Open the technical deep diveA read-and-prioritize layer for personal assistants
Amanuensis sits between personal information sources and delivery channels, using context and priority to decide what deserves the foreground. Urgent items go out immediately; necessary but not urgent items are held back until a better time. This protects attention without discarding signals that may matter later.
Amanuensis focuses on one job: deciding what deserves attention, and when. Its reasoning and converse flows are bounded to information triage; general-purpose conversation, long-term memory, and privileged actions stay outside this boundary.
Within the Yaaa ops architecture, Amanuensis is a concrete subsystem implementation spanning reasoning, converse, and attention-aware delivery. Yaaa defines how those subsystems are composed and governed; Amanuensis implements the information-triage path.
Sample walkthroughAttention is scarce; information is overwhelming
Urgent or not, messages from every source draw attention just to be processed. How often is a push notification just spam? Without triage, the message is noisy: more material to scan, distrust, and discard. Triage changes the equation by ranking each signal against context, timing, and an actual plan.
Signal buried in noise remains noise.
Signal after triage is a resource.
Resources, organized and reusable, become assets.
Aggregation, triage, restrained delivery
Mail, calendar, task, and notification tools move information reliably. Assistants can summarize it one item at a time. The missing layer compares unlike sources against the same private context, then makes the delivery decision before anything interrupts.
A private secretary sorting the morning mail made the same judgment: discard the junk, file the routine, interrupt only for what cannot wait. Amanuensis rebuilds that narrow role between existing sources and delivery channels. Conversation, long-term memory, and privileged actions remain outside its boundary.
What's important depends on the context
A discount flyer is ambient when there is no purchase plan. Repeated as an immediate notification, it becomes spam and a spending trap. When a plan already exists - for example, replace a desk chair this month - the same offer becomes useful. Amanuensis keeps it ambient by default, then surfaces it when the offer matches a real plan. Plans arrive the same way anything else does: a memo is ingested as a record, then read as context when other items are judged.
Three responsibilities, one inspectable trace
Amanuensis separates collection, judgment, and delivery so each boundary can be tested independently. A stable item ID connects the stages; policy gates control where sensitive content may be inferred and delivered.
01 / Gather
Mail, tasks, feeds, and notes enter one stable record shape, with repeats removed at the edge.
02 / Judge
Private plans, timing, and intent turn the same signal into foreground, digest, quiet, or drop.
03 / Deliver
Deterministic gates decide whether an item may interrupt, wait for a digest, or remain unsent.

The design, interface contracts, and reconstructed example trace are public. The implementation remains in a private repository while its interfaces evolve. A public release requires dependency and licensing review, secret scanning, provenance checks, and sufficient documentation - not only a change in repository visibility.
