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

lean-canvas 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 4d 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.

Lean Canvas

Overview

A one-page business model designed for early-stage startups by Ash Maurya (adapted from the Business Model Canvas). It replaces operational blocks (Key Partners, Key Resources, Key Activities, Customer Relationships) with startup-critical blocks (Problem, Solution, Key Metrics, Unfair Advantage). The goal is to capture your riskiest assumptions on a single sheet so you can invalidate them fast.

The 9 Blocks

1. Customer Segments

Who has the problem you are solving? Name a specific group, not a broad market. Identify the Early Adopters — the subset who feel the pain most acutely today and will tolerate an imperfect solution to get relief.

2. Problem

List the top 3 problems your customer segment faces. Under each problem, note the Existing Alternatives — what customers use today (spreadsheets, manual workarounds, a competitor, doing nothing). If there are no existing alternatives, the problem may not be urgent enough to pay to solve.

3. Unique Value Proposition (UVP)

A single, clear sentence that explains why your product is different and worth paying attention to. Write it for your early adopters, not the press. A UVP is not a tagline — it names the outcome the customer gets and, if possible, the timeframe or mechanism. Example: "Close your books in one hour, not one week."

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.
