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.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00063 | $0.00988 |
| Opus 5.5 | $0.00025 | $0.00395 |
| Sonnet 5.5 | $0.00013 | $0.00198 |
| Haiku 4.5 | $0.00006 | $0.00099 |
Grade A, and why
styling-mcp-setup 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.

@ama-styling/mcp Server Setup
Configure the @ama-styling/mcp server so AI assistants can discover, list, and recommend design tokens from your project's token library instead of guessing or hardcoding values.
Prerequisites
- A
styling.metadata.jsonfile generated by@ama-styling/style-dictionaryusing theama/json/metadataformat. - Node.js (LTS recommended) for running
npx.
Generating the Metadata File
The MCP server reads a styling.metadata.json that contains all your design tokens with their metadata, values, and Otter extensions. To generate it:
-
Install @ama-styling/style-dictionary, which provides the Ama transforms
npm install --save-dev @ama-styling/style-dictionary -
Add the
ama/json/metadataformat to your Style Dictionary config (sd.config.jsorstyle-dictionary.config.json):export default { source: ['tokens/**/*.json'], platforms: { metadata: { transformGroup: 'ama/css', buildPath: './', files: [{ destination: 'styling.metadata.json', format: 'ama/json/metadata' }] } } }; -
Build the tokens:
npx style-dictionary buildThis produces
styling.metadata.jsonat the project root.
Configuration
The server runs via npx with no permanent install required.
Claude Code
Add to .mcp.json at the project root:
{
"mcpServers": {
"ama-styling": {
"command": "npx",
"args": ["-y", "-p", "@ama-styling/mcp", "ama-styling-mcp-start", "--metadata", "./styling.metadata.json"]
}
}
}
GitHub Copilot (VS Code)
Add to .vscode/mcp.json:
{
"servers": {
"ama-styling": {
"type": "stdio",
"command": "npx",
"args": ["-y", "-p", "@ama-styling/mcp", "ama-styling-mcp-start", "--metadata", "./styling.metadata.json"]
}
}
}
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.

styling-mcp-setup is a skill published in the GitHub repository AmadeusITGroup/otter (59 stars, last pushed yesterday), licensed BSD-3-Clause. It adds 63 tokens to every session and 988 once invoked, about $0.0003 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 2026-08-30.
