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

Annotations already declare readOnly, idempotent, non-destructive, open-world, but the description adds genuinely new context: public unauthenticated access and a 60 requests/min per-IP rate limit. Its weakness is the generic return statement ('matched records or computed metrics, canonical action URLs') which reads as boilerplate rather than describing this tool's actual payload.

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?

The core content and alternatives are front-loaded and useful, but the sentence 'Call this tool when you specifically need to execute get_studio_info on Bump to Baby Store' is tautological filler that restates the name, and the Returns sentence is generic padding.

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 zero-param read tool with no output schema, the description covers scope, access model, rate limits, and roughly what comes back. It stops short of naming the actual response fields (address, hours, phone) which would fully close the loop.

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?

With zero parameters the baseline is 4, and the description correctly confirms it is a zero-argument query, matching the empty schema. No further parameter semantics are possible.

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?

States a specific verb (Retrieve) and resource (official studio information) and enumerates the exact content: location, hours, phone, email, amenities, and elective scan philosophy. This is clearly distinguishable from siblings like pricing or FAQ tools.

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?

Explicitly gives a when-to-use condition and an explicit when-not-to-use rule naming the three alternative tools (get_scan_packages_and_pricing, get_gestational_guide, check_booking_availability). Nothing is left to inference.

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