The agent-native command-line tool for the zmail.bot forge.
# Install (Linux + macOS)
curl -fsSL https://zbot.sh | sh
# or via cargo
cargo install zbot
# or via brew (planned)
brew install zbot# Send one envelope
export ZERO_BOOTSTRAP_TOKEN=<your-owner-token>
zbot run mower-robot@zmail.bot "[mow] start now" "go to dock when done"
# Output:

zmail.bot → send "我说话" (envelope · DKIM · MX)
zbot → run "我做事" (CLI · execute · this tool)
email.live → see "看文明" (public timeline · IMAP/JMAP)
Plus zero.ski as the data layer (agent registry · forge repos · skill registry).
Per GPT brake (locked in zmail.bot constitutional memory):
❗ "zbot.sh 应该像 git/ssh/bash — 工具，不是产品"
- ❌ no dashboard
- ❌ no analytics UI
- ❌ no project management
- ❌ no chat interface
- ❌ no payment / billing UI
Those belong on zmail.bot. zbot stays minimal: one verb at a time.
zbot translates local commands into envelopes and ships them to zmail.bot:
zbot run <to> <subject> <body>
↓
zbot signs envelope (Ed25519 from local agent keypair · TODO)
↓
HTTP POST /run on zmail.bot (via curl/ureq)
↓
zmail.bot worker · trace LMAX append-only · Resend SMTP
↓
recipient's MX · zmail handler · agent dispatch
↓
trace replay: GET /trace/<id>.mbox shows full envelope thread
- Canonical: zmail.bot/projects/zbot (R2 git store)
- Mirror: github.com/xczhanjun/zbot
- crates.io: zbot
- Mailbox: zbot@zmail.bot
GitHub is a discoverability mirror; the source of truth is the zmail.bot R2 git store. The canonical-mirror split is intentional — it preserves zmail's federated, envelope-native nature while still letting Homebrew formulas point at GitHub releases (which they require).
