Ucontrol Read Umap Components

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint=false. The description adds no behavioral context beyond the bare action, such as what data is returned, pagination, or implications of the 'open world' hint. It does not contradict annotations, but it also does not add value beyond them.

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 one short sentence, immediately stating the action and scope. It is efficiently front-loaded with no filler or redundancy. For a zero-parameter list operation, this level of brevity is appropriate and 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?

Given the simple nature of the tool (no params, strong annotations), one might expect a minimal description to suffice. However, the term 'components' is vague, and with no output schema, the agent is left without any indication of what the returned list contains, how it is structured, or how this relates to sibling uMap entities. The description is too sparse to fully support correct usage.

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 tool has zero parameters, so the input schema is empty. According to the rubric, a baseline of 4 is appropriate when there are no params to describe. The description does not need to elaborate on parameter semantics, and it correctly avoids adding irrelevant information.

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 action ('list components') and the resource ('uMap API'), identifying the tool's purpose. It is not a mere tautology, but it does not differentiate 'components' from the many sibling uMap read tools, leaving some ambiguity about what exactly constitutes a component.

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 versus alternatives, no exclusions, and no mention of typical use cases. An agent receives no information about when to select this over the many other ucontrol_read_umap_* tools.

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