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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so safety is covered. The description adds real value by disclosing the response contents (token transfers, cross-chain leg, internal calls), which matters since there is no output schema, but it says nothing about behavior for unknown hashes or partial/failed transactions.

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?

One front-loaded sentence with no filler; the enumerations of returned data are the useful payload. It is a fragment rather than a full sentence, but that costs nothing in clarity.

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?

With no output schema, the field enumeration carries meaningful weight, and one required parameter is easy to infer. Still missing hash format/validation expectations and any note on error or not-found behavior, which an agent would need to call it reliably.

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 0% and the single 'hash' property has no description. The text implies the input identifies a transaction but never states the expected hash format (0x-prefixed, length) or whether it is a Wanchain tx hash versus a cross-chain message id.

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?

Specific verb and resource ('Full detail for a Wanchain transaction') plus an enumeration of what the detail contains (core fields, token transfers, cross-chain leg, internal calls). This clearly separates it from address-level siblings like get_address_summary and get_address_crosschain, though it does not explicitly name an alternative.

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 on when to use this tool versus neighboring lookups such as get_address_activity or get_crosschain_stats, and no prerequisites (e.g., hash format or chain assumption) stated. Usage is only inferable from the name and the field list.

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