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

No annotations are provided, and the description does not disclose any behavioral traits such as return format, scope (direct vs. transitive callees), prerequisites, or side effects. The description is a tautology that adds no new information beyond the tool name.

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 short (4 words) but lacks structure and substance. It is underspecified rather than appropriately concise. Every sentence should earn its place, and this one fails to provide any meaningful guidance.

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 the complexity of the tool (binary analysis, many sibling tools, no output schema, two required parameters), the description is completely inadequate. It does not explain the output, the parameters, or how this tool relates to the many similar tools in the sibling list.

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 has 0% description coverage for the two parameters ('session_id' and 'function_start'). The description does not explain what these parameters represent or how they should be used. The agent receives no help understanding the input beyond the parameter names.

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 'Callees of a function' vaguely indicates the tool returns the functions called by a given function. However, it uses a noun phrase instead of a verb+resource, and it does not distinguish the tool from the sibling 'function.callers' which is the inverse operation. The purpose is clear only if the agent infers the action from the name.

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 guidance on when to use this tool versus alternatives like 'function.callers' or other analysis tools. The description provides no context for selection, leaving the agent to guess based on the tool name alone.

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