calls_create

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 'create' implies a write operation but doesn't disclose any behavioral traits: no information on permissions required, whether it's idempotent, rate limits, error handling, or what happens on success/failure. For a mutation tool with zero annotation coverage, this is a significant gap.

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 wasted words. It's appropriately sized for a basic tool, though this conciseness comes at the cost of completeness. Every word earns its place by stating the core action.

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?

Given the complexity (2 parameters with nested objects, no output schema, no annotations), the description is severely incomplete. It doesn't explain what a 'call record' entails, how to structure inputs, what the tool returns, or any behavioral context. For a creation tool in a rich CRM environment with many siblings, this minimal description is inadequate.

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%, meaning no parameters are documented in the schema. The description adds no parameter information beyond the tool name—it doesn't explain the 'properties' and 'associations' parameters, their structure, or required fields like 'hs_call_body' and 'hs_call_title'. With 2 parameters and nested objects, the description fails to compensate for the schema gap.

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 'Create a new call record' restates the tool name 'calls_create' with minimal elaboration. It specifies the verb 'create' and resource 'call record', but doesn't distinguish it from sibling tools like 'calls_batch_create' or other create operations (e.g., 'meetings_create', 'notes_create'). This is borderline tautological rather than providing meaningful differentiation.

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 doesn't mention sibling tools like 'calls_batch_create' for bulk operations, 'calls_update' for modifications, or other creation tools for different entities. There's no context about prerequisites, constraints, or typical use cases.

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