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

The annotations already declare readOnlyHint, idempotentHint and openWorldHint=false, so the safety profile is covered. The description adds genuine behavioral context beyond that: the ordering rule ('sorted by project count') and the aggregate fields returned. It does not mention silent truncation at the 300 limit, which is the one remaining gap.

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 sentence with zero filler: the resource, the payload fields, and the sorting are front-loaded, and the optional filter clause comes last. Nothing needs trimming.

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 two-parameter read-only listing with annotations covering safety and no output schema, the description is nearly complete: it says what is listed, what each item contains, and the order. It stops short of noting that results are capped and truncated at the limit, which matters when there is no pagination parameter.

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 100%, so both parameters (limit range 1-300 with default 25, and query as an optional name filter) are already fully documented in the schema. The description only restates the optional name filter and adds no syntax, matching behavior, or limit interaction details, so the baseline 3 applies.

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 names a specific verb and resource ('List Dubai communities') and states exactly what each result carries (project counts, lowest starting price) plus the sort order. Plural-listing versus the singular get_community sibling is unambiguous from the name alone.

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?

It states that the name filter is optional and how results are ordered, which implies a browse-all use case. However, it never says when to prefer it over siblings like get_community for details or search_projects, and it gives no exclusion or prerequisite guidance.

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