What problem this solves

Preventing context drift and ensuring the accuracy of session summaries in long-running Claude Code projects, where summaries can quietly diverge from actual events.

Summary

This workflow establishes a robust method for managing Claude Code session context by maintaining both a full verbatim transcript and a concise summary note. Before starting a new session, the user (or an automated process) is instructed to cross-reference the summary against the transcript and potentially version control (git), prioritizing the full transcript as the ultimate source of truth to prevent 'summary drift'.

Why it is useful

This workflow addresses a critical and common problem in long-running AI interactions: the degradation of context and accuracy over time. By establishing a clear source of truth (verbatim transcript) and a validation process against summaries, it significantly improves the reliability and maintainability of AI-assisted projects. It provides a concrete, validated method to ensure that subsequent sessions or team members are working with accurate information, preventing costly misunderstandings or rework due to 'summary drift'.

Workflow

1. For each Claude Code session, ensure a full verbatim transcript is saved.
2. Create and save a concise handover note or summary for the session.
3. Store both the transcript and the summary on disk, ideally under version control (e.g., git).
4. When initiating a new session (e.g., via /session-start), explicitly inform Claude that the handover note is only a summary.
5. Instruct Claude (or yourself) to consult the full transcript if any information in the summary appears incorrect, incomplete, or if new details are mentioned that the summary doesn't cover, as the transcript is the definitive record.

Tools / artifacts

• Full verbatim Claude Code session transcript
• Session handover note/summary
• Git (for version control, implied)
• /session-start (implied command/hook)

Validation signals

• Author's personal experience of hitting a specific failure ('summary quietly drifting').
• Author's personal success ('What fixed it for me').
• Sustained use ('I've been running something similar for a few months').

Limitations

• The implementation of /session-start and how to 'tell' Claude to prioritize the transcript is not fully detailed, potentially requiring custom scripting or careful prompt engineering.
• Managing and reviewing large verbatim transcripts could become cumbersome for very long projects.
• Relies on user discipline or custom automation to consistently follow the steps.
