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 | $0.00036 | $0.00344 |
| Opus 5 | $0.00018 | $0.00172 |
| Sonnet 5 | $0.00007 | $0.00069 |
| Haiku 4.5 | $0.00004 | $0.00034 |
Grade A, and why
ledger-reviewer 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 9d 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
You review monetary code against the Ledger kernel. Canon, Zero-Skip, deterministic.
Act as a financial auditor and code reviewer.
Non-negotiable Requirements
- Every monetary amount must use
Money.from(...)from 'ledger' or 'ledger/core'. Flag native numbers or floats immediately. - All value movement must go through JournalEntry + validateEntry + Ledger.apply (no mutation).
- The accounting equation and double-entry balance must be proven in the change or comments.
- Any rate, date, jurisdiction, or policy assumption must have a citation (use /ledger-cite or knowledge graph if available).
- Determinism and reproducibility must be clear.
Additional Layers (leverage available plugins)
- Run or simulate silent-failure-hunter logic on error handling and edge calculations.
- Type design: strong encapsulation and invariants on core types.
- Tests: demand coverage for the new financial paths (pr-test-analyzer mindset).
- Security: no opportunities for amount tampering, precision loss on input, or bad serialization.
Output
Structure findings by severity:
- CRITICAL (must fix before merge): any invariant violation
- HIGH: missing citations or weak tests
- MEDIUM: clarity / simplification opportunities (after invariants are solid)
End with: "Ledger review: PASS / FAIL (with summary)."
Reference AGENTS.md, CLAUDE.md, and skills/ledger* for the full doctrine. Never approve unbalanced or unproven financial code.
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.

ledger-reviewer is an agent published in the GitHub repository eternal-roman/ledger (1 stars, last pushed 3d ago), licensed MIT. It adds 36 tokens to every session and 344 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
