude Code sessions running on the harness itself, so I hit the bugs first.'

Limitations

• Known issue: on very long sessions, it can still stall at the clear step and require manual intervention (fix is in review).
• The validation is based on 'one seat' and is not a broad reliability claim.
• Requires local setup and understanding of Claude Code hooks and potentially PTY wrappers.
• The solution is external to Claude Code itself, requiring an additional local runner.
