CLAUDE.md – JJ Quick Command List
A concise cheat sheet for essential Jujutsu (`jj`) version control commands, designed to help AI agents or users quickly perform common repository operations.
About this skill
This AI agent skill provides a streamlined reference for the most frequently used Jujutsu (`jj`) version control commands. It functions as a quick-access cheat sheet, enabling AI agents to efficiently navigate and manipulate `jj` repositories. The skill outlines key operations such as viewing changes, browsing history, starting new changes, committing messages, splitting commits, and managing branches, all within the context of Jujutsu's unique workflow. The primary goal is to empower AI agents to interact with `jj` repositories without needing to parse extensive documentation. By presenting commands alongside their purposes and descriptions, the skill simplifies the agent's task of translating user requests into appropriate `jj` actions. This is particularly useful for automated code management, development tasks, or even teaching users how to interact with `jj` via an AI assistant. Users or agents leveraging this skill can quickly identify the correct `jj` command for common tasks like checking repository status, creating new commits, undoing operations, or pushing changes. It focuses on the practical, day-to-day operations that are most crucial for efficient software development workflows.
Best use case
The primary use case is to enable AI agents to effectively manage code within Jujutsu (`jj`) version control repositories. Developers and teams using `jj` can benefit by integrating this skill into their AI-powered coding assistants, allowing the AI to assist with commit management, history browsing, and synchronization without direct manual command input. This skill bridges the gap between natural language requests and specific `jj` command executions.
A concise cheat sheet for essential Jujutsu (`jj`) version control commands, designed to help AI agents or users quickly perform common repository operations.
An AI agent will accurately identify and provide or execute the correct Jujutsu (`jj`) commands to fulfill common version control requests.
Practical example
Example input
Hey Claude, I've made some changes. How can I see what files I've modified and what the current commit is in my `jj` repository?
Example output
`jj status` will show you the working-copy commit and any staged/unstaged file modifications. (Or, if the agent can execute: "Running `jj status`... [output of jj status]")
When to use this skill
- When an AI agent needs to perform common version control operations in a `jj` repository.
- To quickly look up the syntax and purpose of essential `jj` commands.
- For automating routine `jj` tasks or generating `jj` commands based on user prompts.
- To assist new `jj` users or agents unfamiliar with the tool's specific commands.
When not to use this skill
- When working with Git-only repositories where `jj` is not installed or configured.
- For highly complex or niche `jj` operations not covered by the quick command list.
- When an agent needs deep conceptual understanding or advanced debugging of `jj` internals.
- If the user prefers to manually execute all `jj` commands directly.

# CLAUDE.md – JJ Quick Command List
A minimal cheat‑sheet of the day‑to‑day **Jujutsu (`jj`)** commands you (or an agent) really need.
| Purpose | Command | What it does |
| ----------------------------- | -------------------------------------- | ----------------------------------------------------------------- |
| **See changes** | `jj status` | Show working‑copy commit and staged/unstaged file modifications |
| **Browse history** | `jj log` | One‑line graph of commits; add `-r : --git` to include Git hashes |
| **Diff current work** | `jj diff` | Compare working‑copy commit to its parent (like `git diff`) |
| **Start a new change** | `jj new` | Fork a fresh change from `@` (no checkout dance) |
| **Write/update message** | `jj describe -m "msg"` | Sets commit message of the working change |
| **Split hunks interactively** | `jj split` | Launches diff‑editor to carve current change into smaller ones |
| **Undo last (or any) op** | `jj undo` | Reverts the specified operation in the op‑log |
| **List operations** | `jj op log` | Shows numbered operation history for quick undo/restore |
| **Push** | `git push origin @` *or* `jj git push` | Uses standard Git remotes; your CI never notices |
| **Pull / rebase** | `git pull --rebase` | JJ auto‑rebases local changes on fetch |
| **List branches (bookmarks)** | `jj branch list` | Display bookmarks pointing at changes |
| **Create branch** | `jj branch create feature` | Label current change as *feature* |
| **Move branch** | `jj branch set feature REV` | Point bookmark *feature* at another revision |
| **Delete branch** | `jj branch delete feature` | Remove bookmark label |
### Safety net
* `jj op restore <op‑id>` — time‑travel repo back to any previous operation (and still `jj undo` later)
* Everything is undoable; when in doubt, run `jj op log` followed by `jj undo`.
### Automation tips
* Pass `--no-editor` on `describe`, `split`, etc., in headless scripts.
* Prefer `--template '{id} {description|escape_json}\n'` for JSON‑friendly output.

claude-code-dispatch
Dispatch development tasks to Claude Code with automatic callback on completion. Supports Agent Teams (multi-agent parallel dev with dedicated Testing Agent), cost controls (--max-budget-usd), model fallback, git worktree isolation, custom subagents via --agents JSON, and MCP server integration. Use when: (1) dispatching a coding task to Claude Code and wanting automatic Telegram notification on completion, (2) running Agent Teams for parallel dev+test workflows, (3) needing zero-polling task execution with Stop Hook callback, (4) the user says 'use Claude Code to build/develop/create X', (5) the user asks to dispatch or run a Claude Code task. THIS IS THE DEFAULT for any 'build/develop/create a project' request — prefer this over claude-code-clawdbot for anything that takes >2 min or needs background execution.
