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 | $0.00068 | $0.00515 |
| Opus 5.5 | $0.00027 | $0.00206 |
| Sonnet 5.5 | $0.00014 | $0.00103 |
| Haiku 4.5 | $0.00007 | $0.00052 |
Grade A, and why
signup-flow-cro 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 2mo 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.
What it actually says
Signup Flow CRO Optimization Framework
Conversion optimization methodology for signup flows: low-friction form design, modern authentication (passkeys/WebAuthn + social with safe fallbacks), NIST-aligned password UX, privacy-respecting progressive profiling, and statistically disciplined A/B testing. Code samples are illustrative starting points — validate any uplift on your own funnel.
On the numbers in this skill: social-proof counts like "Join 50,000+ Users" in the templates are PLACEHOLDERS. Only display a count you can substantiate — inflated or fabricated figures are both an ethics problem and, in some jurisdictions, a deceptive-advertising one. Swap in your real number or remove the claim. This skill ships no universal conversion benchmarks; see "Do NOT ship a universal social-login number" below for why.

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.

signup-flow-cro is a skill published in the GitHub repository san-npm/skills-ws (4 stars, last pushed 1mo ago), licensed MIT. It adds 68 tokens to every session and 515 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-07.
