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 | $0.00051 | $0.03487 |
| Opus 5 | $0.00026 | $0.01743 |
| Sonnet 5 | $0.00010 | $0.00697 |
| Haiku 4.5 | $0.00005 | $0.00349 |
Grade A, and why
ad-copy-google-ads 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 10d 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.

Domain Knowledge
Character Limits — The Non-Negotiable Numbers
- Headlines: 30 characters (aim for 25-30; under 20 wastes space)
- Descriptions: 90 characters (aim for 75-90; under 60 is underutilized)
- Sitelink text: 25 characters
- Sitelink descriptions: 35 characters each (2 lines)
- Callouts: 25 characters
- Structured snippet values: 25 characters
- DKI default text + syntax overhead: the longest keyword in the ad group +
{KeyWord:}wrapper must fit within the 30-char headline limit. Count the literal longest keyword, not the default.
Quality Score — The Three Levers
Quality Score = Expected CTR + Ad Relevance + Landing Page Experience. Each is rated Above Average / Average / Below Average. The critical insight: these are relative to other advertisers bidding on the same keyword, not absolute metrics.
- Expected CTR: Driven by headline specificity, numbers, and strong CTAs. Generic headlines ("Best Service Available") kill CTR.
- Ad Relevance: The target keyword's core intent must appear semantically in the ad copy — not just keyword-stuffed, but meaningfully addressed. If the keyword is "emergency plumber near me," the ad must signal immediacy and locality, not just contain those words.
- Landing Page Experience: The ad's promise must be fulfilled on the landing page. If the ad says "Free Quote in 60 Seconds," the landing page must have a visible, fast quote form — not a generic homepage.
DKI — The Traps Nobody Warns About
{KeyWord:Default Text} capitalization variants: {keyword:} = lowercase, {Keyword:} = title case first word, {KeyWord:} = title case all words, {KEYWORD:} = ALL CAPS. The default text must itself be compelling ad copy, not placeholder garbage like "Our Product." Always calculate: longest keyword in the ad group + any static text in that headline ≤ 30 chars. Risky keywords for DKI: competitor brand names (trademark violations), misspellings, long-tail queries that read awkwardly as headlines, anything with "cheap" or "free" that could misrepresent the offer.
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.

ad-copy-google-ads is a skill published in the GitHub repository edholofy/dojo.md (9 stars, last pushed 4mo ago), licensed MIT. It adds 51 tokens to every session and 3,487 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
