v0.4.0Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare the tool as read-only, idempotent, non-destructive, and not open-world, so safety behavior is covered. The description adds that the value is an annual range in AED, but it does not disclose source, freshness, coverage assumptions, or limitations.
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 description is a single front-loaded sentence with no wasted words. For a simple lookup tool, this is appropriately concise.
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?
Given the simple two-parameter input, full schema coverage, annotations, and an output schema, the description is largely complete for calling the tool. The main omissions are provenance/freshness and explicit sibling-tool routing, which are secondary for this straightforward estimate.
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 100%, and the area and bedrooms parameters are already well documented in the schema. The description restates both parameters but adds no extra syntax, constraints, or interpretation beyond the schema.
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 states a specific resource and metric: annual rent range in AED for an area and bedroom size. It is clear what the tool returns, though it does not explicitly differentiate itself from rental-related siblings such as dld_search_rent_contracts or rera_rent_increase.
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 by the description: estimate rent for a given area and bedroom size. However, there is no explicit guidance on when to use this versus alternatives or when not to use it.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
