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

No annotations are provided, so the description carries the full burden, and 'Check' does convey a read-only, predicate-like behavior. However, it does not disclose what the result means, whether the check is local or network-backed, or how 'scope' and 'role hints' are determined. There is no contradiction with annotations because none exist.

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 with no filler; the verb and object appear immediately. It could convey more information without hurting readability, but as written it is appropriately compact and clear.

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?

Complexity is low (one parameter, output schema present), and the description correctly focuses on the availability predicate rather than return values. The clear gap is the missing definition of 'scope' and 'role hints' and the relationship to sibling catalog/auth tools, which an agent would need to infer from 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?

Schema description coverage is 0%, so the description must carry parameter meaning, but it only gestureally implies that tool_name identifies the tool whose availability is checked. It does not clarify the expected format, whether names come from the tool catalog, or any constraints on the value. The single required parameter remains under-documented.

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 ('Check') and a concrete object ('whether a tool is available'), and it adds the conditioning context of 'current scope and role hints.' This distinguishes it from sibling listing and auth tools by topic, though it never names an alternative explicitly. Without that explicit sibling differentiation, it stops short of a 5.

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 wording implies usage in a pre-invocation availability check tied to the current auth scope, but it never states when to prefer this over list_tool_catalog, auth_status, or list_capabilities, nor when not to use it. The usage context is present, but the guidance relies on inference rather than explicit direction.

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