emails_batch_update

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

No annotations are provided, so the description carries full burden. It states it's an update operation but doesn't disclose behavioral traits like required permissions, whether it's idempotent, rate limits, error handling for partial failures, or what happens to unspecified properties. This is inadequate for a mutation tool with zero annotation coverage.

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?

Single sentence, front-loaded with the core action, zero waste. Every word earns its place by conveying the batch update nature efficiently.

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 with 1 parameter (complex nested array), 0% schema description coverage, no annotations, and no output schema, the description is incomplete. It lacks details on input structure, behavioral expectations, error handling, and output format, leaving significant gaps for an AI agent.

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 0%, so the description must compensate. It mentions 'multiple email records' which hints at the 'inputs' array parameter, but doesn't explain the structure (id + properties), required fields, or the meaning of properties like hs_email_status enums. The description adds minimal value beyond the schema.

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 resource ('multiple email records'), and specifies it's a batch operation ('in a single request'). It distinguishes from non-batch tools but doesn't explicitly differentiate from other email batch operations like emails_batch_create or emails_batch_archive among the siblings.

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 on when to use this tool versus alternatives like emails_update (single update) or emails_batch_create (batch creation). The description implies batch updating but doesn't specify prerequisites, constraints, or when-not-to-use scenarios.

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