# project-selector
|
||||||
|
|
||||||
|
FZF-based project selector for Claude Code. Navigate to projects by category, auto-create CLAUDE.md files, link skills from a marketplace, and manage running Claude sessions to prevent CPU overload.
|
||||||
|
|
||||||
|
## Installation
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Add to your .bashrc or .zshrc
|
||||||
|
source /path/to/project-selector/cw.sh
|
||||||
|
```
|
||||||
|
|
||||||
|
## Usage
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cw # Launch project selector
|
||||||
|
cw --resume # Launch with args passed to claude
|
||||||
|
```
|
||||||
|
|
||||||
|
## Features
|
||||||
|
|
||||||
|
### Category-Based Navigation
|
||||||
|
|
||||||
|
Select from organized project categories:
|
||||||
|
|
||||||
|
| Category | Paths |
|
||||||
|
|----------|-------|
|
||||||
|
| Sales | `/opt/clients/client-upfrontops/*` |
|
||||||
|
| Admin | `/opt/personal/*`, `/opt/docker-vpn` |
|
||||||
|
| Fun | `/opt/fun/*` |
|
||||||
|
| Pre-Revenue | `/opt/pre-revenue/*` |
|
||||||
|
| Clients | `/opt/clients/*` |
|
||||||
|
| Personal | `/opt/personal/*` |
|
||||||
|
| Infrastructure | `/opt/infra/*`, `/opt/docker-vpn`, `/opt/marketplace`, `/opt/tools` |
|
||||||
|
| All Repos | Scans all `.git` directories under `/opt` |
|
||||||
|
| Manual Selection | Drill down from `/opt` |
|
||||||
|
|
||||||
|
### Session Management
|
||||||
|
|
||||||
|
Prevents CPU overload from too many concurrent Claude instances:
|
||||||
|
|
||||||
|
- **Info Display**: Shows running Claude sessions at startup (load <60%, <4 sessions)
|
||||||
|
- **Hard Block**: Must kill a session to proceed (load >=60% OR >=4 sessions)
|
||||||
|
- **Orphan Detection**: Flags sessions with no controlling terminal as `(ORPHAN)`
|
||||||
|
- **Graceful Termination**: SIGTERM with 5-second wait, then SIGKILL if needed
|
||||||
|
|
||||||
|
```
|
||||||
|
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
||||||
|
Load: 34% (5-min avg) | Sessions: 2 running
|
||||||
|
/opt/clients/acme-corp (2h 15m, 47% CPU)
|
||||||
|
/opt/pre-revenue/newapp (45m, 23% CPU)
|
||||||
|
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
||||||
|
```
|
||||||
|
|
||||||
|
### CLAUDE.md Scaffolding
|
||||||
|
|
||||||
|
When navigating to a directory without a CLAUDE.md file:
|
||||||
|
|
||||||
|
1. Prompts to create one
|
||||||
|
2. Asks for project description
|
||||||
|
3. Asks for common commands
|
||||||
|
4. Generates structured CLAUDE.md
|
||||||
|
|
||||||
|
### Skill Linking
|
||||||
|
|
||||||
|
Links skills from `/opt/marketplace/skills/` to projects:
|
||||||
|
|
||||||
|
1. Multi-select skills with fzf (Tab to toggle)
|
||||||
|
2. Creates `.claude/skills/` directory
|
||||||
|
3. Symlinks selected skills
|
||||||
|
|
||||||
|
### Git Integration
|
||||||
|
|
||||||
|
- Auto-detects git repos (stops drill-down at `.git`)
|
||||||
|
- Prompts to initialize git for non-repo directories
|
||||||
|
- Shows parent repo context when in subdirectory
|
||||||
|
|
||||||
|
## Navigation Controls
|
||||||
|
|
||||||
|
| Action | Key |
|
||||||
|
|--------|-----|
|
||||||
|
| Select | Enter |
|
||||||
|
| Cancel | Esc |
|
||||||
|
| Go back | Select `[GO BACK]` |
|
||||||
|
| Change category | Select `[CHANGE CATEGORY]` |
|
||||||
|
| Start here | Select `[START HERE]` |
|
||||||
|
| Create folder | Select `[NEW FOLDER]` |
|
||||||
|
| Multi-select (skills) | Tab |
|
||||||
|
|
||||||
|
## Dependencies
|
||||||
|
|
||||||
|
- `fzf` - Fuzzy finder for selection UI
|
||||||
|
- `claude` - Claude Code CLI (auto-detects `~/.local/bin/claude` for native installer)
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
Categories and paths are defined in `cw.sh`. Edit the case statement in the `cw()` function to customize.
