Load when editing a PolicyEngine country model repo (policyengine-us, policyengine-uk, policyengine-canada) — adding or changing variables, parameters, YAML tests, or contributed reforms. This is the engineering layer (how formulas, parameter YAML, and tests are written), distinct from running analysis. Triggers: add a variable, add a parameter, write a formula, defined_for, adds/subtracts, value_type, definition_period, entity, SPMUnit, TaxUnit, vectorize, where/select, period vs period.this_year, monthly_age, YAML test, absolute_error_margin, contrib reform, in_effect, create_x_reform, neutralize_variable, modify_parameters, changelog.d, StateCode, TANF/SNAP encoding, bracket parameter, -.inf, single_amount. NOT for: household calculations, microsimulation, reform scoring, or distributional analysis (use the policyengine skill); calling the REST API (use policyengine-api).

Put this measurement in your README
A badge carrying how many listings this index holds from the repository and how many pass every static structural check. It reads from this index every time somebody loads your page, so it changes when the measurement changes and there is nothing to keep up to date. Free, no account, and the value is not something you or we can set by hand.
[](https://skillworks.kynth.studio/?q=PolicyEngine%2Fpolicyengine-claude)Would rather not hotlink us? Every badge is also served in shields.io’s endpoint schema, so shields renders the image and your readers never talk to our domain:
Published by Toolproof, the masthead over this index and eight others. The method behind the number is at toolproof.kynth.studio/methodology, and the whole thing is readable as JSON with no key at /api.
