Open Schematic In Gui

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

Annotations already declare readOnly=false, openWorld=true, non-idempotent, non-destructive. The description adds that this launches in GUI rather than batch mode ('without -b'), which is useful context. It does not disclose whether a desktop/GUI environment is required, how sessions are tracked, or how this interacts with the live-GUI session tools that clearly exist among the siblings.

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 short, front-loaded sentence with no filler. It is efficient, though arguably terse enough that clarity is traded away for brevity.

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 stateful, open-world GUI-launch tool with no output schema and an undocumented required parameter, the description is thin. It should explain session lifecycle behavior and the required argument, especially given the surrounding live-GUI session family.

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 coverage is only 50%; the required schematic_path parameter has no schema description, and the description says nothing about path format, absolute vs relative, or how it relates to workspace_root. The description does not compensate for the coverage gap.

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 (Launch) and resource (LTspice on a schematic), and the '-b' qualifier distinguishes it from batch-mode simulation tools. However, it does not explicitly name the sibling it differs from (refresh_schematic_in_gui, close_live_gui_session), leaving differentiation partly inferential.

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 when-to-use guidance, no prerequisites, and no mention of alternatives such as refresh_schematic_in_gui or close_live_gui_session. The agent must guess whether this starts a new session or reopens an existing one.

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