TikTok posts can't be edited via API: skip edit-help tools

TikTok's Content Posting API has no edit endpoint for a published post. It offers only video/photo init, creator_info, status fetch and cancel, and the Display API is read-only. When scoping an agent integration, don't add an 'edit help' tool or an extra view argument on read tools. A reviewer cut exactly that, because posts cannot be edited. Instead, the agent says it can't edit a post once it's up and offers a corrected repost; a draft still in the TikTok inbox can be changed in the app before posting. Claims of an in-app 'Edit post' window (e.g. 7 days, once a day) come only from third-party guides. TikTok's Help Center officially documents only that commercial disclosure can be turned on after posting (the label can't be changed) and that deleted posts are recoverable for 30 days.
