kalshi_mve_collection

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

Annotations already establish read-only, idempotent, and open-world behavior. The description adds useful context by stating 'Auth: none needed' and specifying the return structure, which is valuable given the absence of an output schema. No contradictions with annotations.

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 description is extremely concise, with one sentence for purpose, one for return payload, and one for authentication. Every element earns its place with no redundancy or padding.

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 simple read-only single-item lookup, the description provides adequate context: it states the input (ticker), the return shape, and the auth requirement. It does not discuss error scenarios or edge cases, but these are less critical given the low complexity and the presence of schema and annotations.

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?

The input schema provides 100% description coverage for the single collectionTicker parameter, including the fact that it is required and part of the URL path. The tool description does not add any additional parameter-level semantics beyond what the schema already states.

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 "One multivariate event collection by ticker" clearly identifies the resource and retrieval action, and its singular form distinguishes it from the plural sibling tool kalshi_mve_collections. However, it lacks an explicit verb like 'get' or 'fetch,' which makes the intended operation slightly less direct.

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 explicit guidance on when to use this tool versus alternatives. The singular/plural distinction with kalshi_mve_collections hints at a specific use case, but no when/when-not criteria or alternative recommendations are provided.

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