vibemk_start_service_discovery

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

No annotations are provided, so the description carries the full burden. It only says 'Start service discovery' and 'Automatically detect services,' but does not disclose whether this is asynchronous, whether it triggers a background job, whether changes require activation, or what side effects different modes may have.

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?

Extremely concise and front-loaded. The core purpose is communicated in a single short line with no filler.

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?

The description is incomplete for the complexity of the tool. It omits mode semantics, async behavior, relationship to bulk discovery, and whether the operation requires later status checks or activation changes.

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 high: both host_name and mode have descriptions. The description adds little beyond the schema; mode's enum values are listed but their meanings are not explained, and host_name is only minimally described.

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?

Clearly states the action ('Start service discovery') and target ('on a host'), with a plain-language outcome ('Automatically detect services'). It is distinguishable from bulk discovery by singular 'host', though it does not name sibling tools or explain mode variants.

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 on when to use this tool versus alternatives like vibemk_start_bulk_discovery or vibemk_discover_services. The description does not explain which mode to choose or when discovery should be run.

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