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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered, but the description adds nothing beyond that — no mention of pagination behavior despite a cursor parameter, result shape, or freshness/rate characteristics of Polymarket data.

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?

It is a single short fragment, which reads as under-specification rather than efficiency. For a six-parameter, paginated listing tool in a dense sibling namespace, one noun phrase does not earn its place.

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?

An output schema exists so return values need not be explained, but the description omits what distinguishes this listing endpoint from the many other polymarket_* tools and gives no behavioral context for a paginated feed.

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 clear per-parameter docs for tag, sort, limit, cursor, status, and recurrence. The description adds no additional meaning, so the baseline 3 applies.

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 predictions page events.' essentially restates the tool name without a clear verb or resource distinction. It is ambiguous whether it lists events, predictions, or a paginated feed, and it does not differentiate from siblings like polymarket_events or polymarket_homepage_feed.

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 guidance on when to use this tool versus polymarket_events, polymarket_markets, or polymarket_search. The agent must infer usage entirely from the name and schema.

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