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

Annotations already declare readOnlyHint, idempotentHint, and closed-world scope, so safety behavior is covered. The description adds useful context that results are originally sourced commentary with linked citations, but says nothing about result ordering, limits, or what an empty result means.

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 short sentences, front-loaded with the resource and its provenance. The second sentence largely restates schema fields, which is mild redundancy but not enough to hurt readability.

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?

This is a simple, annotation-covered, no-output-schema search tool with fully described parameters, so the description is sufficient to invoke it correctly. It could be stronger with a note on result ordering or what distinguishes it from get_insight.

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%, with the enum category values and limit bounds fully documented in the schema. The description only restates the existence of text and category filters and adds no matching/format semantics; the baseline of 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?

States a specific verb and resource ('Search ... Dubai market insights') and adds scope detail (originally sourced commentary with linked sources). It does not, however, distinguish itself from close siblings like get_insight or ask, so an agent must infer the boundary.

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?

The phrase 'Filter by text and category' implies how to use it, but there is no explicit when-to-use versus get_insight (single insight lookup) or ask (conversational Q&A). Usage is only inferable.

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