On-demand preparation of working-tree changes for commit by selectively formatting affected components. Use when explicitly requested outside the routine dough-execute-plan wrap-up; stop when a formatter result needs semantic or design judgment.

See how to installReview the instructions the agent will receive before you install.
Format the current working-tree changes without taking ownership of Git state. The repository command owns changed-component detection; do not reproduce its path-to-component mapping in this skill or in ad hoc shell logic.
This is an explicitly on-demand skill. Routine dough-execute-plan wrap-up runs the
same repository command directly and does not invoke this skill or spawn a
formatting agent.
From the repository root, record git status --short so the final report can
identify the changed paths present before formatting.
Run the selective formatter through the repository runner:
./scripts/run.sh pnpm format:changed
The command considers staged, unstaged, and nonignored untracked paths and formats only their affected components.
If the command reports a mechanically determined correction that it could not apply, make only that mechanical correction and rerun the command. Examples include formatter-prescribed whitespace, import ordering, or another result with one unambiguous non-behavioral fix.
If resolving a result could change behavior, public types, architecture, or design intent, stop without guessing. Preserve any formatting already applied and report the diagnostic and the judgment needed.
Record git status --short again and report every changed path remaining,
including paths added or modified during formatting.
Never stage, commit, push, revert, restore, stash, or hide changes. Do not run
format:all, duplicate component detection, or broaden the task beyond
mechanical formatting results.
On success, end the response with:
## FORMAT CHANGED COMPLETE
Include the command result and changed-path list immediately before the marker.
When judgment is required, include the failing diagnostic, changed-path list, and the decision needed, then end with:
## FORMAT CHANGED JIDOKA STOP
