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

journal 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 5d 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

Journal

Record journal entries for "$ARGUMENTS". Convert analyzed transactions into formal double-entry journal entries with equal debits and credits.

Prerequisites

Read .metapowers/accounting/$ARGUMENTS/01-analyze.md for the transaction register and chart of accounts.

Process

  1. Review the transaction register:

    • Load the analysis artifact from Phase 1
    • Confirm all transactions are accounted for
    • Resolve any flagged items before journalizing
  2. Create journal entries:

    • For each transaction, record:
      • Date — when the transaction occurred
      • Accounts — debit account(s) and credit account(s)
      • Amounts — debit and credit amounts (must be equal)
      • Description — brief explanation of the transaction
    • Number entries sequentially (JE-001, JE-002, etc.)
  3. Validate entries:

    • Every entry must have at least one debit and one credit
    • Total debits must equal total credits for each entry
    • Verify account names match the chart of accounts
    • Flag compound entries (more than two accounts) with clear explanations
  4. Write the artifact to .metapowers/accounting/$ARGUMENTS/02-journal.md with sections:

    • General Journal — all entries in chronological order with debit/credit columns
    • Entry Summary — count of entries by type (revenue, expense, asset, liability)
    • Validation — confirmation that all entries balance

Output

The journal written to .metapowers/accounting/$ARGUMENTS/02-journal.md. Present a summary highlighting:

  • Total number of journal entries
  • Total debits and credits (should match)
  • Any compound or noteworthy entries
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.
