What is commit-split?

A command that guides you through splitting one large Git commit into several smaller commits, with each commit containing one logical change.

Use it to analyze changed files, group related changes, choose their order, and create a conventional commit message for each group.

Smaller commits are easier to review, test, understand, and undo when something goes wrong.

commit-split — Command for Claude Code by dhofheinz/open-plugins

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/dhofheinz/open-plugins

Made for: Claude Code.

Or install git-commit-assistant, the plugin that ships this one along with the rest of its 3 commands, 1 agent.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00009	$0.05052
Opus 5.5	$0.00004	$0.02021
Sonnet 5.5	$0.00002	$0.01010
Haiku 4.5	$0.00001	$0.00505

Security

Grade A, and why

commit-split 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 1mo ago.

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 Split - Interactive Atomic Commit Creation

Overview

The /commit-split command provides an interactive workflow that orchestrates multiple skills to help you split large commits into focused, atomic commits. Each atomic commit represents one logical change that can be independently reviewed, tested, and reverted.

Skills Orchestrated

This command coordinates a complete execution workflow:

commit-error-handling - Pre-flight validation
- Operation: /commit-error-handling diagnose-issues
- Ensures: Repository ready for splitting
commit-analysis - Change understanding
- Operation: /commit-analysis analyze
- Provides: Type, scope, and file analysis for grouping
atomic-commit - Core splitting logic (PRIMARY)
- Operation: /atomic-commit interactive
- Provides: File grouping, suggestions, sequence generation
- This skill contains the core splitting algorithms
message-generation - Message creation
- Operation: /message-generation complete (per commit)
- Generates: Conventional commit message for each group
commit-best-practices - Quality assurance
- Operation: /commit-best-practices check-pre-commit (optional)
- Operation: /commit-best-practices review-commit (after each)
- Validates: Tests pass, quality maintained
history-analysis - Project awareness
- Operation: /history-analysis analyze-style (cached)
- Ensures: Messages match project conventions

Interactive Workflow

The /commit-split command provides a guided experience:

1. Analyze changes → Show plan
2. Group files → Present groups
3. For each group:
   - Show files and changes
   - Generate message
   - Get user approval
   - Create commit
   - Review quality
4. Final summary

Alternative Workflows

For more control:

/atomic-commit interactive - Same workflow, skill-level access
/atomic-commit sequence - Generate script to execute
Manual: Use /commit for each group after reviewing

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.
