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 5,553 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 projectIn 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 projectsStandalone 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 projectsSource (checked Oct 7, 2026): code.claude.com/docs/en/skills (opens in a new tab), support.claude.com/en/articles/12512180-using-skills-in-claude (opens in a new tab), learn.chatgpt.com/docs/build-skills (opens in a new tab), cursor.com/docs/context/skills (opens in a new tab)
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.
