Build a Content Batching and Scheduling System

Act as a content productivity and systems coach. I want to batch-create and schedule my content so I am not writing posts day-to-day. I post on [PLATFORMS] with a frequency of [POSTING_FREQUENCY]. My content type is [CONTENT_TYPE]. Design a content batching system covering: the ideal batching session length and frequency (e.g. 2 hours every Sunday), the preparation steps before a batching session (idea bank, prompts, structure), a batching session agenda that produces [NUMBER] posts in one sitting, the tools to use for scheduling across my platforms, how to maintain content freshness when posts are pre-written, and how to leave space for reactive or timely content.
