C2.7/5.0
Behavior2/5

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It does not state whether closing a session is destructive or reversible, whether it terminates the Radare2 process, whether unsaved state is lost, or what permissions are required.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single front-loaded sentence with no filler, so it is structurally efficient. However, its extreme brevity leaves required behavioral and parameter context unstated, keeping it from being fully appropriate.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a lifecycle mutation tool with no annotations and a single required parameter, the description omits side effects, reversibility, and session-state impact. An output schema exists so return values need not be explained, but the behavioral gaps remain significant.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and the required session_id parameter has no description. The description's only reference is the word 'session', which adds no format, constraints, or selection semantics beyond the parameter name already in the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('Close') and resource ('Radare2 session'), which clearly differentiates it from sibling lifecycle tools like create_session, list_sessions, and switch_session. It provides no additional scope or nuance, but the core purpose is unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Offers no guidance on when to use this tool versus alternatives such as switch_session or list_sessions, nor any prerequisites or conditions for closing a session. The intended usage is only implicitly inferable from the tool name.

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