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 | $0.00073 | $0.01431 |
| Opus 5 | $0.00036 | $0.00715 |
| Sonnet 5 | $0.00015 | $0.00286 |
| Haiku 4.5 | $0.00007 | $0.00143 |
Grade A, and why
"biz-dcf" 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.
This is a copy
94% identical to biz-dcf — 8 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.

Discounted Cash Flow (DCF) Valuation
Overview
DCF estimates a company's intrinsic value by projecting future free cash flows and discounting them to present value using WACC. It answers "what is this business worth based on its future cash generation ability?"
When to Use
Trigger conditions:
- User needs to value a company or business unit
- User evaluating M&A targets or investment opportunities
- User asks "what's the fair price?" or "build a valuation model"
When NOT to use:
- For early-stage startups with no revenue → use comparables or venture method
- For quick relative valuation → use multiples (P/E, EV/EBITDA)
- For portfolio-level decisions → use BCG Matrix
Framework
IRON LAW: Garbage In, Garbage Out
DCF output is ONLY as good as its assumptions. Every assumption (growth rate,
margin, WACC, terminal growth) must be explicitly stated with justification.
A DCF without an assumptions table is worthless.
IRON LAW: Terminal Value Dominates — Handle with Care
Terminal value typically represents 60-80% of total DCF value. If your
terminal growth rate exceeds long-term GDP growth (~2-3%), you're implying
the company will eventually become larger than the economy. Cap terminal
growth at the risk-free rate or GDP growth.
Step 1: Project Free Cash Flows (5-10 years)
FCF = EBIT × (1 - Tax Rate) + Depreciation - CapEx - ΔWorking Capital
Build projections from:
- Revenue growth assumptions (top-down or bottom-up)
- Operating margin trajectory
- Capital expenditure requirements
- Working capital changes
Step 2: Calculate WACC
WACC = (E/V × Re) + (D/V × Rd × (1 - Tax))
Where:
- Re = Cost of equity (use CAPM: Rf + β × Market Risk Premium)
- Rd = Cost of debt (interest rate on borrowings)
- E/V = Equity weight, D/V = Debt weight
Step 3: Calculate Terminal Value
Gordon Growth Model (preferred):
TV = FCF_final × (1 + g) / (WACC - g)
Where g = terminal growth rate (cap at 2-3%)
Exit Multiple Method (alternative):
TV = EBITDA_final × EV/EBITDA multiple

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.
