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 | $0.00053 | $0.03549 |
| Opus 5 | $0.00026 | $0.01775 |
| Sonnet 5 | $0.00011 | $0.00710 |
| Haiku 4.5 | $0.00005 | $0.00355 |
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 11d 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.

Google Ads Copywriting
Domain Knowledge
Character Limits (Memorize These)
| Element | Limit | Min Utilization Target |
|---|---|---|
| RSA Headline | 30 chars | 27+ chars (90%) |
| RSA Description | 90 chars | 83+ chars (92%) |
| Sitelink title | 25 chars | 22+ chars |
| Sitelink description | 35 chars | 31+ chars |
| Callout extension | 25 chars | 20+ chars |
| Structured snippet value | 25 chars | 20+ chars |
Word budgets for drafting (constraint-first method):
- 30 chars ≈ 5–6 words. Think in 5-word phrases.
- 90 chars ≈ 15–17 words. Think in 2 short sentences or 1 punchy sentence.
- 25 chars ≈ 4 words. Think in fragments.
- 35 chars ≈ 5–6 words.
Character Counting Traps
- Em dash (—) = count as 1 character in Google Ads interface, but verify platform behavior.
- Default rule when ambiguous: count special characters at their maximum possible byte length to avoid violations.
- Smart quotes (" ") vs straight quotes (" ') — use straight quotes; they're consistently 1 char.
- Spaces count. Pipes count. Ampersands count.
- Never trust your own manual count. Always recount each item letter-by-letter as a final gate. If you produce 15 headlines, recount all 15 individually at the end.
DKI Syntax & Rules
- Correct format:
{KeyWord:Default Text}— the entire token including braces must fit within 30 chars. - Capitalization variants:
{keyword:default}(lowercase),{Keyword:Default}(title case first word),{KeyWord:Default}(title case all words),{KEYWORD:DEFAULT}(all caps). - The default text appears when the triggering keyword is too long or unavailable. It must be compelling standalone copy, not a throwaway like "Click Here."
- Critical check: Take your longest keyword in the ad group and substitute it into the DKI slot. Does the full headline exceed 30 chars? If yes, shorten the default or restructure.
- DKI risks: competitor names inserting, misspelled queries appearing, grammatically broken sentences ("Buy Best Running Shoes Near Me Today"), sensitive/inappropriate terms.
- Always provide 2+ static non-DKI headline alternatives as safety variants.
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 (10 stars, last pushed 4mo ago), licensed MIT. It adds 53 tokens to every session and 3,549 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.
