operate_node_module

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing. It does not say whether the operation mutates state, which operations are supported, whether it is destructive or reversible, what permissions or XPack licensing it requires, or what the response contains. The nested params object is entirely opaque.

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 short, but shortness here reflects under-specification rather than efficiency. A five-word fragment that conveys neither purpose nor usage does not earn 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 two-parameter mutation-style tool with a bare nested params object, no annotations, and no output schema, the definition is unusable as written. Nothing tells the agent what the tool does, when to use it, or how to populate its required inputs.

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 description coverage is 0% for both required parameters, and the description adds no meaning whatsoever. The critical "params" object has no documented shape or keys, so an agent has no way to construct a valid call.

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?

"Operate Node module (XPack)" mostly restates the tool name with an undefined verb. "Operate" could mean install, update, enable, disable, or remove, and the sibling set (get_node_modules, get_node_package_scripts) gives no clue what operation this performs. Only the "XPack" parenthetical adds any information at all.

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 pointer to any alternative tool. An agent cannot tell from this text when to call operate_node_module rather than get_node_modules or anything else.

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