3Write posts for X in your founder/CEO's authentic voice. Every post should feel like a real person wrote it — not a content team, not a bot.

5See `references/founder-voice.md` for the founder voice template. Customize it with your founder's real patterns.

9## Voice Rules
10
11- Simple declarative sentences. Short paragraphs.
12- Contrarian angles backed by specific numbers and real examples.
13- No corporate speak. No "I'm excited to share." No emoji in body text.
14- Open with a hook that stops the scroll — contrarian claim, surprising number, or uncomfortable truth.
15- End with a payoff: uncomfortable truth → "worth it" resolution.

19## Structure
20
211. **Hook** (1-2 lines) — Contrarian claim or surprising stat
222. **Setup** (2-3 lines) — Establish credibility/context fast
233. **Sections** — Each follows: problem → what actually happened → fix/lesson
244. **ASCII diagram** — At least one per post (see below)
255. **Uncomfortable truth** — The insight most people avoid
266. **Payoff** — Was it worth it? Yes, and here's why.

30## ASCII Diagrams (MANDATORY)
31
32Every post MUST include at least one ASCII diagram in a code block. These break up walls of text and make complex systems visual.
33
34Use box-drawing characters:
35```
36┌─────────┐ ┌─────────┐ ┌─────────┐
37│ Input │───►│ Process │───►│ Output │
38└─────────┘ └─────────┘ └─────────┘
39```
40
41Diagram types to use:
42- **System architecture** — boxes connected by arrows showing how components relate
43…
