Trace GenLayer Transaction

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

Annotations already declare readOnlyHint=true and idempotentHint=true, so the description's mention of calling a debug method adds context without contradicting. The condition about node exposing debug methods is additional behavioral guidance beyond annotations, but no further side effects are described. This is appropriate given annotation coverage.

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 a single sentence that efficiently conveys the action, method, and condition. No extraneous words. It is front-loaded with the core purpose and immediately useful.

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 tool has no output schema, the description omits return value details, but the trace output can be inferred. The condition about debug methods is a valuable completeness element. Overall, the description meets the basics for an agent to use the tool effectively, though adding a comment about the trace output format would improve it.

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%—both parameters have descriptions in the schema (txID with 'Transaction hash with 0x prefix' and round with 'Optional appeal round to inspect'). The tool description does not add extra semantic value beyond what the schema provides, so a baseline score of 3 is warranted.

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 states the action ('trace a transaction'), the method ('gen_dbg_traceTransaction'), and the resource ('transaction hash'). It distinguishes this tool from many transaction-related siblings by specifying the dependency on debug methods. This is specific and actionable.

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 description explicitly conditions use on the target node exposing debug methods, providing clear context. It does not list exclusions or alternatives, but among many sibling tools that handle transactions (e.g., genlayer_inspect_transaction, genlayer_get_transaction_status), the debug method requirement effectively differentiates usage.

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