subscription_base_plans_batch_update

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

With no annotations and only 'upsert' mentioned, the description fails to disclose critical behavioral traits such as idempotency, error handling, permission requirements, or whether updates are partial or full. The mutation nature is implied but not elaborated.

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, efficient sentence with no fluff. However, given the tool's complexity, it could benefit from additional structured context without harming conciseness.

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 batch mutation tool in Google Play subscriptions, the description lacks details on return values, required fields beyond those in the schema, and how the tool interacts with related resources. No output schema is provided, and the requests parameter is left ambiguous.

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 input schema has 67% description coverage (packageName and productId are described). The description adds 'up to 100' context for the batch size but does not explain the 'requests' field, which is a key parameter with an unspecified structure.

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 specifies the verb 'upsert' and resource 'base plans' with a batch limit of 100, indicating a create-or-update operation. However, it does not differentiate from sibling tools like subscription_base_plans_batch_update_states, which target different aspects of the same resource.

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 is provided on when to use this tool vs alternatives. There is no mention of prerequisites, context, or exclusions, leaving the agent to infer usage from the name alone.

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