Maximize app window

maximize_app

Maximize any app's window and bring it to front. Specify the app name or use a PID to choose among multiple open windows.

Instructions

Maximize an app's window and bring it to front.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
appYesFriendly app name or process name
pidNoProcess ID to pick a specific window when more than one window of this app is open. Omit it first - if there are multiple matches, the tool lists their PIDs and titles so you can retry with the right one.
Behavior2/5

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

With no annotations provided, the description carries the full behavioral burden, but it only states the main effect and does not disclose side effects, multi-window behavior, or failure modes. The only extra behavioral detail, listing PIDs and titles on ambiguous matches, lives in the pid parameter schema rather than the description.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single ten-word sentence with no filler or repetition. It front-loads the primary action ('Maximize') and adds the secondary behavior ('bring it to front') efficiently.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is simple and its two parameters are fully documented, but the description omits return behavior, error conditions, and guidance on when to prefer this over similar window tools. Since there is no output schema and no annotations, some of this information is missing entirely.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, and both parameters already have meaningful descriptions, especially pid with its multi-match retry guidance. The tool description adds no parameter-level meaning beyond what the schema already provides, so the baseline score of 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Maximize') and resource ('an app's window') and adds 'bring it to front,' which clearly distinguishes it from siblings like minimize_app and focus_app. An agent can tell what this tool does without inspecting the schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use the tool by stating its action, but it provides no explicit when-to-use or when-not-to-use guidance and names no alternatives such as focus_app or minimize_app. The intended context must be inferred rather than stated.

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