create_relations

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

The description discloses that duplicate relations are silently ignored, which is useful behavioral information. However, it does not mention error handling for non-existent entities or other side effects, leaving gaps.

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 concise with two sentences; the first states the primary purpose, the second adds crucial parameter details. No unnecessary information.

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 generic schema and presence of an output schema, the description adequately covers the input structure. However, it could mention validity of relation types or entity existence requirements for full completeness.

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 has 0% coverage, so the description is essential. It explicitly defines the required fields (from, to, relationType) and their types, compensating for the vague schema.

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 tool creates relations between entities in the knowledge graph, distinguishing it from sibling tools like create_entities or delete_relations.

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 does not provide explicit guidance on when to use this tool versus alternatives, but it implies usage for adding relations. No context on prerequisites or when not to use.

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