Claude Session Tracker (CST)

A Claude Code plugin that tracks your sessions and provides an interactive TUI launcher to browse and resume previous sessions.

Features

• Session tracking via Claude Code lifecycle hooks (SessionStart, UserPromptSubmit, SessionEnd)
• Prompt history - stores the last 10 user prompts per session for context
• Interactive TUI with search, preview pane, and keyboard navigation
• Active session detection - identifies and filters currently-running sessions
• Cross-platform - pure Go binary, no CGO required
• Concurrent-safe - SQLite WAL mode handles multiple simultaneous Claude sessions

Installation

1. Install the binary

From releases:

# Linux (amd64)
curl -L https://github.com/imyousuf/claude-session-tracker/releases/download/dev/cst-linux-amd64.tar.gz | tar xz
mv cst ~/.local/bin/

# macOS (Apple Silicon)
curl -L https://github.com/imyousuf/claude-session-tracker/releases/download/dev/cst-darwin-arm64.tar.gz | tar xz
mv cst ~/.local/bin/

From source:

git clone https://github.com/imyousuf/claude-session-tracker.git
cd claude-session-tracker
make install  # installs to $GOPATH/bin

2. Enable the plugin

Clone the repo (if not done already) and enable it in Claude Code:

git clone https://github.com/imyousuf/claude-session-tracker.git ~/projects/claude-session-tracker

Then in Claude Code, use /plugin to add and enable session-tracker.

Usage

TUI Launcher

cst                          # Sessions for current project
cst --all                    # All sessions across all projects
cst --project /path/to/proj  # Sessions for a specific project

Key bindings:

Key	Action
j/k or ↑/↓	Navigate sessions
Enter	Resume selected session
Tab	Toggle current project / all projects
/	Search/filter sessions
d	Delete session entry
q / Esc	Quit

Non-Interactive List

cst list                     # Table output
cst list --all --json        # JSON output for scripting

Maintenance

cst cleanup                  # Remove inactive sessions older than 30 days
cst cleanup --days 7         # Custom age threshold
cst version                  # Show version info

How It Works

CST uses three Claude Code lifecycle hooks:

1. SessionStart - Records the session as active with its project path, model, and PID
2. UserPromptSubmit - Captures the user's prompt (skipping slash commands) and updates activity timestamp
3. SessionEnd - Marks the session as inactive

Session data is stored in ~/.cst/sessions.db (SQLite with WAL mode).

When launching the TUI, CST validates active sessions by checking if their PIDs are still alive, automatically cleaning up stale entries from crashed sessions.

Architecture

cmd/cst/          CLI entry point (cobra)
internal/
  store/          SQLite session store (modernc.org/sqlite, pure Go)
  hook/           Hook event handlers (read stdin JSON, update store)
  launcher/       Bubbletea TUI (session list + preview pane)
  procutil/       Cross-platform process liveness checking

Development

make build       # Build to bin/cst
make test        # Run tests with race detector
make test-fast   # Run tests without race detector
make fmt         # Format code
make lint        # Run golangci-lint
make install     # Build and install to $GOPATH/bin
