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 mentions the prerequisite but doesn't cover other important aspects like whether this requires authentication, if it's idempotent, what happens if charging is already active, or any rate limits. This leaves significant 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 is extremely concise (one short sentence) and front-loaded with the essential information. Every word earns its place, with no wasted text or redundancy.

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 that this is a mutation tool with no annotations but has an output schema (which handles return values), the description is minimally adequate. It covers the basic action and prerequisite but lacks details about behavioral traits, error conditions, or side effects that would be helpful for an 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?

Since there are 0 parameters and schema description coverage is 100%, the baseline is high. The description doesn't need to explain parameters, and it appropriately focuses on the action and prerequisite without unnecessary parameter details.

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 ('Start charging') and specifies a prerequisite ('vehicle must be plugged in'), which distinguishes it from other charging-related tools like tesla_charge_stop or tesla_set_charge_limit. However, it doesn't explicitly differentiate from all sibling tools beyond the charging context.

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 usage by stating the prerequisite condition ('vehicle must be plugged in'), which provides some context for when to use it. However, it doesn't explicitly mention when not to use it or name alternatives like tesla_charge_stop, leaving guidance incomplete.

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