nexo_lifecycle_stop_nexo_session

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

The description includes 'best-effort' and 'explicit', hinting at non-guaranteed behavior and active stopping. However, with no annotations, it fails to disclose side effects, idempotency, required permissions, or return values. The burden is not fully met.

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 sentence, which is concise. However, it uses jargon like 'nexo_stop' and 'SID' without explanation, and the structure could front-load the core action more effectively.

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 simple tool with one parameter and no output schema or annotations, the description is incomplete. It does not explain return values, error conditions, or what 'cleanup' entails, leaving gaps for the agent.

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 description confirms that the 'sid' parameter is the session ID, which adds some meaning beyond the schema. However, with 0% schema description coverage, it should provide more detail about the format or source of the SID.

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 verb 'stop' and identifies the resource as a NeXO session via SID. It adds context 'for Desktop lifecycle cleanup', which helps distinguish from general stop tools. However, the phrasing 'nexo_stop' is jargon and could be clearer.

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 vaguely mentions 'Desktop lifecycle cleanup' but provides no explicit guidance on when to use this tool versus alternatives like nexo_stop or nexo_lifecycle_wait_for_stop. No when-not-to-use or prerequisite information is given.

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