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

No annotations are supplied, so the description carries the full behavioral burden. It never states that this is a read-only data query, whether any authentication or API key is needed, how fresh the DeFiLlama data is, whether results are paginated or truncated by maxResults, or what the response looks like for each of the three modes — 'live ... intelligence' is the only hint, and it is vague.

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

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

A single front-loaded sentence that names the capability set and the data source with no filler or repetition. Every clause earns its place by identifying a distinct monitoring domain.

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

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

For a 4-parameter, all-optional tool with no output schema and no annotations, the description covers what domains exist but omits what happens with defaults, how each mode's output differs, and the read-only/safety profile. It is adequate to attempt a first call but leaves meaningful gaps.

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

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

Schema description coverage is 100%, so the schema already documents mode, chains, minTvlUsd, and maxResults, making 3 the baseline. The description adds only indirect meaning by naming the three data domains that correspond to the mode values; it adds no syntax, default behavior, or filtering semantics beyond the schema.

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

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

The description pairs the verb 'Monitor' with three concrete resources — yield farming APY pools, multi-chain protocol TVL, and stablecoin peg health — and names the data source (DeFiLlama), which is far more specific than the sibling crypto tools like crypto_orderbook_arbitrage_scanner or dex_token_scanner_security_auditor. It stops short of explicitly differentiating itself from those crypto siblings, so a 4 rather than a 5.

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

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

Usage is only implied: the three domains map to the three 'mode' values, so an agent can infer when this tool fits, but there is no explicit when-to-use or when-not-to-use guidance and no named alternative such as the DEX security or orderbook scanners. 'Monitor' also suggests recurring/polling use without stating it.

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