bookshelf_shutdown

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

Annotations already indicate a mutating (readOnlyHint=false) and non-destructive (destructiveHint=false) operation. The description adds only the minimal fact of shutting down, with no detail on side effects like interrupted operations or recovery. It provides little beyond the annotations.

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 short sentence with the action front-loaded. It is appropriately concise for a zero-parameter tool, though slightly terse.

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?

Given the simplicity of the tool, annotations and output schema present, the description adequately conveys the core purpose. It misses potential side-effect context, but for a straightforward shutdown operation this is largely sufficient.

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 tool has zero parameters, so the baseline of 4 applies. The description correctly needs no parameter details and the empty schema covers the absence of arguments.

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 uses the specific verb 'Shut down' and clearly identifies the resource 'Bookshelf service'. It unambiguously distinguishes this tool from siblings like bookshelf_restart or bookshelf_ping.

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 given on when to use this tool versus alternatives, nor are any prerequisites, exclusions, or warnings mentioned. The description simply states the action without contextual usage advice.

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