batch_update_subscription_offers

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

No annotations are provided, so the description must carry the behavioral disclosure burden. It does disclose that the tool is disabled in read-only mode, which is useful. However, it does not describe other behavioral aspects like atomicity, partial failure handling, or idempotency, which are relevant for a batch update tool.

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 consists of two concise sentences that effectively front-load the purpose and include a critical usage note. There is no verbosity or redundant information, making it highly efficient.

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?

The tool has a clear output schema (not shown) and complete parameter documentation, so the description does not need to explain return values. The description covers the core purpose and the read-only restriction, which is sufficient for a batch update operation. It could add a note about usage as a batch alternative, but overall it is fairly complete.

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 100% coverage of all four parameters, and the description adds no additional parameter-level detail beyond the schema. According to the rubric, with high schema coverage, the baseline score is 3, and there is no extra contribution from the description.

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 action 'update' and the resource 'subscription offers', with the scope 'multiple' and 'in a single operation'. This distinguishes it from sibling tools like patch_subscription_offer (single update) and batch_update_subscription_offer_states (which updates states, not offers).

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 mentions 'Disabled in read-only mode', which gives a usage constraint, but does not explicitly compare to alternatives such as batch_update_subscription_offer_states or patch_subscription_offer. It lacks guidance on when to choose this batch operation over iterating single updates.

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