Context Engineering

Context Engineering is an agent skill (a SKILL.md file) from mvschwarz/openrig. Agents load it when designing, reviewing, or debugging how an agent's context window gets filled, pruned, or shared — choosing what loads at boot versus on demand, sizing… It works with Claude Code and Codex and has 8,198 GitHub stars across a repository of 4 listed skills.

Add this skill

Claude

Claude Code loads skills from ~/.claude/skills/ (all projects) or .claude/skills/ (one project):

git clone --depth 1 https://github.com/mvschwarz/openrig.git
cp -r openrig/skills/_canonical/process/context-engineering ~/.claude/skills/context-engineering   # personal, or .claude/skills in a project

In the Claude apps, zip the context-engineering folder and upload it under Customize > Skills > + > Upload a skill (code execution must be on).

ChatGPT / Codex

Codex reads skills from .agents/skills/ in a repo or ~/.agents/skills/ for every project:

git clone --depth 1 https://github.com/mvschwarz/openrig.git
cp -r openrig/skills/_canonical/process/context-engineering .agents/skills/context-engineering   # repo; ~/.agents/skills for all projects

Standalone skills also load in the ChatGPT desktop app.

Cursor

Cursor loads skills from .cursor/skills/ (or ~/.cursor/skills/) and also reads .claude/skills/:

git clone --depth 1 https://github.com/mvschwarz/openrig.git
cp -r openrig/skills/_canonical/process/context-engineering .cursor/skills/context-engineering   # project; ~/.cursor/skills for all projects

What this skill does

Use when designing, reviewing, or debugging how an agent's context window gets filled, pruned, or shared — choosing what loads at boot versus on demand, sizing an install or an always-loaded file, fixing an agent that drifts, repeats itself, or forgets constraints mid-task, planning compaction or summarization, deciding single-agent versus subagents, engineering handoffs between agents, or picking a tool loadout.
