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

No annotations are provided, so the description carries the full behavioral burden. It usefully discloses no auth required, rate limiting, keyword search scope, and required non-empty `q`, but omits return shape, pagination, error behavior, and what 'active' 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?

Three short sentences, front-loaded with purpose. The auth/rate-limit and required-parameter clauses are compact and no sentence is filler; structure is highly efficient.

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?

For a simple public search endpoint with no output schema and no annotations, the description covers auth, rate limiting, scope, and required `q`. It still leaves the `limit` behavior and result shape undocumented, so an agent lacks complete guidance for pagination and result handling.

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 50%; `q` is already documented in the schema as non-empty, and the description only restates that it is required and non-empty. The `limit` parameter gets no explanation in either the schema or the description, so parameter semantics are weak overall.

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?

Specific verb 'Search' and resource 'active community boards', plus the search fields 'name/description'. This makes the purpose clear and distinguishes it from generic board listing, but it does not explicitly name an alternative sibling such as list_boards.

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?

Provides useful context as a public, auth-free, rate-limited endpoint and states that `q` is required and non-empty. However, it does not explain when to use this tool instead of list_boards, search_everything, or search_topics, nor does it set exclusions.

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