did skillA

did is agent-read markdown (skill) from ericluo04/claude-academic-workflow: Design, estimate, validate, and write up a difference-in-differences analysis, using the post-2018 heterogeneity-robust toolkit with an explicit statement of which parallel-trends assumption is imposed. TRIGGER on "difference-in-differences", "DiD", "TWFE", "event study", "staggered adoption", "parallel trends", "pre-trends", "Callaway-Sant'Anna", "HonestDiD", "triple differences", "Poisson DiD", "nonlinear DiD", or any panel or repeated-cross-section setting where units become treated over time.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
