defi-market-pulse

Identify high-APY yield pools alongside crypto and equity market movers, with cross-signals highlighting boosted or at-risk opportunities for capital allocation and portfolio rebalancing.

Instructions

Combined DeFi yield intelligence and market momentum in one call — 33% cheaper than separate yield-farming-active + market-movers calls ($0.009). Returns top yield pools from DeFiLlama, crypto and equity market movers, and a cross-signal layer that flags 'boosted' pools (high APY + rising token) vs 'at_risk' pools (high APY + falling token). Use for capital allocation decisions, pre-trade DeFi context, and portfolio rebalancing signals.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
chainNoFilter yield pools by blockchain (e.g. 'Ethereum', 'Base', 'Arbitrum'). Case-insensitive. Omit for all chains.
protocolNoFilter yield pools by protocol name (e.g. 'aave-v3', 'uniswap-v3'). Substring match.
min_tvl_usdNoMinimum TVL in USD for yield pools. Default $1M.
min_apyNoMinimum 30-day mean APY percentage. Default 5%.
stablecoin_onlyNoReturn only stablecoin yield pools (no impermanent loss). Default false.
yield_limitNoNumber of yield pools to return (1–30, default 15).
market_limitNoNumber of market movers per category (1–20, default 10).
include_equityNoInclude equity market movers (US stocks). Default false — crypto only for speed.
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Despite no annotations, the description adequately discloses that it is a read operation returning combined data with no destructive effects. Mentions cost savings and the cross-signal layer, but lacks details on real-time vs historical or rate limits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Five sentences, front-loading value proposition and cost savings. Could be more structured but is appropriately concise given the tool's complexity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema, but description outlines the three layers returned (yield pools, market movers, signals). Adequate for understanding the output structure, though more detail on format would be helpful.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% so baseline is 3. Description adds context about the tool's combined nature and output layers but does not enhance individual parameter meaning beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states that the tool combines DeFi yield intelligence and market momentum, distinguishes from siblings by mentioning cheaper alternative to separate calls, and specifies verb (returns) and resources (yield pools, market movers, cross-signal layer).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly states use cases: capital allocation decisions, pre-trade context, portfolio rebalancing. Implicitly differentiates from alternatives but does not explicitly state when not to use.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
