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.

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 | $0.00067 | $0.00767 |
| Opus 5 | $0.00034 | $0.00383 |
| Sonnet 5 | $0.00013 | $0.00153 |
| Haiku 4.5 | $0.00007 | $0.00077 |
Grade A, and why
display-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 8d 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.

Paid Ads: Display / Banner
Guides display advertising: ad networks, banner ads, and programmatic buying. Use when placing ads on publisher sites (websites, apps) for brand awareness or retargeting.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
What Is Display / Banner
- Ad networks: Aggregate inventory from many publishers; buy placements programmatically or via direct deals
- Banner ads: IAB standard sizes (300×250, 728×90, 160×600, 320×50 mobile); static or animated
- Programmatic: Automated buying via DSPs; real-time bidding (RTB); audience targeting
Formats
| Format | Use |
|---|---|
| Display banner | IAB sizes; CPM or CPC; brand, retargeting |
| Native | Blends with page content; higher engagement |
| Video pre-roll | Pre-roll on publisher video; see ctv-ads for streaming |
| Rich media | HTML5; expandable, interactive |
| Mobile interstitial | Full-screen between content |
Buying Options
| Option | Use |
|---|---|
| Google Display | Part of Google Ads; automated placements; retargeting |
| Programmatic DSP | The Trade Desk, Magnite, etc.; audience-based; scale |
| Direct publisher | Deal with specific site; guaranteed placement |
| Ad network | Network aggregates inventory; simpler than full programmatic |
Metrics
| Metric | Use |
|---|---|
| CPM | Cost per thousand impressions |
| CPC | Cost per click |
| CTR | Click-through rate; typically low for banners (0.1–0.5%) |
| Viewability | % of impressions actually seen |
| Completion rate | For video; % who watch full ad |
Creative
- IAB sizes: 300×250 (medium rectangle), 728×90 (leaderboard), 160×600 (skyscraper), 320×50 (mobile)
- File types: Static image, animated GIF, HTML5
- Message: Clear CTA; minimal text; brand visible in 3 seconds
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.
