DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Ultrareview Auto-Fetches Missing Branches

When /code-review ultra or /review can't find the specified base branch, it now attempts to auto-fetch it from origin before failing. If fetch succeeds, the review proceeds without user intervention.

Details
  • Uses git ls-remote --heads origin <branch> to check existence, then git fetch ... refs/heads/<branch>:refs/remotes/origin/<branch>.
  • If the branch exists on origin but couldn't be fetched: "<branch>" exists on origin but couldn't be fetched. Run \git fetch origin <branch>\ and try again.
  • If the branch name looks like a typo, Claude now suggests the closest branch: "<name>" is not a branch in this repo. Did you mean \<suggestion>\?
  • Shallow clone detection: if fetch succeeds but no merge-base exists, suggests git fetch --unshallow origin.
Evidence

"exists on origin but couldn't be fetched. Run \git fetch origin" (search for "JI_"`)

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
