commit-dance

A process for reorganising a software branch’s messy commit history into a clear sequence that explains the work step by step.

In plain words
What is it for?
Use it after follow-up fixes or review changes have created many commits and the branch needs a coherent, file-by-file story before merging.
Why use it?
It makes a pull request easier to review and preserves the exact final files while changing only their history. A force-push may affect others using the branch.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

commit-dance scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Commit Dance

Overview

Re-cluster the commits on a feature branch into a clean pedagogical narrative after the original work has accumulated additional fixes, bug repairs, or review tweaks. The "dance" is the choreographed sequence:

backup → soft reset → re-commit pedagogically → verify zero-diff → force-push with lease

Core invariant: the final tree must be byte-for-byte identical to the pre-dance tree. Only the commit history changes shape — never the working tree.

When to Use

  • Long PR review: many "address review" / "fix typo" / "wip" commits accumulated; reviewer wants to walk the changes as a story
  • Combining the original feature work + bug fixes discovered during testing into thematic chapters
  • A branch that has the right code but a history that hides the architecture
  • BEFORE merging a PR you want to be readable later as a learning artifact (pedagogical-pr-review)

Don't use when:

  • The branch has merged commits from main/development (rebase those out first, separately)
  • Other people are actively pulling the branch (force-push will require them to reset)
  • The history is already clean and the only goal is "tidy commit messages" (use git commit --amend per commit instead)
  • You're not certain about the chapter boundaries (do pedagogical-pr-review or planning first)

Quick Reference

Step Command Critical
1. Verify branch git branch --show-current && git status --porcelain Tree clean OR only intended unstaged fixes
2. Backup tag git tag <branch>-original-$(date +%Y-%m-%d-%H%M) Before anything destructive
3. Backup commit log git log --oneline <base>..HEAD > /tmp/<branch>-original.txt For human reference
4. (optional) Backup branch git push origin <branch>:<branch>-backup Offer; never auto
5. Plan chapters Show original commits + file diff; propose mapping Get user approval
6. Soft reset git reset --mixed $(git merge-base HEAD <base>) --mixed, NEVER --hard
7. Per chapter git add <files> && git commit -m "..." Stage subsets, not -A
8. Verify zero-diff git diff HEAD <backup-tag> shows ONLY intentional fixes Stop if anything unexpected
9. Run tests Project-specific (lint + unit + integration) Confirm new HEAD is functional
10. Push git push --force-with-lease NEVER --force

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

commit-dance is a skill published in the GitHub repository marinahaugen/polymorph-mindset-plugins (4 stars, last pushed 2mo ago), licensed MIT. It adds 52 tokens to every session and 3,051 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
