Hub Status

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

With no annotations, the description carries the full burden. It implies a read/status operation and usefully states that token presence is reported but never the token itself. However, it does not explicitly state that the call is read-only, what permissions are needed, or whether any side effects occur.

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?

It is a single dense sentence with a parenthetical list, so it is concise in size but poorly structured and not front-loaded. The wording is hard to parse and does not lead with a clear action.

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?

This is a zero-parameter status tool with an output schema, so return values do not need full explanation. The description lists relevant state categories and a token-safety note, but its fragmentary phrasing and lack of usage orientation leave it only partially complete.

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 and full schema coverage, so there are no parameter semantics to clarify. The baseline score of 4 is appropriate.

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?

It enumerates the state the tool reports (hub, places, watchers, hub_pause) but is a sentence fragment with no verb. The scope is inferable from the name and list, but it does not clearly distinguish hub_status from siblings like hub_presence, hub_watch, or hub_read.

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?

There is no when-to-use guidance, no prerequisites, and no named alternatives. The mention of hub_pause is only as returned data, not as guidance about when to call this tool.

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