get_homelab_overview

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

The description discloses that partial results are returned if individual services are unreachable, which adds valuable behavioral context beyond the readOnlyHint annotation. It also sets expectations by listing the components included.

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, well-structured sentence that front-loads the tool's purpose and uses a colon-separated list for specifics. It is concise with no wasted words.

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 zero-parameter, read-only tool with an output schema, the description covers purpose, content, and a key behavioral caveat. It is slightly incomplete in not situating the tool among sibling overview tools, but overall it is sufficient for selection and invocation.

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 no parameters, so the schema is inherently 100% covered. The zero-parameter baseline of 4 applies; the description adds no parameter information but none is needed.

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 as a complete homelab overview, enumerating specific data categories (host health, container counts, storage, media streams, errors, speed test results). This differentiates it from narrower sibling tools like get_service_info or get_media_overview.

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 implies a general overview use case but does not explicitly state when to use this tool versus alternatives such as get_infra_overview or get_media_overview. No exclusions or comparisons are provided.

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