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

With no annotations, the description bears full responsibility for disclosing behavior. It only says 'check', implying a read-only operation, but does not specify what data is returned (e.g., logged in/out, account details, error conditions). The lack of output schema or further description leaves key behavioral traits unclear.

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 a single sentence with no wasted words. It is front-loaded with the core action and resource, making it easy to parse quickly.

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 tool with no parameters and no output schema, the description should at least hint at the expected return structure (e.g., 'returns a JSON with login status and account details'). The current description is too vague to fully inform an AI agent about what to expect, especially when sibling tools like login or get_subscription have richer context.

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?

There are no parameters, so schema description coverage is 100% by default. The description adds no parameter-level information, which is acceptable given zero parameters. The baseline score of 4 applies as there is nothing to improve.

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 the tool checks login status and account info. The verb 'check' and resource 'Crunchyroll login status and account info' are specific, and the tool name matches the purpose. It is well-differentiated from sibling tools like login, logout, and get_subscription.

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?

No guidance is provided on when to use this tool versus alternatives (e.g., check before performing authenticated actions). The description does not exclude any scenarios or mention prerequisites, leaving the agent without context on appropriate usage.

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