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

Annotations already convey read-only, idempotent, non-destructive behavior, so the description need not repeat them. It adds the useful detail that the tool detects failed or erroring contract executions, but does not explain output semantics, error cases, or chainid defaulting. This is adequate but not deeply transparent.

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?

A single front-loaded sentence with a useful parenthetical; no filler or repetition of the schema. It earns its place.

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 is simple, params are fully documented, and annotations cover side-effect safety, but there is no output schema or stated return format. A caller can invoke it, but less clear what exact status values/results to expect and how they differ from receipt-based status tools.

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 description coverage is 100%, so the baseline is 3. The description adds no parameter-level meaning beyond what the schema already documents for txhash and chainid.

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 operation ('Get the contract execution status') and the resource (transaction), and adds the useful detail that it detects failed/erroring executions. It is understandable on its own, though it does not explicitly distinguish it from the closely named sibling get_transaction_receipt_status.

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 is given about when to use this tool instead of alternatives such as get_transaction_receipt_status, get_transaction_receipt, or get_transaction_by_hash. The description implies a status check but does not state exclusions or preference conditions.

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