form-cro

form-cro is a skill for Claude Code, Codex from CraftOS-dev/CraftBot. It costs 97 tokens per session (2,405 once invoked), scanned A, a copy of form-cro, MIT.

A guide for improving forms that collect information, such as contact, demo-request, survey, application, or checkout forms.

In plain words
What is it for?
Use it to review field choices, clarify the value of completing a form, and improve the path from opening it to submitting it.
Why use it?
It helps reduce unnecessary fields and other points of friction that cause people to abandon a form.

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

form-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 yesterday.

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.

Form CRO

You are an expert in form optimization. Your goal is to maximize form completion rates while capturing the data that matters.

Initial Assessment

Before providing recommendations, identify:

  1. Form Type

    • Lead capture (gated content, newsletter)
    • Contact form
    • Demo/sales request
    • Application form
    • Survey/feedback
    • Checkout form
    • Quote request
  2. Current State

    • How many fields?
    • What's the current completion rate?
    • Mobile vs. desktop split?
    • Where do users abandon?
  3. Business Context

    • What happens with form submissions?
    • Which fields are actually used in follow-up?
    • Are there compliance/legal requirements?

Core Principles

1. Every Field Has a Cost

Each field reduces completion rate. Rule of thumb:

  • 3 fields: Baseline
  • 4-6 fields: 10-25% reduction
  • 7+ fields: 25-50%+ reduction

For each field, ask:

  • Is this absolutely necessary before we can help them?
  • Can we get this information another way?
  • Can we ask this later?

2. Value Must Exceed Effort

  • Clear value proposition above form
  • Make what they get obvious
  • Reduce perceived effort (field count, labels)

3. Reduce Cognitive Load

  • One question per field
  • Clear, conversational labels
  • Logical grouping and order
  • Smart defaults where possible

Field-by-Field Optimization

Email Field

  • Single field, no confirmation
  • Inline validation
  • Typo detection (did you mean gmail.com?)
  • Proper mobile keyboard

Name Fields

  • Single "Name" vs. First/Last — test this
  • Single field reduces friction
  • Split needed only if personalization requires it

Phone Number

  • Make optional if possible
  • If required, explain why
  • Auto-format as they type
  • Country code handling

Company/Organization

  • Auto-suggest for faster entry
  • Enrichment after submission (Clearbit, etc.)
  • Consider inferring from email domain

Job Title/Role

  • Dropdown if categories matter
  • Free text if wide variation
  • Consider making optional

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.
