get_chain_defi_status

Retrieve total TVL, native token, and top 5 protocols by TVL for any major blockchain network.

Instructions

High-level DeFi stats for any major chain (default: Ethereum). Returns total TVL, native token, top 5 protocols by TVL. Supports Ethereum, Cardano, Solana, Arbitrum, Optimism, Base, Polygon, etc.

TDQS

A4.3/5.0
Behavior4/5

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

No annotations provided, so description bears full burden. It describes a read-only operation returning TVL, native token, and top 5 protocols, with no destructive side effects. Could be more transparent about limitations (e.g., 'only top 5 protocols, data may be delayed') but current disclosure is adequate for a simple query.

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

Conciseness5/5

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

Two sentences, no filler. Front-loaded with purpose and default, then specific returns and supported chains. Every word earns its place.

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

Completeness5/5

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

Given the tool's simplicity (one optional parameter, no output schema), the description is sufficiently complete: it explains what it does, what it returns, and which chains it supports. An agent can confidently select and invoke the tool based on this description.

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

Parameters4/5

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

Schema coverage is 100% with one parameter 'chain' having a description of casing and examples. Description adds explicit list of supported chains (Ethereum, Cardano, Solana, etc.) beyond schema examples, giving agents concrete options to use. This adds value over the schema alone.

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?

Description clearly states the tool provides high-level DeFi stats for major chains, specifying return values: total TVL, native token, top 5 protocols. Distinguishes from sibling tools like get_protocol_tvl (protocol-level) or list_top_protocols (cross-chain) by focusing on chain-level aggregated data.

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

Usage Guidelines3/5

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

No explicit guidance on when to use versus alternatives. Implies usage for major chains by listing supported ones, but does not state when not to use or suggest other tools. A statement like 'Use for chain overview; for specific protocol details, see get_protocol_tvl' would improve the score.

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