bookshelf_list_log_file

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

The readOnlyHint annotation already indicates this is a safe read operation, but the description adds no behavioral context beyond that. It does not disclose whether the tool returns a list of file names, file contents, or additional metadata, nor does it mention any filtering or pagination 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?

The description is a single concise sentence with no wasted words, but it is under-specified. It does not elaborate on the resource's scope or output, making it less useful than it could be while still being 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?

Given the output schema and readOnlyHint, the description could be minimal, but the ambiguity between 'list log file' and the sibling tools makes it incomplete. An agent would not know whether to expect a file list, a single file's contents, or which log file is referenced, so additional context is needed.

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 0 parameters, so the baseline for this dimension is 4. The description does not need to explain parameters that do not exist.

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 'List log file' clearly identifies the verb and resource, but it lacks scope. It does not distinguish between listing log file metadata, log file contents, or log file names, especially given siblings like 'bookshelf_list_log' and 'bookshelf_list_log_file_update'.

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 vs alternatives. The description does not mention 'Use for listing log files, not log entries' or any context that would help an agent choose this over 'list_log' or 'list_log_file_update'.

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