bilibili_shutdown

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

With no annotations, the description carries the behavioral burden. It states the server will be stopped and provides the return format, but it does not mention side effects or irreversibility. The confirm parameter is defined in the schema rather than elaborated in the description.

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 and front-loads the core purpose in the first sentence. The return format and example are brief, useful additions with no filler.

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?

The tool has a single parameter, a complete input schema, and an output schema. The description covers purpose, return shape, and a concrete invocation example, leaving nothing essential missing for an agent to call it correctly.

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 coverage is 100%, so the confirm parameter is already fully documented as 'Must be True to shut down the server.' The description adds only a usage example, which reinforces but does not significantly expand the schema's semantic content.

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 identifies the action as 'gracefully stop' and the resource as 'the bilibili-mcp server.' This is unique among sibling tools, which are all content/account operations, so there is no ambiguity about what the tool does.

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 intended use is implied by the description: call this when you need to shut down the bilibili-mcp server. No explicit when-not-to-use or alternative tool guidance is provided, but no sibling tool performs shutdown, so the routing is straightforward.

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