Burn After Login — Development skill for Claude Code

burn-after-login

*"Good morning. Your mission, should you choose to accept it, is to create dev-only auth shortcuts so AI browser agents stop fumbling with your login forms. This skill will self-destruct after completion."*

A self-destructing [Agent Skill](https://agentskills.io) that creates dev-only auth shortcuts for AI browser automation — then removes itself, leaving no trace.

The Problem

AI agents with browser automation (Claude in Chrome, Playwright MCP, agent-browser, Stagehand, Cursor's browser mode...) hit login walls and waste time filling out forms, handling redirects, and losing session state.

The Solution

Install the skill, run it, and it sets up dev-only auth shortcuts tailored to your stack. After setup, your agents can authenticate in one step:

# Browser agents navigate here to get authenticated
http://localhost:3000/dev-login?email=demo@test.com&password=demo

# Or grab a token for API testing
TOKEN=$(./scripts/get-token demo@test.com demo)

How It Works

1. Install the skill
2. Run it — it analyzes your auth system and creates dev-only shortcuts
3. It detects your browser automation tools and updates agent instructions
4. It asks to self-destruct
5. You're left with working auth shortcuts and zero trace of the skill

Install

npx skills add pbakaus/burn-after-login

This installs the skill into your project's `.agents/skills/` directory (and symlinks into `.claude/skills/` and other tool-specific locations as needed).

Use

In Claude Code:

/burn-after-login

In other [compatible agents](https://agentskills.io), invoke the skill per your tool's conventions.

What It Does

1. Validates your environment has dev mode detection and an auth system
2. Finds existing dev/test credentials in your codebase
3. Analyzes how your auth works (tokens, sessions, or both)
4. Creates dev-only auth shortcuts that match your stack:
   • Login endpoints for session-based auth
   • Tok
