What Git Catchup is

Git Catchup is a slash command published in the athola/claude-night-market repository on GitHub, which has about 339 stars. The repository describes itself as: “23 Claude Code plugins: TDD enforcement hooks, git/PR workflows, spec-driven development, code review, project lifecycle, fix-from-error, maintenance automation, context optimization, research, and multi-LLM delegation. 186 skills, 128 commands, 54 agents.”

A slash command is a reusable prompt saved as a markdown file and run by typing its name after a slash. In Claude Code, custom commands have been merged into skills: a file in .claude/commands/ and a skill folder in .claude/skills/ both create the same kind of command, and existing command files keep working.

Git Catchup gives you a repeatable way to run the same instructions without retyping them, optionally with arguments.

How to install Git Catchup

Claude Code

Download git-catchup.md from the repository.
Save it to ~/.claude/commands/ (all projects) or .claude/commands/ (one project). As a skill, you can instead save it as ~/.claude/skills/<name>/SKILL.md.
Run it by typing / followed by its name.

Claude Cowork

Turn the command into a skill: create a folder with the file saved as SKILL.md and zip it.
In Customize → Skills, click +, then upload the ZIP.
Run it from any task with / and the skill name.

New to extending Cowork? Our plugins guide and Customize guide explain how skills, plugins, and connectors fit together.

Inside the source file

An excerpt from plugins/sanctum/commands/git-catchup.md, shared under the repository's MIT license. Read the full file on GitHub.

To review changes, load the required skills in order:

Run Skill(sanctum:git-workspace-review) to capture the Git repository context (branch, status, diffs).
Run Skill(imbue:catchup) and work through its TodoWrite items (context confirmed, delta captured, insights extracted, follow-ups recorded).

Methodology

The imbue catchup methodology applies to Git contexts as follows:

Context Confirmation:

pwd confirms the repository location.
git status -sb shows the branch and working tree state.
git rev-parse --abbrev-ref --symbolic-full-name @{u} identifies the upstream branch.

Delta Capture:

git diff --stat ${BASE}...HEAD for change metrics.
git diff --name-only ${BASE}...HEAD for a file list.
Prioritize source, configuration, and documentation files; skip cache and build outputs.

Insight Extraction:

For each modified file, summarize the what, why, and any implications.
Use rg -n for targeted searches.
Defer deep analysis to specialized skills.

Follow-up Recording:

Record tests to run, documentation to update, or reviewers to notify.
Note any blockers that impede progress.

Manual Execution

If skills cannot be loaded, run these commands manually:

pwd
git status -sb
git diff --stat main...HEAD  # Or an appropriate base
git diff --name-only main...HEAD

For each important file:

Summarize what changed, why, and the implications.
Note any tests needed or documentation to update.

Close with an overall summary and any follow-ups.

Before you install

Read the whole file first. Skills, commands, and subagents are instructions Claude will follow, so make sure they match what you want.
Check which tools, scripts, or MCP servers it uses. Local servers and scripts run with your permissions.
Try it in a test project or a copy of your files before pointing it at real work.
Pin the version you tested, and review changes before updating.
Watch for instructions that fetch web content or run shell commands; those are where prompt injection risks start. See our prompt injection guide.
