deploy_app

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

No annotations are provided, so the description must fully disclose behavior. It states the deployment action and return details but does not mention side effects like version overwrites, required permissions, or failure conditions.

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 structured with Args and Returns sections, covering all parameters efficiently. While it is not overly verbose, it could be slightly more concise by removing redundant wording like 'Deploy an APK or AAB file to a Play Store track.'

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 tool's complexity (deployment with 6 parameters) and the presence of an output schema, the description adequately covers parameter semantics and return value. It lacks deeper behavioral details but is sufficient for most use cases.

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?

The input schema has 0% description coverage, but the tool description provides detailed explanations for all parameters, including acceptable values for track, defaults for rollout_percentage and language, and a hint about multilang release notes.

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 it deploys an APK or AAB file to a Play Store track. This distinguishes it from siblings like batch_deploy (which likely deploys multiple) and promote_release (which promotes existing releases).

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?

The description mentions an alternative for multilang release notes, implying when to use deploy_app_multilang. However, it does not provide explicit guidance on when to use this tool versus other siblings like batch_deploy or update_rollout.

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