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

No annotations are supplied, so the description carries the full burden. It hints that the payload is a 'prompt pack' with a prompt, usage guide, and edge-case handling, but never says whether the tool reads data, generates text, or returns a template, nor anything about return shape, side effects, or permissions.

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 short, but the length is spent on promotional filler ('in minutes', 'professional results') rather than the function. The sentences do not earn their place because none of them tells an agent what the tool does or when to call it.

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 tool with one optional parameter and no output schema, the description should at minimum explain what a 'board' deliverable contains and how it differs from analyze/diag/formula/tpl counterparts. It leaves both the output form and sibling differentiation unaddressed.

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?

There is a single optional 'query' parameter fully documented in the schema (100% coverage), so the schema carries the semantics. The description adds nothing about what a query scopes or how it changes output, which is the baseline expectation when schema coverage is complete.

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 restates the tool name ('This abtest board tool prompt pack') and wraps it in marketing language ('Turn expertise into output', 'produce professional results in minutes') without stating what the tool actually computes or produces. It never distinguishes 'board' from the sibling abtest-analyze-tool, abtest-diag-tool, abtest-formula-tool, or abtest-tpl-tool, so an agent has no basis for choosing among them.

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 only contextual hint is the audience ('restaurant and brand teams'), which is not a when-to-use condition. There is no statement of when this tool is appropriate versus the four sibling abtest tools, and no prerequisites or exclusions are given.

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