policyengine-calibration-diagnostics
unclassified
Sensitivity registry for PolicyEngine microsim results — maps {program × deviation signature} to the most likely calibration target or imputed variable driving the mismatch. The knowledge base that powers the calibration-diagnostics agent.
Load when investigating why a microsim result differs from a prior score, or when reviewing whether a reform classification is calibration-sensitive.
Triggers: "why does my reform not match", "policyengine cost off", "calibration mismatch", "imputed variable", "takeup rate", "non-filer", "itemizer share", "small state variance", "ECPS calibration target", "policyengine-us-data target", "calibration dashboard", "diagnose mismatch", "deviation signature".

policyengine-prior-scores
unclassified
Structured index of PolicyEngine's previously-published scored reforms. Use this skill to find an anchor for Stage 5 comparison in /analyze-policy, or any time you need a benchmark magnitude for a new policy analysis.
Returns a queryable mapping of {reform name → (cost, poverty, distribution, year, methodology)} drawn from policyengine.org/{us,uk,canada}/research and blog.policyengine.org.
Triggers: "prior PE score", "PolicyEngine has scored", "what did PE find", "PE benchmark", "anchor reform", "comparable reform", "EITC expansion scored", "CTC expansion scored", "SALT cap analysis", "state CTC analysis", "ARPA reform impact", "American Family Act score".

ALWAYS LOAD THIS SKILL before setting up any Python environment or installing packages.
Defines the standard: uv, Python 3.13, uv pip install, .venv at project root.
Triggers: "set up python", "install python", "create a venv", "virtual environment",
"pip install", "install packages", "uv pip", "uv venv", "python version",
"VIRTUAL_ENV", "venv conflict", "which python", "activate", "deactivate",
"run the script", "run with uv", "uv run", "pyproject.toml", "install dependencies",
"install requirements", "install the package", "editable install", "pip install -e",
"latest package", "latest version", "current version", "newest version".

policyengine-microsimulation
ALWAYS USE THIS SKILL for PolicyEngine microsimulation, population-level analysis, winners/losers calculations.
Triggers: microsimulation, share who would lose/gain, policy impact, national average, weighted analysis, cost, revenue impact, budgetary, estimate the cost, federal revenues, tax revenue, budget score, how much would it cost, how much would the policy cost, total cost of, aggregate impact, cost to the government, revenue loss, fiscal impact, poverty impact, child poverty, deep poverty, poverty rate, poverty reduction, how many people lifted out of poverty, SPM poverty, distributional impact, state tax, state-level, California, New York, UBI, universal basic income, flat tax, standard deduction, winners and losers, winners, losers, inequality, Gini, decile, SALT, marginal tax rate, effective tax rate.
NOT for single-household calculations like "what would my benefit be" - use policyengine-us or policyengine-uk for those. Use this skill's code pattern; explore codebase for parameter paths if needed.

management-analysts-131111 ALWAYS LOAD THIS SKILL FIRST before writing PolicyEngine-Canada code or answering household-level Canadian tax/benefit questions.
Covers federal/provincial rules for household calculations. IMPORTANT: no representative population microdata; do NOT attempt microsimulation or population-level estimates. Only household-level analysis.
Triggers: what would, how much would a, benefit be, eligible for, qualify for, single parent, married couple, family of, household of, if they earn, earning $, making $, calculate benefits, calculate taxes, benefit for a, what would I get, maximum, rate, income limit, benefit amount, compare provinces, CCB, Canada Child Benefit, GST credit, HST credit, GST/HST, OAS, GIS, CWB, Canada Workers Benefit, EI, CPP, Ontario Child Benefit, OCB, OTB, BC Climate Action, Alberta Child Benefit, Quebec, CRA, Canadian, Canada, Ontario, British Columbia, Alberta, Saskatchewan, Manitoba, Nova Scotia, New Brunswick, PEI, Newfoundland, Yukon, NWT, Nunavut, provincial tax, federal tax Canada.
