Specialist agent role

Twitter/X Growth

An AI specialist agent that ships build-in-public threads in your founder voice every weekday morning. Drafts wait in your IM for review; you approve, edit, or reject before anything posts.

Schedule · Weekdays 8:00 AM (draft delivery) + ad-hoc when something material happens

Sample briefing

"48 days. 908 tests. Shipping v1 today. Thread of 6 tweets ready: opens with the milestone, walks through one technical detail (the SQLite-vec bundling fix from week 3), one product decision (why we cut the dashboard before v1), one customer quote, ends with the v1 link. Three CTAs A/B'd; pick one or skip."

What Twitter/X Growth does

  • Drafts a daily build-in-public thread in your voice — milestone, technical detail, product decision, customer quote, link
  • Reads your existing tweets + product docs + memory to lock onto your voice signature
  • Picks topics from real signals — your shipped commits, customer messages, product updates, competitor news
  • Suggests 3–5 alt CTAs per thread for you to pick (or skip)
  • Adapts tone — when your week was rough (failed deploys, churn), it does NOT auto-perform optimism
  • Maintains a per-tenant 'banned phrases' list so it never writes 'in today's fast-paced world' or other AI-fluff giveaways
  • Avoids posting cadence anti-patterns — no two consecutive milestone threads, no daily 'lessons learned' posts

How it works

Most indie founders know they should build in public. Most don't, because writing a daily thread costs 30–60 minutes that could go to shipping. Twitter/X Growth solves the cost, not the discipline — drafts arrive in your Slack at 8 AM; you spend 2 minutes reviewing and posting; the practice becomes sustainable.

Voice is the entire game. A thread that doesn't sound like you tanks your engagement and trains your audience to scroll past your handle. The role builds your voice profile from three sources: (1) your last 200 tweets, (2) your existing blog / podcast transcripts uploaded to the knowledge base, (3) your inline corrections on the first 5–10 drafts. By week 2 most customers report drafts that pass the "would I have written this?" test.

Topics from real signals, not generic templates. The role pulls draft topics from: your shipped commits this week (via GitHub if connected), customer messages you've thread-shared, product launches, competitor news flagged by the Research role, and long-form drafts from SEO Content (each cornerstone post can become 3–5 thread variants). It does NOT generate "5 lessons learned about productivity" filler.

Draft-only delivery. Nothing posts to your account without explicit approval. The role can't access your X credentials directly — it ships drafts to Slack with a one-click "post to X" button that opens X's compose view with the thread pre-filled. You always have a chance to edit or skip.

What Twitter/X Growth does not do

  • Auto-post to X without your approval — drafts only
  • Reply to other accounts on your behalf (engagement is yours)
  • Run paid X promotions or boost specific tweets
  • Write threads for accounts that aren't yours (no agency / multi-brand mode in Phase 1)
  • DM strangers (cold outreach is a separate role with stricter discipline — Cold Email Outbound)

FAQ

Can Ceres write build-in-public threads in my founder voice?
Yes. Ceres's Twitter/X Growth agent drafts a build-in-public thread every weekday — a milestone, one technical detail, one product decision, a customer quote, and a link — in your founder voice, learned from your existing tweets and product docs. Drafts arrive in your IM around 8 AM; you approve, edit, or skip. It never auto-posts to your X account.
Will threads sound like AI-generated slop?
Only if you let them. The role's voice profile builds from your real tweets — the more you correct in week 1, the faster it locks. The 'banned phrases' list catches AI tells ("in today's fast-paced world", "leverage", "synergize", "game-changer") before drafts ship. Most customers report week-3+ drafts pass blind tests with their followers.
What if I don't have a strong existing X account?
Bring 5–10 sample tweets / blog excerpts in your voice when onboarding. The role uses those as the seed; corrections in week 1 lock the voice. New accounts can use the role from day 1 — the cold-start is no worse than a human ghostwriter's.
Can it write reply-guy threads or engage with discourse?
It surfaces engagement-worthy threads in your IM as 'consider replying' notes (with a draft reply if you want one), but does NOT auto-post replies. Engagement is the part where founder authenticity matters most — we don't automate that.
What about LinkedIn?
LinkedIn B2B is a separate role with a different voice (more formal, longer-form, audience is buyers not peers). Both can be active — they share memory of your voice corrections so adjustments compound.
What if I want to take a week off (vacation, conference, deep-work sprint)?
Pause the role from the dashboard or just tell Ceres in your IM ("pause Twitter for a week"). Drafts stop landing in your IM until you resume. When you come back, the role catches up on the backlog of would-have-been topics from your shipped commits / customer messages / competitor news during the off-week — you don't lose context, just the continuous cadence.
