batch-complete — Bulk Complete or Cancel Items

Close out a feature subtree, cancel an abandoned workstream, or clean up stale items in one operation. Handles gate checks, active-item warnings, and reports exactly what succeeded and what was skipped.

Step 1 — Identify Scope

Resolve $ARGUMENTS to a UUID via query_items search (operation="search", query=$ARGUMENTS, limit=5); if ambiguous, present matches via AskUserQuestion.

If $ARGUMENTS is empty, classify the request from conversation context:

• Feature subtree: user mentions completing "everything under" a named item → search for that item, use rootId
• Specific items: user lists names or IDs → collect each UUID, use itemIds
• Cleanup: user wants to clear old/stale items → search by status or title fragment, collect UUIDs, use itemIds

If scope still cannot be determined, ask via AskUserQuestion: "Which item (or items) do you want to complete? Provide a root UUID, a title fragment, or a list of item IDs."
