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

Annotations already indicate this is a write operation and not destructive. The description adds some context by requiring a 'connected Pinterest account', but does not disclose side effects, defaults, duplicate handling, or external behavior. 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 clear, front-loaded sentence. It wastes no words and communicates the core operation immediately.

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?

For a create tool with no output schema, the description is under-specified. It does not explain what happens after creation, whether the created board is returned, default privacy behavior, or failure scenarios. The schema covers required fields, but the description leaves important operational context missing.

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 0% schema description coverage, the description must compensate, but it only hints at accountId via 'connected Pinterest account' and name via 'board'. It provides no meaningful guidance on privacy, description, or how these fields interrelate.

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 states a specific verb and resource: 'Create a new Pinterest board for a connected Pinterest account.' It clearly distinguishes this from sibling tools like pinterest_list_boards by emphasizing creation rather than listing.

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?

Usage is implied by the verb 'Create', and the phrase 'connected Pinterest account' hints at a prerequisite. However, the description does not explicitly state when to use this tool versus alternatives, nor does it mention when not to use it or any fallback options.

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