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

With no annotations, the description carries the full burden of behavioral disclosure. It adds useful context about parsing CSV/XLSX and the scope gate prerequisite, but it does not disclose potential side effects, return structure, error behavior, or access requirements, so it remains thin.

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, front-loaded sentence that immediately states the verb and resource. There is no filler or redundant phrasing, making it highly concise.

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?

Given 5 parameters, no annotations, and no output schema, this description is too minimal. It does not clarify how parameters interact, what 'shared scope gate' entails, what the tool returns, or failure behavior, leaving major gaps for a tool of this complexity.

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 0% and the description provides no explanation of the five parameters (url, file_url, max_rows, question, sheet_name). The agent is left to guess parameter meaning from names alone, which is inadequate for a multi-parameter tool.

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 a specific action ('fetch and parse') and resource ('linked CSV or XLSX file'), and the formats help distinguish it from sibling publication/query tools. However, it does not explicitly differentiate itself by naming alternatives or exclusions.

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 phrase 'after passing the shared scope gate' implies a prerequisite and some contextual timing, likely related to check_query_scope, but it is vague and does not explicitly state when to use this tool versus alternatives or when not to use it.

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