set_hwp_property

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 indicates a mutation ('Set') but does not state permissions, side effects, whether the property must already exist, or what happens on invalid property names or value types. No behavioral context beyond the basic mutation is provided.

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 compact and front-loaded with the core purpose, followed by a two-line parameter list. Every sentence contributes necessary information and there is no filler or repetition.

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?

Although an output schema exists, the description is incomplete for a generic COM property setter. It does not enumerate which properties can be set, whether this tool is intended only for dynamic/low-level access, or how errors are handled. An agent has no way to know if a particular property_name is valid without external knowledge.

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%, so the description must compensate. It adds minimal semantic labels ('Property name to set', 'Value to assign') but provides no valid property names, value constraints, format expectations, or coercion behavior. This is only slightly more informative than the raw schema titles.

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: 'Set a property on HWP COM object.' The verb and resource are explicit, and the tool is immediately distinguishable from sibling tools like get_hwp_property by its setter purpose. No ambiguity about what this tool does.

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 gives no guidance about when to use this tool versus alternatives. It does not mention that this is a generic low-level setter, nor does it distinguish it from more targeted setters like set_engine_properties or set_view_properties. The agent must infer usage entirely from the name.

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