create-branch

Productivity

Create a new git branch for a Jira ticket using the project's `<user>/<JIRA>-<slug>` naming convention, then transition the Jira ticket to "In Progress" via the `/jira start` flow. Works in the main checkout and inside an existing worktree.

Create Branch

Create a new git branch from develop and link the work to its Jira ticket by transitioning the ticket to In Progress in one step. All deterministic logic — branch-name building, ticket extraction, slugification — is in tools/jira/jira_cli.py. This SKILL.md just orchestrates.

Usage

/create-branch AND-1234 fix login crash
  # → branch: jdoe/AND-1234-fix-login-crash
  # → AND-1234 transitioned to In Progress

/create-branch AND-1234-fix-login-crash            # combined arg works too — ticket is auto-extracted, not duplicated in slug
/create-branch jdoe/AND-1234-fix-login-crash       # explicit full branch name (passthrough)
/create-branch AND-1234                             # description optional
/create-branch --no-jira AND-1234 some change      # skip the Jira transition
/create-branch --base main AND-1234 hotfix         # base off main, not develop
/create-branch --no-pull AND-1234 quick fix        # skip git fetch/pull of base

Arguments

Argument	Description
`<JIRA-ID>` `<desc>`	Jira key + optional description (multiple words allowed)
`<full-branch>`	A fully-qualified branch name containing `/` is used as-is
`--base <branch>`	Base branch (default: `develop`)
`--no-jira`	Skip the `/jira start` transition (still creates the branch)
`--no-pull`	Skip `git fetch && git pull` of the base before branching

Steps

Step 1 — Build the branch name

First strip this skill's own flags (--base <branch>, --no-jira, --no-pull) from the args — including the value that follows --base. Only the Jira key + the free-form description words should reach the CLI:

# e.g. user typed: --no-pull AND-1234 quick fix --base main
# pass ONLY:        AND-1234 quick fix
tools/jira/jira branch-name <ticket + description words>

This matters because branch-name slugifies whatever it receives. The CLI defensively drops any leftover ---prefixed token, but it cannot know that the bare main after a stripped --base is a flag value — so leaving --base main in would yield ...-main in the slug. Strip flags here.

It returns the full branch name (<prefix>/<TICKET>-<slug>) or exits 1 if no ticket could be parsed. Prefix comes from git config user.email's local part (jdoe@mega.co.nz → jdoe).

Some epics use a different branch convention (e.g. an extra component segment like <user>/<JIRA>-<component>NN-<desc>). The CLI does NOT know about those; if the ticket falls under such an epic, pass the full branch name as the first arg so the CLI hits its passthrough path.

Step 2 — Extract the Jira key (for Step 5)

tools/jira/jira branch-ticket

But that reads the current branch, not the new one. For /create-branch we already have the new args — extract the key from them with the same regex (AND-\d+, case-insensitive, first match). The CLI's branch-ticket is only useful after the branch has been created. If no key is found:

With --no-jira → continue (no Jira step will run).
Without --no-jira → halt and ask the user.

Step 3 — Detect worktree context

git rev-parse --is-inside-work-tree
git worktree list --porcelain

This skill does NOT create worktrees — that's EnterWorktree's job. It just branches in whatever checkout/worktree the user is in.

Step 4 — Refresh base + create branch

Unless --no-pull was passed:

git fetch origin
git checkout <base>          # default: develop
git pull --ff-only origin <base>

If git checkout fails because of uncommitted changes that would be overwritten, halt and surface the error. Do NOT discard the user's work.

Then:

git checkout -b <branch-name>

If the branch already exists, ask the user whether to switch to it or pick a different name. Do not force-overwrite.

Step 5 — Transition Jira ticket (skip if `--no-jira`)

Invoke the /jira start flow from .claude/skills/jira/SKILL.md. Pass the key explicitly. If transition fails, report the failure but do NOT roll back the branch — the branch was created successfully and the user can re-run /jira start <KEY> later.

Step 6 — Report

Branch created:   <branch-name>
Base:             <base>
Jira:             <KEY> → In Progress   (or: skipped / failed: <reason>)

Notes

This skill does not push the branch. Use /create-mr when ready.
This skill does not create worktrees. Use EnterWorktree first if you want isolation.
