arango_add_vertex_collection

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

With no annotations, the description must convey behavioral traits. It does not disclose whether the operation is permanent, requires permissions, or has any side effects on existing graph structures.

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 very concise at one sentence, but it sacrifices detail. It lacks structure but no word is wasted. It could be improved without adding much length.

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 low schema coverage, no output schema, no annotations, and the tool's operation (modifying a graph), the description is completely inadequate. It does not explain return values, error conditions, or prerequisites.

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 coverage is only 33% (only 'database' has a description). The 'graph' and 'collection' parameters lack explanations, and the description does not add any meaning beyond the parameter names. The baseline for low coverage is higher, so this is insufficient.

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 states the action 'add a vertex collection to a named graph,' which is clear but vague. It does not specify whether it creates a new collection or associates an existing one, and it does not differentiate well from sibling tools like arango_create_collection or arango_add_vertex.

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 provided on when to use this tool versus alternatives such as arango_add_vertex or arango_create_graph. There is no mention of prerequisites, contexts, or exclusions.

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