schema_test_to_measurement_hierarchy

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

Annotations already declare readOnlyHint=true, and the description does not contradict that. It adds useful traversal semantics (AoTest -> AoMeasurement via 'children'), but it does not disclose additional behavior such as recursion depth, ordering, empty-result behavior, or whether intermediate nodes are included.

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?

A single, front-loaded sentence conveys the operation without filler. Every word contributes to identifying the resource, endpoints, and relation.

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 zero parameters, an output schema, and a read-only annotation, the description is nearly complete for invocation. It fully specifies the traversal path, though it could strengthen completeness by adding when to use it relative to sibling schema tools.

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, so parameter semantics are not applicable and the baseline of 4 applies. The description has no parameter information to add because none exist.

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 states a specific verb ('Get') and resource ('hierarchical entity chain'), and identifies exact start and end entities ('AoTest' to 'AoMeasurement') plus the relation ('children'). This clearly differentiates it from more generic sibling tools like schema_get_entity and schema_list_entities.

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 use case is implied: call this when you need the AoTest-to-AoMeasurement hierarchy via the children relation. However, it does not explicitly state when to prefer this over alternatives, nor does it mention any exclusions or when-not-to-use conditions.

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