# Canvas Bootstrap Turn one student-selected recurring pattern into a durable Codex course skill. This is a detective and authoring workflow, not a pending-work scanner and not a submission workflow. Bootstrap is intentionally scope-first: one selected candidate, one course, one route per invocation. The student may run it again for another pattern later. ## Entry contract Normal first-run entry requires all of the following: 1. Canvas authentication has already been verified by `canvas-setup`. 2. `canvas-skill-opportunity` wrote the private local `runs/<today>/skill-opportunities.json` and companion Markdown report. 3. The student explicitly selected one numbered candidate in a later turn. The opportunity report is evidence, not authorization. A ranking does not authorize skill creation by itself, does not approve any pending assignment, and grants no upload, submission, or quiz-mutation authority. A manual redesign request may target one existing route without a fresh opportunity report, but Bootstrap must still run the same current-evidence and viability checks and must ask before replacing a working skill or private overlay. If invoked with no selected candidate and no explicit redesign target, stop and ask for the candidate number. Do not choose the top-ranked item for the student. ## Outputs and privacy split On a successful run, Bootstrap may create or update exactly these local surfaces: - `.agents/skills/canvas-<safe-name>/SKILL.md` — tracked, public-sa...
