open_web_interface

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

With no annotations, the description carries the full burden of behavioral disclosure. It says 'open' but doesn't describe side effects, whether it starts a server, opens a browser, returns a URL, blocks execution, or requires permissions. This is as opaque as a tautology, providing no behavioral insight beyond the literal word.

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 only four words and lacks substantive content. While it is short, this is under-specification rather than concise efficiency. There is no structure to speak of, and the brevity fails to earn its place by omitting all useful detail.

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's role in opening a web interface, the description is severely incomplete. It doesn't mention how to access the interface (e.g., URL), what it displays, whether it runs asynchronous, or how to stop it. A complete description would need to cover at least these basics, and the lack of annotations or output schema makes this gap worse.

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 schema fully documents the single 'port' parameter with a default value, so high schema coverage leads to a baseline of 3. The description adds no parameter information, which is acceptable since the schema covers it completely.

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 'Open web visualization interface' gives a verb and a vague resource, but it doesn't specify what the visualization shows, how it is accessed, or what 'open' entails. It is nearly a restatement of the tool name and offers minimal differentiation from siblings, only differing by the word 'visualization'.

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 usage context is provided. The description gives no indication of when to use this tool versus alternatives, no prerequisites, and no mention of pairing with close_web_interface. It simply states an action without any situational guidance.

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