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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds one genuinely useful behavioral guarantee — it will not fabricate a feature, number or landmark — but says nothing about output length, tone, or how missing fields (only city is required) are handled in the generated text.

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 front-loaded sentence with no filler, and the grounding constraint is placed where it will be read first. It is efficient, though for a 10-parameter tool the extreme brevity is arguably under-specification rather than conciseness.

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?

Ten parameters with zero schema descriptions and no output schema means the definition should explain what each input contributes and what shape the generated listing takes. Neither is addressed, leaving an agent to guess at the semantics of most fields and the format of the returned copy.

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% across 10 parameters, so the description carries the full explanatory burden. It only incidentally covers 'lang' by listing Arabic, English or French, and gestures at facts broadly; area, beds, baths, price, purpose, type, district and features all go unexplained in both schema and description.

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 and resource ('Writes a property listing description') plus the three supported languages, so the agent knows exactly what artifact is produced. It does not differentiate itself from siblings like publish_listing_page, which handles distribution rather than copy generation.

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 named alternative. The agent must infer that this is the copy-generation step before publishing, rather than being told to use property_listing_writer first and publish_listing_page afterwards.

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