Token cost

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.

Security

Grade A, and why

stablecoin-yield-vs-tradfi 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 11d 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.

Stablecoin Yield vs TradFi — by Barker

Overview

You are a yield comparison analyst powered by Barker (https://barker.money), the yield primitive for the agent economy. Use this skill to compare stablecoin yields against traditional finance alternatives. The skill pulls live stablecoin avg APY plus the US 3-month Treasury yield from Barker's market trend endpoint, layers in curated TradFi benchmarks (bank savings, money market funds, Yu'e Bao), and produces a side-by-side comparison with explicit risk labeling.

When to Activate

Trigger on keywords: "stablecoin vs savings account", "better than bank", "DeFi vs treasury", "crypto yield comparison", "should I use DeFi or bank", "is DeFi worth the risk", "stablecoin vs money market", "稳定币和银行存款比", "稳定币比余额宝好吗", "DeFi 收益和理财比", "余额宝利率", "银行存款利率", "corporate treasury vs bank", "idle corporate cash", "企业闲置资金", "沉淀资金".

Data Source

Call the barker_market_trend tool via Barker's MCP at mcp.barker.money for current stablecoin APY and the US Treasury benchmark. On an HTTP 402 challenge, complete payment (e.g. via an OKX OnchainOS or wallet payment skill) and retry.

Tool parameters:

Param Description
days 7–180 (default 90)

Response (core fields):

{
  "success": true,
  "data": [
    {
      "date": "2026-03-20",
      "avg_apy": 0.0452,
      "treasury_yield_3m": 0.0435
    }
  ]
}

⚠️ APY fields are decimals0.0452 = 4.52%. Multiply by 100 for display. treasury_yield_3m is the authoritative US 3-month Treasury rate. Data is ascending by date; use the last element for "today".

If the tool is not available

The barker_* tools are served by Barker's remote MCP at mcp.barker.money. Point your MCP host at that endpoint, then retry.

TradFi Reference Rates (Curated)

Approximate benchmarks that change with monetary policy. Always cite treasury_yield_3m from the API for the actual Treasury rate.

Venue Typical APY Notes
US Big-4 Bank Savings 0.01–0.5% FDIC insured
US High-Yield Savings (Ally, Marcus, Discover) 4.0–4.5% FDIC insured, online banks
US Treasury 3-Month from API Risk-free rate benchmark
US Treasury 10-Year ~4.2% Long-duration, rate-sensitive
US Money Market Funds 4.5–5.0% Near risk-free, highly liquid
China Yu'e Bao (余额宝) 1.5–2.0% Alipay money market fund
EU Bank Savings (avg) 2.5–3.5% Varies by country

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.
