smarthome_chat

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

The description adds useful context about routing through the platform's domain-agent dispatcher and scoping under JWT/tenant/company, which is not in the annotations. However, it does not explain the side effects or consequences of the chat action, which is significant given destructiveHint=true and idempotentHint=false.

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 tight and front-loaded: the first sentence states the action, the second provides scope/routing, and the arg list is minimal. Every sentence earns its place, with no filler or redundant repetition of the schema.

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?

Core invocation details are present: what action runs, routing scope, and both parameters. However, the description lacks examples, guidance on what the 'chat' action actually does, and any warning about destructive side effects despite the destructiveHint. The output schema mitigates return-value concerns, but the tool still feels underspecified for safe autonomous use.

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 0%, so the description carries the burden of explaining parameters. It does add meaning: message is a free-text objective, and inputs is an optional JSON string of structured inputs. This is more informative than the bare schema, though 'structured inputs' remains somewhat vague.

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 verb and resource: it runs the smarthome domain agent action 'chat'. It differentiates from smarthome-specific siblings like smarthome_command_plan and smarthome_status_report by naming the generic chat action, though it does not contrast with other domain-specific chat tools.

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 provides no explicit guidance on when to use this tool versus alternatives such as smarthome_command_plan, smarthome_scene_assist, or dispatch_domain_agent. The 'free-text objective' hint implies general conversational use, but there is no stated selection criteria, exclusions, or routing advice.

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