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

Annotations already declare the safety profile (readOnlyHint=false, destructiveHint=false, openWorldHint=false), so the description's remaining burden is light. It adds context annotations do not carry: the board is created empty and the result returns an id and link, which is genuinely useful given there is no output schema. It omits auth/permission or quota considerations, but for a simple creator that is a minor gap.

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?

Two short sentences with zero filler, front-loaded with the action and outcome. Every clause earns its place.

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 one-parameter creation tool with annotations covering safety and no output schema, the description supplies the essentials: what is created, its initial state, and what is returned. Only optional context like permission requirements or how to subsequently populate the board is 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?

Schema description coverage is 100%, so the single 'title' parameter and its maxLength of 120 are fully documented in the schema. The description adds no extra meaning about the title (e.g., uniqueness or naming conventions), so the baseline of 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?

Clear specific verb and resource: 'Make a new, empty Flett board'. It conveys the created object's state (empty) and its intended use ('for a new topic'), which distinguishes it from sibling mutations like add_block or edit_block. It stops short of explicitly naming the complementary sibling list_boards, so sibling differentiation is implied rather than stated.

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 phrase 'for a new topic' implies the usage context (starting a fresh board rather than populating an existing one), which is more than nothing. However, there is no explicit when-to-use/when-not guidance, no mention of prerequisites, and no routing to alternatives such as list_boards for finding existing boards.

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