create_relations

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

With no annotations, the description carries the full burden for behavior disclosure. It only states that relations are created, but does not mention idempotency, overwrite semantics, validation of entity existence, transactional behavior, or what happens on partial failure. The mutation effect is implied but no further behavioral context is given.

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 two sentences with no redundancy. It front-loads the core action and purpose, then adds a concise stylistic guideline. Every word earns its place, making it highly efficient for an agent to parse quickly.

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?

This is a complex tool with a nested array of 13 fields, no annotations, and no output schema, yet the description offers only a high-level purpose. It lacks crucial context such as whether entities must already exist, how failures are handled, whether the operation is atomic, and what the tool returns. The sparse description is inadequate for an agent to use the tool safely and effectively.

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 the top-level parameter, yet the description does not explain the array structure of 'relations' or the required fields. It adds the active voice requirement for relationType, which is helpful, but this only partially compensates. The nested schema descriptions exist but are not referenced or clarified by the tool description.

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 multiple new relations) and the resource (between entities in the Memento MCP knowledge graph). It distinguishes from siblings like update_relation and delete_relations by focusing on creation, and the 'multiple' wording distinguishes it from any single-relation tool. The scope is unambiguous.

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 use for batch-creating relations ("multiple new relations"), but provides no explicit when-to-use or when-not-to-use guidance. It does not mention alternatives or exclusions, though sibling tool names like update_relation suggest the contrast. The 'active voice' note is a formatting guideline, not a usage context.

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