test_check_mlx

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

No annotations are provided, so the description must carry the full burden of behavioral disclosure. It only states 'Check' without specifying whether the tool makes network calls, what actions it takes (e.g., ping, request endpoint), or what side effects may occur. The agent is left guessing about safety and side effects.

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, focused sentence with no filler. It efficiently conveys the tool's purpose without redundancy.

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?

Given the tool's purpose and lack of output schema or annotations, the description is incomplete. It does not explain what the tool returns (e.g., health status, boolean), how it handles failures, or what 'compatibility' means in practice. The minimal description leaves significant gaps for an agent to invoke the tool correctly.

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 100% for both parameters, with descriptions for mlxUrl (including default) and projectPath. The description adds no additional parameter context beyond what the schema already provides, so the baseline of 3 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?

The description clearly states the tool's function: checking health and platform compatibility of an MLX local LLM server. The verb 'Check' combined with the specific resource 'MLX local LLM server' and additional 'Apple Silicon platform compatibility' distinguishes it from sibling tools, which are mostly game-state or scene related.

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 usage as a preflight health check but offers no explicit guidance on when to use it versus alternatives. Sibling tools are listed, but no direction is provided for choosing this tool for health verification.

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