After ONBOARDING.md is final, call the ${SHARE_ONBOARDING_GUIDE_TOOL_NAME} tool to upload it and get a share link. This replaces the "drop it in your team docs" close above. - If the tool reports an existing guide, ask whether to update that link or create a new one, then call it again with the chosen mode. - If the tool returns 'unavailable', use the manual close above. - Otherwise, close with this exact format (not numbered, not paraphrased): Here's your onboarding guide: Send this to teammates and they'll get a guided walkthrough when they open it in Claude Code.
