get_property_value

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds dotted-path behavior and broad 'any object' scope, but it does not disclose behavior on invalid paths, errors, or return formatting. This is acceptable for a simple read tool but not rich behavioral 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?

The description is brief and front-loaded with the core action. The bilingual repetition is somewhat redundant but serves a multilingual audience without bloating the text. Every substantive piece of information appears once per language.

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 two-parameter read-only tool with full schema coverage and no output schema, the description is largely sufficient. It explains the dotted-path mechanism and positions the tool alongside get_class_properties. It stops short of describing return values or edge cases, but the tool is simple enough that the gap is minor.

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 coverage is 100%, so the schema already documents both parameters clearly. The description adds the dotted-path example 'material.diffuse', which is helpful, but it does not significantly extend the semantics beyond what the schema already states. Baseline 3 is appropriate.

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 a specific verb and resource: read any property value of any object, with dotted path support. It mentions get_class_properties as a companion, which hints at a distinct role, but it does not explicitly contrast this tool with that sibling or other getters.

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 clear context: it is for arbitrary property reads and is intended to be used together with get_class_properties for parameter reads. It does not explicitly state when not to use it or name alternatives, but the usage context is reasonably clear.

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