as_aab_build_apks

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

Annotations provide basic hints; description adds bundletool context and return type. Does not disclose side effects like file overwriting or download requirements (confirm param hints but not elaborated).

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?

Two concise sentences plus a bullet list and return type. Front-loaded and no extraneous info.

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?

Adequate for a simple conversion tool with good schema coverage, but lacks behavioral details like output format structure or prerequisites beyond what schema indicates.

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 descriptions already cover parameters well (high schema coverage). Description only lists parameter names, adding minimal value beyond the schema.

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 tool converts an .aab to .apks, naming the underlying tool (bundletool). It distinguishes from siblings like as_aab_install.

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 explicit when-to-use or alternatives. Implied usage but lacks context like prerequisites (e.g., having an .aab file) or exclusions.

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