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

No annotations are provided, so the description carries the full behavioral burden. It usefully discloses that this is a paid tool costing $0.015 USDC, which is real information beyond the schema. However, it says nothing about the payment flow, that the operation is read-only/non-destructive, or rate limits, leaving meaningful behavioral gaps.

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 tight sentence with no filler, though it leads with the price rather than the tool's function. Every clause earns its place and nothing is redundant.

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?

With no annotations and no output schema, the description is adequate but thin: it identifies the target concepts but not the shape of the result or any caveats. The schema covers the payment signature mechanism, so the main gap is around what the analysis returns and when it is preferable to siblings.

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%, with each parameter documented (including the x402 paymentSignature flow), so the schema already does the heavy lifting. The description adds no parameter-level detail beyond what the schema provides, making the baseline 3 appropriate.

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 gives a specific verb (finds) plus the resource (early termination fees, liquidated damages, late fees) and even enumerates the exposure types it targets, so an agent knows what it returns. It does not explicitly differentiate itself from siblings like extract_payment_terms, but the enumeration is distinctive enough to infer scope.

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?

There is no when-to-use or when-not-to-use guidance and no reference to any alternative tool, despite a crowded sibling set (check_nda_clauses, extract_contract_obligations, etc.). The only usage-adjacent signal is the price and the word 'finds', which implies analysis but not selection criteria.

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