playstore_status

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

With no annotations, the description carries the full burden. It accurately describes the tool as performing a read-only check that displays service account details and validates a key file. No hidden side effects or destructive actions are indicated, though it could explicitly state it does not modify anything.

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 sentence that front-loads the main action ('Check Google Play Store API configuration status') and adds two specific details. It is maximally concise with no wasted words.

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 zero-parameter, read-only status check tool, the description covers the core functionality: verifying configuration, displaying service account details, and validating the key. It is sufficiently complete given the tool's simplicity, though a note about expected output or error handling would enhance it.

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?

The tool has no parameters, and schema description coverage is 100% (zero parameters). The description does not need to add param information since none exist. Baseline of 4 is appropriate.

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 checks Google Play Store API configuration status, showing service account details and validating the JSON key file. This distinguishes it from sibling status tools like admob_status or get_status by specifying the resource (Play Store API) and specific actions (shows, validates).

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 description implies usage for verifying Play Store API setup, but it lacks explicit guidance on when to use versus alternatives like admob_status or get_status. No exclusions or prerequisites are mentioned, leaving the agent to infer context.

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