Difit

Ask the user for a code review by opening the changes in difit, a local diff viewer. Explicit opt-in only — use when the user names difit, asks to open or show the diff in the viewer, or has a standing instruction to request reviews through difit after changes. Do not use it for ordinary requests to review code, diffs, commits, branches, or pull requests.

Review a specific diff (branch, commit, or GitHub PR) and show the findings as comments inside difit, the local diff viewer. Explicit opt-in only — use when the user explicitly names difit, asks to open or annotate the review in the difit viewer, or invokes this skill by name. For ordinary requests to review code, diffs, commits, branches, or pull requests, review normally and respond in the conversation without launching difit.
