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

transaction-analyzer 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 2mo 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

Transaction Analyzer Skill

Provides comprehensive Ethereum transaction analysis:

  • Get transaction details (from, to, value, gas, input data)
  • Get transaction receipt and status
  • Analyze gas usage (gas used vs gas limit)
  • Calculate actual transaction cost
  • Get internal transactions/transfers
  • Decode token transfer events (ERC20, ERC721)
  • Get transaction confirmation time

Use builtin_transaction_analyzer tool with fields:

  • operation: one of "details", "receipt", "gas_analysis", "cost", "token_transfers", "internal_txs"
  • tx_hash: transaction hash to analyze
  • network: (optional) Ethereum network: "mainnet", "sepolia", "holesky" (default: "mainnet")

Note: All operations are read-only analysis. No transaction modification is possible.

Changes

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.
