open-context_get_node_info

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

The description mentions caching, which is a behavioral trait beyond the schema. However, without annotations, it does not disclose other behaviors like authentication needs, rate limits, or whether the fetch is read-only. The caching disclosure is a positive but minimal.

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 that conveys the tool's purpose without unnecessary words. It is concise and front-loaded, though it could optionally include more detail without harming conciseness.

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?

With no output schema and only minimal context from the description, the tool definition lacks details about the return format or what 'information' encompasses. It is adequate for a simple fetch tool but could provide more context for completeness.

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 the single parameter 'version', and the description does not add additional meaning beyond what the schema already provides. Baseline 3 is appropriate as the description adds no extra context for the parameter.

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 action ('fetch and cache'), the resource ('information about Node.js versions'), and the source ('from nodejs.org'). It distinguishes itself from siblings, which are other technology-specific info tools.

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?

No explicit guidance on when to use this tool versus alternatives. The name and description imply it's for Node.js version info, but there is no mention of when to use or not use it, or any prerequisites.

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