Get a localized Google Play store listing

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

The annotations already establish a read-only, open-world operation, and the description adds the prerequisite that the app edit must already exist. It does not explain behavior for a missing edit or localization, edit-state constraints, or the returned representation; "Read" itself largely repeats readOnlyHint.

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 single sentence is front-loaded and contains no filler. It efficiently communicates the operation, cardinality, localization, and edit scope, although other dimensions require additional detail.

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?

The core operation is clear, but the absence of both parameter descriptions and an output schema leaves important invocation and result details undocumented. The definition omits how to acquire a valid editId, language-tag semantics, missing-listing behavior, and explicit selection guidance versus list_store_listings.

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?

With 0% schema description coverage, the description needed to compensate more for the three required parameters. It indirectly clarifies that language selects the localization and editId identifies an existing edit, but does not explain packageName, how to obtain an editId, or the language-tag convention beyond the schema's pattern.

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 uses a specific verb and identifies the resource and scope: reading one localized listing within an existing app edit. Its singular read scope distinguishes it from list_store_listings and patch_store_listing, while the title supplies the Google Play context.

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?

"One localized listing" and "existing app edit" imply that this tool is for a known language and an already-created edit. It does not explicitly direct agents to list_store_listings for multiple or unknown languages, or mention create_edit when no edit exists.

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