create_connections

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It only reveals that the tool uses the default connector style, but does not mention return values, error behavior (e.g., invalid node IDs), side effects (e.g., overwriting existing connections), or permissions. This is insufficient for a mutation tool.

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 a single, front-loaded sentence that efficiently conveys the core purpose. It is concise, but it may be slightly underspecified for a mutation tool, leaving gaps that additional context would fill.

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 tool has only one parameter, no output schema, and no annotations, the description is minimally adequate. It does not explain behavior on failure, whether multiple connections can be created in a single call (though the schema implies this), or what happens if the default style is not set. More context would be beneficial.

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 input schema provides descriptions for all parameters (startNodeId, endNodeId, text) with 100% coverage. The description adds no additional parameter semantics beyond what the schema already offers, so the baseline score of 3 applies.

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 specific action ('Create connections between nodes') and the resource ('connections'), and the phrase 'using the default connector style' distinguishes this from the sibling tool set_default_connector, which concerns styles rather than creation.

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 implies usage for creating connections with the current default style, but it does not explicitly state when to use this tool versus alternatives like set_default_connector, nor does it mention any exclusions or prerequisites. The reference to 'default connector style' is an indirect hint rather than explicit guidance.

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