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

Annotations are present but only indicate the tool is not read-only, not idempotent, and not destructive. The description adds minimal behavioral context: it creates a new connection but does not disclose the impact on existing connections, authentication requirements, or handling of secrets. For a mutation tool, this is insufficient.

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 only two sentences, but they are nearly identical: 'Create Workspace Auth Connection' and 'Create a new OAuth2 auth connection for the workspace' repeat the same information. The redundancy makes it less concise than a single well-crafted sentence would be.

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?

Given the complexity of the input schema (multiple OAuth2 variants), the absence of annotations, and no output schema, the two-sentence description is completely inadequate. It does not explain the purpose of the 'body' object, the meaning of fields like 'auth_type', or how the tool behaves across the different variants.

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?

With 0% schema description coverage, the description must explain the parameters, but it does not mention 'body' or 'account' at all. The schema shows seven distinct OAuth2 variant shapes, but the description offers no guidance on which variant to select or what each field means, leaving the agent completely in the dark.

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 ('Create') and resource ('Workspace Auth Connection'), adding specificity with 'OAuth2'. However, it contains a redundant first sentence that merely rephrases the tool name, and it does not distinguish this from sibling tools like update or list auth connections.

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 offers no guidance on when to use this tool versus alternatives such as elevenlabs_update_auth_connection or elevenlabs_delete_auth_connection. It also does not mention any prerequisites, when a new connection is needed, or how to choose among the various OAuth2 flows.

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