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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00088 | $0.00786 |
| Opus 5.5 | $0.00035 | $0.00314 |
| Sonnet 5.5 | $0.00018 | $0.00157 |
| Haiku 4.5 | $0.00009 | $0.00079 |
Grade A, and why
page-cro scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Page CRO
Optimize landing pages and product pages for "$ARGUMENTS". Analyze current conversion performance and recommend improvements to increase conversion rate.
Arguments. $ARGUMENTS may contain the project name and optional flags. Take the first token as <project> and treat --skip-checks as a flag; never include flags in file paths. All paths below use <project>. If --skip-checks is present, skip the prerequisite check and, before writing any artifact, append one line to .metapowers/marketing/<project>/skip-log.md: - <ISO timestamp> — <skill name> skipped prerequisite check for <artifact file> — reason: <reason or "none given">.
Prerequisites
Read .metapowers/marketing/<project>/00-strategy.md. If this file does not exist, tell the user:
Phase 0 (Strategy) has not been completed for "". Run
/marketing:customer-research <project>first, or use--skip-checksto bypass.
Process
-
Read context:
- Read
.metapowers/marketing/<project>/00-strategy.mdfor audience and positioning - Read
.metapowers/marketing/<project>/02-act.mdif it exists
- Read
-
Page audit (if URL provided):
- Use WebFetch to analyze the page
- Evaluate: headline clarity, value proposition visibility, CTA prominence, social proof, objection handling
- Check page speed and mobile experience
- Identify friction points in the conversion path
-
Analyze page structure:
- Above-the-fold content: does it answer "what, who, why"?
- Information hierarchy: is the most important content most prominent?
- Visual flow: does the eye naturally reach the CTA?
- Content length: appropriate for the decision complexity?
-
CRO recommendations:
- Headline and subheadline improvements
- CTA placement, copy, and design recommendations
- Social proof placement and type
- Objection handling and FAQ placement
- Trust signals (security badges, guarantees, testimonials)
- Page speed and technical improvements
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.

page-cro is a skill published in the GitHub repository bromso/metapowers (2 stars, last pushed 3d ago), licensed MIT. It adds 88 tokens to every session and 786 once invoked, about $0.0004 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 2026-10-21.
