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

With no annotations, the description carries the behavioral transparency burden. It discloses a prerequisite (Manage Team scope) and implies a read-only operation via the GET endpoint, which is useful. However, it does not describe pagination behavior, response format, or any side-effect-free guarantee explicitly, so only partial transparency 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 two short sentences with no filler. It front-loads the action, includes the endpoint, and tucks the scope requirement into a separate sentence. Every word earns 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?

For a simple read-only list tool with 100% parameter coverage, the combination of description and schema is nearly sufficient: the agent knows what to call, what arguments to pass, and what permission is needed. However, the lack of any usage guidance, response format hints, or behavior notes means an agent may not know what results to expect or when to choose this over other list tools.

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 100%, so the input schema fully documents all four parameters (page, type, limit, user_id) with their meanings and defaults. The description itself adds no parameter-specific detail, so the baseline of 3 is appropriate.

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 uses a specific verb-resource pair ('Get member-uploaded media') and includes the endpoint, making the core purpose clear. It does not explicitly differentiate from sibling list tools, but none of the listed siblings target media, so ambiguity is low. The phrase 'member-uploaded' adds useful scope.

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 gives no guidance on when to prefer this tool over alternatives, nor does it mention any exclusions or related tools. It states a scope requirement but not the context in which an agent should pick this tool. This is a significant gap for a list endpoint with many sibling tools.

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