playstore_update_listing

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

Discloses immediate commitment of changes, which is useful. No annotations provided, so the description carries the burden. However, it does not mention authentication needs, rate limits, or whether it overwrites existing data. Character limits are good but not sufficient.

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 succinct sentences with no filler. Every piece of information is relevant and front-loaded.

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 a simple update tool with no output schema, the description covers the key aspects: purpose, fields, limits, and immediacy. However, it could mention response behavior or error conditions.

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 coverage is 100% and includes character limits for each parameter. The description adds 'Changes are committed immediately' but otherwise repeats schema info. Minimal added value beyond 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 it updates store listing metadata (title, short description, full description) for a specific language, with character limits. This distinguishes it from sibling tools like playstore_get_listing (read) and playstore_delete_images (delete).

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 on when to use this tool vs alternatives, no prerequisites, no mention of required setup (e.g., signed APK). The description lacks context for proper selection.

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