Internal LingTai mail: send/read/dismiss/reply, absolute-path addressing, delayed self-send time capsules, and full-body persistent notifications. Not internet email (see `mcp-manual`) or recurring schedules (see `shell-manual`).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Email Manual — internal mail
**Internal `.lingtai/` mail, not internet email.** Use the schema for routine
calls; this manual owns the exceptions. `action`, action-local `input`, and root
`reasoning` are required. Unknown/cross-action fields fail before mailbox I/O;
optional `null` means omitted. Root `summarize` is not an input field.
## First action
- **Arrival already visible:** reply on Email with `reply`/`reply_all`, then
`dismiss` the handled ID. Current replies do not clear unread state; see the
[documented Contract discrepancy](reference/addressing-and-replies/SKILL.md#same-channel-reply).
Use `read` for source records or attachments rather than rereading visible text.
- **Browse:** `email(action="check", input={}, reasoning="inspect inbox")`.
Use returned own-mailbox IDs; `search` is regex search. Never send raw local IDs
as references in mail/public prose.
- **New message:** verify the recipient directory, then `send` with an absolute
`address` (the recipient's agent-workdir path) and `message`. Bare names and
`@` addresses are refused; legacy mail without a route is answered as the
routing reference describes.

How to install
mdr add lingtai-ai/lingtai-kernel/email-manual@sha256:fedbd5d8651801e7The line at the top of this page pins the label v1.3.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
