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

With no annotations provided, the description carries the full burden of behavioral disclosure. It indicates this is a destructive action ('Close') and adds useful context about user confirmation, but doesn't cover other important aspects like whether the closure is reversible, what happens to session data, or any permission requirements. This is adequate but has clear gaps for a mutation tool.

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 consists of two concise sentences that are front-loaded with the core functionality and followed by important usage guidance. Every word earns its place with no redundancy or unnecessary elaboration.

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 destructive operation with no annotations and no output schema, the description provides basic purpose and usage guidance but lacks details about behavioral consequences, return values, or error conditions. It's minimally viable but incomplete given the tool's complexity and potential impact.

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 input schema has 100% description coverage, with the single parameter 'session_id' fully documented in the schema. The description doesn't add any additional parameter information beyond what's already in the structured data, so it meets the baseline but doesn't provide extra value.

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 action ('Close') and target resource ('a specific session by session ID'), making the purpose immediately understandable. However, it doesn't differentiate this tool from potential sibling tools like 'reset_session' or 'cleanup_data' that might also manage sessions, so it doesn't reach the highest clarity level.

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 provides clear contextual guidance with 'Ask before closing if the user might still need it,' which helps determine when to use this tool. However, it doesn't explicitly mention alternatives like 'reset_session' or specify when NOT to use it, preventing a perfect score.

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