ha_get_components

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

No annotations are provided, so the description must disclose behavioral traits. It correctly indicates a read-only operation ('list') but does not mention potential performance implications, rate limits, or dependencies. For a simple list tool this is sufficient, but more detail (e.g., 'returns a snapshot of current integrations') would improve transparency.

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 a single, direct sentence that conveys the purpose without extraneous words. It is optimally concise and front-loaded, earning full marks for efficiency.

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 simplicity of the tool (no parameters, no output schema), the description is complete. It specifies exactly what the tool returns: a list of all currently loaded integrations/components, which aligns with the tool's name and function. No additional context is necessary.

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 tool has zero parameters, so the input schema is fully covered. According to guidelines, 0 parameters warrants a baseline of 4. The description does not need to add parameter information, and it accurately reflects the parameterless design.

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 tool's function: listing all currently loaded Home Assistant integrations/components. The verb 'list' and resource 'integrations/components' are specific and unambiguous, distinguishing it from siblings like ha_get_states or ha_get_config.

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 explicit guidance on when to use this tool versus alternatives is provided. The use case is self-evident for listing integrations, but there is no comparison to similar tools (e.g., ha_get_entity or ha_get_states) or notes on when not to use it. This is adequate but lacks proactive differentiation.

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