@paulocastellano Yes, ready for review! The branch is rebased on v1.1.0 (also adapted the new repurpose caption tests to the raised YouTube description limit) and CI is fully green. |

changed the title
A per-channel meta.first_comment (≤2200, Instagram's comment limit) is
posted by FirstCommentPoster right after a successful publish — YouTube
via commentThreads.insert, Instagram via /{media}/comments. Failures
are logged and never fail the live post; Stories and in-review posts
get no comment. Connect flows request the comment scopes.
Reworked for the post_platforms-into-posts merge: the poster takes the
post itself and the rules use the prefix-parameterized meta keys.

Why
The classic "link in the first comment" trick isn't possible through TryPost: neither a YouTube Short nor an Instagram post can carry an automatic comment posted right after publishing — the spot where creators put the links a caption can't make clickable (Instagram) or wants to keep out of the description (YouTube).
What changed
meta.first_commentfor YouTube (commentThreads.insert, ≤ 10,000 but capped at 2,200 to share the field with Instagram) and Instagram (/{media_id}/comments;instagram_manage_commentsjoins the requested scopes — existing IG connections need one reconnect to pick it up).FirstCommentPosterthat catches everything and only logs: a failed comment must never fail a published post. Posts held in pending review (Google Business) get no comment.PostPlatformMetaRules, so the web editor, the REST API, and MCP all accept and persist it (fields without a rule there get silently stripped byvalidated()— covered by the meta persistence tests).Testing
FirstCommentPosterTest,YouTubePublisherTest,PostApiPlatformMetaTest,PostPlatformMetaToolTestpass. Battle-tested live: first comments posted on YouTube Shorts and Instagram.
