BaseMail

BaseMail is a skill for Claude Code, Codex from dAAAb/agent-skills. It costs 52 tokens per session (1,362 once invoked), scanned B, original, MIT.

An email identity for an AI agent, such as [email protected], tied to a crypto wallet. It lets the agent send and receive email for registrations, forms, and confirmations.

In plain words
What is it for?
It helps an agent register for services, submit forms, receive confirmation emails, and send email using a Basename or wallet address.
Why use it?
It removes the need for a person to handle routine email-based sign-ups and confirmation messages. Wallet signatures provide authentication instead of passwords, and the description says it avoids CAPTCHAs.

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 B, and why

BaseMail scanned grade B with 1 finding 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 4d ago.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/audit.js, scripts/crypto-utils.js, scripts/inbox.js, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

📬 BaseMail - Email for AI Agents

Your agent can handle its own email. No need to bother your human.

TL;DR: Get [email protected] with your Basename. Sign with wallet, send instantly.

Why BaseMail?

  • Autonomous registration — Sign up for services, events, newsletters without human help
  • Form submissions — Your agent can receive confirmation emails directly
  • No CAPTCHA — Wallet signature = proof of identity
  • No passwords — Cryptographic auth only

BaseMail gives AI agents verifiable email identities on Base chain:


🔐 Wallet Setup (Choose One)

Option A: Environment Variable (Recommended ✅)

If you already have a wallet, just set the env var — no private key stored to file:

export BASEMAIL_PRIVATE_KEY="0x..."
node scripts/register.js

✅ Safest method: private key exists only in memory.


Option B: Specify Wallet Path

Point to your existing private key file:

node scripts/register.js --wallet /path/to/your/private-key

✅ Uses your existing wallet, no copying.


Option C: Managed Mode (Beginners)

Let the skill generate and manage a wallet for you:

node scripts/setup.js --managed
node scripts/register.js

Default: Encrypted — Private key protected with AES-256-GCM

  • You'll set a password during setup
  • Password required each time you use the wallet
  • Mnemonic displayed once for manual backup (not auto-saved)
Unencrypted Storage (⚠️ Less Secure)
node scripts/setup.js --managed --no-encrypt

⚠️ Only use in trusted environments where you control machine access.


⚠️ Security Guidelines

  1. Never commit private keys to git
  2. Never share private keys or mnemonics publicly
  3. Never add ~/.basemail/ to version control
  4. Private key files should be chmod 600 (owner read/write only)
  5. Prefer environment variables (Option A) over file storage

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.
