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

With no annotations provided, the description carries full burden. It discloses the action ('Send quit command') and outcome ('terminate the REPL session'), but doesn't mention behavioral aspects like whether this requires specific permissions, if termination is immediate or graceful, or what happens to unsaved state. It adds basic context but lacks richer behavioral details.

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 perfectly concise with two sentences: the first states the action and purpose, the second describes the return value. Every word earns its place with zero redundancy, and key information is front-loaded.

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?

For a 0-parameter tool with no annotations and no output schema, the description provides adequate context about what the tool does and what it returns. However, it could be more complete by explaining what 'The result of the quit command' entails (e.g., success confirmation, error message, or session status).

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 tool has 0 parameters with 100% schema description coverage, so the baseline is 4. The description doesn't need to explain parameters, and it correctly doesn't mention any. No additional parameter semantics are required or provided.

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 specific action ('Send quit command') and target resource ('to NeoConsole') with the explicit purpose 'to terminate the REPL session'. It distinguishes from siblings like 'shutdown_repl_session' by specifying it's a command sent to NeoConsole rather than a direct session shutdown.

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?

The description implies usage context ('to terminate the REPL session') but doesn't explicitly state when to use this versus the sibling 'shutdown_repl_session' tool. It provides clear functional context but lacks explicit comparison or exclusion guidance for alternatives.

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