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 | $0.00119 | $0.01421 |
| Opus 5.5 | $0.00048 | $0.00568 |
| Sonnet 5.5 | $0.00024 | $0.00284 |
| Haiku 4.5 | $0.00012 | $0.00142 |
Grade C, and why
prototype scanned grade C with 2 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.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Prototype scaffolding + review-overlay workflow
You are about to scaffold a brand-new Marmo prototype. A prototype is a
standalone Vite + React + Tailwind 4 + @marmoui/ui app that lives
outside the monorepo and ships to Netlify. The @marmoui/prototype-overlay
package is pre-wired into the starter so reviewers can sign in with Claude
and leave inline comments, and the owner can click an element, write a
prompt, and copy a payload (file + line + selector + prompt) to the
clipboard for paste into a local Claude Code session.
If the user just wants to add a UI component to an existing Marmo product
app, use the marmo-ui skill instead — not this one.
Required steps (in order)
1. Verify the MCP is fresh
mcp__marmo-ui__get_knowledge_version
If this errors, surface it. Don't fall back to guessing component APIs.
2. Confirm prerequisites
Run in parallel:
node --version(need ≥ 20)pnpm --version(need ≥ 9)netlify --version(suggestnpm i -g netlify-cliif missing)echo $NPM_TOKEN | head -c 4(must not be empty — required for GH Packages)echo $MARMO_PROTOTYPE_OAUTH_CLIENT_ID | head -c 4echo $MARMO_PROTOTYPE_COMMENTS_API | head -c 4
If either MARMO_PROTOTYPE_* env var is missing, print this and stop:
Set these once in your shell rc:
export MARMO_PROTOTYPE_COMMENTS_API="https://<proj>.supabase.co/functions/v1/comments-api" export MARMO_PROTOTYPE_OAUTH_CLIENT_ID="<from anthropic console>"Ask the Design Systems team for the current values.
3. Choose a target directory
Default: ~/Sites/marmo-prototype-<kebab-case-name-from-prompt>. If it
exists and contains anything, ask for an alternative.
4. Copy the starter
Source = apps/prototype-starter/ inside the mahmoudilyan/marmoui
monorepo. The user should have it cloned; if not, clone shallow:
git clone --depth 1 https://github.com/mahmoudilyan/marmoui /tmp/marmo-ui-template
cp -R /tmp/marmo-ui-template/apps/prototype-starter <target-dir>
rm -rf /tmp/marmo-ui-template
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.

prototype is a skill published in the GitHub repository mahmoudilyan/marmoui (19 stars, last pushed 3mo ago), licensed MIT. It adds 119 tokens to every session and 1,421 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it C with 2 findings (recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
