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

No annotations are provided, so the description carries the full behavioral burden. It does not disclose whether code actually executes, what state is mutated, whether an existing session/context is required, or any side effects — for a 'debug update existing code' operation these are critical unknowns.

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?

It is a single short line with no wasted sentences, which is structurally fine, but the brevity comes from under-specification rather than economy of expression.

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 no annotations, no output schema, a meaningless parameter description, and three ambiguous siblings, the description is far too thin for an agent to invoke this tool correctly or route to it appropriately.

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 coverage is nominally 100%, but the single parameter 'detail' is described only as 'Specific parameters for this action,' which is a placeholder with no semantic content. The description adds nothing to clarify what 'detail' should contain or its format.

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 largely restates the tool name ('debug update existing code') and prefixes it with a vague role label ('Code interpreter (runner operator)'). It does not explain what debugging an update means operationally, nor does it distinguish this tool from siblings like generate_and_execute_code or generate_code_only.

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?

There is no statement of when to use this tool versus the three sibling tools, nor any prerequisites, exclusions, or context of use. The agent is left to infer everything from the name.

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