Services_getFixedSlotCapacity

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

With no annotations, the description carries the full burden of behavioral disclosure. It adds that this is a 'Catalog entry' and runs in the Kuudo deployment rather than here, which is useful, but it omits whether the tool is directly invocable, what authentication or prerequisites apply, and what the returned capacity data looks like.

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 only three short sentences with no wasted filler, and it front-loads the important 'Catalog entry' classification. The two deployment-related statements could be merged, but overall the length is appropriate for the limited schema context.

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?

This is a sparse description for a tool with no annotations and no output schema. It names the high-level capability and remote execution environment, but it does not explain what the capacity data represents, what a caller should do with the response, or whether this tool is meant to be invoked at all from the current context.

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 zero defined properties and 100% schema coverage, so the description has no parameter semantics to add. The baseline for zero-parameter tools is 4, though the schema's additionalProperties: true leaves some ambiguity about whether hidden parameters could be accepted.

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 says it 'Provides capacity in fixed-size slots,' which identifies a clear function and differentiates it from the sibling Services_getRangeSlotCapacity by the 'fixed-size' qualifier. It is not a pure tautology, though 'provides capacity' adds only slightly more specificity than the tool name.

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?

There is no guidance about when to choose this tool over alternatives such as Services_getRangeSlotCapacity or Services_getAppointmentSlots. The statement 'Runs in your Kuudo deployment, not here' hints at an environmental constraint but does not say when to use it or what conditions make another tool preferable.

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