closeLtspiceWindow

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

Core behavior is stated (closes windows matching substring), but there is no mention of error handling, what happens if no windows match, or any side effects. With no annotations, the description carries the burden and is functional but minimal.

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?

Single sentence, no extra words. Front-loaded with action and key detail (substring matching). Exceeds conciseness requirements.

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 simplicity of the tool (1 parameter, no annotations, output schema present), the description covers the essential functionality. Could mention return behavior but not required.

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?

Description clarifies that title_hint is used for substring matching, adding meaning beyond the schema's type-only definition. Schema coverage is 0%, so the description compensates adequately.

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?

Description clearly states the action (close windows) and the matching criterion (title containing title_hint). It distinguishes itself from siblings like openLtspiceUi and setLtspiceUiEnabled.

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, no prerequisites, no exclusions. The description only states the function without contextual usage advice.

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