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 | $0.00107 | $0.02429 |
| Opus 5 | $0.00053 | $0.01215 |
| Sonnet 5 | $0.00021 | $0.00486 |
| Haiku 4.5 | $0.00011 | $0.00243 |
Grade A, and why
purple-cow-audit 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.
This is a copy
100% identical to purple-cow-audit — 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.

Purple Cow Audit
Quality gate for affiliate marketers: score a product's remarkability 1-10 before promoting it. Based on Seth Godin's Purple Cow — if the product isn't remarkable, no amount of marketing skill will make it convert sustainably. The key question: "Would I recommend this to a friend WITHOUT earning a commission?"
Stage
S1: Research — Evaluating a program's worthiness IS part of research and discovery. This is a quality gate before you invest time creating content, landing pages, and email sequences.
When to Use
- User is considering promoting a specific product
- User asks "is this product worth promoting?"
- User wants to evaluate product quality before investing time
- User says "purple cow", "remarkable", "audit", "evaluate", "quality check"
- Before investing time in S2-S5 skills for a specific product
- User has a list of programs from
affiliate-program-searchand needs to pick the best
Input Schema
product: # REQUIRED
name: string # Product name
url: string # Product website
description: string # OPTIONAL — what it does
reward_value: string # OPTIONAL — commission rate
tags: string[] # OPTIONAL — categories
comparison_products: string[] # OPTIONAL — competitors to compare against
# Default: auto-discovered
Chaining from S1 affiliate-program-search: If run, evaluate the recommended_program.
Workflow
Step 1: Research the Product
web_search:"[product] review 2024 2025"— find recent reviewsweb_search:"[product] vs" OR "[product] alternative"— find competitorsweb_search:"[product] complaints" OR "[product] problems"— find issues- Check product website for: pricing transparency, unique features, social proof
Step 2: Score Remarkability
Rate each dimension 1-10:
| Dimension | Question | Weight |
|---|---|---|
| Uniqueness | Does it do something no competitor does? | 20% |
| Quality | Is it genuinely excellent at its core job? | 20% |
| Story | Does using it make you feel/look different? | 15% |
| Word of mouth | Would users tell friends unprompted? | 15% |
| Design | Is the experience delightful, not just functional? | 10% |
| Problem fit | Does it solve a real, painful problem? | 10% |
| Trust | Transparent pricing, good support, real social proof? | 10% |
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.
