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 (1,929 once invoked), scanned A, original, MIT.

A procedure for copying environment variables from 1Password into a local .env file using predefined mappings. It backs up the file, keeps unrelated variables, and avoids displaying secret values.

In plain words
What is it for?
Use it to set up development or production environment variables, select environment-specific keys, and sync them through the 1Password MCP connection or command-line tool.
Why use it?
It reduces manual copying of credentials and lowers the risk of losing existing settings or exposing secrets while updating local configuration.

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 9d 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.

name: sync-env-from-1password description: Sync .env from 1Password using env_var_mappings. triggers:

  • sync env from 1password
  • /sync_env_from_1password
  • sync-env-from-1password

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

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
