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

Annotations already declare readOnlyHint=false, idempotentHint=true and destructiveHint=true, so the safety profile is partly covered. However, the description adds nothing behavioral: it does not explain the destructive implication (e.g. whether omitted fields are cleared), how id selects update vs create, or any auth/ownership requirements. The sentence is a field inventory, not behavioral context.

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?

A single efficient sentence with no filler, and the core resource (business address) is front-loaded before the field enumeration. It is not bloated, though the enumeration style means the most decision-relevant facts (upsert semantics, required key) are absent rather than the sentence being too long.

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 an 18-parameter mutation tool with no output schema and no schema-level descriptions, the description is thin: it omits the create-vs-update mechanics tied to id, the required ivr_config_id, the destructiveHint implication, and any return information. It covers the field vocabulary but not the information an agent needs to call it correctly.

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 0% across 18 parameters, so the description must carry the load. It does translate many fields into plain language (address, directions, parking, public transport, accessibility, contacts, coordinates, timezone), but omits id, name, city, region, postal_code, country_code, is_primary and the required ivr_config_id, and never identifies which parameter is mandatory or how id drives the upsert.

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 verb-plus-resource idea is present ("Stores a business address plus..."), but it never states that this operates on a receptionist location, nor that it is an upsert (create-or-update). With siblings like upsert_receptionist, upsert_receptionist_profile and upsert_receptionist_knowledge in the list, the description gives an agent no basis to distinguish this tool from those.

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 mention of when to prefer upsert_receptionist_profile or the other upsert_receptionist_* siblings, and no prerequisites such as needing an existing ivr_config_id. Usage must be entirely inferred.

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