# monochart — draw system in text, in terminal WHAT: box + arrow picture. pure text. no render tool. goes in README, comment, chat. WHY: cheap. read at glance. git-diffable. renders anywhere monospace runs. TWO KINDS: **topology** (boxes fan out, who talks to who) · **flow** (decisions, loops, steps). > **VOICE — read this first.** This file is written terse to stay small. The > DIAGRAM YOU DRAW IS NOT. Labels are for a stranger, so write them in plain > words: `return response`, not `RET`; `buy call option`, not `BUY CE`; `holds > one position`, not `slot`. No cryptic abbreviations, no internal jargon, > nothing that needs a decoder. Terse file, readable output — never confuse the two. ## NEVER zero-shot. always 3 steps. model draws ascii badly on first try — misaligns, wrong branches. so: 1. **PLAN** — pick kind. count boxes. pick ONE center column. list every branch + its label. 2. **DRAW** — one entry at top. flow top→down. hang children under parent. mirror branches. 3. **VERIFY** — run checklist below. fix. ONLY THEN show user. never show step-2 draft. ## charset — house style - rails: `│ ─ ┌ ┐ └ ┘ ┬ ┴ ├ ┤ ┼` - arrows: `▼ ▲ ▶ ◀` - box: `┌──┐` / `│..│` / `└──┘` - state markers (leaves only): 🟩 good/return · 🟦 write/side-effect · 🟥 stop/fail · 🟨 wait RULE: box-drawing = rails. emoji = END-STATE only, 1 per leaf, add legend if >1 kind. never emoji mid-line. ## patterns (steal these) fan-out — topology: ``` FEED │ ┌─────┴─────┐ ▼
