Secrets

Each stack has its own .env file:

~/.prompt-stack/stacks/<stack>/.env

When you install a stack, a .env is created with placeholders. Add your keys:

# ~/.prompt-stack/stacks/postgres/.env
DATABASE_URL=postgresql://user:pass@host:5432/db

Secrets are automatically injected into Claude, Codex, and Gemini configs.

How It Works

1. pstack install stack:slack downloads the MCP server
2. Creates .env with required secrets as placeholders
3. Registers the MCP server in ~/.claude/settings.json, ~/.codex/config.toml, ~/.gemini/settings.json
4. You fill in the API key in .env
5. Claude/Codex/Gemini can now use the tools
