Drafted the missing campaign in the house pattern, published a one-off now, scheduled the recurring copy for weekdays pre-market, and moved it a half hour to clear the mug post's slot. Your title edit came through on my next read.\"\u003c\/em\u003e\u003c\/p\u003e\u003c\/blockquote\u003e\n\n\u003cp\u003e\u003cstrong\u003eThat is an agent's work log from one morning in eXcalibur. The Marketing Department gained a junior copywriter, and the copywriter got a desk.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eeXcalibur gives your agent a real seat in your marketing operation: a shared library of posts and Snippets, a campaign calendar, a saved Voice, and the statistics to learn what worked. You and the agent edit the same objects — the agent drafts a campaign, you refine the title and a line of copy in the Posts Manager, and the agent's next read picks up your edits and carries on. Collaboration happens in the work itself.\u003c\/p\u003e\n\n\u003cp\u003ePosts are built from stored, reusable Snippets. Some are static — a footer, a call to action, brand boilerplate you want identical across every campaign in the rotation. Others are dynamic: a Snippet holds an agentic prompt, and when the scheduler comes due it resolves that prompt fresh and renders the answer in your saved Voice before publishing. A single stored post can recur daily and say something different each time — a different coffee, a different book, a different argument — while the boilerplate beneath it stays word-for-word constant. The Voice profile carries a list of banned constructions, so the phrases you never want said stay out of everything the agent drafts. Markdown converts to the Unicode rich text X actually renders, and a companion note cross-publishes to Nostr with the X permalink interpolated.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eThe calendar is an object your agent can reason about.\u003c\/strong\u003e It reads the whole schedule in one pull, notices two campaigns sharing the same half-hour slot, and nudges one into clear air. It publishes a one-off today while leaving the recurring template untouched for Monday. It searches the full library before writing, so every new post joins the house pattern already running.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAnd the numbers close the loop.\u003c\/strong\u003e Metrics snapshots accumulate on every published post, and reach scores span the whole corpus — so the agent studies which arguments traveled and lets the next draft learn from the last one's performance.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eYour X credentials stay in your custody.\u003c\/strong\u003e They travel by encrypted Nostr DM and never sit in your config.
