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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint=false and destructiveHint=false, so the safety profile is fully covered. The description adds useful content scope (cities, example neighbourhoods, per-city page URLs), but says nothing about completeness, ordering, or how the optional language argument changes results.

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 compact sentence with the geographic scope and payload front-loaded and no filler. Every clause (cities, neighbourhoods, page URLs) contributes distinct information.

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?

With no output schema, the description usefully previews the return shape (city names, example neighbourhoods, page URLs). For a zero-required-parameter read-only list tool this is close to sufficient; only result ordering or completeness guarantees are absent.

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 100%, so the single 'language' enum (en default, fa) is already fully documented in the schema. The description adds no parameter meaning of its own, which matches the baseline 3 for a well-documented single-parameter tool.

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 resource (cities in Greater Vancouver served by Kay1 Electric) plus the payload contents (neighbourhoods and page URLs), which is enough to tell it apart from list_services and get_page. It does not explicitly name a sibling, so it falls short of a 5.

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?

Usage is only implied: an agent can infer it should call this to discover which cities are covered. There is no statement of when to prefer this over get_page or list_services, and no prerequisites or exclusions are given.

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