analysis_close

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

Annotations already declare destructiveHint=true and idempotentHint=true. The description adds 'release resources,' giving a bit more context about the side effect. However, it does not disclose consequences like the session becoming invalid or what happens if the session ID is unknown.

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 a single, concise sentence that immediately states the action and its purpose. No unnecessary words or information.

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?

The tool is simple with one parameter and an output schema, so the description need not explain return values. However, it omits crucial context such as the need to have an open session, how errors are handled, or the relationship to analysis_open. It is minimally adequate but lacks completeness for an agent encountering it cold.

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?

Schema description coverage is 0%, and the description does not mention the parameter at all. While the parameter name 'analysis_session_id' is self-explanatory, the description fails to compensate for the lack of schema documentation or provide guidance on how to obtain the session ID.

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 uses a specific verb ('Close') and resource ('analysis session'), clearly stating the tool's function. It also adds the effect 'release resources,' which distinguishes it from sibling tools like analysis_status or analysis_open.

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 the tool should be used when an analysis session is no longer needed, but it provides no explicit when-to-use or when-not-to-use guidance. It does not name alternatives or mention prerequisites like having an open session.

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