call_tool

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

No annotations are provided, so the description carries full burden for behavioral disclosure. 'Handle tool calls' reveals almost nothing about the tool's behavior - it doesn't indicate whether this executes tools, validates calls, routes requests, or performs other operations. It provides no information about permissions, side effects, error handling, or response characteristics.

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 maximally concise at just three words. There's no wasted language or unnecessary elaboration. While this conciseness comes at the expense of clarity, the description itself is efficiently structured with zero redundancy.

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 that this appears to be a core tool invocation mechanism with 2 required parameters, nested objects in the schema, and an output schema, the description is completely inadequate. 'Handle tool calls' doesn't explain what the tool does, how to use it, what it returns, or how it relates to the sibling 'list_tools' tool. The presence of an output schema helps, but the description provides insufficient context for effective use.

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 the completely undocumented parameters. The description provides no information about what 'name' and 'arguments' represent, their expected formats, or how they should be used. With 2 required parameters that have no schema documentation, this represents a significant 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 'Handle tool calls' is tautological - it essentially restates the tool name 'call_tool' without adding meaningful specificity. It doesn't clarify what 'handle' means in this context (invoke? execute? manage?) or what types of tools are being called. While it distinguishes from 'list_tools' by implying action rather than listing, the purpose remains vague.

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 about when to use this tool versus alternatives. The description doesn't indicate whether this is for invoking specific tools, executing tool workflows, or managing tool calls. With a sibling tool 'list_tools' available, there's no indication of the relationship between listing tools and calling them.

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