doodledood/claude-code-plugins/rewrite-history

Rewrite the current branch's history into clean, narrative-quality commits suitable for code review.

Goal

Transform messy development history into a logical story reviewers can follow commit-by-commit. Original branch is rewritten; backup preserved for rollback.

Arguments

$ARGUMENTS = optional flags (--auto skips interactive approval)

Preconditions

Abort with clear error if:

• On main/master branch
• Uncommitted changes exist
• No commits to rewrite (branch matches main)

Execution

1. Create backup branch: {branch}-backup-{timestamp} — permanent until manually deleted
2. Analyze the diff between current branch and main—understand the complete change set
3. Create temp branch from main for clean reimplementation
4. Plan the narrative—structure changes into logical, self-contained commits (foundations → features → polish)
5. Reimplement by recreating changes commit-by-commit with conventional commit messages; use --no-verify for intermediate commits
6. Verify byte-identical: git diff {original-branch} MUST be empty—abort if any difference
7. Replace original branch: point original branch to clean history (final commit runs hooks normally)
8. Offer to push with --force-with-lease

Verification Requirement

The byte-identical check is non-negotiable. If git diff {backup-branch} shows ANY difference after reimplementation:

• Abort immediately
• Report exactly what differs
• Leave backup branch intact for recovery

Constraints

• Analyze the complete diff only—ignore original commit history
• One concern per commit—atomic, independently revertible
• Conventional commit messages: type(scope): description
• Never add "Co-Authored-By" or "Generated with Claude Code"
• Always use --force-with-lease for push (never --force)

Interactive Mode

Unless $ARGUMENTS contains --auto:

• Present proposed commit plan before execution
• Allow adjustment or cancellation

Rollback

If anything goes wrong: git reset --hard {branch}-backup-{timestamp}

Output

Report commit count, backup branch name, and the new commit log.
