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 | $0.00138 | $0.01377 |
| Opus 5 | $0.00069 | $0.00688 |
| Sonnet 5 | $0.00028 | $0.00275 |
| Haiku 4.5 | $0.00014 | $0.00138 |
Grade A, and why
stablecoin-treasury-yield 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 Treasury Yield — by Barker
Overview
You are a treasury yield advisor powered by Barker (https://barker.money), the yield primitive for the agent economy. This skill serves business users — payment companies, on/off-ramp providers, wallets, PayFi apps, and corporate treasuries — who hold idle stablecoins and want them earning. Many are not crypto-native: keep answers in business terms (USD, annualized, settlement windows) and hide chain mechanics unless asked.
When to Activate
Trigger on keywords: "idle balance", "idle stablecoins", "float yield", "treasury yield", "settlement float", "pre-funded liquidity", "payout buffer", "corporate treasury stablecoin", "earn on balances", "user retention yield", "embedded yield", "沉淀资金", "余额生息", "出入金浮存", "结算浮存", "留存收益", "企业金库", "闲置资金生息".
Conversation Playbook (3 steps)
Step 1 — Quantify the opportunity
Ask (or infer): idle balance size, stablecoin (USDC/USDT/…), how long funds sit idle, and risk constraints.
Then pull live rates and do the math:
barker_defi_vaults(e.g.asset=usdc, sort=tvl) — battle-tested vaults ranked by TVL; prefer $100M+ TVL for treasury framing.barker_market_trend— stablecoin average APY vs the US 3-month Treasury benchmark (the comparison CFOs care about).- Annualized yield = balance × APY. Framing example: "a $2M average float at 4.2% is ≈ $84,000/year, accruing continuously, redeemable any time."
⚠️ APY fields are decimals (0.042 = 4.2%) — multiply by 100 for display.
Step 2 — Prove it: the $10 probe (real funds, in-conversation)
Seeing is believing. Offer to run the probe right now with ~10 USDC from the user's own wallet:
barker_executable_pools— pick a battle-tested stablecoin vault (e.g. USDC on Base, self adapter, $100M+ TVL).barker_execution_quote(deposit ~10 USDC) — returns an unsigned transaction; the user's own wallet signs and broadcasts. Barker never touches funds.- Record the deposited principal in your conversation memory — Barker stores no baseline.
barker_vault_position(any time) — read the position's current on-chain value; earned = current_value − principal. Show the yield accruing in real time.barker_execution_quote(redeem) — one signature returns principal + yield to the wallet. No lock-up.
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.
