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

With no annotations, the description must carry the behavioral burden. It states that matching tools are returned with 'full structured metadata', but it does not disclose filter combination logic, default/max limits, or response shape. It is not misleading, but it adds only a general return statement.

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, front-loaded with the resource and search dimensions, followed by the return behavior. No filler or repetition; appropriately sized for the tool.

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 an 8-parameter search tool with no output schema and no annotations, the description is a bit thin: it does not explain what 'full structured metadata' includes, how multiple filters combine, or the default limit. The schema covers parameter semantics, so the tool is callable, but the description alone would leave an agent guessing about output and edge-case behavior.

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 the baseline is 3. The description's list of search dimensions (keyword, category, pricing, platform, tags, API availability, open-source) mirrors the schema parameters but adds no new semantic detail beyond what the schema already documents.

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 names a specific verb ('Search'), a concrete resource ('BroFindAI directory of 700+ AI tools'), and enumerates the filter dimensions. This clearly separates it from sibling tools like list_tags or get_tool_details, which are list/detail operations.

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?

No explicit when-to-use or alternative routing is given. The description implies a search use case but does not say when to prefer search_ai_tools over list_categories or get_tool_details, nor does it mention list_tags for vocabulary (that hint appears only in the schema).

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