Context Kit is an external project that organizes personal context into Markdown artifacts and companion Claude Code skills. This skill helps the user decide what to adopt, where to store it, and how to avoid turning a useful context system into a pile of sensitive data.
Treat every personal context file as private by default. These files may contain identity details, family context, work history, contact notes, mental models, health constraints, or relationship information. Do not paste them into third-party tools, public repositories, issue trackers, or model contexts unless the user explicitly approves the exact subset.

Before running an installer, verify:
If anything is unclear, stop at inspection and provide the user with the exact lines that need review.
bashgit clone https://github.com/JDDavenport/context-kit.git cd context-kit sed -n '1,220p' scripts/install.sh find templates skills -maxdepth 2 -type f | sort
After inspection, summarize the files that would be installed and ask for confirmation before running the installer.
bashmkdir -p .agent/context printf '.agent/context/\n' >> .gitignore cp ~/Downloads/context-kit/templates/pca-wiki.md .agent/context/pca-wiki.md
Then trim the template to the minimum useful fields for the project instead of filling every personal section immediately.

DecimalAI ran this skill against gemini-3.6-flash twice over the same eval suite — once with the skill loaded and once without — and compared the two runs case by case. 22 cases were attempted. The headline lift of +36 percentage points is the difference between those two pass rates over the 22 comparable cases.
Without the skill loaded, the model failed this case. With it loaded, the same prompt on the same model passed. This is one improved case from the latest verified run; every case, including any that regressed, is in the table above.
Other measured skills in the registry, with their headline benchmark lift.
