get_collection_value

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It conveys that the operation is a read-only 'get' and scoped to the authenticated user, but it does not describe response format, authentication requirements, potential errors, or what the value estimate is based on.

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 with no filler, making it efficient and easy to parse. It is slightly under-sized given the undocumented username parameter, but as a structural matter it is concise without being tautological.

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 tool with no annotations, no output schema, and an undocumented parameter, a one-line description is incomplete. The agent would not know how to handle the optional username parameter, what the response contains, or whether additional authentication context is needed.

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 has one parameter, username, with 0% description coverage, and the tool description never mentions it. The description's 'authenticated user's' framing makes the optional username parameter confusing, and no explanation is provided for when or why it should be used.

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 action ('Get') and the resource ('authenticated user's collection value estimate'), which is distinct from sibling tools like get_collection or get_price_suggestions. However, it does not explicitly contrast those alternatives, and the optional username parameter introduces slight ambiguity about whose value is returned.

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 about when to use this tool instead of related collection or pricing tools, nor does it explain prerequisites such as authentication or whether username should be supplied for other users. The only usage cue is inferred from the tool's purpose, which is not enough for reliable tool selection.

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