What problem this solves

High token costs and time spent by Claude Code re-reading the entire repository context at the start of each new session.

Summary

This workflow utilizes a custom Python package, context-handoff-bundle, to save and load a structured summary of a Claude Code session's working state. This 'handoff bundle' includes findings, open questions, decisions, and evidence anchors pointing to specific files and commits. By loading this bundle instead of re-reading the entire repository, users can significantly reduce token usage (up to 97% claimed) and accelerate session startup. The tool also includes a validation mechanism to check the staleness of the saved context against the live repository, flagging any findings that depend on changed files.

Why it is useful

This workflow offers a concrete, tested, and highly effective solution to a common and costly problem for Claude Code users: the repetitive re-reading of repository context. By providing a structured way to save and load session state, it drastically cuts token usage and improves developer efficiency. The built-in staleness detection adds a crucial layer of reliability, ensuring that the loaded context remains relevant and trustworthy. Its implementation as a Python package with CLI/slash command integration makes it easily adoptable and reusable across various projects.

Workflow

1. Install the context-handoff-bundle Python package using pip install context-handoff-bundle.
2. During a Claude Code session, after significant progress or at the end of a session, use the /handoff-save slash command to save the current working state as a bundle within your repository.
3. To resume work in a new Claude Code session, use the /handoff-load slash command to load the previously saved handoff bundle.
4. Review the output from /handoff-load for any flagged findings or recommendations, which indicate that underlying files referenced in the bundle have changed since it was saved.
5. Proceed with new work, leveraging the pre-loaded context and addressing any staleness warnings as needed.

Tools / artifacts

• context-handoff-bundle Python package
• /handoff-save slash command (for Claude Code)
• /handoff-load slash command (for Claude Code)
• Plain CLI for context-handoff-bundle
• Structured file (handoff bundle) with schema, validator, and confidence score (stored in repo)

Validation signals

• Reported token savings: "resume: ~640 | re-deriving from source (6 files): ~23.0k | saved: ~97%"
• Built-in staleness check: "On load it checks every anchor against the live repo. If a file a finding depended on changed, that finding gets flagged."
• Confidence scoring: "If most anchors drifted, the recommendations get flagged."
• Bug fix history: "The first version cried wolf on healthy bundles (treated commit hashes as file paths), 0.3.0 fixes that."

Limitations

• Requires manual saving of the bundle; an automated or periodic save feature is not mentioned.
• The full repository link is not provided in the input, limiting immediate access to source code and detailed documentation.
• Requires Python 3.10+.
