bookshelf_create_tag

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

The description adds the 'WRITE: this modifies your Bookshelf instance' warning, but this is largely redundant because annotations already include readOnlyHint=false. No additional behavioral details are disclosed, such as idempotency, duplicate handling, permissions, or side effects beyond modification.

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 extremely concise at two short sentences. The first states the purpose, and the second adds a relevant safety note. There is no redundant wording, and it earns its place by being front-loaded 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?

Although an output schema exists, the input side is a major gap. The single 'body' parameter is completely undocumented, and the tool description provides no context about what constitutes a valid tag or how to use the endpoint. For a creation tool with free-form input, this is inadequate for reliable invocation.

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?

With schema description coverage at 0%, the description must compensate for the undocumented 'body' parameter. However, it provides zero information about what fields are expected, what a tag consists of, or the shape of the request body. This leaves the agent completely in the dark about how to construct a valid call.

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 states 'Create tag' with a specific verb and resource. This distinguishes it from sibling tools like update_tag, delete_tag, and get_tag. Although terse, it is unambiguous and perfectly conveys the tool's function.

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 explicit guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, when to prefer create over update, or any exclusions. The only usage indication is the word 'create', which is implicit rather than instructive.

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