# 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 at: `~/.claude/skills/ck/commands/` (expand `~` with `$HOME`).

## Data Layout
```
~/.claude/ck/
├── projects.json ← path → {name, contextDir, lastUpdated}
└── contexts/<name>/
├── context.json ← SOURCE OF TRUTH (structured JSON, v2)
└── CONTEXT.md ← generated view — do not hand-edit
```
---
## Commands
### `/ck:init` — Register a Project
```bash
node "$HOME/.claude/skills/ck/commands/init.mjs"
```
The script outputs JSON with auto-detected info. Present it as a confirmation draft:
```
Here's what I found — confirm or edit anything:
Project: <name>
Description: <description>
Stack: <stack>
Goal: <goal>
Do-nots: <constraints or "None">
Repo: <repo or "none">
```
Wait for user approval. Apply any edits. Then pipe confirmed JSON to save.mjs --init:
```bash
echo '<confirmed-json>' | node "$HOME/.claude/skills/ck/commands/save.mjs" --init
```
Confirmed JSON schema: `{"name":"...","path":"...","description":"...","stack":["..."],"goal":"...","constraints":["..."],"repo":"..." }`

### `/ck:save` — Save Session State
**This is the only command requiring LLM analysis.** Analyze the current conversation:
- `summary`: one sentence, max 10 words, what was accomplished
- `leftOff`: what was actively being worked on (specific file/feature/bug)
- `nextSteps`: ordered array of concrete next steps
- `decisions`: array of `Use this skill
