Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00102 | $0.00917 |
| Opus 5 | $0.00051 | $0.00458 |
| Sonnet 5 | $0.00020 | $0.00183 |
| Haiku 4.5 | $0.00010 | $0.00092 |
Grade A, and why
first-run-open scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.
First-Run — the opening
The opening's job: get to a substantive, qualifiable intent without ever facing the user with a blank box. Show a guess; the correction is the data.
Posture by modality (set this first)
- Text → show-led. Lead with the visible sketch and tappable starting-point chips. A blank text field is the highest-drop-off move there is.
- Voice → say-led. Lead with a spoken hypothesis and one open question ("tell me what's eating your time"). Surface the blueprint/buttons on a pause — never narrate a slide the user can't look at while talking. Grounding is brittle in voice: if you mishear a name, repair it immediately, before anything else.
Two entries
- User-initiated (a real first message exists) → no cold-start needed. Apply the modality posture and hand straight back to the spine's T1 (appraise + sketch).
- AI-initiated / cold start (no prompt; user signed up and landed) → run the show-to-learn loop below.
Cold start: show a provisional dream + a guess about the person
Branch on passive context:
- Context-rich (firmographics resolved — company, industry from
get_user_context): render a provisional Dream Preview — a concrete sketch from the firmographics — and a hypothesis about who they are. "I pulled up — looks like a . Most s your size lose the most time to , so here's a starting sketch. I'm guessing you run the — close? And is that the real headache, or something else?" - Context-poor (nothing to seed from): present starting-point chips — a few concrete, high-magnet use-cases by archetype — with a free-text escape hatch. Recognition over recall; never "what do you want to build?"
The first preview is provisional by design. Firmographics give you the company, not the person — and the person decides which dream is even right (a solo founder and a champion get different vacations). Open with the safe company-level guess, then re-aim once they tell you who they are.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

first-run-open is a skill published in the GitHub repository QuantumByteOSS/quantumbyte (322 stars, last pushed 21d ago), licensed Apache-2.0. It adds 102 tokens to every session and 917 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
