Individual skill

pho-audit-solver

Solve Public Health Observatory algorithmic transportability audits using an HTTP portal API. Covers release resolution, cohort construction, and a catalog of reusable statistical modules (fixed-effects jackknife, ridge/elastic-net CV, wild cluster bootstrap, grouped conformal, PCA clustering, source perturbation, GMM mediation, and sensitivity surfaces) with exact output formatting against a provided answer template.

# PHO Audit Solver

This skill equips you to solve Public Health Observatory (PHO) algorithmic audit tasks. Every task follows the same core pattern: read a prompt plus `analysis_request.json` and `answer_template.json`, gather evidence from the PHO web portal, run the declared statistical modules, and return one JSON object conforming to the template.

**What this skill covers**

- Navigating the PHO portal API to pull publication records
- Resolving final releases with revision and timestamp precedence
- Building analytic cohorts (complete, balanced, broad, dual-source, machine-learning)
- Implementing every statistical module that appears across the PHO audit family: fixed-effects OLS with jackknife inference, ridge and elastic-net nested cross-validation, PCG32/xorshift wild cluster bootstrap, grouped split conformal calibration, covariance PCA with farthest-first k-means, exhaustive source/time perturbation with Shapley attribution, difference GMM mediation, and partial-R2 sensitivity surfaces
- Formatting output exactly to an answer template, applying controlled decision rules
