Rustchain Transfer Signed

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

No annotations are present, so the description carries the full disclosure burden. The only behavioral fact it adds is the Ed25519 signature requirement, which is genuinely useful. But for a mutating financial operation, it fails to disclose that the transfer permanently changes ledger state, what role nonce plays, or how the result should be interpreted.

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 the signature constraint neatly parenthesized and the key fact front-loaded. There is zero filler. It loses a point only because the compact form omits usage and behavioral context that a transfer operation needs.

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 output schema covers return values and the schema covers most parameters, which reduces the burden. Still, for a 7-parameter mutating transfer with no annotations, the description omits the meaning of nonce, whether the transaction is broadcast on-chain, and any differentiation from wallet_transfer_signed — real gaps for an agent deciding whether and how to call it.

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 86%, so the baseline of 3 applies; the schema already documents from_address, to_address, amount_rtc, signature, public_key, and memo. The description reinforces the signature requirement but adds no parameter-level meaning, and notably fails to clarify the one cryptic parameter, nonce, which has no description in the schema.

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 verb ('Transfer') and resource ('RTC tokens between wallets'), and adds the key constraint that an Ed25519 signature is required. This clearly separates it from read-style Rustchain siblings like rustchain_balance and rustchain_stats. However, it never explicitly distinguishes itself from the near-twin sibling wallet_transfer_signed, leaving the agent to guess which 'transfer signed' variant applies.

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 when-to-use guidance or alternative routing appears in the description. With siblings like wallet_transfer_signed, rustchain_create_wallet, and rustchain_balance nearby, the agent gets no direction about prerequisites (existing wallet, sufficient balance, generating the signature first) or which sibling to prefer under other conditions.

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