List Installed Applications

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

No annotations provided, so description carries full burden. Description only says 'list', implying read-only, but doesn't confirm lack of side effects, rate limits, or required permissions. No mention of output format or error states.

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?

Description is one sentence (10 words), concise and front-loaded. It earns its place by stating the core purpose, but could be slightly more informative without sacrificing 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?

Given 1 required parameter, no annotations, and no output schema, the description is incomplete. It does not mention prerequisites, return format, or potential errors. For a tool that lists data, agents need to know what output to expect.

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 has 0% description coverage for parameter 'serial'. Description adds minimal value by implying serial identifies the device, but does not explain format, source (e.g., from list_devices), or that it is required.

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 verb 'list' and resource 'installed applications' with context 'on a specific Android device'. It effectively distinguishes from sibling tools like get_app_details (details of one app) and install_app/uninstall_app (modifications).

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 mentioned (e.g., device must be connected, serial from list_devices). The description only states the action without context.

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