neqsim-asset-value-npv-screening

neqsim-asset-value-npv-screening is a skill for Claude Code, Codex from equinor/neqsim-community-skills. It costs 89 tokens per session (1,370 once invoked), scanned A, original, Apache-2.0.

A screening discounted-cash-flow model for estimating an asset’s net present value, internal rate of return, and payback. It combines yearly revenue, operating costs, and capital spending while accounting for the time value of money.

In plain words
What is it for?
It helps build yearly net cash flow, discount future cash flows, apply a simple tax rate, and estimate NPV, IRR, and payback from production and cost assumptions.
Why use it?
It gives a first financial view of a project before detailed field-development economics or fiscal modelling. It makes the yearly cash-flow assumptions explicit.

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

neqsim-asset-value-npv-screening 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 19d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (examples/basic_asset_value.py, src/asset_value_npv_screening/__init__.py, src/asset_value_npv_screening/model.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Asset Value (NPV) Screening

Use this skill for a quick, public discounted-cash-flow (DCF) screening of an asset. Given a year-by-year revenue series, an OPEX series (or a flat value), and a CAPEX schedule (or a single year-0 spend), it computes net cash flow, discounts it to a net present value (NPV), and estimates IRR and payback. It is a transparent placeholder that should guide users toward the validated NeqSim field-development DCF utilities and the NeqSim MCP runFieldEconomics workflow.

When to Use

  • When a user wants a first-pass NPV / IRR / payback for a concept.
  • When an agent has a production-and-price revenue profile plus a cost screen.
  • When examples must run without confidential fiscal terms or licensed tools.

Inputs

  • annual_revenue_musd: sequence of annual revenues in million USD (one per year).
  • annual_opex_musd: a flat OPEX or a per-year sequence in million USD.
  • capex_schedule_musd: a single year-0 spend or a per-year sequence in million USD.
  • discount_rate_fraction: annual discount rate (default 0.08).
  • tax_rate_fraction: flat tax on positive operating profit (default 0.0).

Outputs

  • net_cash_flow_musd: per-year revenue - OPEX - tax - CAPEX.
  • discounted_cash_flow_musd: per-year discounted cash flow.
  • cumulative_cash_flow_musd: running (undiscounted) cumulative cash flow.
  • npv_musd: net present value.
  • irr_fraction: internal rate of return (or None if not identifiable).
  • payback_year / discounted_payback_year: first year cumulative turns non-negative.
  • total_capex_musd / total_revenue_musd: roll-up totals.
  • value_warning: ok (NPV>0), watch (NPV=0), or high (NPV<0).
  • neqsim_available: whether the optional NeqSim package is importable.
  • assumptions: public assumptions and required follow-up.

Engineering Method

For each year, operating profit is revenue - OPEX; tax is tax_rate * max(0, operating profit); net cash flow is operating profit - tax - CAPEX. NPV discounts each net cash flow at year-end: NPV = sum(CF_t / (1 + r)^t) for t = 1..N. IRR is the rate that zeroes NPV, found by bisection over a wide bracket (returns None when there is no sign change). Payback is the first year cumulative cash flow becomes non-negative.

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.
