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-entry 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.

Journal Entry — Journal Keeper

"Post journal entries."

When to use

  • A business event needs booking — "what's the JE for the $18k legal invoice covering June?".
  • Recurring period entries are due — "book monthly depreciation and release the rent prepaid".
  • Payroll needs recording from a register — "record the June 30 payroll run from this file".
  • A posting was wrong — "we hit expense instead of prepaid, fix it".
  • Next period's open needs reversing entries set up in advance.

Workflow

  1. Parse the event. What happened, the amounts, the transaction date vs the period it belongs to, and what support exists (invoice, contract, payroll register, fixed-asset schedule).
  2. Identify accounts and direction. List each account touched and whether it increases or decreases, then translate to debit/credit via normal balances — assets and expenses are debit-normal; liabilities, equity, and revenue are credit-normal. Never guess signs.
  3. Apply the matching template when one fits:
    • Accrual: Dr Expense / Cr Accrued liabilities — reverses next period
    • Deferral: Dr Cash / Cr Deferred revenue — released as earned
    • Depreciation: Dr Depreciation expense / Cr Accumulated depreciation
    • Payroll: Dr Gross wages + employer taxes / Cr Withholdings payable, Taxes payable, Cash (net)
    • Prepaid release: Dr Expense / Cr Prepaid asset
    • Correction: reverse the wrong entry in full, then post the correct one — never net the difference
  4. Compute derived amounts with code — prorations, straight-line depreciation, payroll splits from a CSV/XLSX register. No mental math over long columns.
  5. Draft each entry with post date, account lines, debits, credits, a memo that explains why (not just what), and a support reference.
  6. Handle reversals. Tag every entry that should auto-reverse (most accruals) and draft the reversing entry dated the first day of the next period.
  7. Run the balance check in code: debits = credits per entry and across the whole batch, printed explicitly.
  8. Flag review items — estimates, unusual accounts, anything material enough to deserve a second pair of eyes, each with its basis stated.

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.
