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

No annotations are provided, so the description carries full burden. It states 'update' implies mutation but doesn't disclose behavioral traits like required permissions, whether changes are reversible, error handling, or side effects. For a mutation tool with zero annotation coverage, this is a significant gap in transparency.

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 a single, straightforward sentence with no wasted words. It's front-loaded and efficiently states the core action. However, it's overly concise given the tool's complexity, missing necessary details that would make it more helpful.

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 tool's complexity (mutation with nested parameters, no annotations, no output schema), the description is incomplete. It doesn't cover parameter usage, behavioral context, or output expectations. For a knowledge graph update tool, this leaves critical gaps in understanding how to invoke it correctly.

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%, and the description provides no information about parameters. The input schema includes nested properties like name, type, and metadata, but the description doesn't explain what these mean or how to use them. With 1 required parameter and complex nested structure, the description fails to compensate for the lack of schema documentation.

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 verb ('update') and resource ('existing transportation in the knowledge graph'), which provides a basic purpose. However, it's vague about what 'update' entails and doesn't differentiate from sibling tools like update_artifact or update_currency, which follow the same pattern. It's functional but lacks specificity about the domain or scope.

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. The description doesn't mention prerequisites (e.g., needing an existing transportation to update), exclusions, or comparisons to sibling tools like add_transportation or delete_transportation. It's a generic statement with no contextual direction.

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