Get Thing State

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

No annotations are provided, so the description carries full burden of behavioral disclosure. It simply restates the obvious 'get current state' without mentioning read-only nature, potential errors, or any side effects. It adds no information beyond the tool name.

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 short (one sentence), but it is under-specified rather than concise. It restates the tool's purpose without offering additional value, similar to a tautology. It is front-loaded but lacks substance.

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 tool with no annotations and a single parameter, the description provides no context about return format, error conditions, or relationship to other tools. Although an output schema exists, the description does not leverage it or add any contextual value. It is incomplete for an agent to fully understand behavior.

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 covers 100% of the single parameter (thing_id) with a description, so the baseline is 3. The tool description does not add any additional semantics or context about the parameter beyond what the schema already provides.

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 'Get the current state of a thing' clearly states the action (get) and the resource (state of a thing). It distinguishes from sibling tools like get_thing and update_thing_state by focusing specifically on retrieving the state. However, 'thing' is generic and could be more specific, but within context it is adequate.

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 guidance is provided on when to use this tool versus alternatives such as get_thing or get_chore_details. There are no examples of typical use cases or exclusions. The description alone does not help the agent decide between tools.

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