Robinhood Chain network health

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

With no annotations, the description carries full burden. It discloses the tool is paid (cost up to $0.005 USDC) and requires no input, which is good. However, it does not mention rate limits, authentication needs, or what happens if the chain is unhealthy. Safety profile is implied read-only but not explicitly stated.

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 two sentences: the first defines purpose and outputs, the second explains cost. Both are essential, no filler. Front-loads the core function.

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 output schema, the description lists what the tool returns. For a simple health check with no parameters, it covers key aspects. Could mention response format or latency, but overall sufficient for an agent to understand the tool's value.

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?

The input schema has zero parameters with 100% coverage. The description adds 'No input' which is clear, and also provides cost information. For zero-parameter tools, baseline is 4, and the description meets that with added context.

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 identifies the tool as a live network health monitor for Robinhood Chain, listing specific outputs (latest block, block time, gas, tx counts, ETH price). It distinguishes from sibling tools like chain_tvl or gas_oracle by focusing on overall chain status, but could be slightly more explicit about its read-only nature.

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 for quick health checks via 'No input' and 'Live network health,' but does not explicitly state when to use this tool over siblings or provide exclusions. The paid nature is mentioned, but no alternatives or conditions are given.

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