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

With no annotations, the description carries the full burden and does a solid job: it declares read-only behavior, explains that judgements and evidence retain their basis/scope, and denies the existence of an aggregate score. It omits details like authentication, locale effects, and exact return shape, but the essential behavior is transparent.

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, logically ordered from simplest invocation to deeper traversal, and uses code formatting effectively. Every sentence earns its place with distinct information rather than 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?

Given the absence of an output schema and annotations, the description covers the main traversal modes and return categories reasonably well. Still, the unexplained `locale` parameter, lack of a concrete example, and no mechanism for enumerating link names leave noticeable gaps for a 5-parameter tool.

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?

Because schema description coverage is 0%, the description must explain parameters, and it does for type, id, link, and direction. It even explains the no-arguments case. However, `locale` is entirely unexplained, which is a real gap for one of five parameters.

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 clear verb–resource pair ('Walk the VOLO Ontology') and enumerates the main output modes: types/link types, objects by type, and object details with links. It does not explicitly distinguish it from sibling tools like get_ontology, but the core function is unambiguous.

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?

It provides a concrete progression of invocation forms: no arguments, type, type+id, then link with direction. It also adds a guardrail by stating 'No aggregate score exists.' It does not name alternatives among the sibling tools, so explicit when-not-to-use guidance is missing.

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