description	Educational economy-basis assembly and range-check screening for prices, discount rate, currency, inflation, and tax regime. USE WHEN: a task needs a public, screening-level economic assumptions basis with sanity flags before an asset-value (NPV) screening or detailed NeqSim field-economics modelling.

Economy Basis Screening

Use this skill to assemble and sanity-check the economic assumptions that feed a downstream asset-value (NPV) screening: gas and oil prices, discount rate, currency, inflation, and tax regime. It echoes a normalized basis, range-checks the discount rate against an indicative public band, checks the tax regime against a small public name set, and raises consistency flags. It is intentionally simple and should guide users toward the validated NeqSim field-economics workflow and the NeqSim MCP runFieldEconomics tool.

When to Use

• When a user needs a clean, documented economic-assumptions basis before NPV work.
• When an early concept needs a discount-rate and tax-regime sanity check.
• When an agent needs an upstream "economy basis" feed for an asset-value screening chain.

Inputs

• gas_price_per_sm3: gas price in the chosen currency per Sm3.
• oil_price_per_bbl: oil price in the chosen currency per barrel.
• discount_rate: real or nominal discount rate (fraction, 0-1).
• currency: currency code (default USD).
• inflation_rate: inflation rate (fraction, default 0).
• real_terms: whether the basis is in real terms (default True).
• tax_regime: tax-regime label (generic, norwegian-ncs, uk, us, none).

Outputs

• currency, gas_price_per_sm3, oil_price_per_bbl, discount_rate, real_terms, inflation_rate, tax_regime.
• discount_rate_flag: ok, low, or high vs the indicative band.
• tax_regime_recognized: whether the regime is in the public name set.
• basis_warning: ok or watch.
• flags: human-readable consistency warnings.
• neqsim_available: whether the optional NeqSim package is importable.
• assumptions: public assumptions and required follow-up.

Engineering Method

The skill normalizes the supplied assumptions and applies transparent checks: the discount rate is compared against an indicative public band (default 6%-12%); the tax regime is checked against a small public name set; and consistency flags are raised for zero-revenue, or nominal terms with zero inflation. The verdict is watch when any flag is raised, otherwise ok.

This skill performs no fiscal, financing, currency-forward, or escalation modelling. It is a transparent placeholder that must be replaced by a validated NeqSim field-economics workflow for any quantitative use.

Python Usage Pattern

from economy_basis_screening import EconomyBasisModel

model = EconomyBasisModel()
result = model.evaluate(
    gas_price_per_sm3=0.30,
    oil_price_per_bbl=70.0,
    discount_rate=0.08,
    currency="USD",
    tax_regime="norwegian-ncs",
)

print(result.discount_rate_flag, result.tax_regime_recognized)
print(result.basis_warning)
for flag in result.flags:
    print(flag)

Validated NeqSim Path

This screening is a placeholder. For real economic evaluation use:

• neqsim.process.util.fielddevelopment discounted cash-flow and field-economics calculators (NPV, IRR, payback) with tax-regime support.
• The NeqSim MCP runFieldEconomics tool for an orchestrated economic evaluation.
• The community asset-value-npv-screening skill for a screening NPV from a net cash-flow profile that uses this economy basis.

Escalation

Escalate any watch verdict, and any quantitative use, to a validated NeqSim field-economics workflow and qualified commercial review.

Validation Checklist

• Inputs are validated and within stated ranges.
• Examples use public data only.
• Screening assumptions are stated explicitly.
• Limitations are respected.
• Quantitative use is escalated to validated NeqSim models.

Common Mistakes

Symptom	Cause	Fix
Unrealistic result	Inputs outside the screening range	Keep inputs within the stated bounds
Misused for design	Screening output taken as final	Escalate to validated NeqSim models

Limitations

• Educational screening only; not a validated design method.
• No confidential data or proprietary methods are included.
• Escalate any quantitative or design use to validated NeqSim workflows.
