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 5.1 | $0.00103 | $0.02614 |
| Opus 5 | $0.00051 | $0.01307 |
| Sonnet 5 | $0.00021 | $0.00523 |
| Haiku 4.5 | $0.00010 | $0.00261 |
Grade A, and why
category-designer 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 8d 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.
This is a copy
100% identical to category-designer — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 250 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Category Designer
Define a new category where your recommended product wins by default. Instead of competing on existing criteria ("best AI video tool"), reframe the buying decision so your product IS the category ("the AI avatar platform for non-creators"). Category kings capture 76% of category economics — this is the strategic meta-skill that makes all downstream marketing easier.
Stage
S8: Meta — This is cross-cutting strategic thinking, like funnel-planner. It operates above individual skills and reframes the entire marketing approach. Use it before creating content, offers, or landing pages.
When to Use
- User is competing in a crowded market and needs to stand out
- User asks about "positioning", "category", "differentiation", "reframing"
- User says "category of one", "own a category", "change the game"
- After
monopoly-niche-finderto formalize the niche into a named category - After
purple-cow-auditto amplify what makes a product remarkable - Before creating content/offers to ensure consistent category messaging
Input Schema
product: object # REQUIRED — the product to position
name: string
description: string
key_features: string[]
pricing: string
current_category: string # What category it's currently in
# e.g., "AI video tools", "email marketing platforms"
competitors: string[] # OPTIONAL — main competitors
# Default: auto-researched
your_audience: string # OPTIONAL — your specific audience
# Default: inferred from product
monopoly_niche: string # OPTIONAL — from monopoly-niche-finder
# Default: none
Chaining from S1 monopoly-niche-finder: Use monopoly_niche.intersection as the starting point for category design.
Chaining from S1 purple-cow-audit: Use remarkable_angles to identify category-defining features.
Workflow
Step 1: Analyze Current Category
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.
