v1.0.3Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure, and it discloses nothing. It does not say whether the operation is idempotent, what happens if the window is already maximized, whether it errors on a disconnected session, or how it interacts with other window-state tools.
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 waste, but the brevity reflects under-specification rather than efficiency. It earns its place only as a restatement of the name.
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?
With no annotations, no output schema, and an undocumented required parameter, the definition leaves the agent guessing about error behavior and preconditions for a state-mutating window operation. For a tool this simple a couple of extra clauses would have made it complete.
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?
There is one required sessionId parameter with 0% schema description coverage, and the description adds no meaning about which session it refers to or whether the session must be live. The parameter is inferable from its name but is entirely undocumented in both the schema and the description.
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 and resource ('Maximize Electron main window'), and the target being the Electron main window distinguishes it from viewport/browser-window operations. However, it is essentially a restatement of the tool name and does nothing to differentiate it from the closely related focus_main_window, minimize_main_window, and get_main_window_info siblings.
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 maximize versus focus, minimize, or restore, and no mention of prerequisites such as the session needing to be connected and active. The agent must infer usage purely from the name.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
