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

Annotations already indicate this is a mutating but non-destructive operation, and the description's mention of a 'connected' account adds a small amount of context about external side effects. However, it does not disclose details like creation limits, default privacy, or success/failure behaviors.

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, direct sentence with no wasted words. It is immediately understandable and front-loaded with the primary action.

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 four parameters, no output schema, and minimal parameter guidance, the description is too sparse to fully guide an agent. Missing details like privacy default, return value, and any preconditions for the connected account mean an agent must infer significant information.

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 description coverage is 0%, so the description must compensate for parameter meaning. It weakly implicates accountId via 'connected Pinterest account' and name via 'new board', but it does not explain privacy or description parameters, and it does not clarify required input semantics.

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 a specific verb ('Create') with a specific resource ('Pinterest board') and scopes it to a connected Pinterest account. This clearly distinguishes it from siblings like pinterest_list_boards and create_post.

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 description implies use when a new Pinterest board needs to be created, but it does not name alternatives or provide when-not-to-use guidance. There is no explicit routing between this and sibling tools.

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