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

No annotations are provided, so the description carries the full burden. 'No setup' and 'works in any LLM chatbot' say something about operational prerequisites, and 'prompt and operating playbook' implies a static text return rather than a mutation, but nothing states the output shape, length, or whether the optional query changes behavior.

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 leading sentence ('Save hours every week') and 'battle-tested'/'No setup' are pure sales framing that consume the front-loaded position where the actual function should be. Removing the hype would leave almost no content.

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-optional-parameter tool with no annotations and no output schema, the description should at minimum say what the caller receives and how the optional query is used. Instead it leaves the return value undefined and the domain scoping ('restaurant/brand growth') only implied.

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% with a single optional 'query' parameter that the schema already documents as scoping the analysis. The description adds nothing about how the query is interpreted, 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 text is marketing copy ('Save hours every week', 'battle-tested') rather than a statement of what the tool does. It hints that the tool supplies 'a prompt and operating playbook for restaurant/brand growth', but never says what an invocation produces or how it differs from siblings like boss-decision-tool or brand-fnb-playbook.

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 when-to-use guidance, no exclusions, and no named alternative. The only contextual claim is 'works in any LLM chatbot', which describes portability rather than the situations that should trigger this tool over its many neighbors.

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