chitchats_add_to_batch

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

With no annotations provided, the description bears full responsibility for disclosing behavioral traits. It only says 'add', implying a mutation, but it does not disclose side effects, whether shipments are removed from other batches, idempotency, validation rules, or potential failure modes. The description offers no information about the effects of the operation beyond the basic verb.

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, concise sentence with no unnecessary words. It is front-loaded with the verb and clear object structure, making it easy to parse quickly. Every word contributes to the meaning 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?

The tool has no output schema and no annotations, so the description must compensate. It does not explain what happens after adding (e.g., return value, batch state changes), nor does it provide context about batch lifecycle or constraints (e.g., whether shipments must be in a certain status). The brief description is insufficient for an agent to fully understand the operation's implications.

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 description coverage is 100%, with both batch_id and shipment_ids having clear descriptions. The tool description adds little beyond the schema: 'one or more shipments' merely paraphrases the array parameter. Since the schema already documents the parameters, the description provides no additional semantic value, so the baseline of 3 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 action ('Add') and the resource ('shipments to a batch'), with the scope of 'one or more' explicitly mentioned. This is a specific verb+resource statement that naturally distinguishes from sibling tools like remove_from_batch and create_batch.

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 provides no guidance on when to use this tool versus alternatives. It does not mention situations where this tool is appropriate, prerequisites, or contrast with related operations like chitchats_remove_from_batch or chitchats_create_batch. Any usage context is only implied by the verb 'add'.

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