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, thendismissthe handled ID. Current replies do not clear unread state; see the documented Contract discrepancy. Usereadfor source records or attachments rather than rereading visible text. - Browse:
email(action="check", input={}, reasoning="inspect inbox"). Use returned own-mailbox IDs;searchis regex search. Never send raw local IDs as references in mail/public prose. - New message: verify the recipient directory, then
sendwith an absoluteaddress(the recipient's agent-workdir path) andmessage. Bare names and@addresses are refused; legacy mail without a route is answered as the routing reference describes. - Address a sender by non-empty
sender_nickname, elsesender_name. Reply on the arrival channel, not private text output. Read the routing reference before an exceptional channel pivot.
A sent receipt is scheduling evidence, not recipient acceptance. Do not blindly
retry a bounce or failed call: earlier deliveries may exist. Delayed mail depends
on this process staying alive. Non-self POSIX delivery snapshots attachments;
self-send does not. There is no attachment source-root/size limit: share only
explicitly authorized files. Details below; none of these limits authorizes
configuration changes, lifecycle intervention, or cleanup.
Routing table
| Need | Read |
|---|---|
| Absolute recipient paths, return routes, legacy mail without a route, identity, replies | Addressing and replies |
| Filters/folders, self-send, attachments, storage and retention | Actions and storage |
| Liveness, delivery ordering, bounces, unread/overflow handling | Notifications and delivery |
| SHOW sources, changes, timing and redaction | Settings reference |
Settings anchors
settings takes {} and performs no mailbox I/O. Rows contain exactly key,
current, default, configurable, comment; missing applied truth fails the
whole inventory as SETTINGS_UNAVAILABLE, with no partial rows/private detail.
manual also takes {} and returns the installed body/path without mailbox I/O.
Keep exact IDs/bodies when needed; reserve result summarization for bulky reads,
not short receipts or procedures being followed.
Send body character limit
send.body_char_limit: body cap.
Check result token limit
check.result_token_limit: check budget.
Unread notification entry limit
unread.max_entries: entry projection.
Pseudo-agent subscriptions
manifest.pseudo_agent_subscriptions: redacted applied snapshot.
Cleanup / Footprint
Email owns mailbox/ and .notification/email.json; keep decision/handoff evidence.
Use the retention and inspection procedure,
not ad-hoc deletion. Bug filing goes through lingtai-issue-report with permission.
