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

Annotations already declare readOnly, idempotent, non-destructive and closed-world behavior, so the safety profile is covered. The description adds genuinely useful context beyond that: the response is Markdown with figures, limits and a citation line, sourced from daily-updated Dubai Land Department open data under CC BY 4.0.

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 purpose and id format are front-loaded in the first sentence with no wasted lead-in. The trailing data-licensing sentence is useful context but slightly tangential to the call itself.

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 compensates by naming the return fields (id, title, text, url, metadata) and the response format. For a single-parameter read tool this is essentially complete; only the sibling-routing question remains open.

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 carries the full burden and does so well: it defines the single 'id' as 'type:slug', gives a concrete example, and enumerates the valid type prefixes (project, community, developer, area), effectively supplying the enum the schema lacks.

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 ('Fetch the full readable record') and the resources it operates on (project, community, developer, area) by id. It is clear what it does, but it never contrasts itself with the close sibling get_entity, leaving the agent to guess which one to call for entity data.

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 implied through the id format example ('type:slug', e.g. 'community:dubai-marina') and the note that the text matches the datadubai.ae page, but there is no explicit when-to-use or when-not guidance and no mention of alternatives such as get_entity or search.

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