generate_id

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

The readOnlyHint annotation already communicates that nothing is mutated, so the description does not need to restate that. It adds useful behavioral detail: IDs are unique, dashless, UUID v4, and multiple can be generated at once. No side effects or hidden requirements are disclosed, but none are evident.

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 that states the action, the resource, the multiplicity, and the format with zero filler. Every word earns its place.

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?

The tool is simple, the one parameter is fully documented in the schema, and the readOnlyHint covers the safety profile. The main gap is that, with no output schema, the description does not state the exact return shape (e.g., a single string vs an array of strings) for the generated IDs.

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 100% for the single optional 'count' parameter, so the schema already documents it. The description's 'one or more' loosely mirrors the count parameter but adds no parameter-level details beyond what the schema provides, so it meets the baseline without elevating it.

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 a specific verb ('Generate'), a concrete resource ('Geo knowledge graph IDs'), and a distinguishing format ('dashless UUID v4'). It also conveys multiplicity ('one or more') and uniqueness, making it easy to tell apart from sibling tools by name and function.

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 implies the tool should be used whenever new IDs are needed, but it never explicitly states when to use it, when not to use it, or how it relates to alternatives such as get_system_ids. For such a simple utility the purpose is clear, but the guidance is only implied.

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