I built a small agent that drafts replies to Instagram Reel comments with Claude Haiku and posts them only after approval. Writing it took nine pull requests. Connecting my account to the Instagram API, plus one extra account to test with, took longer: a disabled account, errors that said "not available" or "wrong password" when they meant "too many attempts", and two Meta app settings that turn every comment into an empty list.
