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

No annotations are provided, so the description carries the full burden of behavioral disclosure, and it reveals nothing: no indication of read-only vs. mutating behavior, no return format, no mention of live-data dependencies, rate limits, or prerequisites. The agent is left with zero behavioral expectations beyond the bare subject matter.

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?

At six words, the description is short, but this is under-specification rather than conciseness. The single sentence merely restates the name and earns no informational value, so it fails the standard that every sentence should add meaning.

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 tool with six optional parameters, no annotations, no output schema, and a cluster of near-identical sibling tools, this description is completely inadequate. An agent cannot determine what action to take, which parameter to populate, what response to expect, or how this differs from sibling Polymarket tools.

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 nominally 100%, but every parameter description is the vacuous boilerplate 'X to process,' which adds no meaning beyond the parameter name itself. With six optional string parameters (q, id, slug, search, marketId, question), the agent has no way to know which identifier to supply or what format each expects, and the main description offers no compensation.

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 'Polymarket Odds: Polymarket market odds.' is a tautology that restates the tool's name. It identifies the domain (Polymarket odds) but contains no verb or action, so an agent cannot tell whether the tool fetches, calculates, compares, or lists odds. It also does nothing to distinguish this from domain siblings like x402-polymarket, x402-poly-markets, x402-polymarket-scan, or x402-poly-price.

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?

No guidance is given on when to use this tool versus the many closely related siblings in the same domain. There are no context hints, no exclusions, and no alternative tool names mentioned, leaving the agent to guess which of the similar Polymarket tools to select.

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