calls_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 mentions 'update' which implies mutation, but doesn't disclose behavioral traits like whether it's idempotent, what permissions are required, if there are rate limits, how errors are handled in batch operations, or what the response format looks like. 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?

The description is a single, efficient sentence with zero wasted words. It's front-loaded with the core action and resource, making it immediately understandable. Every word earns its place.

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 (a complex nested array), 0% schema description coverage, no annotations, and no output schema, the description is insufficient. It doesn't explain the parameter structure, behavioral implications, error handling, or response format. The agent would struggle to use this tool correctly without additional context.

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 for undocumented parameters. The description mentions 'multiple call records' which hints at the 'inputs' array parameter, but doesn't explain the structure of individual records (id + properties), the required fields, or the meaning of properties like 'hs_call_direction' or 'hs_call_status'. It 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 call records') with the operational context ('in a single request'). It distinguishes from the singular 'calls_update' tool by specifying batch operations, though it doesn't explicitly contrast with other batch tools like 'calls_batch_create' or 'calls_batch_read'.

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 versus alternatives. It doesn't mention prerequisites like authentication, compare it to the singular 'calls_update' for single-record updates, or explain when batch updates are preferable over individual updates. The description only states what it does, not when to use it.

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