disable_guest_mode

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

With no annotations, the description carries the full burden of behavioral disclosure. It usefully adds the 'auto-wakes if asleep' caveat, which is a meaningful behavior beyond the core action. However, it does not mention permissions, reversibility, response behavior, or what happens if guest mode is already disabled, leaving notable gaps.

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, front-loaded sentence that states the action first and adds a relevant behavioral note. Every word earns its place, with no redundancy or fluff.

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 schema covers all parameters and the description adds a useful wake-behavior detail, but with no annotations or output schema, the description still lacks usage context, async/command-completion semantics, and failure behavior. It is minimally adequate but not complete.

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 100% for all three parameters (vin, max_attempts, wait_for_completion), so the baseline is 3. The description adds no parameter-specific guidance, but the schema already documents each parameter adequately.

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 the specific verb 'Disables' and names the exact resource 'Guest Mode', making the purpose immediately clear. The 'auto-wakes if asleep' clause adds a distinguishing behavioral detail, and the resource name differentiates it from sibling tools like disable_valet_mode or enable_guest_mode.

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 is provided on when to use this tool versus alternatives such as enable_guest_mode or disable_valet_mode. The intended use is only implied by the tool's name and description, with no conditions, prerequisites, or exclusions stated.

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