bookshelf_get_config_metadataprovider_by_id

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

The annotation readOnlyHint=true already indicates a read operation. The description's 'Fetch' is consistent with that, but it adds no extra behavioral details such as error handling, auth requirements, or return specifics. It does not contradict 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, appropriately sized for a simple get-by-id operation. No filler words, but it is also minimal.

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?

With a simple parameter set, an existing output schema, and a readOnly annotation, the description is sufficient to convey the tool's function. It does not need to explain return values because the output schema exists, and there are no complex nested objects.

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 schema has one integer parameter 'id' with no description. The description confirms that the id is the identifier of the config metadataprovider, but it does not add constraints beyond the schema, nor does it explain where to obtain the id. The coverage is 0%, so the description only partially compensates.

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 'Fetch' with the resource 'config metadataprovider' and specifies 'single' and 'by id', clearly distinguishing it from sibling tools that list or update metadataproviders.

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?

It implies usage when you have a specific id and need one record. However, it does not explicitly name alternative tools like bookshelf_get_config_metadataprovider for listing, so guidance is implicit rather than explicit.

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