create_younify_connect

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

Annotations already establish readOnlyHint=false, openWorldHint=true, idempotentHint=true, and destructiveHint=false—so this is clearly a non-destructive, open-world, idempotent creation operation. The description adds only that 'Create a streaming connection' and the endpoint, which is consistent with annotations but provides little extra behavioral context. It doesn't describe side effects or requirements beyond pointing to the GET/schema endpoint, which is mildly helpful but not rich. No contradiction with annotations.

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?

Three short sentences: the purpose, the HTTP method/path, and a parameter note with discovery guidance. Every sentence earns its place, the key action is front-loaded, and there is no redundant content. The description is tight and scannable.

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?

The tool is simple (one free-form body parameter) and annotations plus output schema reduce the need for detailed return-value explanation. However, the description does not explain what a streaming connection is, when creating one is appropriate, or any prerequisites such as authentication. It gives enough to start using the tool (read GET/schema) but leaves contextual gaps around purpose and usage that would help an agent decide to invoke it.

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 body parameter is a free-form object (additionalProperties: true) with zero schema description coverage. The description compensates by labeling 'body: Request payload' and explicitly instructing the agent to read the matching GET or /schema endpoint to discover expected fields. This is a practical, actionable semantic pointer for a schema that lacks any field definitions, exceeding what the raw schema provides.

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 opens with a clear verb and resource: 'Create a streaming connection.' The explicit endpoint 'POST /younify/connect' further anchors what operation is performed. While the name already conveys most of this, the description confirms the action and resource unambiguously, though it doesn't explicitly contrast with sibling tools.

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 guidance is given about when to use this tool versus alternatives. The only usage-related note, 'Read the matching GET or the /schema endpoint first to see the fields this resource expects,' is about how to construct the request, not about when to select this tool. There is no mention of exclusions or conditions that differentiate it from the many sibling create_* tools.

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