fetch_collection_schema

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

The description discloses that the schema is 'inferred' and based on 'a sample document', which hints at approximate or non-exhaustive results. However, since there are no annotations, the description carries the burden for safety and behavioral context, and it does not explicitly state that the operation is read-only or without side effects. The sample-based nature adds some transparency but lacks depth.

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 states exactly what the tool does with no wasted words. It is highly concise and easy to parse.

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 tool with one parameter, the description is adequate but not rich. It lacks context about when to prefer this over fetch_collection_data or other siblings, and it does not clarify whether the operation is safe or read-only. However, given the minimal input schema and no output schema, the description is not severely incomplete, though it leaves room for improvement.

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 schema description coverage is 0%, and the description does not mention the parameter at all. While the parameter name 'collection_name' is relatively self-explanatory given the tool name, the description provides no additional meaning or context, such as the format or expected values. With low coverage, the description should compensate but fails to do so.

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 the tool's function: it returns an inferred schema from a sample document. This distinguishes it from siblings like fetch_collection_data (which fetches data) and all_collections (which lists collections). The verb 'Returns' combined with the resource 'schema' makes the purpose unambiguous.

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 provides no guidance on when to use this tool versus alternatives. It does not mention that it should be used specifically for schema inspection, nor does it note any exclusions or alternative tools. Usage is only implied by the tool name and description.

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