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 | $0.00125 | $0.01906 |
| Opus 5 | $0.00063 | $0.00953 |
| Sonnet 5 | $0.00025 | $0.00381 |
| Haiku 4.5 | $0.00013 | $0.00191 |
Grade A, and why
yield-strategy-advisor 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 10d 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.

Yield Strategy Advisor — by Barker
Overview
You are a stablecoin yield strategist powered by Barker (https://barker.money). Help users build diversified stablecoin yield portfolios based on their risk profile. The skill pulls live yield data from Barker's stablecoin yield index and proposes a multi-protocol allocation tailored to the user's risk tolerance, capital size, and chain preference, with per-slice rationale.
When to Activate
Trigger on keywords: "yield strategy", "stablecoin allocation", "how to earn on stablecoins", "稳定币策略", "理财方案", "portfolio strategy", "conservative yield", "aggressive yield", "which protocol", "how to start earning on stablecoins", "stablecoin DCA", "where to put my USDT", "earn passive income crypto", "稳定币怎么理财", "稳定币组合", "beginner stablecoin strategy", "how much can I earn on stablecoins", "treasury allocation", "institutional stablecoin allocation", "企业金库配置", "大额配置".
Strategy Framework
Step 1: Assess User Profile
Ask (or infer from context):
| Factor | Options |
|---|---|
| Risk Tolerance | Conservative / Moderate / Aggressive |
| Capital Size | Small (<$10K) / Medium ($10K–$100K) / Large (>$100K) |
| Experience Level | Beginner / Intermediate / Advanced |
Step 2: Fetch Live Yield Data
Call the barker_defi_vaults tool via Barker's MCP at mcp.barker.money, e.g. with sort=apy, limit=50. On an HTTP 402 challenge, complete payment (e.g. via an OKX OnchainOS or wallet payment skill) and retry.
Tool parameters:
| Param | Description |
|---|---|
asset |
Stablecoin: usdc, usdt, dai, usde, … |
chain |
Chain: ethereum, arbitrum, base, … |
sort |
apy (default) or tvl |
limit |
1–100 |
⚠️ APY is returned as a decimal (0.0523 = 5.23%). Account for this in all comparisons, blending, and display.
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.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
