Execute: Implement from Plan

Plan to Execute

Read plan file: $ARGUMENTS

Before you start — work on a feature branch

A ticket gets built on its own branch, so it can become one PR. Ideally you're already on that branch — cut it before planning — so the plan commit you made is on it and rides into the PR; a plan committed on the base branch won't be in this branch's PR. If you're still on base, this step creates the branch now. Detect the base branch (don't hardcode main): git symbolic-ref refs/remotes/origin/HEAD 2>/dev/null | sed 's@^refs/remotes/origin/@@' (fallback main).

• On the base branch, clean → create one: git checkout -b feature/<plan-slug>.
• Already on a feature branch or in a worktree → use it.
• On the base branch with uncommitted changes → STOP: commit or stash first.

(One branch per ticket is also what makes parallel worktrees clean later.)
