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

Goes beyond the readOnlyHint/openWorldHint annotations by disclosing the matching rule: every keyword must match name, description or category, which is AND semantics rather than the OR an agent might assume. It does not mention pagination behavior or result ordering, but for a read-only search that is a minor omission.

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 sentences, no filler, and the scope statement precedes the usage rule so the reader gets identity first and behavior second. The enumeration is long but each item is a genuinely distinct resource type an agent may need to recognize in results.

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?

No output schema exists, yet the description covers the essential contract: what is searched, what counts as a match, and how to broaden to a full category listing. Return shape and default limit are handled by the schema, so the remaining gap is small.

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 100% so the baseline is 3, and the description earns above that by clarifying that query keywords are conjunctive and that an empty query combined with a category lists everything. It adds real semantics beyond the schema's terse 'Keywords, e.g. ...' phrasing.

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') plus an explicit inventory of the resource types covered (communities, scholarships, job boards, conferences, podcasts, newsletters, reports). This clearly separates it from siblings like search_members and list_resource_categories, which operate on different entities.

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?

States clear usage context ('Leave it empty to list everything in a category') and implies the category parameter should come from list_resource_categories. It does not explicitly say when to prefer this over search_members, but the domain scope is narrow enough that disambiguation is easy.

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