3-statement-model

3-statement-model is a skill for Claude Code, Codex from johnson7788/MultiUserClaw. It costs 54 tokens per session (4,837 once invoked), scanned A, a copy of 3-statement-model, MIT.

An Excel model linking the income statement, balance sheet, and cash-flow statement, with schedules for working capital, depreciation, amortisation, and debt. These statements show profit, financial position, and cash movement.

In plain words
What is it for?
Use it to forecast a company's finances, test scenarios, and build models where cash and retained earnings reconcile across the three statements.
Why use it?
It keeps related financial calculations connected, so changing assumptions updates the forecast and the statements continue to balance.

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

3-statement-model 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 3d 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.

Origin

This is a copy

95% identical to 3-statement-model — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 434 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Environment

This skill assumes headless openpyxl — you are producing an .xlsx file on disk. Follow the excel-author skill's conventions for cell coloring, formulas, named ranges, and sensitivity tables. Recalculate before delivery: python /path/to/excel-author/scripts/recalc.py ./out/model.xlsx.

3-Statement Financial Model Template Completion

Complete and populate integrated financial model templates with proper linkages between Income Statement, Balance Sheet, and Cash Flow Statement.

⚠️ CRITICAL PRINCIPLES — Read Before Populating Any Template

Formulas over hardcodes (non-negotiable):

  • Every projection cell, roll-forward, linkage, and subtotal MUST be an Excel formula — never a pre-computed value
  • When using Python/openpyxl: write formula strings (ws["D15"] = "=D14*(1+Assumptions!$B$5)"), NOT computed results (ws["D15"] = 12500)
  • The ONLY cells that should contain hardcoded numbers are: (1) historical actuals, (2) assumption drivers in the Assumptions tab
  • If you find yourself computing a value in Python and writing the result to a cell — STOP. Write the formula instead.
  • Why: the model must flex when scenarios toggle or assumptions change. Hardcodes break every downstream integrity check silently.

Verify step-by-step with the user:

  1. After mapping the template → show the user which tabs/sections you've identified and confirm before touching any cells
  2. After populating historicals → show the user the historical block and confirm values/periods match source data
  3. After building IS projections → run the subtotal checks, show the user the projected IS, confirm before moving to BS
  4. After building BS → show the user the balance check (Assets = L+E) for every period, confirm before moving to CF
  5. After building CF → show the user the cash tie-out (CF ending cash = BS cash), confirm before finalizing
  6. Do NOT populate the entire model end-to-end and present it complete — break at each statement, show the work, catch errors early

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.
