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

Annotations already declare the safety profile (non-read-only, open-world, non-destructive), and the description usefully adds that it runs in-chat with no browser and defaults to the saved wallet. However, for a faucet the key behavioral trait is rate limiting / repeat-claim behavior and the amount dispensed, none of which is disclosed.

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?

Three short, front-loaded sentences with no wasted words; the default-wallet behavior is stated before the use case. 'Works instantly in chat, no browser' leans slightly promotional but does carry real behavioral information.

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 one-optional-param tool with no output schema this is close to sufficient, but an agent cannot tell what it receives back (amount of AGENT, tx hash) or whether repeated calls are permitted. Those gaps are minor but not fully covered elsewhere.

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% and the single optional address parameter is fully documented there. The description's 'defaults to your saved wallet' restates the schema's 'omit to use your wallet' rather than adding format or validation detail, so baseline 3 applies.

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?

States a specific action (claim AGENT from a faucet) with a clear resource, and the title clarifies the otherwise ambiguous verb 'mine'. It is distinguishable from siblings like create_wallet, balance, or send, though it never names a sibling to sharpen the distinction.

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?

'Use to fund a fresh wallet for gas' gives a concrete trigger condition for calling it, which is more than most faucet-style tools offer. It stops short of naming an alternative (e.g., send/swap) or stating when not to call it.

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