loadTypes

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

Annotations already indicate a safe read operation; the description adds meaningful context about what is returned (accepted object types and their templates) and how it is used ('what a wrong objtype is checked against'). This goes beyond the annotation-only picture.

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 compact sentence that conveys the essential resource and purpose. The dash-connected clause is slightly awkward and elliptical, but it adds clarifying context without redundancy.

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?

For a zero-parameter read-only lookup, this is adequately complete: it explains what the tool returns and why an agent would use it. The lack of an output schema is partially mitigated by the descriptive content, though the exact response shape is not specified.

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 and the schema is fully covered by its empty properties definition, so the description does not need to document parameters. The baseline of 4 applies because there is no parameter ambiguity to resolve.

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 identifies the resource clearly: object types accepted by creation endpoints, plus their templates and validation role. It lacks an explicit verb, but the tool name 'loadTypes' supplies the action, and the 'creation endpoints' qualifier distinguishes it from the broader sibling 'objectTypes'.

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?

Usage is implied rather than stated: the description suggests this tool is relevant when working with creation endpoints or validating an objtype. However, it gives no explicit guidance about when to prefer loadTypes over similar siblings like objectTypes or objectStructure.

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