modx_create_property_set

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

With no annotations supplied, the description carries the full behavioral burden for a mutation tool yet says nothing about required permissions, name-uniqueness or duplicate handling, whether the set is immediately usable, or what is returned. The only behavioral hint is the shape of 'properties', which is really parameter detail.

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?

Two short sentences with the action front-loaded and no filler; the constraint on 'properties' is placed immediately after the purpose statement. Nothing is wasted, though the sentence budget is arguably too small for a four-parameter mutation tool.

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 a mutation tool with no annotations, no output schema, 0% schema coverage, and a nested object parameter, the description is materially incomplete. An agent would have to guess at the meaning of 'category', the structure of 'properties', and the permission requirements before calling.

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 0% across four parameters, so the description must compensate and largely fails: it clarifies only 'properties' as a JSON object of property definitions. 'name', 'description', and especially 'category' (a bare number, presumably an ID) remain ambiguous, and the nesting inside 'properties' is unexplained.

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 opens with a specific verb+resource, 'Create a property set,' which an agent can readily distinguish from modx_update_property_set, modx_get_property_set, and modx_list_property_sets by name alone. It does not explicitly call out the sibling boundary, so it stops short of a 5.

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 on when to create a new property set versus updating an existing one, no mention of prerequisites or permissions, and no reference to the related assign/unassign tools that would typically follow creation.

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