Update Call

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

The description aligns with annotations (readOnlyHint=false, idempotentHint=true) by indicating an update operation. However, it lacks details on required permissions, error handling, or side effects beyond stating the fields updated.

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 brief, single sentence, front-loading the key action. While concise, it could expand slightly to cover more parameter interactions without significant bloat.

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?

With five parameters including a boolean qualification and an enum state, the description does not explain how these fields relate or interact. No return value is described, and the tool could benefit from additional context on usage patterns.

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%, so the input schema already defines each parameter. The description adds no further parameter-level meaning beyond the high-level purpose, which is adequate.

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 tool updates the qualification status or state of existing call records, which distinguishes it from create/delete siblings. However, it does not mention the ability to update other fields like name or externalIds, limiting full scope clarity.

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 implies usage for updating existing call records but provides no explicit guidance on when to use this tool versus alternatives (e.g., create_call, delete_call). No when-not or prerequisite information is given.

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