upload_android

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

With no annotations, the description carries the full behavioral burden but only states the destination and track options. It does not disclose authentication or permission requirements, overwrite or version-conflict behavior, whether custom tracks must already exist, or likely failure modes.

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 front-loaded sentence that states the action, artifact, destination, and valid track choices without waste. Every phrase contributes useful selection or invocation context.

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 an upload mutation with no annotations and 0% schema description coverage, the description is too thin operationally. It covers purpose and track selection, but omits permissions, conflict handling, and other prerequisites an agent needs to invoke it safely; the output schema does not need explanation, but invocation context is incomplete.

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%, so the description must compensate for all parameter meaning. It usefully clarifies the track values (internal, alpha, beta, custom closed track name) and implies aab_path refers to an .aab file, but it does not explain package_name format or path constraints for the two required parameters.

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 names a specific action (upload), artifact (.aab), and destination (Google Play test track), and enumerates track types. The Android-specific scope and test-track focus clearly distinguish it from upload_ios and from promotion/rollout siblings.

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 context implies use for uploading Android app bundles to a test track, but there is no explicit guidance on when to use this versus promote_android or update_rollout_android, nor when not to use it such as for production. The valid tracks are listed, but alternatives and exclusions are left to inference.

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