Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations, the description carries the full burden. It discloses the response contents (status, gas used, logs), which is genuine behavioral information, but says nothing about what happens for an unknown or still-pending hash, whether the call errors or returns null, or any auth/rate-limit constraints.
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 short sentences, front-loaded with the resource and return fields; nothing is padded. The second sentence partly restates the already-listed "success/failure status," which is a small redundancy but not wasteful enough to penalize more.
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?
There is no output schema and no annotations, so the description must cover behavior; it lists the returned fields but not their structure or the pending/not-found case. For a one-parameter read this is adequate to call correctly, but a receipt-specific tool should address the unavailable-receipt scenario.
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 there is only one parameter, whose format (0x + 64 hex) the schema already documents. The description's "by hash" phrasing adds no syntax or validation detail beyond the schema, so the baseline 3 applies.
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?
States a specific verb+resource (get transaction receipt) and names the identifying key (by hash), plus enumerates the payload: success/failure status, gas used, logs. That clearly separates it from sibling get_transaction, which returns the transaction itself rather than its receipt, though the description never names that sibling explicitly.
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?
"Useful for checking if a tx succeeded" gives an implied usage context, which is slightly better than nothing. But it offers no when-not guidance (e.g., use get_transaction for pending txs or for input data) and does not name any alternative among the many sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
