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

Annotations already declare readOnlyHint=false, destructiveHint=true, openWorldHint=true, and idempotentHint=false, so safety is covered. The description adds nothing about permissions, whether the board is shared/published by default, or what happens if parent_board_id is invalid — leaving real gaps for a mutating tool.

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?

It is a single short fragment with no wasted clauses, but it is under-specified rather than truly concise and lacks a leading verb to anchor the reader.

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 simple two-parameter create tool with full schema coverage and annotations present, the description is adequate but thin: it does not say what is returned (e.g., the new board's ID) or how the created board is scoped for sharing. No output schema exists to cover return semantics.

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 100%, and the schema already documents both title and parent_board_id including the 'Default: your Home' behavior. The description's mention of Home versus nesting mirrors the schema but adds no syntax or format detail beyond it, so baseline 3 applies.

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 names the resource (a new board) and its placement (Home root or nested under a parent board), which is enough to distinguish it from rename_board, duplicate_board, and list_boards. It is a sentence fragment without an explicit verb, relying on the tool name and title to supply 'create'.

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?

There is no statement of when to use this versus siblings such as duplicate_board (copy an existing board) or list_boards, and no prerequisites or exclusions are given. The only routing hint is implicit in the placement wording.

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