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

With no annotations provided, the description carries the full burden. It discloses key behavioral traits: the safety requirement (confirm=True) and the action's scope (unlocking all doors). However, it lacks details on permissions, rate limits, or error conditions, which would be helpful 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 front-loaded with the core purpose in the first sentence, followed by a concise parameter explanation. Every sentence earns its place by providing essential information without redundancy, making it highly efficient.

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 complexity (a mutation with safety constraints), no annotations, and an output schema (which handles return values), the description is mostly complete. It covers purpose, usage, and parameters well, but could improve by mentioning authentication needs or potential side effects.

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 schema description coverage is 0%, so the description must compensate. It fully explains the single parameter 'confirm', including its purpose ('Must be True to execute'), safety role, and default behavior ('Prevents accidental unlocks'), adding significant meaning beyond the bare schema.

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 ('Unlock all doors') and specifies the resource (Tesla vehicle doors). It distinguishes itself from sibling tools like 'tesla_lock' by performing the opposite action, making the purpose specific and unambiguous.

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 explicitly states when to use this tool ('Requires confirm=True for safety') and provides a clear exclusion ('Prevents accidental unlocks'). It differentiates from alternatives by focusing on unlocking all doors, unlike other tools for climate control or charging.

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