Defi Yield Scanner

Scan DeFi protocols for the best yield opportunities. Covers Aave, Compound, Curve, Yearn, Uniswap v3, and emerging L2 protocols. Compares APY vs risk, track...

Security Scan

The skill's declared purpose (scanning DeFi APYs across public protocols) matches its instructions and resource needs; it uses public APIs and requests no credentials or installs.

Purpose & Capability

Name/description (DeFi yield scanner) align with the instructions: it pulls APY/TVL/metadata from public DeFi APIs (DeFiLlama, Curve, Yearn, The Graph/Aave). No unrelated binaries, creds, or config paths are requested.

Instruction Scope

SKILL.md is high-level: it instructs the agent to fetch live APY/TVL and apply risk filters and return entry instructions. It does not ask for private keys or local files, but is vague about exact queries, risk-data sources, or whether the agent should ever initiate on-chain transactions or request wallet signing. That vagueness grants the agent discretionary actions unless constrained by the platform.

Install Mechanism

Instruction-only skill with no install spec and no code files — nothing is written to disk and no external packages are pulled. This is the lowest install risk.

Credentials

The skill requires no environment variables, credentials, or config paths. This is proportionate for a read-only data-aggregation scanner using public APIs.

Persistence & Privilege

always is false and the skill does not request persistent privileges or modifications to other skills or system-wide settings. It can be invoked by the agent normally (default autonomous invocation), which is expected for a data-fetching skill.

Assessment

This skill appears coherent with its stated purpose and uses public DeFi APIs only, but review these points before installing: 1) Confirm you are comfortable with the agent making outbound network requests to the listed endpoints (api.llama.fi, curve.fi, yearn.fi, The Graph/Aave); 2) The SKILL.md is intentionally high-level — clarify whether the agent is permitted to execute transactions or request wallet signing (it currently does not ask for keys, and you should never supply private keys); 3) Expect no built-in authentication — some APIs may require rate-limited keys or return incomplete data under heavy use; 4) Treat recommendations as informational, not investment advice; test on small amounts or in a sandbox before acting on execution instructions; 5) If you need stronger controls, require the skill to explicitly list queries it will run and to never initiate on-chain transactions without explicit user confirmation.

Autonomous scanner for DeFi yield opportunities across 10+ protocols.

What It Scans

• Aave v3 (Polygon, Arbitrum, Base): supply APY, borrow APY, utilization rate
• Compound v3: USDC/USDT supply rates, COMP reward APR
• Curve Finance: stable pools, CRV emissions, gauge weights
• Uniswap v3: fee tier APY for concentrated liquidity positions
• Yearn Finance: vault APY including harvesting strategy returns

Yield Ranking

Each opportunity is scored on:

1. APY (raw + adjusted for token emissions)
2. Risk (smart contract age, audit status, TVL)
3. Sustainability (emission-adjusted vs organic APY)
4. Gas efficiency (on Polygon/L2 vs mainnet)

How to Use

Ask: "Find the best stable yield on Polygon right now" or "Compare USDC yields across Aave, Compound, Curve"

The agent fetches live APY data, applies risk filters, and returns ranked opportunities with entry instructions.

Data Sources

• DeFiLlama API (api.llama.fi) — TVL, APY, protocol metadata
• Aave subgraph (The Graph)
• Curve registry (curve.fi/api)
• Yearn vaults API (yearn.fi/api)
