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

With no annotations, the description must reveal behavioral traits but only lists topics. 'Installs' could imply a mutating action, yet there is no clarification of read-only vs. side effects, auth requirements, or rate limits. The ambiguity is a serious transparency gap.

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?

The description is very short and compact, but the brevity sacrifices meaningful content. It is under-specified rather than efficiently concise, offering only a fragment that does not earn its place as a useful definition.

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 tool with one undocumented parameter and no annotations, the description is far too incomplete. An agent cannot reliably know how to construct a query or what to expect in response, even with an output schema present.

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?

The single parameter 'q' has zero schema description coverage and is not mentioned in the tool description. The description does not explain what query syntax, format, or expected input is needed, leaving the parameter entirely undocumented.

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 identifies Homebrew as the resource and mentions formula/cask version, dependencies, and installs. However, it is a noun phrase without a clear verb, and it does not explicitly state whether the tool searches, retrieves, or installs. It gives a general sense but leaves the core action ambiguous.

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?

There is no guidance on when to use this tool or how it differs from the many sibling tools. No alternatives or exclusions are mentioned, so the description provides no contextual direction for an agent deciding between tools.

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