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

With no annotations, the description carries the full transparency burden. It reveals that data comes from a public explorer index and that the caller pays $0.005/call, which implies a read-only query rather than a mutating operation. However, it leaves the important qualifier 'bounded transfers' unexplained, and mentions nothing about auth, rate limits, or error behavior.

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 sentence with no filler. It packs the action, target, scope, data source, and pricing into a compact front-loaded string, making it easy to scan and understand.

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?

The tool is low-complexity with one parameter and no output schema, and the description does give scope and source. But it does not explain what 'bounded transfers' means, nor does it differentiate itself among a large set of sibling wallet tools, leaving some ambiguity about the exact deliverable and boundaries of the analysis.

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?

The schema has a self-explanatory wallet_address with a strong regex, and the description supplies domain context by specifying that the address is a Base wallet and that the analysis comes from a public index. For a single parameter this is sufficient to compensate for the 0% schema-description coverage.

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 uses a specific verb ('Analyze') and names a clear resource (Base wallet), then enumerates the exact analysis scope: balances, bounded transfers, token holdings, and counterparties. It does not explicitly differentiate from sibling tools like base_wallet_profile or base_transfer_search, but an agent can infer the general purpose without opening the 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 is given about when to prefer this tool over any of the many wallet- or transfer-related siblings (e.g., base_wallet_profile, base_transfer_search, base_usdc_balance). An agent is left guessing whether to call this versus a more-specific sibling for a given need.

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