Two tools with basic schemas and descriptions, but significant gaps in parameter documentation and error handling. Tool names follow verb_noun pattern (stake-mon, withdraw-mon), which is good. Descriptions are present but generic (60-80 chars, below the 194-char baseline for A+ tools). Input schemas exist with regex patterns for amount validation, but lack comprehensive error guidance. No output schema documented. No error recovery hints. Referral ID parameter is nullable but lacks clear guidance on when/why to use it. Missing idempotency guarantees for write operations.

• Add output schema documenting: transaction_hash, gMON_minted (for stake) or MON_received (for withdraw), block_number, timestamp, explorer_url. Include these in responses so agents can confirm success and provide users with transaction links.
• Expand tool descriptions to 150-250 chars. Include prerequisites ('Requires MON balance on Monad Testnet'), side effects ('Mints gMON at 1:1 ratio'), and when to use each tool ('Use to earn staking rewards; withdraw anytime').
• Add error recovery hints in tool descriptions: 'If balance insufficient, fund wallet first. If contract paused, check Magma status page. If max TVL reached, try again later.'
• Document referralId: 'Optional numeric referral ID (0-999999). Include to earn referral rewards. Omit for standard staking.' Add enum or pattern constraint if there are known valid ranges.
• Declare idempotency: 'Staking is idempotent, calling twice with same amount and referralId produces one transaction. Withdrawal is idempotent by gMON amount.' This guides agent retry logic.

• Relies on Logging (deprecated) - log to stderr or use OpenTelemetry
