List Manifold market comments

manifold_comments
Read-onlyIdempotent

Get comments on a prediction market contract to understand crowd reasoning and sentiment behind forecasts.

Instructions

Comments on a single market — useful for crowd reasoning and sentiment behind a forecast. Example: { contractId: 'ZtAEnyhO29' }

Behavior2/5

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint. The description adds only an example and does not disclose additional behavioral traits such as return format, ordering, or potential limits.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Extremely concise: two sentences plus an inline example. No wasted words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has a single parameter and rich annotations, the description is adequate but does not describe the output format (e.g., array of objects with fields like text, author).

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The single parameter contractId is fully described in the schema. The description reinforces its meaning with an example, adding value beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states the tool lists comments on a single market, with a concrete example using a contractId. Distinguishes from sibling tools like manifold_bets and manifold_list_markets.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Indicates the tool is useful for crowd reasoning and sentiment behind a forecast, implying when to use it. Does not explicitly mention alternatives or when not to use, but context of single market is clear.

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