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 | $0.00035 | $0.03538 |
| Opus 5.5 | $0.00014 | $0.01415 |
| Sonnet 5.5 | $0.00007 | $0.00708 |
| Haiku 4.5 | $0.00003 | $0.00354 |
Grade A, and why
cro-frameworks 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.

CRO Frameworks
When to Activate
Use this skill when starting a conversion rate optimization program, conducting a heuristic evaluation of a page or flow, prioritizing a backlog of optimization ideas, setting up a CRO testing process, auditing an existing page for conversion issues, or when asked to "improve conversion rates" or "run a CRO audit." This skill provides the strategic frameworks — pair it with landing-page-optimization and funnel-design for tactical execution.
First Questions
Before applying any CRO framework, clarify:
- What is being optimized? (specific page, flow, funnel, or entire site)
- What is the current conversion rate and what data exists? (analytics, heatmaps, session recordings)
- What is the traffic volume? (determines whether A/B testing is statistically viable)
- What tools are available? (analytics, heatmaps, A/B testing, session recording, surveys)
- Has any optimization been done before? (past tests, learnings, existing hypotheses)
- What is the business impact of a 1% conversion improvement? (ties CRO to revenue)
Core CRO Principle
Conversion is not a design problem, a copy problem, or a technical problem. It is a research problem. The best CRO programs are driven by systematic research that identifies what is preventing conversion, then uses structured experiments to remove those barriers. Guessing what to test is the most common CRO mistake.
Framework 1: LIFT Model (WiderFunnel)
The LIFT model evaluates six conversion factors that either help or hinder conversion.
The Six Factors
Value Proposition (the vehicle) The core driver of conversion. If the perceived value of converting doesn't exceed the perceived cost, nothing else matters.
- Is the value proposition clear within 5 seconds?
- Is it specific and quantified?
- Is it differentiated from alternatives?
- Does it match the visitor's awareness level?
Relevance (conversion driver) How well the page matches the visitor's intent and expectations.
- Does the content match the traffic source (message match)?
- Is the language appropriate for the audience?
- Are the examples and proof relevant to this segment?
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.

cro-frameworks is a skill published in the GitHub repository brainbytes-dev/everything-claude-marketing (10 stars, last pushed 7mo ago), licensed MIT. It adds 35 tokens to every session and 3,538 once invoked, about $0.0001 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 2026-09-03.
