-]v0.15.0v0.14.0v0.12.1Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full behavioral burden. It discloses the meaningful precondition that entities must already exist and that the operation is a batch mutation, but says nothing about atomicity (partial vs all-or-nothing on failure), required permissions, or duplicate handling.
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?
A single front-loaded sentence with no filler. Every clause (multiple, typed, existing entities, one batch) contributes to correct invocation.
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?
For a batch mutation tool with no annotations, no output schema, and 0% schema coverage on top-level params, the description is too thin. Failure semantics, permissions, and return behavior are all absent.
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 three top-level parameters, and the description adds no meaning for user_id, source_id, or the relationships array shape. It does not compensate for the coverage gap, leaving required inputs like source_id unexplained.
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?
States a specific verb and resource (create... relationships) with clear scope: multiple, typed, existing entities, one batch. The batch framing implicitly distinguishes it from the sibling create_relationship, though it never names that sibling explicitly.
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 phrase 'in one batch' implies the tool is for bulk creation rather than single links, and 'between existing entities' hints at a precondition. However, it never states when to prefer this over create_relationship or what to do if an entity does not yet exist.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
