    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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

gmcli 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 2mo 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.

What it actually says

Gmail CLI

Command-line interface for Gmail operations.

Installation

npm install -g @mariozechner/gmcli

Setup

Google Cloud Console (one-time)

  1. Create a new project (or select existing)
  2. Enable the Gmail API
  3. Set app name in OAuth branding
  4. Add test users (all Gmail addresses you want to use)
  5. Create OAuth client:
    • Click "Create Client"
    • Application type: "Desktop app"
    • Download the JSON file

Configure gmcli

First check if already configured:

gmcli accounts list

If no accounts, guide the user through setup:

  1. Ask if they have a Google Cloud project with Gmail API enabled
  2. If not, walk them through the Google Cloud Console steps above
  3. Have them download the OAuth credentials JSON
  4. Run: gmcli accounts credentials ~/path/to/credentials.json
  5. Run: gmcli accounts add <email> (use --manual for browserless OAuth)

Usage

Run gmcli --help for full command reference.

Common operations:

  • gmcli <email> search "<query>" - Search emails using Gmail query syntax
  • gmcli <email> thread <threadId> - Read a thread with all messages
  • gmcli <email> send --to <emails> --subject <s> --body <b> - Send email
  • gmcli <email> labels list - List all labels
  • gmcli <email> drafts list - List drafts

Data Storage

  • ~/.gmcli/credentials.json - OAuth client credentials
  • ~/.gmcli/accounts.json - Account tokens
  • ~/.gmcli/attachments/ - Downloaded attachments
Changes

What this file has done since we first saw it

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.
