getBeaconNodeVersion

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

No annotations provided; description gives no behavioral details (e.g., error conditions, rate limits, output format). Only states the basic function without any caveats or notes about the version string.

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?

Extremely concise: a single, front-loaded sentence that directly conveys the tool's purpose. No extraneous words.

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 no annotations and no output schema, the description is adequate for a simple version fetch but lacks context about return value format or prerequisites (e.g., needing a beacon node). It is minimally viable.

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% (parameter 'network' fully described). The description adds no additional meaning beyond the schema; it simply restates the tool's purpose without elaborating on 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 ('Get') and the resource ('software version string of the Beacon Chain node'). It uniquely identifies what this tool does relative to many sibling beacon tools (e.g., getBeaconBlock, getBeaconHeaders).

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 guidance on when to use this tool versus alternatives (e.g., when to get version vs. sync status or block). No when-to-use or when-not-to-use context.

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