- Publish-ready X post or thread text with character-aware structure
- Optional specs noted for paired image or video agents

Journey fit
Launch distribution is where builders ship messaging to social channels; X copy is a canonical shelf for outbound posts rather than long-form site content. Distribution subphase covers platform-native post formats, threads, and engagement-length tuning specific to X.
How it compares
Use for X-native short copy and threads instead of repurposing generic chat marketing blurbs that ignore character and URL rules.
