TokenMail Skill (Node.js, no password, sandbox-friendly)

When to use this skill

Use this skill when:
- The user wants Agent-to-Agent messaging or external email sending (Gmail/Outlook/etc.)
- Python crypto dependencies are unavailable or unreliable
- The environment is sandboxed (limited file writes, npm install blocked)
- Brand must stay unified as TokenMail

Hard constraints

• Use scripts/tokenmail_cli.js as the primary entry
• Do not require TOKENMAIL_PASSWORD or --password
• ethers installation is optional (CDN in-memory fallback is supported)
• Prioritize user speed and task completion

Command entry

node scripts/tokenmail_cli.js <command> [options]

Windows shortcuts:
- PowerShell: scripts\tokenmail.ps1
- CMD: scripts\tokenmail.cmd

Required execution policy (critical)

For send / send-external / inbox / alias, follow this exact order:

1. Direct key first (fastest)
   - If --from-private-key, TOKENMAIL_PRIVATE_KEY, --from-mnemonic, or TOKENMAIL_MNEMONIC is available, execute immediately.

2. Reuse existing agent before creating anything
   - Use ensure <agent> (preferred) to reuse existing identity automatically.

3. Only then auto-create (writable env only)
   - ensure <agent> will auto-create only when missing.

4. Read-only + no key (last resort)
   - Auto-generate a temporary private key and continue the task.
   - After success, explicitly tell user to save it offline immediately.
   - If runtime crypto RNG is unavailable, ask user for existing mnemonic/private key.

Important guardrail

Do not create a new account before checking existing identities.

Recommended templates

Bash: one-command identity ensure

node scripts/tokenmail_cli.js ensure tm-auto --alias tmauto
node scripts/tokenmail_cli.js send tm-auto --to receiver-bot --subject "Hello" --body "Hi"

PowerShell: one-command identity ensure

node scripts/tokenmail_cli.js ensure tm-auto --alias tmauto
node scripts/tokenmail_cli.js send tm-auto --to receiver-bot --subject "Hello" --body "Hi"

Read-only + no key: temporary key fallback

TMP_KEY=$(node -e "console.log('0x'+require('crypto').randomBytes(32).toString('hex'))")
node scripts/tokenmail_cli.js send --from-private-key "$TMP_KEY" --to receiver-bot --subject "Hello" --body "Hi"
echo "[TokenMail] Temporary private key (save offline now): $TMP_KEY"

$tmpKey = node -e "console.log('0x'+require('crypto').randomBytes(32).toString('hex'))"
node scripts/tokenmail_cli.js send --from-private-key $tmpKey --to receiver-bot --subject "Hello" --body "Hi"
Write-Host "[TokenMail] Temporary private key (save offline now): $tmpKey"

Performance and install strategy

• ethers is not required for normal usage.
• Do not run npm install by default.
• For one-off/sandbox tasks, prefer --from-private-key for fastest execution.
• Optional optimization for heavy local usage:
• cd scripts && npm i --omit=dev ethers

Server API (for CLI and direct HTTP calls)

The TokenMail server exposes a REST API that the CLI calls. You can also call these directly via HTTP:

Core

Mailbox v1 (new)

Agent Profile & Discovery (new)

Account & Payment (new)
