get_block_rewards

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

With no annotations, the description bears full responsibility for behavioral disclosure. It only states 'Estimate' without clarifying whether this is a read-only operation, whether the estimate is approximate by nature, or what the response contains. No information about authentication, rate limits, or network-specific behavior is provided.

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, front-loaded sentence that clearly communicates the core action. Every word contributes value, with no redundancy or unnecessary detail.

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?

The tool lacks an output schema and annotations, so the description must explain return values and behavioral caveats. It doesn't mention what the reward estimate looks like (e.g., currency, units, whether it's per validator or total). The description is too terse to be fully useful for an agent deciding on invocation.

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 schema provides 100% coverage with detailed descriptions for both parameters (network and blockNumber), so the baseline is 3. The description adds no additional meaning beyond the schema; the 'specific block' phrase merely echoes the blockNumber 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 uses a specific verb ('Estimate') and resource ('block rewards') with a clear scope ('for miners/validators on a specific block'). This distinguishes it from sibling tools like get_block_by_number or get_block_receipts, which focus on block details rather than reward estimation.

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 provides no guidance on when to use this tool versus alternatives. There is no mention of using get_blocks_by_miner for block lists or get_block_by_number for block details, nor any exclusions. The use case is implied but not differentiated from the many block-related siblings.

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