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 | $0.00092 | $0.00960 |
| Opus 5 | $0.00046 | $0.00480 |
| Sonnet 5 | $0.00018 | $0.00192 |
| Haiku 4.5 | $0.00009 | $0.00096 |
Grade A, and why
top-banner-generator 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 12d 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Components: Top Banner (Announcement Bar)
Guides top announcement bar and sticky banner design for conversion. Top banners answer visitor questions in ~3 seconds (trust, discount, free shipping, urgency) and can increase coupon redemption by 30-50% when used well.
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.
Initial Assessment
Check for project context first: If .claude/project-context.md or .cursor/project-context.md exists, read it for offers, messaging, and Section 12 (Visual Identity).
Identify:
- Goal: Lead capture, promo, urgency, trust, free shipping
- Placement: Above header (sticky) or below; dismissible or persistent
- Audience: All visitors vs segmented (geo, returning, cart abandoners)

| Student/education | "Students: 30% off today, 15% off ongoing" | education-program |
| Startups/education | "Startups: Special pricing — Apply now" | startups-page-generator |

| First-time | "New users: 20% off first year" | discount-marketing-strategy |

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.
