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

No annotations are supplied, so the description must carry the full behavioral burden; it only asserts equivalence to another tool and says nothing about whether the call is read-only, what it returns, or whether it has side effects. The word "controller" does not clarify behavior.

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?

One short sentence with a parenthetical, front-loaded and free of filler. The only inefficiency is the vague word "controller", but it does not add bulk.

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?

With no output schema and no annotations, the description should explain what a "starter" is and what the tool returns, but it provides only an alias to get_starter. An agent unfamiliar with the sibling cannot know the return value or usage constraints.

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 input schema has zero parameters, so the baseline is 4; the description adds no parameter meaning because there is nothing to parameterize. No additional semantic detail is needed.

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 identifies the resource as the submarine-theater starter controller and explicitly equates it to get_starter with theater "sub", which distinguishes it from the sibling get_starter. However, "controller" is vague and the description never plainly states that it retrieves a starter configuration, so the purpose is clear mainly by reference.

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 parenthetical implies this is the submarine-theater variant and points to get_starter with a theater argument as the general form, but it never states when to choose this tool over get_starter, get_started, or other starter-related siblings. There are no exclusions or preconditions.

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