walkthrough-pr

Produce one continuous, readable PR review the user can read top-to-bottom. Same shape as walkthrough, plus a much heavier scrutiny pass. The user can have uncommitted changes in their main working tree — this skill never touches it.

Resolve scope

Arguments: <pr-branch> [dest-branch]. pr-branch is required.

Resolve pr-branch:

1. Try git rev-parse --verify <pr-branch>.
2. If that fails, run git fetch once, then retry as <pr-branch> and origin/<pr-branch>. Use whichever resolves.
3. If still unresolved, stop and ask the user.

Resolve dest-branch:

• If passed explicitly, use it (resolve same way as pr-branch).
• Otherwise, run git symbolic-ref refs/remotes/origin/HEAD (yields refs/remotes/origin/<name>).
• If that fails (origin/HEAD not set), stop and ask the user. Do not guess main / master / develop — better to ask than review against the wrong base.
