projector_show_dashboard

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

Annotations already declare destructiveHint=false and readOnlyHint=false, so the safety profile is covered. The description adds the useful facts that the URL is pre-configured and the display will be fullscreen, but it omits what happens if no dashboard is configured or which monitor is targeted.

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?

A single front-loaded sentence with no filler; every clause (open, configured dashboard URL, projector, fullscreen) carries information.

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 parameterless, non-destructive action with no output schema and annotations covering safety, this is nearly complete. Only the failure mode (no configured dashboard) and the return/confirmation behavior are left unspecified.

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?

Zero parameters, so the baseline is 4. The description still adds value by making clear the URL is configured rather than supplied, telling the agent not to look for a URL argument.

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?

States a specific verb (open), a specific resource (the configured dashboard URL), the target device (projector), and the mode (fullscreen). It implicitly distinguishes itself from projector_open_url by emphasizing the URL is pre-configured rather than passed in, though it never names that sibling.

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 when-to-use guidance and no mention of the nearest alternative, projector_open_url, nor any stated prerequisite such as a dashboard needing to be configured first. Usage is only inferable from the tool name.

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