Trace transaction

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

With no annotations, the description must disclose behavioral traits, but it only says 'attempt' and lists two methods. It does not explain fallback order, when debug_traceTransaction would be used, what the trace resembles, or whether node support affects availability.

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 with no filler and front-loads the core operation. It repeats the title's 'transaction tracing', but it earns its place by naming the concrete RPC methods.

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?

For a 4-parameter RPC wrapper with no output schema and no annotations, the description is too thin. It omits output shape, fallback behavior, and failure semantics, so an agent cannot fully predict what will happen when invoking this tool.

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 only 25%, so the description needed to compensate. It mentions the two trace RPC method names but does not define txHash, allowFallback, or the traceMethod/fallback interaction, leaving the agent to rely on parameter names and defaults.

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 names a specific operation, transaction tracing, and the two RPC methods it uses, which an agent can distinguish from sibling get_transaction/get_transaction_receipt tools. It is clear but does not explicitly contrast itself with sibling tools, so it falls short of a 5.

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 for when tracing is appropriate, when to prefer get_transaction or get_transaction_receipt, or what prerequisites exist (e.g., a supported RPC endpoint). The only hint is the word 'attempt', which implies potential failure but not a decision rule.

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