Coinglass: getCoinglassGrayscaleHoldings

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

The annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, and openWorldHint=true, indicating a safe read-only operation. The description adds no additional behavioral traits beyond what the annotations provide—e.g., no mention of data freshness limits, pagination behavior, or any side effects.

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 a single concise sentence that wastes no words. It is front-loaded and to the point, earning 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?

The tool has no output schema, so the description would ideally describe what the output contains (e.g., list of holdings with fields like ticker, amount, etc.). It does not, but the annotations are rich and the parameters are simple. The description is adequate but incomplete for an agent to fully understand the tool's response.

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 has 2 parameters (page, limit) with descriptions covering 100% of parameters. The description does not add any extra meaning beyond the schema, but the schema is sufficient. Baseline 3 is appropriate given full schema coverage.

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 clearly states it provides a list of holdings managed by Grayscale Investments. It uses a specific verb ('provides a list') and specific resource ('holdings managed by Grayscale Investments'), distinguishing it from sibling tools like getCoinglassBitcoinEtfList or getCoinglassExchangeAssets.

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?

The description offers no guidance on when to use this tool versus alternatives. There is no mention of context, prerequisites, or scenarios where another tool would be more appropriate. The sibling list includes many similar Coinglass tools, but no differentiation is provided.

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