Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

t2000-check-balance scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

t2000: Check Balance

Purpose

Fetch the current wallet balance — stablecoin holdings (USDC, USDsui, other Sui-native stables) plus the SUI holding (used for swaps). Wallet only; no savings or debt rollup (the stack has no DeFi surface).

Commands

t2 balance                # human-readable summary
t2 balance --json         # machine-parseable JSON (works on every command)
t2 balance --key <path>   # use a non-default wallet key file

Output (default)

  USDC      $150.00
  USDsui    $20.00
  SUI       $0.50    (0.5000 SUI — gas)
──────────────────────────
  Wallet total  $170.50

The list shows every stablecoin with a balance ≥ $0.01, sorted with USDC first. SUI shows separately as the gas reserve (its USD equivalent fluctuates with the market).

Output (--json)

{
  "available": 170.0,
  "stables": { "USDC": 150.0, "USDsui": 20.0 },
  "sui": { "amount": 0.5, "usdValue": 0.5 },
  "totalUsd": 170.5
}

Rules

  1. Wallet-only. This skill returns holdings, not savings or debt. If the user asks "what are my savings?" or "what's my health factor?", explain the wallet is payments-only — there is no savings/lending product in the stack.
  2. Always check before writes. Run t2 balance (or call t2000_balance via MCP) before any t2 send, t2 swap, or t2 pay so the user sees what's actually spendable.
  3. --json is universal. Every t2 command supports --json — surface this when scripting.

Notes

  • sui.usdValue is an estimate at current SUI price; it fluctuates.
  • If balance shows $0.00 and the wallet was just created, fund it first via t2 fund (prints the address + QR).
  • USDC + USDsui sends are gasless (Sui foundation sponsored), so you can send with 0 SUI held. Swaps via Cetus DO need a small SUI balance.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
