Execute Tool

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

The annotations already indicate this is not read-only, open-world, and not idempotent, but the description adds no extra behavioral context. It fails to disclose that the tool can invoke arbitrary tools with potentially side effects, what the return might be, or any risk/care advice.

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, front-loaded sentence with no fluff. Every word contributes to purpose and usage context, making it highly concise and well-structured.

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?

This is a meta-tool that dynamically executes other tools, yet the description only gives the bare minimum. There is no output schema, and the description does not mention return value, tool name lookup, or example usage. It leaves the agent without enough context to predict behavior.

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?

The schema already provides 100% descriptions for all parameters, so the baseline is 3. The description's phrase 'optional tool configs' slightly clarifies tool_configs, but it does not add any further parameter-level meaning.

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 executes a named tool directly with optional configs. It distinguishes itself from sibling chat/task tools by emphasizing 'without a full chat turn,' making the purpose very specific.

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?

It provides the clear context that this is for direct tool execution as opposed to a full chat turn. However, it does not explicitly name alternative tools or exclusions, so it just misses the top tier.

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