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

Annotations already declare readOnlyHint, idempotentHint and openWorldHint=false, so safety is covered. The description adds genuinely new context — result contents and deterministic sort by project count — but says nothing about pagination behavior, truncation at the limit, or whether counts reflect all projects or only active ones.

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?

Two tight sentences, zero filler, with the return contents and sort order front-loaded before the optional filter. Nothing is repeated verbatim from the schema beyond a brief echo of the filter.

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?

There is no output schema, so the description correctly takes on the job of describing the returned fields (project counts, off-plan vs ready, ordering) and does so adequately. A note on result pagination or what happens at the limit ceiling would make it fully complete.

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 `limit` and `query` are already documented in the schema. The description restates the name filter as "optionally filtered by name text" but adds no matching semantics (substring vs prefix, case sensitivity) or guidance on choosing a limit, so it earns only the baseline.

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 ("List Dubai developers") plus the payload it returns (project counts split off-plan vs ready) and the sort order. This cleanly separates it from get_developer by implication (plural list vs single record), though it never names that sibling explicitly.

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: the reader infers this is the browse/discovery entry point before drilling into get_developer. There is no explicit "use this when... instead use X when..." guidance, and no mention of whether an empty result set or a name miss behaves differently.

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