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

readOnlyHint=true already establishes the read-only safety profile, so the description's added burden is small. It contributes the upstream endpoint (Buildium: GET /v1/associations) and the shape of returned records, but says nothing about default result volume, paging behavior, or empty-result handling beyond what the schema's limit/offset already state.

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: the resource and returned fields are front-loaded, followed by the endpoint. No filler, no repetition of schema content.

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?

With 100% schema coverage, no output schema, and a readOnlyHint annotation, the main missing piece would be the return shape — and the description partially covers that by naming the fields each association carries. Only the pagination/volume characteristics of a 9-parameter list call go unaddressed.

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%, so all nine parameters (ids, limit, offset, status, orderby, location, last_updated_from/to, operating_bank_account_ids) are already documented with formats and defaults. The description adds no filtering, sorting, or paging semantics, so the baseline 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 clear verb ('List') and specific resource ('community/HOA associations'), plus the fields the records carry (address, manager, reserve, fiscal year, operating bank account). No sibling does this resource, so an agent can select it unambiguously without opening the schema.

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 — 'list associations' tells the agent this is the retrieval path for association data, but there is no explicit when-to-use guidance, no prerequisites, and no named alternative or exclusions. Adequate but with a clear gap.

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