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

Annotations only indicate non-readOnly and non-destructive. The description adds critical behavioral context: 'Takes effect immediately — there is no staging step and no GET endpoint to retrieve current labels.' This reveals the immediate and irreversible nature beyond what annotations provide.

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 compact paragraph of five sentences, each adding essential information. It front-loads the main action and efficiently covers input source, usage scenarios, and behavioral implications 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?

Given the tool has two well-described parameters, no output schema, and sibling tools, the description covers the key aspects: purpose, input format, when to use, and side effects. It does not explain the response or error handling, but the immediate effect note compensates.

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% with detailed descriptions for both parameters. The description adds value by explaining the source of the CSV ('exported from Play Console → App content → Data safety → Export CSV'), which supplements the schema's technical details.

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 verb 'Submit' and the resource 'data safety declaration for a Google Play app', with additional context on what the declaration describes. It distinguishes from sibling tools that handle store listings, uploads, or other Google Play operations, though no explicit comparison is made.

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 specifies when to use the tool: 'Re-upload whenever data practices change' and accepts CSV from a specific Play Console export path. It implies when not to use it (if no GET endpoint exists, avoid retrieval), but does not explicitly mention alternatives or exclusion scenarios.

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