Api loaded libraries update

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

Annotations already declare readOnlyHint=false, idempotentHint=true, destructiveHint=false and openWorldHint=true, so the safety profile is covered without the description. The description itself contributes nothing beyond those hints — no mention of what gets overwritten, required permissions, or the semantics of a full update versus a partial one.

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 text is a single token with no waste, but this is under-specification rather than conciseness. There is no front-loaded verb-object statement of what is being updated or how.

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 write operation with a free-form 'body' payload, zero schema description coverage, and no output schema, the definition is completely inadequate — an agent cannot construct a valid body or predict the effect of the call.

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 0% for two parameters (id and an untyped 'body' object). The description says nothing about either, leaving the shape of the update payload entirely undocumented in both schema and prose.

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 'api_loaded_libraries_update' is a restatement of the tool name/title and adds no explanatory content. An agent can infer a mutation of loaded libraries from the name alone, but nothing in the description confirms the resource scope or distinguishes this from siblings like loaded_libraries_partial_update or loaded_libraries_batch_action_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 guidance, no mention of alternatives (partial_update, batch_action_create, available_updates_retrieve), and no prerequisites. The agent is left to guess from the name whether this is a full replace vs. a partial update.

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