xlayer_call

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

No annotations are provided. The description hints at a write operation with '[L:WRITE]' but does not clarify side effects, authorization requirements, rate limits, or return behavior. The prerequisite hint is vague.

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 very short (one line) but lacks clarity and proper structure. It uses cryptic tags and does not front-load a clear purpose. It is under-specified rather than concise.

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 complexity of a JSON-RPC call tool with no output schema, the description is severely incomplete. It does not explain the tool's function, return values, or usage, and the prerequisite instruction is minimal.

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% with descriptions for both 'method' and 'params' parameters. The description adds no additional meaning beyond what the schema already provides, so baseline score of 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 does not explicitly state what the tool does. It includes a cryptic label '[L:WRITE]' and category 'CAT:[链上]' but fails to explain that this tool performs JSON-RPC calls to the Xlayer blockchain. The purpose is only implied by the tool name and input schema.

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 alternatives. The description only says 'call agent_catalog first', which is a prerequisite but does not help an agent choose between this and sibling tools like xlayer_get_events or xlayer_subscribe.

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