close_session

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

The description discloses the destructive action of killing the Chrome process, which is important. However, with no annotations provided, it lacks further behavioral context such as idempotency, whether it can be called multiple times, or side effects on other sessions.

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?

Description is a single, concise sentence with no extraneous information. Every word adds value, clearly stating the action and the key behavioral consequence.

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 tool's simplicity (no parameters, no output schema), the description is mostly complete. It explains the purpose and the main effect. However, it could mention if there is any return value or success indication, but that is minor.

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?

Tool has no parameters (0 params, schema coverage 100%). According to the guideline, baseline for 0 params is 4. The description adds no parameter info, but that is acceptable since none exist.

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?

Description clearly states the action (close browser context) and the specific effect (kills Chrome process). Verb 'close' and resource 'browser context' are specific, and the tool name aligns. No sibling tools have similar functionality.

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?

No explicit guidance on when to use this tool or alternatives. Since there are no sibling tools for session management, it is implied for cleanup after automation, but the description does not state prerequisites or typical workflow placement.

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