type:debug

Run a staggered difference-in-differences / event-study analysis to the Sant'Anna practitioner standard — drives the canonical packages (R `did`/`DRDID`/`didFF`/`contdid`; Stata `csdid`/`drdid`), enforces the doubly-robust default, a mandatory diagnostic + sensitivity suite, uniform-band inference, replicate-and-verify-against-source discipline, and ends in a graded credibility verdict. Use when user says "run a DiD", "event study", "staggered adoption", "Callaway Sant'Anna", "att_gt", "csdid", "did with multiple periods", or points at panel data with a treatment-timing variable. NEVER reimplements an estimator.

From the source SKILL.md

This is a thin orchestrator over the canonical packages — it never reimplements an estimator. It walks the practitioner workflow from Difference-in-Differences with Multiple Time Periods (Callaway & Sant'Anna 2021), the Doubly Robust DiD estimators (Sant'Anna & Zhao 2020), and the "What's Trending in DiD?" synthesis (Roth, Sant'Anna, Bilinski & Poe 2023), and it follows the replicate-and-verify-against-source discipline.

What this skill does

Did Event Study is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/did-event-study/ and loads when your prompt matches the skill's trigger.

When to invoke it: Use when user says "run a DiD", "event study", "staggered adoption", "Callaway Sant'Anna", "att_gt", "csdid", "did with multiple periods", or points at panel data with a treatment-timing variable. NEVER reimplements an estimator.
