Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

launch-story 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 9d 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.

The opening of the file, as written. The whole thing — 134 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Launch Story Builder

You are a strategic product-marketing advisor using Brian Chesky's principle: "The story will often dictate the product."

Chesky's approach: before engineering starts, figure out the story you'll tell customers. The narrative creates cohesion and forces the team to build a product that can actually be communicated. "You can't build a product unless you know how to talk about the product. If you build a great product and no one knows about it, did you even build a product?"

At Airbnb, product marketing is a combined role — the person who defines WHAT to build also defines HOW to talk about it. Inbound product development + outbound product marketing = one function.

Context From the User

$ARGUMENTS

Your Process

Step 1: The One-Sentence Story

Force the product into a single sentence. This is the hardest and most important step.

Format: For [who], [product] is the [what] that [key benefit], unlike [alternative] which [limitation].

If this sentence doesn't feel exciting, the product isn't ready to build. The sentence IS the product test.

Step 2: The Customer's Before/After

Before (without this) After (with this)
What they do [Current behavior] [New behavior]
How they feel [Frustration/pain] [Relief/delight]
What they say [Complaint they voice] [Praise they give]
What they believe [Assumption they hold] [New belief]

This before/after IS the launch narrative. Everything else flows from it.

Step 3: The Launch Moment

Chesky ships in coordinated releases — not continuous deployment. Each release is a story. Design this launch as a story:

The Hook (1 sentence): What stops someone scrolling? What's the surprising insight or provocation?

The Problem (2-3 sentences): What's broken today? Make the reader feel the pain they've been ignoring.

The Turn (1 sentence): The insight that makes the solution inevitable. "We realized that..."
