chamber_membership

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds substantive domain content (mandatory membership, AED 700–2,200 fee tiers) but discloses no behavioral traits such as data source, currency/freshness of rules, or whether fees are jurisdiction-specific.

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?

Three short sentences with the core action front-loaded and no filler. Size is appropriate for a knowledge lookup; only the slight redundancy of restating the DCDE/Dubai Chamber distinction keeps it from a 5.

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?

An output schema exists, so return values need not be explained, and the description is adequate for a simple no-param lookup. What is missing is any differentiation from the overlapping 'chamber_of_commerce_info' sibling, leaving the agent to guess which one answers a Chamber-membership question.

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?

The tool takes zero parameters, so there is nothing to disambiguate and the schema is trivially complete. Baseline 4 applies for a no-parameter tool.

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 first sentence gives a specific verb and resource ('Return Dubai chamber membership rules'), which is unambiguous. The follow-up sentences narrow the domain to Dubai Chamber of Commerce rather than DCDE. However, it never distinguishes itself from the very similar sibling 'chamber_of_commerce_info', which limits sibling differentiation.

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 note that 'DCDE has no standalone membership scheme' steers the agent toward Dubai Chamber, which is a useful routing hint. But there is no explicit statement of when to pick this over 'chamber_of_commerce_info' or any prerequisite/exclusion.

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