reply_to_google_play_review

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

Discloses that replies are limited to 350 characters and that existing replies are replaced. Annotations indicate not read-only and not destructive, which aligns.

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 sentences, front-loaded with the action, concise and includes practical tips without redundancy.

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?

Covers all necessary aspects: purpose, parameter sources, constraints, and best practices. No output schema needed for this simple mutation.

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?

All parameters already have schema descriptions (100% coverage). The description adds value by indicating the source of review_id and reinforcing the character limit.

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?

Clearly states 'Post or update a developer reply to a Google Play user review', specifying the verb and resource. Distinguishes from sibling tools like list_google_play_reviews and other mutation tools.

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?

Advises to get review_id from list_google_play_reviews and provides guidance on writing helpful replies. Could be more explicit about when not to use, but context is clear.

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