launch_ui_tool

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It only says 'Launch the web visualization UI' without mentioning side effects like port binding, browser opening, or any state changes. The parameters imply behavior but are not discussed.

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 a single sentence, which is front-loaded but overly sparse. It is too minimal to be considered well-structured; it prioritizes brevity over completeness. A 3 reflects adequacy but with clear gaps.

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 two parameters, no output schema, and no annotations, the description is incomplete. It fails to convey return behavior, parameter usage, or any operational context. The minimal description leaves the agent underinformed.

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 0%, and the description adds no meaning beyond the schema's parameter names and defaults. It does not explain what 'port' or 'open_browser' control, leaving the agent to infer from their titles and defaults alone.

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 it launches a web visualization UI for graph exploration. The verb 'launch' is specific, and the resource 'web visualization UI' is distinct from sibling tools that deal with PII patterns, caching, or graph analysis.

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 guidance on when to use this tool versus alternatives. The description lacks any context on prerequisites, scenarios, or exclusions. Given the lack of context signals (e.g., no annotations), the agent receives no help in deciding when to invoke this tool.

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