Pi .env Support

Supported Locations

1. ~/.pi/.env - Pi-level config (loaded first)
2. ~/.config/op-ssh/.env.1pass - User-level
3. ./.env.1pass - Project-level (overrides user)

Pi Commands

/op-status

Check 1Password authentication and loaded environment variables.

/op-env

Load project environment from ./.env.1pass.

• Arguments: optional file name (default: .env.1pass)
• Autocomplete: .env.1pass, .env.local.1pass, etc.

/op-env-user

Load user-level environment from ~/.config/op-ssh/.env.1pass.

/op-get op://...

Get a specific secret and copy to OP_LAST_SECRET env var.

/op-create-env [filename]

Create a new project-level environment file with template.

Default: .env.1pass (if no filename provided)

Example:

/op-create-env              # Creates ./.env.1pass
/op-create-env .env.local   # Creates ./.env.local.1pass
/op-create-env .env.test    # Creates ./.env.test.1pass

Template includes common API keys:

• GITHUB_TOKEN
• OPENAI_API_KEY
• ANTHROPIC_API_KEY

/op-add-item VAR_NAME op://... [--global]

Add or update a 1Password secret reference in project or global env.

Project (default):

/op-add-item OPENAI_API_KEY op://Private/API-Keys/openai
/op-add-item DATABASE_URL op://Work/Database/prod

Global:

/op-add-item OPENAI_API_KEY op://Private/API-Keys/openai --global

Features:

• Auto-updates existing items automatically (no need to manually edit file first)
• Autocomplete shows vaults and items from op item list
• Smart matching by vault name or item name

/op-add-global-item VAR_NAME op://...

Similar to /op-add-item but specifically for global user env.

Examples:

/op-add-global-item OPENAI_API_KEY op://Private/API-Keys/openai
/op-add-global-item ANTHROPIC_API_KEY op://Private/API-Keys/anthropic

/op-list

List all loaded environment variables with their sources.

/op-config

Open the config directory and show user env file.

Setup Flow for New Project

# Step 1: Create project environment (defaults to .env.1pass)
/op-create-env

# Step 2: Add API keys easily (autocomplete helps find items)
/op-add-item OPENAI_API_KEY op://Private/API-Keys/openai
/op-add-item ANTHROPIC_API_KEY op://Private/API-Keys/anthropic

# Step 3: Load the environment
/op-env

# Step 4: Verify loaded variables
/op-status
/op-list

Global vs Project Environment

Cascade Order:

1. ~/.pi/.env (Pi-level)
2. ~/.config/op-ssh/.env.1pass (global)
3. ./.env.1pass (project, overrides global)

Environment Format

Both formats work in .env.1pass files:

# With export
OPENAI_API_KEY="op://Private/API-Keys/openai"

# Without export
OPENAI_API_KEY="op://Private/API-Keys/openai"

Both formats work in project env files:

# With export
DATABASE_URL="op://Work/Database/prod"

# Without export
DATABASE_URL="op://Work/Database/prod"

Troubleshooting

"Not signed in to 1Password"

Set OP_SERVICE_ACCOUNT_TOKEN in ~/.zshrc and reload.

Secrets not resolving

Check reference format: op://vault/item/field

Pi not loading extension

Restart Pi or run /reload in Pi command.

Item already exists

The commands automatically update existing items - just run them again with the new reference.

Autocomplete not showing items

Make sure op item list works and returns valid JSON. Run op login if needed.
