# Canvas Skip `canvas-skip` is a result-producing manual handoff, not a lightweight homework solver. It may be selected for an unsupported delivery type, confirmed LockDown/proctored work, an in-person action, a user defer, missing required input, or a mutation-dependent task whose scoped authorization receipt is absent. ## Input contract Accept the exact item context from `canvas-execute`, including: - assignment and course identity/display labels; - due time and student-facing URL when present; - canonical stable ID-based work directory (`course-<course_id>__assignment-<assignment_id>`), never a mutable-name slug; - the reason execute selected `canvas-skip`; - whether the item should re-enter the next scan. Do not rescan Canvas or infer a different assignment from names. Do not invoke another course skill. ## Absolute no-action boundary - Do not solve, draft, research, download private assignment content, or create a fake deliverable. - Do not upload, submit, post a comment, or alter Canvas state. - Do not start, answer/save, complete, or retake a quiz. - Do not use browser automation to work around LockDown/proctoring. - Do not mark anything `draft_ready` or `submitted`. - A TODO, empty file, sentinel, skeleton, or placeholder is not a draft. ## Write an idempotent manual todo When a human next step is useful, append or update one entry in `runs/<today>/todo.md`. Use the assignment's stable local identity as the deduplication key so retries do not create dupli...
