get_gui_url

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

No annotations are provided, so the description carries the full burden. It discloses that the tool returns an HTTP URL, which is useful behavioral context. However, it lacks details on potential errors, authentication needs, or rate limits, leaving gaps for a tool that likely involves network access.

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 with zero waste: it front-loads the core purpose and adds clarifying detail about the return value. Every sentence earns its place by providing essential information without fluff.

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 simplicity (0 parameters, no output schema), the description is adequate but has gaps. It explains the return value but lacks context on error handling or integration with sibling tools. For a tool that likely fetches a URL, more behavioral details would enhance completeness.

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 zero parameters, and the schema description coverage is 100% (as there are no parameters to cover). The description does not need to add parameter semantics, so a baseline of 4 is appropriate, as it efficiently avoids redundancy.

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') and resource ('GUI dashboard URL'), and distinguishes its purpose by specifying it returns 'the HTTP URL where the live event viewer is accessible.' This is precise and unambiguous, avoiding tautology with the tool name.

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 no guidance on when to use this tool versus alternatives (e.g., sibling tools like 'claude' or 'codex'), nor does it mention any prerequisites or exclusions. It only states what the tool does, leaving usage context implied at best.

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