A writing guide for creating paid advertising text on Google, Meta, LinkedIn, and TikTok. It covers ad ideas, performance reviews, and A/B test plans.

Use it to write or improve search-ad headlines, descriptions, and other paid-social ad copy.

It helps you fit messages to each platform, audience, campaign goal, offer, and character limit instead of writing one generic ad.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00027	$0.02847
Opus 5.5	$0.00011	$0.01139
Sonnet 5.5	$0.00005	$0.00569
Haiku 4.5	$0.00003	$0.00285

Security

Grade B, and why

ad-copy scanned grade B with 1 finding 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 2mo 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.

Strips warnings and disclaimersmediumAnti-refusal

Omitting safety caveats hides risk from the user and is a common jailbreak preamble.

- [ ] No prohibited claims (income guarantees, health claims without disclaimers, etc.)

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.
