feat: Claude Code Monitor — lanes, pipelines and a merged workspace

Internal SmartGift build of a Claude Code monitoring dashboard.

Lanes: a durable unit of parallel agent work, one per working directory,
tracked across session restarts. Managed lanes are git worktrees the
dashboard provisions and can reset or remove behind a three-check destroy
guard and a counted preflight; adopted lanes are directories you already
own and are never destroyable.

Pipelines: a lane moves through pipeline stages. A stage the agent declares
with evidence renders green; a stage inferred from the tool-event stream
renders dashed amber and never counts as done. Detection is forward-only
within a 30-minute window, and never writes the declared stage.

Workspace: one page at /run with a lane grid, the selected lane's pipeline,
and a full Claude console behind a disclosure.

# Claude Code Statusline
A color-coded statusline for Claude Code showing model, user, working directory, git branch, context window usage, token counts, and session cost.
## Preview
Example statusline with all segments visible in a git repo and 24% context window usage:
| Segment | Color | Example |
| ----------- | -------------------- | -------------------------------------------------- |
| Model | Cyan | `Sonnet 4.6` |
| User | Green | `nguyens6` |
| CWD | Yellow | `~/agent-dashboard/client` |
| Git branch | Magenta | `main` (hidden outside git repos) |
| Context bar | Green → Yellow → Red | `████████░░ 79%` |
| Tokens | Green / Cyan / Dim | `3↑ 2↓ 156586c` (green `↑` in, cyan `↓` out, dim `c` cache reads) |
| Cost (USD) | Green → Yellow → Red | `$0.4231` (session total — shown on API and subscription plans) |
Context bar color thresholds:
- **Green** — under 50% used
- **Yellow** — 5079% used
- **Red** — 80%+ used
Cost color thresholds:
- **Green** — under $5
- **Yellow** — $5$20
- **Red** — $20+
## Requirements
- Python 3.6+
- Git (for branch detection)
- Claude Code 2.x+
## Installation
**1. Copy both files into your Claude config directory:**
```bash
# macOS / Linux
cp statusline.py ~/.claude/statusline.py
cp statusline-command.sh ~/.claude/statusline-command.sh
chmod +x ~/.claude/statusline-command.sh
# Windows (Git Bash)
cp statusline.py "$HOME/.claude/statusline.py"
cp statusline-command.sh "$HOME/.claude/statusline-command.sh"
```
**2. Update the path in `statusline-command.sh`:**
Open `~/.claude/statusline-command.sh` and replace the path with your own home directory:
```bash
#!/usr/bin/env bash
PYTHONUTF8=1 python3 "/your/home/.claude/statusline.py"
```
On Windows this looks like:
```bash
#!/usr/bin/env bash
PYTHONUTF8=1 python3 "C:/Users/YOUR_USERNAME/.claude/statusline.py"
```
On macOS/Linux:
```bash
#!/usr/bin/env bash
python3 "$HOME/.claude/statusline.py"
```
**3. Add to `~/.claude/settings.json`:**
```json
{
"statusLine": {
"type": "command",
"command": "bash \"/path/to/home/.claude/statusline-command.sh\""
}
}
```
Windows example:
```json
{
"statusLine": {
"type": "command",
"command": "bash \"C:/Users/YOUR_USERNAME/.claude/statusline-command.sh\""
}
}
```
macOS/Linux example:
```json
{
"statusLine": {
"type": "command",
"command": "bash \"/home/YOUR_USERNAME/.claude/statusline-command.sh\""
}
}
```
**4. Restart Claude Code** — fully exit and relaunch. Claude Code does not hot-reload `settings.json`, so the new statusline will not show up until the process is restarted.
## Troubleshooting
**The statusline still shows the default (e.g. `[Model] 📁 cwd`) after restarting.**
Claude Code resolves `statusLine` from multiple settings files, in this precedence (later wins):
1. `~/.claude/settings.json` (user, global)
2. `~/.claude/settings.local.json` (user, local — **often overrides the global**)
3. `<project>/.claude/settings.json` (project, shared)
4. `<project>/.claude/settings.local.json` (project, local)
If any of those later files defines its own `statusLine` block, it **replaces** the global one — yours will never run. Grep for it:
```bash
grep -l statusLine ~/.claude/settings*.json $(find . -maxdepth 3 -name 'settings*.json' -path '*.claude*' 2>/dev/null)
```
For each file that defines a competing `statusLine`, either delete that block (to fall back to the global one) or point it at the same script:
```json
{
"statusLine": {
"type": "command",
"command": "bash \"/path/to/home/.claude/statusline-command.sh\""
}
}
```
**The statusline is blank / missing segments.**
Run the script manually with a sample payload to confirm it works:
```bash
echo '{"model":{"display_name":"Sonnet 4.6"},"workspace":{"current_dir":"'"$HOME"'"},"context_window":{"used_percentage":25,"current_usage":{"input_tokens":1000,"output_tokens":500,"cache_read_input_tokens":200}},"cost":{"total_cost_usd":0.4231}}' \
| sh ~/.claude/statusline-command.sh
```
If nothing prints, check that `python3` is on your `PATH` and `~/.claude/statusline.py` is readable. The script always exits 0 by design so Claude Code never blocks — errors are silent, so test from the shell first.
## How It Works
Claude Code pipes a JSON object to the statusline command's stdin on each update. The script reads that JSON, extracts the relevant fields, and prints a color-coded string using ANSI escape codes.
Key fields used from the JSON payload:
```json
{
"model": { "display_name": "Sonnet 4.6" },
"workspace": { "current_dir": "C:\\Users\\..." },
"context_window": {
"used_percentage": 79,
"current_usage": {
"input_tokens": 3,
"output_tokens": 2,
"cache_read_input_tokens": 156586
}
},
"cost": { "total_cost_usd": 0.4231 }
}
```
## Customization
Edit `statusline.py` directly to change colors, reorder segments, or remove ones you don't want. Each segment is clearly labeled with a comment.
Color constants at the top of the file:
```python
CYAN = '\033[0;36m'
GREEN = '\033[0;32m'
YELLOW = '\033[0;33m'
MAGENTA = '\033[0;35m'
RED = '\033[0;31m'
DIM = '\033[2m'
```
