Api stored libraries upload create

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

Annotations already declare readOnlyHint=false, openWorldHint=true, idempotentHint=false and destructiveHint=false, so the safety profile is partly covered. But the description adds nothing about upload semantics: what payload format is accepted, whether it is multipart, whether an existing library is replaced, or what errors occur. For a write operation whose only parameter is an untyped object, that silence is costly.

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 is pure under-specification rather than efficient communication: a single snake_case echo of the tool name. Nothing is front-loaded because nothing informative is present.

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?

A mutating upload endpoint with no output schema, an undocumented free-form body, and an extremely dense sibling namespace requires far more context than the name echo provides. An agent cannot safely or correctly call this tool from the definition alone.

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 `body` parameter is an unconstrained object with 0% schema description coverage, and the description offers no hint of what the body should contain. The agent has no source of meaning for the only input at all.

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 just the operation ID "api_stored_libraries_upload_create" restated in prose form. It implies an upload into stored libraries but never states in plain language what the tool does, and it does not distinguish itself from close siblings like stored_libraries_import_create or stored_libraries_create.

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?

No when-to-use, when-not-to-use, or alternative is mentioned. With siblings such as import_create, create, and content_retrieve in the same resource family, the agent is left to infer the upload path entirely from the raw identifier.

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