Uninstall App

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

DestructiveHint annotation already indicates destructive behavior. Description adds no additional behavioral details beyond stating the action. No mention of side effects or data removal.

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, clear sentence with no unnecessary words.

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 simple destructive tool with no output schema, the description is sufficient to understand the core action. Could mention return value or confirmation, but not essential.

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 description coverage is 100%; description adds no extra meaning beyond what is in the schema. The schema already describes device and packageName well.

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?

The description clearly states the verb 'Uninstall', the resource 'app', and the method 'by package name'. It is distinct from sibling tools like android_install_app or android_terminate_app.

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 vs alternatives, such as android_terminate_app for stopping without removing, or prerequisites like requiring the app to be installed.

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