getBeaconStateRandao

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

No annotations provide behavioral context, and the description omits details such as return format, error conditions, or permission requirements, leaving the agent to infer behavior from the tool name.

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?

Single sentence, front-loaded with key information, no filler or repetition.

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?

Adequately describes purpose but lacks output schema details and behavioral hints; given three parameters and no annotations, more context on expected output or usage examples would improve 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%, so the baseline is 3; the description adds no extra meaning beyond the schema's parameter descriptions, which are clear but not enhanced.

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 specifies the verb ('Get'), resource ('RANDAO mix value'), and scope ('for a given Beacon Chain state and optional epoch'), accurately distinguishing it from sibling tools that retrieve other beacon state data.

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; with many sibling getBeaconState tools, an agent would benefit from explicit when-to-use and exclusion criteria.

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