Workflows

Before Implementing a Plan

After exiting plan mode, before writing any code:

1. vigil_save(name="before-<plan-name>") — snapshot the project
2. Implement the plan
3. If something goes wrong: vigil_diff(name="before-<plan-name>") then vigil_restore(name="before-<plan-name>")

Before Risky Changes

Before refactors or multi-file changes:

1. vigil_save(name="before-refactor") — named checkpoint
2. Make changes safely
3. If something breaks: vigil_diff first, then vigil_restore

Recovery

Always diff before restoring:

1. vigil_list() — see available checkpoints
2. vigil_diff(name="checkpoint") — preview what would change
3. vigil_restore(name="checkpoint") — restore files
4. Displaced files are preserved in .claude/vigil/artifacts/

Storage Management

Vigil has 3 named slots + 1 rotating ~quicksave:

• ~quicksave is ONE rotating slot — overwritten on each destructive command
• Named checkpoints persist until deleted
• Run vigil_list() periodically to check capacity
• When nearing capacity (2+ named checkpoints), offer to clean up the oldest with vigil_delete(name="oldest")
• vigil_restore preserves displaced files in .claude/vigil/artifacts/ — ask the user before cleaning those up
