get_user_collection_folder

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

Without annotations, the description fails to disclose behavioral traits beyond the obvious read operation. It does not state whether the tool requires authentication, what happens if the folder does not exist, or rate limits. The phrase 'Retrieve metadata' implies no side effects, but no explicit confirmation of safety or error handling is provided.

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 gets straight to the point. While it could benefit from additional details, it is well-structured and front-loaded, avoiding unnecessary words. It achieves the goal of brevity without sacrificing core meaning.

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 the absence of annotations, output schema, and parameter descriptions, the description lacks completeness. It does not specify what metadata is returned, error scenarios, or how to interpret the response. For a read operation with two required parameters, this leaves significant gaps for an AI agent to safely invoke the tool.

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 coverage is 0%, meaning the input schema lacks descriptions for 'username' and 'folder_id'. The description does not compensate by explaining these parameters, such as what the folder_id represents or how to obtain it. It merely implies their existence through the phrase 'folder in a user's collection', which is insufficient for correct parameter usage.

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 'Retrieve metadata about a folder in a user's collection' uses a specific verb 'Retrieve' and clearly identifies the resource (folder metadata) and context (user's collection). It effectively distinguishes from sibling tools like 'get_user_collection_folders' (list all folders) and create/edit/delete operations, leaving no ambiguity about its function.

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 prerequisites, when not to use it, or how it compares to related tools such as 'get_user_collection_folders' for listing all folders. An agent must infer usage from the tool name alone.

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