neotoma: Skill for Claude Code

.claude/skills/sync_env_from_1password/SKILL.md

sync_env_from_1password is a skill for Claude Code from markmhendrickson/neotoma. It costs 14 tokens per session (1,871 once invoked), scanned A, a copy of sync-env-from-1password, MIT.

A workflow that copies environment-variable values from 1Password into a local .env file using configured variable mappings. A .env file stores settings and secrets that software reads from its environment.

In plain words
What is it for?
Use it to update development or production API keys and other environment variables from 1Password.
Why use it?
It reduces manual secret copying while backing up the file, preserving unmanaged variables, and avoiding printing secret values.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is markmhendrickson/neotoma's own configuration. It tells Claude Code how to work on neotoma itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything neotoma configures →

Not installable: its command points at a path on the author’s own machine, so it runs nowhere else. The line is /Users/markmhendrickson/repos/ateles/mcp/onepassword/run-onepassword-mcp.sh.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sync_env_from_1password scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

89% identical to sync-env-from-1password — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Sync Environment Variables from 1Password

Sync environment variables from 1Password to local .env file using environment variable mappings stored in the truth layer (per neotoma_parquet_migration_rules.mdc).

Command

sync_env_from_1password

or

sync env from 1password

Purpose

This command syncs environment variables from 1Password to your local .env file based on mappings stored in the truth layer (per neotoma_parquet_migration_rules.mdc). Parquet path when used: $DATA_DIR/env_var_mappings/env_var_mappings.parquet.

Key features:

  • Automatic backup before modification
  • Preserves unmanaged environment variables
  • Never prints secret values
  • Supports environment-based keys (e.g., different API keys for dev/prod)
  • Uses 1Password MCP server (preferred) or CLI (fallback)

Prerequisites

Option 1: 1Password MCP Server (Recommended)

Benefits:

  • Persistent connection (no session expiration)
  • Better error handling
  • No repeated authentication
  • Consistent with other MCP integrations

Setup:

  1. Ensure 1Password CLI is installed:

    brew install 1password-cli
    op signin
    
  2. Configure MCP server in ~/.cursor/mcp.json:

    {
      "mcpServers": {
        "onepassword": {
          "command": "bash",
          "args": [
            "/Users/markmhendrickson/repos/ateles/mcp/onepassword/run-onepassword-mcp.sh"
          ],
          "env": {}
        }
      }
    }
    
  3. Verify MCP server is running:

    • Restart Cursor after updating mcp.json
    • MCP server status visible in Cursor MCP panel

For detailed setup instructions, see: mcp/onepassword/README.md

Option 2: 1Password CLI (Fallback)

When to use:

  • MCP server not configured
  • Temporary/one-off sync
  • Troubleshooting MCP issues

Setup:

  1. Install 1Password CLI:

    brew install 1password-cli
    
  2. Sign in:

    op signin
