Tesla Status

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

No annotations are provided, so the description carries the burden. It discloses the returned field categories and that it is a 'latest position snapshot', which is useful, but says nothing about freshness/staleness, auth requirements, or whether the data is cached versus live. It adds moderate context beyond a bare purpose statement.

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?

Two tightly written sentences that front-load the resource and its fields. No filler; the only mild redundancy is the second sentence restating content already implied by the first.

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 low-complexity, single-optional-parameter read tool with an output schema present, the description explains what is returned without needing to detail return values. The key gap is the lack of differentiation from tesla_live/tesla_state_history, which matters in this crowded toolset.

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?

Only one optional parameter (car_id) exists and schema description coverage is 100%, so the schema already documents the ID filter and its default behavior. The description adds no meaning beyond that, which is acceptable baseline given full schema coverage.

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?

States a specific resource set ('Current vehicle state') and enumerates the fields returned (battery, range, location, climate, odometer), plus the source (TeslaMate). However, it does not differentiate from likely-overlapping siblings such as tesla_live or tesla_state_history, so the agent cannot fully disambiguate from the text alone.

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 when-to-use, when-not-to-use, or alternative guidance is given. With ~37 sibling tools including tesla_live and several history/status tools, the absence of routing guidance leaves the agent to guess which 'current state' tool to call.

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