get_lock_status

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

With no annotations, the description carries the disclosure burden. It indicates a read-only retrieve operation by the word 'Get' and lists the data returned, but it does not explicitly state side-effect-free behavior, failure/error behavior for a bad device_id, or whether status is live vs cached.

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 short sentences contain only useful information: what the tool returns and the required prerequisite. The action and scope are front-loaded.

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 single-parameter read tool with no output schema, the description covers what will be returned and how to get the parameter. It omits edge-case behavior, but the essential calling context is present.

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 coverage is 100%, giving baseline 3. The description adds value beyond the schema by telling the agent where to obtain device_id and that it must be obtained first from list_locks.

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 starts with a specific verb ('Get'), names the exact resource ('current status ... for one lock'), and enumerates the returned fields (status, battery level, model/serial). This clearly differentiates it from sibling tools like list_locks (listing) and lock_door/unlock_door (actuation).

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 gives a clear prerequisite and data source: 'Get device_id from list_locks first.' It does not explicitly say when not to use this tool, but the operation is unique among the siblings, so the workflow instruction is the main needed guidance.

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