## What it does

The skill walks through token-based sessions in JavaScript. It shows how to sign an access token and a refresh token with `jsonwebtoken`, a `SessionStore` class on top of the `redis` client with methods to create a session and wipe every session for a user, cookie settings with `httpOnly`, `secure` and `sameSite`, and a `POST /auth/refresh` handler that checks the token type before issuing a new pair.

A separate section lists the security rules: HTTPS only, `httpOnly` and `sameSite` on cookies, bounded token lifetimes, a distinct secret per environment, signature validation on every request. Then the anti-patterns — no sensitive data inside a token, no tokens in URL parameters, no weak or shared secrets, no skipping signature checks.

The examples read `JWT_SECRET`, `REFRESH_SECRET` and `SESSION_SECRET` from the environment. Leave those unset and nothing runs, so check your config before this code goes anywhere near production. What you get is reference code to paste into your own project and adapt, not a drop-in library.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill session-management -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/session-management/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/session-management/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill session-management -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/session-management/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill session-management -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/session-management/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install secondsky/claude-skills session-management
```

2. **Manually: put the files in place**
- File: `.github/skills/session-management/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill session-management -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/secondsky/claude-skills --path plugins/session-management/skills/session-management
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/session-management/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add secondsky/claude-skills --skill session-management -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/secondsky/claude-skills/tree/HEAD/plugins/session-management/skills/session-management/SKILL.md

## When to use it
- issue an access and refresh token pair for a user
- keep active sessions in Redis and revoke them all at once
- configure cookies with httpOnly, secure and sameSite
- build a refresh endpoint that validates the token type
- close common holes like passing tokens in URL parameters

## Example prompts
- add JWT login to this project: one-hour access token, seven-day refresh token
- store sessions in Redis with a method that clears all sessions for a user
- review my session cookie settings: httpOnly, secure, sameSite

# Session Management

Implement secure session management with proper token handling and storage.

## Token-Based Sessions

```javascript
const jwt = require('jsonwebtoken');

function generateTokens(user) {
  const accessToken = jwt.sign(
    { userId: user.id, role: user.role, type: 'access' },
    process.env.JWT_SECRET,
    { expiresIn: '1h' }
  );

  const refreshToken = jwt.sign(
    { userId: user.id, type: 'refresh' },
    process.env.REFRESH_SECRET,
    { expiresIn: '7d' }
  );

  return { accessToken, refreshToken };
}
```

## Redis Session Storage

```javascript
const redis = require('redis');
const client = redis.createClient();

class SessionStore {
  async create(userId, sessionData) {
    const sessionId = crypto.randomUUID();
    await client.hSet(`sessions:${userId}`, sessionId, JSON.stringify({
      ...sessionData,
      createdAt: Date.now()
    }));
    await client.expire(`sessions:${userId}`, 86400 * 7);
    return sessionId;
  }

  async invalidateAll(userId) {
    await client.del(`sessions:${userId}`);
  }
}
```

## Cookie Configuration

```javascript
app.use(session({
  name: 'session',
  secret: process.env.SESSION_SECRET,
  cookie: {
    httpOnly: true,
    secure: process.env.NODE_ENV === 'production',
    sameSite: 'strict',
    maxAge: 3600000, // 1 hour
    domain: '.example.com'
  },
  resave: false,
  saveUninitialized: false
}));
```

## Token Refresh Flow

```javascript
app.post('/auth/refresh', async (req, res) => {
  const { refreshToken } = req.cookies;

  try {
    const payload = jwt.verify(refreshToken, process.env.REFRESH_SECRET);
    if (payload.type !== 'refresh') throw new Error('Invalid token type');

    const user = await User.findById(payload.userId);
    const tokens = generateTokens(user);

    res.cookie('accessToken', tokens.accessToken, cookieOptions);
    res.json({ success: true });
  } catch (err) {
    res.status(401).json({ error: 'Invalid refresh token' });
  }
});
```

## Security Requirements

- Use HTTPS exclusively
- Set httpOnly and sameSite on cookies
- Implement proper token expiration
- Use strong, unique secrets per environment
- Validate signatures on every request

## Never Do

- Store sensitive data in tokens
