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

No annotations are supplied, so the description carries the full burden, and it discloses almost nothing: it does not say what the tool returns, whether it mutates state, whether it requires licensing/auth, or how it handles the optional query. 'Save hours every week' and 'no setup' are marketing claims, not behavioral facts an agent can act on.

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 no bloat, which is good, but the front-loading is spent on a benefit claim ('Save hours every week') rather than on what the tool does. The information that matters is buried in the second half.

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 zero annotations and no output schema, the description should explain the return artifact and invocation behavior. Instead it leaves the deliverable's format, length, and domain unresolved, and never resolves the clash between the name and the described restaurant-growth subject matter.

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 coverage is 100% for the single optional 'query' parameter, so the schema already explains scoping. The description adds no meaning beyond it and in fact says 'no setup', which implicitly downplays any input at all. Baseline 3 applies since the schema does the work.

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 states a deliverable ('a battle-tested prompt and operating playbook for restaurant/brand growth'), which is at least a concrete verb+resource, but it collides head-on with the tool name 'sleep-fixer' and with siblings like sleep-fixer-lite, sleep-apnea-guide and baby-sleep-planner. An agent reading name plus description gets two unrelated domains with no way to reconcile 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?

There is no when-to-use guidance at all: nothing tells the agent whether to call this instead of brand-fnb-playbook, sanhao-ops-diagnostic, or sleep-fixer-lite. 'No setup, works in any LLM chatbot' is promotional positioning, not a selection rule.

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