Asks which skills and agents to install. Just one: npx skills add amkessler/nicar2026_skills_in_codex_claude --skill fecfile — add -g for every project.
Claude Code
git clone https://github.com/amkessler/nicar2026_skills_in_codex_claudecp -r "nicar2026_skills_in_codex_claude/skills/fecfile" ~/.claude/skills/
Copies the fecfile skill into ~/.claude/skills/ for every project (use .claude/skills/ for one project). Repeat for the other skills listed below.
Plugin
/plugin marketplace add amkessler/nicar2026_skills_in_codex_claude
Run inside Claude Code if the repository ships a plugin marketplace, then pick plugins from /plugin.
Skills can run code on your machine — read the SKILL.md first.
What it does
In the author's own words, from each skill's SKILL.md.
-
fecfile
Analyze FEC (Federal Election Commission) campaign finance filings. Use when working with FEC filing IDs, campaign finance data, contributions, disbursements, or political committee financial reports.

image-rotator
This skill should be used when users need to rotate images by 90 degrees. It handles image rotation tasks for common formats (PNG, JPG, JPEG, GIF, BMP, TIFF) using a reliable Python script that preserves image quality and supports both clockwise and counter-clockwise rotation.

majority-minority-change
This skill should be used when users need to analyze county-level racial composition change between two Census snapshots and identify where places crossed a majority-minority threshold.
skills/majority-minority-change/SKILL.md on GitHub (opens in a new tab) -
skill-creator
Guide for creating effective skills. This skill should be used when users want to create a new skill or update an existing skill that extends Claude Code, Codex, or another agent with specialized knowledge, workflows, or tool integrations.
skills/skill-creator/SKILL.md on GitHub (opens in a new tab) -
state-county-rankings
This skill should be used when users need ranked county-level demographic metrics within a state from a local CSV file, such as income, population, poverty, or rent.
skills/state-county-rankings/SKILL.md on GitHub (opens in a new tab) -
weather-forecast
Fetch 7-day weather forecasts from Open-Meteo API. ALWAYS use get_coordinates.py first when given city names to look up coordinates, then use get_forecast.py with those coordinates. Use for weather forecasts, weather data, or temperature trends.
skills/weather-forecast/SKILL.md on GitHub (opens in a new tab)

Review before you install
A skill is a set of instructions and scripts your agent will follow, and it can run code on your machine. Read the SKILL.md and any scripts first — this listing is not a security review.
