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

With no annotations, the description carries the full burden and does substantial work: it discloses the evidence sources consulted, that loss is quantified with Chainlink prices at the loss block, that clause mapping is verbatim-verified, and that similar past claims are cited. It falls short on the response shape because the sentence truncates mid-token at 'FILE / FILE_WI', leaving the verdict enumeration and any side effects or cost unstated.

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?

The purpose is front-loaded in the first clause, which is correct. But the rest is a single dense run-on chain of capabilities, and the final parenthesis is cut off mid-word, which is a genuine structural defect rather than mere brevity.

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?

This is a complex tool — eight parameters, nested objects, no annotations and no output schema — so the description must do heavy lifting. It covers methodology and evidence sources well but leaves the return structure incomplete due to truncation and never addresses whether the analysis is read-only, how long it takes, or what happens when on-chain loss cannot be established.

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 coverage is 75%, so the schema already explains most fields (cover asset/amount, wording url vs text precedence, deductible basis) at a high level. The description only implicitly references wording, incident postmortems and transactions, and says nothing about deductible, claimedLoss being always reported as unverified, or claimDate — so it adds modest meaning over the schema rather than compensating for the uncovered quarter.

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?

States a specific verb and resource: predicts whether a DeFi cover claim will be approved and for how much, and enumerates the evidence it reads (wording, postmortems, claimant transactions). That scope is unmistakably distinct from siblings like arbitrage-lawyer or dispute-ev without needing to name them.

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 implied by the purpose — an agent would invoke it when adjudicating a cover claim — but there is no explicit when-to-use, when-not-to-use, or routing to an alternative such as dispute-ev. Nothing tells the agent what prerequisites (wording or incident data) are mandatory before calling.

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