[AUTO-INVOKE] MUST be invoked BEFORE deploying DeFi contracts (DEX, lending, staking, LP, token). Covers anti-whale, anti-MEV, flash loan protection, launch checklists, and emergency response. Trigger: any deployment or security review of DeFi-related contracts.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# DeFi Security Principles ## Language Rule - **Always respond in the same language the user is using.** If the user asks in Chinese, respond in Chinese. If in English, respond in English. > **Scope**: Only applicable to DeFi projects (DEX, lending, staking, LP, yield). Non-DeFi projects can ignore this skill. ## Protection Decision Rules | Threat | Required Protection | |--------|-------------------| | Whale manipulation | Daily transaction caps + per-tx amount limits + cooldown window | | MEV / sandwich attack | EOA-only checks (`msg.sender == tx.origin`), or use commit-reveal pattern | | Arbitrage | Referral binding + liquidity distribution + fixed yield model + lock period | | Reentrancy | `ReentrancyGuard` on all external-call functions (see solidity-security skill) | | Flash loan attack | Check `block.number` change between operations, or use TWAP pricing | | Price manipulation | Chainlink oracle or TWAP — never rely on spot AMM reserves for pricing | | Approval exploit | Use `safeIncreaseAllowance` / `safeDecreaseAllowance`, never raw `approve` for user flows | …

How to install
mdr add 0xlayerghost/solidity-agent-kit/defi-security@sha256:0c110bf7ba0e9f28The line at the top of this page pins the label git:20260415.0ecbefe, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
