upgrade_app

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

The description claims 'upgrade' which implies a mutating operation, but it does not disclose whether it is destructive, whether it preserves app data, or what happens if the app is already at the latest version. With no annotations, the burden is on the description, which falls short.

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?

The description is a single sentence, which is concise, but it omits critical details. It could be rephrased to include parameter guidance without becoming excessively long.

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 the presence of an output schema and a simple interface, the description should at minimum state what the output contains or any side effects. The lack of behavioral details and parameter guidance makes it incomplete for an agent to use reliably.

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 0%, and the description provides no explanation for the 'app_name' parameter, such as how to obtain valid values or what format to use. The agent is left to guess.

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 verb 'upgrade' and noun 'app' clearly indicate the action, and 'to the latest available version' specifies the target. However, it could be ambiguous whether 'latest available' refers to the app store or local cache, and it doesn't distinguish from siblings like 'update_app_config'.

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 is provided on when to use this tool versus alternatives like 'install_app' or 'update_app_config'. Prerequisites (e.g., app must be installed) are implied but not stated.

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