|
||||||
|
|
||||||
|
## Session Management Thresholds
|
||||||
|
|
||||||
|
| Condition | Behavior |
|
||||||
|
|-----------|----------|
|
||||||
|
| Load <60% AND sessions <4 | Show info, continue |
|
||||||
|
| Load >=60% OR sessions >=4 | Must kill a session |
|
||||||
|
|
||||||
|
Load is calculated as 5-minute load average divided by CPU count.
|
||||||
|

# Claude Session Manager for `cw`
|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
Add a pre-flight check at the start of `cw` that monitors running Claude sessions and enforces a tiered response based on system load and session count. Prevents CPU overload from too many concurrent Claude instances and helps identify/clean orphaned processes.
|
||||||
|
|
||||||
|
## Problem Statement
|
||||||
|
|
||||||
|
- Multiple Claude instances running simultaneously cause sustained 100% CPU
|
||||||
|
- User intentionally multitasks across projects but loses track of session count
|
||||||
|
- Orphaned Claude processes (from closed terminals) pile up and waste resources
|
||||||
|
|
||||||
|
## Tiered Logic
|
||||||
|
|
||||||
|
```
|
||||||
|
┌─────────────────────────────────────────────────────────────┐
|
||||||
|
│ cw() starts │
|
||||||
|
└─────────────────────────────────────────────────────────────┘
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
┌─────────────────────────────────────────────────────────────┐
|
||||||
|
│ Count running Claude processes + get their details │
|
||||||
|
│ Get system 5-min load average │
|
||||||
|
└─────────────────────────────────────────────────────────────┘
|
||||||
|
│
|
||||||
|
▼
|
||||||
|
┌─────────────────────┐
|
||||||
|
│ Sessions >= 4 OR │
|
||||||
|
│ Load avg >= 60%? │
|
||||||
|
└─────────┬───────────┘
|
||||||
|
yes │ no
|
||||||
|
┌───────────────┴───────────────┐
|
||||||
|
▼ ▼
|
||||||
|
┌──────────────────┐ ┌─────────────────┐
|
||||||
|
│ HARD BLOCK │ │ INFO ONLY │
|
||||||
|
│ Must kill one │ │ Show sessions │
|
||||||
|
│ to proceed │ │ (if any) │
|
||||||
|
└──────────────────┘ │ Continue auto │
|
||||||
|
└─────────────────┘
|
||||||
|
```
|
||||||
|
|
||||||
|
### Rules Summary
|
||||||
|
|
||||||
|
| Condition | Behavior |
|
||||||
|
|-----------|----------|
|
||||||
|
| Load < 60% AND sessions < 4 | Show running sessions as FYI, continue to category menu |
|
||||||
|
| Load >= 60% OR sessions >= 4 | Hard block - must kill a session to proceed |
|
||||||
|
|
||||||
|
## Session Display Format
|
||||||
|
|
||||||
|
Each session shown as:
|
||||||
|
```
|
||||||
|
/opt/clients/acme-corp (2h 15m, 47% CPU)
|
||||||
|
/opt/infra/project-selector (ORPHAN) (45m, 12% CPU)
|
||||||
|
```
|
||||||
|
|
||||||
|
Orphans flagged with `(ORPHAN)` tag so user knows they're safe to kill.
