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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01067 | $0.01067 |
| Opus 5 | $0.00534 | $0.00534 |
| Sonnet 5 | $0.00213 | $0.00213 |
| Haiku 4.5 | $0.00107 | $0.00107 |
Grade A, and why
bookkeeper-starter CLAUDE.md 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Bookkeeper — AI Bookkeeping OS (multi-client)
A productized bookkeeping system: per-client Google Sheets double-entry ledgers +
Drive PDF archives, operated by deterministic tools behind human approval gates.
Every command takes --client <slug>; with no flag it acts on DEFAULT_CLIENT
(sandbox-demo, the bundled example tenant). New here? Start with
README.md. Docs: docs/PRODUCT.md (what/who),
docs/ARCHITECTURE.md (how), docs/CONTROLS.md
(trust model), docs/LIMITATIONS.md (honest boundaries).

Key invariants (do not break)
- One Journal writer: every JE goes through
post_je()— COA check, Dr=Cr, period lock, dedupe key, audit log. Never append to Journal any other way. - Additive-only sheet schema: Invoices A–R frozen; new columns only to the right. Journal Q = Dedupe Key, Expenses Q = Txn ID.
- Contract surface (the skills depend on it):
mark_invoice_paid.pyflags,clients/<slug>/customers.jsonviactx.customers_path,sheets_client.pypath. Run./tests/contract_test.shafter any change. - No silent guessing: uncertainty →
exceptions_queue, never the books. - Confirm every cloud write: dry-run → user OK →
--commit. - Locked periods are immutable: corrections per workflows/corrections.md.
- Judgment lives in workflows/packs/profiles — never hardcoded in tools.
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.
