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 | $0.00097 | $0.02405 |
| Opus 5.5 | $0.00039 | $0.00962 |
| Sonnet 5.5 | $0.00019 | $0.00481 |
| Haiku 4.5 | $0.00010 | $0.00241 |
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 1mo 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 form-cro — 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.

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:
-
Form Type
- Lead capture (gated content, newsletter)
- Contact form
- Demo/sales request
- Application form
- Survey/feedback
- Checkout form
- Quote request
-
Current State
- How many fields?
- What's the current completion rate?
- Mobile vs. desktop split?
- Where do users abandon?
-
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.

form-cro is a skill published in the GitHub repository CraftOS-dev/CraftBot (399 stars, last pushed today), licensed MIT. It adds 97 tokens to every session and 2,405 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to form-cro, differing in 0 lines, and is treated as a copy.

Operational modes (quick/standard/deep) should be first-class skills, not hard-coded branching — each mode defines its own phases, priorities, and completion criteria.
