MINIMAL: Art first, then no text before/between tool calls. After ALL ops succeed, print ONE celebratory pirate quip about forging another link in the plunder chain (<20 words, icon-loaded). Vary it each time.

Context

• Current branch: !git branch --show-current
• Remote branches: !git fetch origin --prune 2>/dev/null; git branch -r --list "origin/*" 2>/dev/null
• Local branches: !git branch --list

Your task

Create the next link in the chain. Chaining is purely branch movement — create the branch and nothing else. Do NOT check for changes, do NOT check git status, do NOT guard against a clean working tree. The branch gets created regardless of whether there are pending changes. Staging, committing, pushing, and PR creation are /ship's job.

Why chaining exists

Large features are hard to review in a single PR. Chaining breaks the work into sequential, reviewable snapshots: -a is the first chunk, -b builds on -a, and so on. Each chain branch gets its own PR (created by /ship), giving reviewers a focused diff. The developer stays on their working branch between chains.

Step 1: Resolve the naming base

The naming base is the original dock branch that all chain branches are named from. Resolve it:

1. Protected branch guard: if on main, master, dev, develop, release/*, or hotfix/* — stop. Tell the user chaining requires a working branch and suggest /dock or creating a feature branch first.

2. Resolve from chain branch: if the current branch ends in -[a-z] (single lowercase letter suffix) AND origin/{branch-without-suffix} exists as a remote branch, then the current branch is already a chain branch. Strip the suffix to get the naming base. If the stripped name also ends in -[a-z] with a matching remote, keep stripping until you reach the true base.

3. Otherwise: the current branch IS the naming base.

Step 2: Determine chain state

From the remote branches context above, find any that match origin/{naming-base}-[a-z] (the naming base followed by a hyphen and a single lowercase letter):

• If no chain branches exist: the next link is -a
• If -a exists: the next link is -b
• If -a through -c exist: the next link is -d
• And so on, up to -z (if all 26 are used, stop and tell the user the chain is full)

Step 3: Create the chain branch

1. If a local branch with the target name already exists (from a previous failed attempt), delete it first with git branch -D {naming-base}-{letter}
2. Create the chain branch: git switch -c {naming-base}-{letter}

The user is now on the new chain branch. All commits from the previous chain branch (or base) carry forward.

Step 4: Print quip

Print one celebratory quip mentioning the chain branch name. Remind the user to run /ship to ship.
