add_transportation

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

With no annotations provided, the description carries full burden for behavioral disclosure but provides none. It doesn't indicate this is a creation/mutation operation, what permissions might be required, whether the transportation becomes immediately available in the system, what happens on success/failure, or any side effects. The passive 'represents' language obscures the actual action being performed.

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 extremely concise - a single sentence. While this is efficient, it's under-specified rather than appropriately concise. The sentence structure is clear but fails to convey necessary information about the tool's purpose and usage.

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 tool with 1 complex parameter (nested object with 4 required fields), 0% schema description coverage, no annotations, and no output schema, the description is completely inadequate. It provides no operational context, no parameter guidance, no behavioral information, and doesn't explain what happens after adding transportation or how to verify success.

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% (all parameter descriptions are generic like 'Additional property value' and 'Item in owner array'), and the tool description provides no parameter information whatsoever. The description doesn't mention the required 'transportation' object parameter, its structure, or what fields like 'name', 'description', 'owner', and 'type' should contain beyond what's minimally indicated in the 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 'Represents a transportation owned or used by a character or entity' is tautological - it restates the tool name 'add_transportation' in different words without specifying what the tool actually does. It doesn't indicate this is a creation/adding tool versus a representation/viewing tool, and doesn't distinguish it from sibling tools like 'update_transportation' or 'delete_transportation'.

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 about when to use this tool versus alternatives. The description doesn't indicate this is for adding/creating transportation versus updating existing transportation (update_transportation) or deleting it (delete_transportation). There's no mention of prerequisites, context, or relationship to other tools in the system.

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