graph.category.update

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

With no annotations provided, the description carries the full burden of disclosing behavioral traits. It only says 'updates data' but does not specify whether fields are overwritten partially or fully, what happens if the category does not exist, or if there are any side effects. No return value or confirmation is described.

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 short sentence, which is concise but lacks the detail needed to be useful. It is front-loaded with the action but does not cover necessary information, making it less effective despite its brevity.

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 has 8 parameters, no output schema, and no annotations, the description is severely incomplete. It fails to explain parameter semantics, behavioral outcomes, or any constraints, leaving the agent with insufficient information to use the tool 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?

The input schema has 8 parameters with 0% description coverage, and the tool description does not explain any of them. The agent must rely solely on parameter titles like 'Id' or 'Name', which are insufficient to understand required formats, constraints, or how they relate to the update operation.

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 tool updates an existing category in the catalog. It uses a specific verb ('update') and resource ('category'), and the sibling tool graph.category.create implies the distinction. However, it is somewhat vague by saying 'data' rather than listing specific fields.

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 provides no guidance on when to use this tool vs alternatives like graph.category.create. There is no mention of prerequisites, conditions for updates, or when not to use it. The context from sibling tools implies the difference, but explicit guidance is absent.

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