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 | $0.00089 | $0.01298 |
| Opus 5 | $0.00044 | $0.00649 |
| Sonnet 5 | $0.00018 | $0.00260 |
| Haiku 4.5 | $0.00009 | $0.00130 |
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 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.

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 (orNoneif 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), orhigh(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.
What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

neqsim-asset-value-npv-screening is a skill published in the GitHub repository equinor/neqsim-community-skills (2 stars, last pushed today), licensed Apache-2.0. It adds 89 tokens to every session and 1,298 once invoked, about $0.0004 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.
