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

With no annotations, the description carries full behavioral burden. It discloses that both mined and pending transactions are retrievable and that a fingerprint is included, which is useful. However, it omits whether the operation is read-only, idempotent, or any side effects. The safety profile is implied but not stated.

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 the core action ('Fetch a transaction by id') is front-loaded. Every word adds value, and it avoids redundancy with the tool name or schema.

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 simple single-parameter fetch with no output schema, the description explains what is returned (the transaction plus fingerprint) and the scope (mined/pending). It doesn't elaborate on error cases or output structure, but these are not required given the simplicity and lack of output schema. The description is complete enough for an agent to invoke correctly.

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 0%, so the description must explain the parameter. It says 'by id' which clarifies that txId is the transaction identifier, but doesn't specify format, validation, or expected length. For a single string parameter, this is adequate but minimal—it barely compensates for the missing schema documentation.

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 states a specific verb ('Fetch') and resource ('a transaction by id') and adds two clarifying details: mined/pending status and quantum-shield fingerprint. This distinguishes it from sibling tools like aman_chain_info or aman_price, which are not about fetching transactions.

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 implies usage (when you need transaction details by ID) but provides no explicit when-not-to-use guidance or references to alternatives. It doesn't state exclusions or conditions, so it meets the 'implied usage' level but lacks explicit routing.

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