B3.1/5.0

Behavior3/5

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

Annotations already establish read-only, idempotent, non-destructive behavior, so the safety burden is offloaded. The description adds genuinely useful non-schema context — the KHDA source, that uniform data is currently paused, and the year/grade distinction. It says nothing about pagination via cursor or result limits, which is the remaining behavioral gap.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Very short and front-loaded: domain first, then parameter hints, then caveats. The telegraphic fragment style ('uniforms paused') saves space but slightly sacrifices clarity, and 'bus fees, distance' is awkwardly spliced into the domain sentence.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

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 are covered, but for a 12-parameter, 0-required query tool with 17% schema coverage the description is far too sparse. Most filters and the pagination parameter are left for the agent to infer from bare property names.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 17% across 12 parameters, so the description must carry the load but does not. It clarifies only q, near (zone, not school), and school_id (detail mode), while area, sort, grade, cursor, rating, page_size, radius_km, curriculum, and max_fee_aed are undocumented in both schema and description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description names a concrete resource and data domain: Dubai (KHDA) school fees, tuition by grade/year, bus fees, distance. There is no sibling school tool in the list, so no explicit differentiation is needed, but the tool's own action ('look up/report school fees') is only implied by the noun phrase rather than stated with a verb.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives parameter-selection hints ('q: school name; near: zone; school_id: detail') and two important caveats ('Year ≠ Grade', 'uniforms paused'), which imply usage. However, it never states when to use this tool versus another, nor explains how the parameter modes interact (e.g. that school_id returns detail and conflicts with list-style filtering).

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