Diagnose and fix slow pyfixest regression GRIDS (many feols/fepois calls run sequentially) that stay slow despite demeaner_backend="cupy64" and an idle GPU. Use when: (1) a script looping dozens of pf.feols models on a 100k+ row panel takes ~1 min/model, (2) process inspection shows ~1-1.5 cores busy and nvidia-smi shows ~0% GPU utilization with a resident cupy context, (3) planning any worker prompt that will run a model grid (robustness variants x FE structures x domains). Root cause: per-mod…

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'pyfixest-grid-sharding' ] || [ -L ~/.agents/skills/'pyfixest-grid-sharding' ]; then echo 'A skill folder named pyfixest-grid-sharding already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/kennethkhoocy/applied-micro-skills' "$d" && git -C "$d" checkout --quiet '28d6f6445e745711fc64a4faeebca35eac1b2b02' -- 'plugins/applied-micro/skills/pyfixest-grid-sharding' && mkdir -p ~/.agents/skills && cp -R "$d"/'plugins/applied-micro/skills/pyfixest-grid-sharding' ~/.agents/skills/'pyfixest-grid-sharding' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'pyfixest-grid-sharding' ~/.claude/skills/'pyfixest-grid-sharding' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
