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 discloses failure behavior (an error will explain how to enable the addon), which is useful. But it doesn't state what a successful response looks like or any timeout/retry characteristics.

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?

Two short sentences, front-loaded with the core purpose followed by the ordering instruction. No wasted words; appropriate for a simple connectivity check.

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 connectivity check with no output schema, the description covers purpose, usage order, and failure mode. It could mention what success returns, but the essential information an agent needs is present.

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?

There are 0 parameters with 100% schema coverage, so the baseline is 4. The description correctly implies a parameterless invocation and adds no confusing parameter information.

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?

States a specific verb+resource: 'Kiem tra' (check) whether the MCP server can connect to Blender. Its purpose as a connectivity/health check is clear and distinguishable from sibling tools like xem_canh or render_anh. It doesn't explicitly contrast with a sibling, so not a 5.

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?

Explicitly says 'Goi tool nay dau tien' (call this tool first), giving clear usage ordering guidance. It also tells the agent what happens on failure (error message will point to how to enable the addon). However it doesn't state when-not-to-use or name alternatives.

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