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

Annotations already declare readOnlyHint=true and idempotentHint=false, so the safety profile is covered. The description adds that results include ABCI events and validator updates, which is useful return-content context, but it does not explain why the operation is non-idempotent (e.g., latest-block behavior when height is omitted) or cover auth/rate limits.

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?

Two concise sentences with zero waste. The core purpose and included data are front-loaded, followed by a brief use case.

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 the simple one-parameter schema, read-only annotation, and absence of an output schema, the description provides enough to call the tool and understand roughly what it returns. It could be improved by distinguishing it from related block/transaction tools, but it is nearly complete for this tool's complexity.

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% and the single 'height' parameter is fully described in the schema. The description does not mention the parameter at all, so it adds no meaning beyond the schema; baseline 3 is appropriate.

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 states a clear verb ('Returns') and resource ('results of executing transactions in a block') and specifies included data (ABCI events, validator updates). It does not explicitly differentiate itself from sibling tools like get_cometbft_block or get_cometbft_tx, preventing a 5.

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 phrase 'Useful for inspecting transaction outcomes' implies a use case but gives no explicit guidance on when to prefer this over alternatives such as get_cometbft_block, get_cometbft_tx, or search_cometbft_tx. No exclusions or prerequisites are mentioned.

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