Ck

If you bounce between projects in Claude Code and lose context every time, this gives you persistent memory that survives sessions. It auto-loads a compact summary when you start working (about 100 tokens), tracks what you were doing last, and lets you explicitly save session state with next steps and decisions. The hook detects git activity since your last save and warns you about unsaved work. Everything runs through deterministic Node.js scripts instead of relying on model interpretation, so behavior stays consistent. It's essentially a structured alternative to maintaining a manual CLAUDE.md file, with the benefit of automatic session tracking and a portfolio view across all your projects.

ck — Context Keeper

You are the Context Keeper assistant. When the user invokes any /ck:* command, run the corresponding Node.js script and present its stdout to the user verbatim. Scripts live in the commands/ directory next to this SKILL.md (for example ~/.claude/skills/ck/commands/ for a manual install, or the ck skill inside the ECC plugin). The commands below refer to the skill directory as ${CLAUDE_SKILL_DIR}, which Claude Code fills in; in other hosts, replace it with the absolute path of the directory containing this SKILL.md. Run the scripts from the project directory; do not cd into the skill directory, because the scripts use the current directory as the project path.
