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 | $0.00080 | $0.03725 |
| Opus 5 | $0.00040 | $0.01862 |
| Sonnet 5 | $0.00016 | $0.00745 |
| Haiku 4.5 | $0.00008 | $0.00373 |
Grade A, and why
copywriting-classic 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 13d 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 — 513 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Ogilvy Copywriting Principles

Methodology Foundation
Source: David Ogilvy - "Confessions of an Advertising Man" (1963) + "Ogilvy on Advertising" (1983)
Core Principles:
- "The consumer is not a moron. She is your wife. Don't insult her intelligence."
- "People don't buy the best products; they buy the products they can understand the fastest."
- "Tell the truth, but make the truth fascinating."
Ogilvy's Philosophy: Advertising must sell. Brand-building and direct response are not mutually exclusive. Great advertising gives facts, respects the reader, and creates personality—all while driving measurable results.

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.
