polynodes_navigation_random_trigger

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

The annotations already declare readOnlyHint=false, destructiveHint=false, idempotentHint=true, and openWorldHint=true, so the safety profile is covered. The description adds little beyond restating that it triggers changes and returns JSON confirmation, which is redundant given the output schema exists. It does not disclose what the mode change affects or any side effects.

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 front-loads the purpose. The Args/Returns docstring style is structured, though the 'Returns: JSON confirmation' line is unnecessary because an output schema already exists.

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, annotations, and output schema, the description is minimally adequate. However, it still leaves the agent without clear usage guidance and without an explanation of what 'random navigation mode changes' actually do, which limits confident invocation.

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 reported as 0%, so the description should carry more of the parameter burden. It only says 'params: state 1.0=on' and omits the off value, the nested object structure, and the meaning of the state parameter in context.

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 states a specific verb and resource: 'Trigger random navigation mode changes.' This is clear enough to distinguish it from most sibling parameter-setting tools, but it does not explain what 'random navigation mode' means or how it differs from related trigger tools like polynodes_rearrange_trigger.

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 explicit guidance on when to use this tool versus alternatives, no prerequisites, and no exclusions. The only usage-related detail is that 'params: state 1.0=on,' which is parameter information rather than contextual guidance.

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