|
||||||
|
|
||||||
|
## Implementation Details
|
||||||
|
|
||||||
|
### Detecting Claude Sessions
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Get Claude processes with: PID, CPU%, elapsed time, controlling TTY, working directory
|
||||||
|
ps -eo pid,pcpu,etime,tty,args | grep -E "^[0-9].*claude$" | grep -v grep
|
||||||
|
```
|
||||||
|
|
||||||
|
For each PID, get the working directory via:
|
||||||
|
```bash
|
||||||
|
readlink -f /proc/<PID>/cwd
|
||||||
|
```
|
||||||
|
|
||||||
|
### Detecting Orphans
|
||||||
|
|
||||||
|
A Claude process is orphaned if:
|
||||||
|
- Its controlling TTY is `?` (no terminal attached), OR
|
||||||
|
- Its parent PID is 1 (adopted by init)
|
||||||
|
|
||||||
|
Check parent PID via:
|
||||||
|
```bash
|
||||||
|
ps -o ppid= -p <PID>
|
||||||
|
```
|
||||||
|
|
||||||
|
### Load Average
|
||||||
|
|
||||||
|
Use the 5-minute load average from `/proc/loadavg`, normalized to CPU count:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
load=$(awk '{print $2}' /proc/loadavg)
|
||||||
|
cpus=$(nproc)
|
||||||
|
percent=$(awk "BEGIN {printf \"%.0f\", ($load / $cpus) * 100}")
|
||||||
|
```
|
||||||
|
|
||||||
|
### Kill Flow
|
||||||
|
|
||||||
|
1. User selects session from fzf menu
|
||||||
|
2. Send `SIGTERM` to PID
|
||||||
|
3. Wait up to 5 seconds, checking if process died
|
||||||
|
4. If still alive, send `SIGKILL`
|
||||||
|
5. Confirm death, refresh session list
|
||||||
|
|

## User Experience Flow
|
||||||
|
|
||||||
|
### Hard Block Scenario (>=4 sessions OR >=60% load)
|
||||||
|
|
||||||
|
```
|
||||||
|
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
||||||
|
⚠️ Cannot start new Claude session
|
||||||
|
Load: 73% (5-min avg) | Sessions: 4 running
|
||||||
|
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
||||||
|
|
||||||
|
Select a session to kill (or Esc to cancel):
|
||||||
|
|
||||||
|
> /opt/clients/acme-corp (2h 15m, 47% CPU)
|
||||||
|
/opt/pre-revenue/newapp (45m, 23% CPU)
|
||||||
|
/opt/infra/project-selector (ORPHAN) (1h 02m, 3% CPU)
|
||||||
|
/opt/fun/gamedev (12m, 18% CPU)
|
||||||
|
```
|
||||||
|
|
||||||
|
After selection:
|
||||||
|
```
|
||||||
|
Stopping /opt/clients/acme-corp (PID 10764)...
|
||||||
|
Terminated gracefully.
|
||||||
|
|
||||||
|
Proceeding to project selection...
|
||||||
|
```
|
||||||
|
|
||||||
|
### Info Only Scenario (<4 sessions AND <60% load)
|
||||||
|
|
||||||
|
```
|
||||||
|
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
||||||
|
📊 Load: 34% (5-min avg) | Sessions: 2 running
|
||||||
|
• /opt/clients/acme-corp (2h 15m, 47% CPU)
|
||||||
|
• /opt/pre-revenue/newapp (45m, 23% CPU)
|
||||||
|
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
|
||||||
|
```
|
||||||
|
|
||||||
|
Then immediately shows the category menu (no user action needed).
|
||||||
|
|
||||||
|
### No Sessions Running
|
||||||
|
|
||||||
|
Skip the status display entirely, go straight to category menu.

## Code Structure
|
||||||
|
|
||||||
|
### New Helper Functions
|
||||||
|
|
||||||
|
| Function | Purpose |
|
||||||
|
|----------|---------|
|
||||||
|
| `_cw_get_claude_sessions` | Returns array of running Claude PIDs with metadata |
|
||||||
|
| `_cw_format_session` | Formats a session for display (dir, runtime, CPU%, orphan tag) |
|
||||||
|
| `_cw_get_load_percent` | Returns 5-min load avg as percentage of CPU capacity |
|
||||||
|
| `_cw_kill_session` | Graceful kill with SIGTERM→wait→SIGKILL fallback |
|
||||||
|
| `_cw_session_check` | Main orchestrator: gathers data, decides tier, shows UI |
|
||||||
|
|
||||||
|
### Integration Point
|
||||||
|
|
||||||
|
At the very top of `cw()`, after dependency checks:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
cw() {
|
||||||
|
# Dependency checks (existing)
|
||||||
|
...
|
||||||
|
|
||||||
|
# NEW: Session/load check
|
||||||
|
_cw_session_check || return 0
|
||||||
|
|
||||||
|
# Rest of existing code
|
||||||
|
...
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
`_cw_session_check` returns:
|
||||||
|
- `0` (success) - proceed with `cw`
|
||||||
|
- `1` (failure) - user cancelled at hard block, exit `cw`
|
||||||
|
|
||||||
|
### File Changes
|
||||||
|
|
||||||
|
Only `cw.sh` needs modification - all new functions added to the same file.
