freebuff_status

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

With no annotations provided, the description carries the behavioral disclosure burden. 'Check whether' signals a non-mutating verification and describes exactly what is checked (credentials, backend reachability). However, it does not mention possible side effects, network behavior, or what happens when credentials are invalid.

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?

A single sentence that front-loads the action and directly states the tool's purpose with no filler, repetition, or unnecessary detail. Every word earns its place.

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-input status tool, this is nearly complete: an agent can select and invoke it correctly based on the description alone. The main gap is the absence of return-value/output details, which matters more because there is no output schema and no annotations to clarify what the check returns.

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 the schema is complete, so there is no parameter semantics burden. Per the rubric, a zero-parameter tool with full schema coverage gets a baseline of 4; the description adds no parameter information and does not need to.

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 names a specific action ('Check whether') and a specific resource/condition (Freebuff MCP server credentials and agent backend reachability). This clearly distinguishes it from the operational siblings freebuff_run, freebuff_delete, freebuff_stop, and freebuff_sessions, which all imply different purposes.

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 health/credential-check use case, likely as a precondition before running other Freebuff commands, but it does not explicitly state when to use this tool versus siblings or when not to use it. Usage context is present but left to inference.

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