Wallet address

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

The annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, so the safety profile is fully covered. The description adds operationally useful context about funding the returned address with the shielded asset plus native gas. It does not say what the return value looks like (format, chain prefix) or whether the address is stable across sessions.

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?

Two short sentences, zero filler, with the core fact (this returns the wallet address) front-loaded and the funding hint following as supporting context. Every sentence earns its place.

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 zero-parameter read with rich annotations and no output schema, this is nearly complete; the funding guidance covers the main follow-up action. The only real gap is not characterizing the returned address format, which matters slightly because no output schema exists.

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 tool takes no parameters and the schema is trivially complete, so the baseline is 4. The description correctly implies a no-input read that simply yields the wallet address, leaving nothing ambiguous.

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 resource, the agent wallet's address, and is clearly distinguishable from siblings such as blackpool_balance, blackpool_send and blackpool_deposit. It lacks an explicit retrieval verb such as 'returns' or 'get', so it falls just short of the crisp verb+resource form.

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?

It gives an implicit use case: call this so you can fund the wallet with the asset to shield plus native gas before depositing. It never states when to call it versus blackpool_balance, nor any precondition such as needing the wallet initialized, so usage is inferred rather than spelled out.

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