## What it does

The hook monitors GitHub Copilot coding agent lifecycles by intercepting session launches, terminations, and prompt submissions. It stores structured JSON records directly on disk. Session milestones go to `logs/copilot/session.log`, while prompt inputs land in `logs/copilot/prompts.log`.

Three bash scripts handle the automation: `log-session-start.sh`, `log-session-end.sh`, and `log-prompt.sh`. Each operation runs with a 5-second timeout. The logger records timestamps alongside the current working directory. You can adjust verbosity with `LOG_LEVEL` or halt data collection entirely by setting `SKIP_LOGGING=true`.

Add `logs/` to `.gitignore` immediately to prevent sensitive prompt logs from leaking into remote branches. The shell scripts also fail silently if they lack execution permissions via `chmod +x`.

## Install

### Claude Code (native platform)

**Manually: put the files in place**
- File: `.claude/settings.json` — The hooks block: event (PreToolUse, PostToolUse, Stop…) → command. Personal ones go to ~/.claude/settings.json

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/github/awesome-copilot/tree/HEAD/hooks/session-logger

## When to use it
- Audit coding agent activity on local machines
- Record session start and termination timestamps
- Store submitted developer prompts in structured JSON
- Disable event capturing during private work using `SKIP_LOGGING=true`

## Example prompts
- Refactor the authentication logic in `auth.ts`
- Run the unit test suite and fix failing tests
- Generate database migration scripts for the user table

# Session Logger Hook

Comprehensive logging for GitHub Copilot coding agent sessions, tracking session starts, ends, and user prompts for audit trails and usage analytics.

## Overview

This hook provides detailed logging of Copilot coding agent activity:
- Session start/end times with working directory context
- User prompt submission events
- Configurable log levels

## Features

- **Session Tracking**: Log session start and end events
- **Prompt Logging**: Record when user prompts are submitted
- **Structured Logging**: JSON format for easy parsing
- **Privacy Aware**: Configurable to disable logging entirely

## Installation

1. Copy this hook folder to your repository's `.github/hooks/` directory:
   ```bash
   cp -r hooks/session-logger .github/hooks/
   ```

2. Create the logs directory:
   ```bash
   mkdir -p logs/copilot
   ```

3. Ensure scripts are executable:
   ```bash
   chmod +x .github/hooks/session-logger/*.sh
   ```

4. Commit the hook configuration to your repository's default branch

## Log Format

Session events are written to `logs/copilot/session.log` and prompt events to `logs/copilot/prompts.log` in JSON format:

```json
{"timestamp":"2024-01-15T10:30:00Z","event":"sessionStart","cwd":"/workspace/project"}
{"timestamp":"2024-01-15T10:35:00Z","event":"sessionEnd"}
```

## Privacy & Security

- Add `logs/` to `.gitignore` to avoid committing session data
- Use `LOG_LEVEL=ERROR` to only log errors
- Set `SKIP_LOGGING=true` environment variable to disable
- Logs are stored locally only
