RegimeShift — regime-aware risk & rate benchmarks for agents on Base

Adds the regimeshift skill: quantitative risk/rate inputs an on-chain agent needs before sizing a position, pricing an inter-agent loan, or gating leverage to the current market regime.

Install

> install the regimeshift skill from https://github.com/BankrBot/skills/tree/main/regimeshift

Four read-only GET tools — $0.001 USDC per call via x402 on Base (eip155:8453), or the same tools over MCP (https://mcp.regimeshift.xyz/mcp):

Tool	Returns
eth_vrp / btc_vrp	Volatility risk premium = Deribit DVOL − Parkinson RV(72h) + LOW/MID/HIGH regime. Positive ⇒ sell-vol.
agent_sofr	Decentralized USD short rate (horizon 1h/1d/1w), decomposed into base + variance + regime.
max_ltv	Regime-capped max-safe LTV for a collateralized loan + which constraint binds (math vs regime cap).

Notes for review

• Payment is standard x402 v2: HTTP 402 with the challenge in the payment-required header; exact scheme, USDC 0x8335…2913, payTo 0x82B17D…cd7B. Any x402 client (TS x402-fetch / @coinbase/x402, Python x402) settles automatically — same pattern as the alchemy / zerion skills. A funded Bankr agent wallet is a valid payer.
• Every response returns its raw inputs + an open methodology URL, so outputs are auditable rather than black-box.
• All endpoints and example responses in SKILL.md were verified live against the production regimeshift.xyz 402 envelopes.
• Single SKILL.md, MIT-licensed. No scripts, no secrets.

Rebased onto latest main — this is now a single clean commit, conflict-free and mergeable.

What it adds: a regimeshift skill for regime-aware risk & rate benchmarks on Base — ETH/BTC variance risk premium, the Agent-SOFR short rate, and volatility-regime max-LTV. Callable pay-per-call via x402 ($0.001 USDC, no account or API key) or over MCP; every response carries its raw inputs plus an open, versioned methodology URL for audit.

Happy to adjust anything you'd like. Thanks for maintaining the marketplace.
