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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It mentions it's a local utility, which implies no network calls, but does not detail permissions needed, rate limits, output format, or whether it's read-only or has side effects. For a tool with zero annotation coverage, this leaves significant gaps in understanding its behavior.

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 two sentences, front-loaded with the core purpose and followed by clarifying context. Every word earns its place without redundancy, making it efficient and easy to parse.

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?

Given the tool has no parameters, no annotations, and no output schema, the description is complete enough for a simple utility. However, it lacks details on output format (e.g., list structure, port types) and behavioral aspects like error handling, which could be useful for an AI agent to invoke it correctly in more complex scenarios.

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 tool has 0 parameters, with 100% schema description coverage, so no parameter documentation is needed. The description does not add parameter details, which is appropriate, and baseline is 4 for zero parameters as it avoids unnecessary information.

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 clearly states the specific action ('Get list of ports') and resource ('where Flutter/Dart processes are listening'), distinguishing it from sibling tools that focus on debugging, inspection, or other utilities. It explicitly notes this is a local utility rather than a Flutter RPC method, which helps differentiate it from network-related tools.

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?

The description provides clear context by specifying it's for local Flutter/Dart processes, implying usage when monitoring local development environments. However, it does not explicitly state when not to use it or name alternatives among the sibling tools, such as for network ports or other debugging purposes.

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