Api loaded libraries tree retrieve

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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds nothing on top of that: it does not say what the tree contains, whether it spans all loaded libraries or only the one identified, or what depth of nesting is returned. No contradiction, but zero added value.

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?

It is short, but the brevity comes from having no content rather than from tight editing. The single token string is a redundant restatement of the tool name, so nothing is front-loaded because nothing is said.

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 retrieve tool with no output schema and an undescribed identifier parameter, the description must carry the entire burden of explaining input meaning and return shape. It carries none of it, so an agent cannot call this correctly without guessing at what 'id' refers to and what a 'tree' response looks like.

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 single required parameter 'id' has 0% schema description coverage, so the schema supplies only 'type: string'. The description does not clarify whether this is a loaded-library id, a stored-library id, a framework id, or a node id, leaving the one thing an agent must know before calling it undocumented.

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 is the tool's identifier repeated verbatim ('api_loaded_libraries_tree_retrieve'), so it restates the name rather than stating what the tool does. An agent learns only that something about 'loaded libraries' is retrieved as a 'tree', with no verb-plus-resource phrasing and no differentiation from loaded_libraries_retrieve, loaded_libraries_content_retrieve, or stored_libraries_tree_retrieve.

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?

There is no when-to-use, when-not-to-use, or alternative guidance of any kind. In a sibling set this large, with near-duplicate names like loaded_libraries_content_retrieve and stored_libraries_tree_retrieve, the absence of routing guidance is a serious gap rather than a minor omission.

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