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

No annotations are supplied, so the description carries the entire burden, and it discloses almost nothing: not whether the tool runs an analysis, returns a static prompt template, or produces a plan, and not what the caller receives back. The only behavioral hint is that the output is a "prompt and operating playbook," which is too vague for a tool with zero structured safety or output metadata.

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 sentences, but both are marketing copy — "Save hours every week" and "No setup, works in any LLM chatbot" — rather than function. The space that should be front-loaded with purpose is spent on benefits, so brevity here reflects under-specification, not concision.

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 even a one-parameter tool, the definition leaves the core question unanswered: what does invoking it produce? With no annotations and no output schema, the description is the only source of behavioral context, and it supplies none — compounded by the fitness-versus-restaurant domain mismatch.

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 already documented at 100% schema coverage, so the schema does the explanatory work and the baseline applies. The description adds nothing about how the query scopes the analysis, but it is not required to given full coverage.

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 never states a concrete verb+resource for the tool itself; it advertises "a battle-tested prompt and operating playbook" without saying what task it performs. Worse, the name and title say fitness/diet coaching while the body claims it is for "restaurant/brand growth," leaving the agent unable to tell what domain this actually serves or how it differs from siblings like fatloss-meal-planner or fnb-store-diagnostic.

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?

"No setup, works in any LLM chatbot" is a convenience claim, not usage guidance. There is no when-to-use, no when-not-to-use, and no named alternative among the many diet and restaurant siblings an agent would have to choose between.

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