calls_create

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

With no annotations provided, the description carries full burden for behavioral disclosure. 'Create a new call record' implies a write/mutation operation but provides no information about permissions required, whether the operation is idempotent, what happens on failure, rate limits, or what the response contains. This leaves significant behavioral questions unanswered for a mutation 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 is extremely concise at just 5 words, with zero wasted language. It's front-loaded with the core action and resource. While this conciseness comes at the cost of completeness, the structure itself is optimal for what little information is provided.

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 mutation tool with complex nested parameters (2 parameters with deep nesting), 0% schema description coverage, no annotations, and no output schema, the description is severely inadequate. It doesn't explain the parameter structure, required fields, behavioral constraints, or what to expect upon success/failure, leaving the agent with insufficient context to use this tool effectively.

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?

With 0% schema description coverage and 2 parameters (one required), the description provides no information about parameters. The schema shows complex nested objects with many properties, but the description doesn't explain what 'properties' or 'associations' mean in this context, nor does it mention required fields like 'hs_call_body' and 'hs_call_title'.

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' clearly states the verb ('Create') and resource ('call record'), making the basic purpose understandable. However, it doesn't differentiate this tool from sibling tools like 'calls_batch_create' or other create tools in the system, leaving ambiguity about when to use this specific single-create versus batch alternatives.

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. With sibling tools like 'calls_batch_create' available, there's no indication whether this is for single-record creation versus batch operations, nor any prerequisites or context for when this specific tool is appropriate.

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