Token cost

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.

Security

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 9d 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.

Signup Flow CRO

Audit and optimize signup conversion funnels to maximize registration completions.


1. Signup Flow Audit Framework

When auditing a signup flow, evaluate each of these dimensions:

Number of Steps

Steps Benchmark Completion Rate Notes
1 (single page) 65-80% Best for simple products
2 50-65% Good balance of data collection and UX
3 35-50% Acceptable for complex products
4+ 20-35% Only if justified by product complexity

Rule of thumb: Every additional step loses 10-20% of users.

Audit questions:

  • Can any steps be combined?
  • Can any steps be deferred to post-signup?
  • Is every step necessary for the user to start getting value?

Form Fields

Fields Impact on Conversion
Email only Highest conversion (baseline)
Email + password -10-15% vs email only
Email + password + name -15-25% vs email only
5+ fields -30-50% vs email only

Audit questions:

  • Which fields are truly required at signup? (vs. collected later)
  • Can you use progressive profiling instead of upfront collection?
  • Are field labels clear and unambiguous?
  • Do fields use appropriate input types (email, tel, etc.)?
  • Are there unnecessary fields (phone, company size, "how did you hear about us")?

Social Login Options

Provider Typical Lift Best For
Google +15-25% B2B, SaaS, productivity tools
Apple +5-15% iOS-first products, privacy-conscious users
GitHub +10-20% Developer tools
Microsoft +5-15% Enterprise, Office-adjacent tools
Facebook +5-10% B2C, social products (declining trust)

Audit questions:

  • Are social login buttons prominent or buried?
  • Do social logins request minimal permissions?
  • Is there a fallback if social auth fails?

Progress Indicators

For multi-step flows, progress indicators reduce abandonment.

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.
