list_classes

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

With no annotations provided, the description carries the full behavioral burden, yet it only restates the resource. It says nothing about pagination behavior, default limits, ordering, or whether the listing is scoped to the current binary/address context.

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?

It is a single short sentence and front-loaded, so there is no wasted text. But at this length it is under-specified rather than concise — the parenthetical is the only substantive content, and it does not compensate for the missing usage and parameter guidance.

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?

An output schema exists, so return values need not be explained. Still, for a tool with two undocumented pagination parameters, no annotations, and an ambiguous sibling, the description leaves too much unspecified to invoke it confidently.

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% for both limit and offset, and the description adds no meaning for either parameter — no default values or units (full list vs. page). The schema names alone do not convey whether these are required or how they interact.

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 verb (list) and a resource (class namespaces), and the parenthetical clarifies the output form (fully qualified names). However, it does not distinguish itself from the close sibling 'list_namespaces', leaving the agent unsure which of the two namespace-listing tools to choose.

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 when-to-use guidance, no mention of the pagination model (limit/offset), and no routing advice against adjacent siblings such as list_namespaces or list_functions. The agent must infer the use case entirely.

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