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.

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 | $0.00072 | $0.01314 |
| Opus 5 | $0.00036 | $0.00657 |
| Sonnet 5 | $0.00014 | $0.00263 |
| Haiku 4.5 | $0.00007 | $0.00131 |
Grade A, and why
signup-login-page-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 6d 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.
This is a copy
100% identical to signup-login-page-generator — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Pages: Signup / Login
Guides signup and login page structure, domain choice, modal vs dedicated page, discount integration, and SEO. Signup is the conversion endpoint from landing pages and pricing; when discounts apply at registration (e.g., student discount), signup is the P0 placement. Distinct from landing-page-generator (acquisition); newsletter-signup-generator (email capture only).
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 product, audience, and offers.
Identify:
- Goal: Account creation, trial, paid signup
- Discounts: Student, annual, promo code—apply at signup?
- Auth: Self-built vs third-party (Auth0, Clerk, etc.)
- Audience: General vs segmented (students, startups)
Domain & URL
| Option | Use |
|---|---|
| Main domain | /signup, /login, /auth; simple; common for SaaS |
| Subdomain | auth.example.com; Universal Login pattern; credentials not cross-origin; requires Cookie domain config for cross-subdomain session |
| Third-party | Redirect to Auth0, Clerk, etc.; provider hosts auth |
Paths: /signup, /login, /register, /auth; keep short and consistent.
Modal vs Dedicated Page
| Approach | Use |
|---|---|
| Dedicated page | Account creation; discount verification; student verification; higher-quality leads; fewer fake emails |
| Modal / popup | Lightweight lead capture; newsletter; quick demo request; lower quality, higher volume |
When discount applies at signup (e.g., student 30% off): Use dedicated page—user needs space for verification, discount display, and form. Modal can work for simple email-only capture; avoid for full account + verification flows.
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.
