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

Annotations already establish readOnly, idempotent, non-destructive, and closed-world behavior, so the safety profile is covered. With no output schema, the description usefully carries the return-value burden by itemizing what the profile contains, though it says nothing about auth requirements, missing-slug failure behavior, or payload size.

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?

One dense sentence that front-loads the payload contents; every listed item maps to a real section of the profile. It is slightly list-heavy but wastes no words on boilerplate.

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 read-only tool with no output schema, the description adequately conveys what comes back and where it fits in the order/quote/book flow. The remaining gap is the undocumented slug parameter and the lack of sibling differentiation, both relatively minor given the annotations carry the safety profile.

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 0% — the single required 'slug' parameter is undocumented in both schema and description. The description never mentions the identifier at all, so it fails to compensate for the coverage gap by explaining how a slug is obtained or formatted.

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 makes the resource clear — a single business's full agent-readable profile — and enumerates the payload (identity/license, services with prices, hours, zips, delivery rules, policies, next actions). However it never states an explicit retrieval verb and does nothing to distinguish itself from siblings like get_services, get_service_requirements, or search_businesses.

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 explicit when-to-use or when-not-to-use guidance, and no mention of how this differs from get_services or search_businesses. The phrase 'exactly how to act (order, quote, or book)' only implicitly signals that this is the discovery step before place_order/request_quote/book_slot, leaving the routing to inference.

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