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

Annotations already declare this is a non-read-only, open-world, non-idempotent, non-destructive mutation, so the safety profile is covered. The description adds the operator-only access requirement, which is real context beyond annotations. It does not disclose what happens to existing city data when the tool is invoked, so it remains thin for a mutation tool.

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 description is very short and wastes no words, but it is a fragmented noun-phrase list rather than a front-loaded statement of action. The most important information—what the tool does—is absent, so brevity here reflects under-specification rather than disciplined concision.

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 four-parameter mutation tool with no output schema and no schema descriptions, the definition is inadequate. It omits the action semantics (upsert vs create vs update), does not clarify the required 'city', 'name', and 'intro' parameters, and provides no return or error context. The operator gate is helpful but does not fill the gap.

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%, so the description must carry all parameter meaning. It names the fields but leaves the relationship between 'city' and 'name' unclear, and the phrase 'the city names its rows may use' is ambiguous rather than clarifying the 'city' parameter's format or role. It does not explain required versus optional fields or expected string formats.

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 identifies the resource as a city page and lists the fields it concerns (name, country, row city names, intro), which distinguishes it from print_shop_put. However, it never states the action—create, update, or upsert—so the agent must infer 'put' behavior from the tool name alone. The purpose is recognizable but vague.

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?

The only usage guidance is the audience restriction 'Operators only,' which is useful but is a role gate rather than a when-to-use rule. It gives no alternatives (e.g., print_shop_put, print_shops_in_city), no prerequisites, and no indication of when this should be called versus other print-related tools.

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