Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00030 | $0.01988 |
| Opus 5 | $0.00015 | $0.00994 |
| Sonnet 5 | $0.00006 | $0.00398 |
| Haiku 4.5 | $0.00003 | $0.00199 |
Grade A, and why
ledger-management 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 11d 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.

Ledger Management
Purpose
The general ledger is the single source of truth for every financial transaction. This skill designs and maintains the chart of accounts, records journal entries, performs month-end adjustments, reconciles subledgers, and produces the trial balance. Without it, financial data is fragmented, the trial balance doesn't balance, and financial statements cannot be trusted.
When to Use
- "Update the general ledger / post these entries"
- "Design / review our chart of accounts"
- "Record this journal entry / adjustment"
- "What accounts do we have?"
- "Reconcile this account"
- "Produce a trial balance"
Inputs Required
- Chart of accounts — if none exists, build one. If one exists, read it.
- Transaction batches — from
transaction-processing,accounts-payable-management,accounts-receivable-management,payroll-processing. - Bank feeds — for cash account reconciliation.
- Prior period trial balance — for opening balances.
Quick Reference
| Concept | Description | Example |
|---|---|---|
| Journal Entry | Balanced debit/credit record for every transaction | DR AR $10k / CR Revenue $10k |
| Trial Balance | Summary of all account balances with debits = credits | Every asset, liability, equity, revenue, expense account |
| Chart of Accounts | Numbered hierarchy of all accounts (1000-9999) | 1000 Cash, 2000 AP, 4000 Revenue, 6000 R&D |
| Accrual Basis | Revenue/expenses recorded when earned/incurred, not when cash moves | Bill in March, collect in April → record revenue in March |
| Account Reconciliation | Matching GL balance to external source (bank, subledger) | Cash GL balance = bank statement balance |
| Materiality Threshold | $500 minimum for adjustments in startups < $1M annual spend | Don't waste time on $200 prepaid amortization |
Procedure
1. Journal Entry Creation
For every transaction, create a balanced journal entry:
- Date: transaction date.
- Description: concise, searchable (include vendor name, invoice #).
- Debits = Credits: ALWAYS. The system should verify this.
- Supporting reference: link to invoice, receipt, contract, or approval.
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-management is a skill published in the GitHub repository gokulb20/crewm8-cfo-skills (2 stars, last pushed 4mo ago), licensed MIT. It adds 30 tokens to every session and 1,988 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings.

Use when a small business needs audit-ready books — a chart of accounts, posting a transaction to the right account and side, clearing an uncategorized bank feed, cash vs accrual, or a ledger that won't tie to the bank.
