Retrospect External Babysitter Run

Analyse a babysitter run that lives in an external public repository, using the same lens as the in-repo /babysitter:retrospect command. Produce a written retrospective with concrete suggestions for the process author (or, if the insight generalizes, for the babysitter project itself).

When to use

• User names an external repo and asks for a retrospective.
• User asks "find a babysitter run to retrospect on" (combine with the catalog-babysitter-users skill to pick one).
• User asks "how are other people using babysitter processes? What do they get wrong?".

Prerequisites

• gh CLI authenticated.
• docs/repo-with-babysitter-processes.md exists (if not, run the catalog-babysitter-users skill first).
• A workspace directory where external repos can be shallow-cloned (default: /tmp/babysitter-retrospect/ or .a5c/tmp/external-runs/).
