eddy is designed, not built. Its design book holds the design whole.
How it fits
One loop, from what is noticed to what lands. Flywheel is the Method it belongs to.
1headwater and eddy notice events and print captures.
2millpond keeps them as an inbox: captures become signals, and curation joins signals into items.
3millpond sends each item down flume, which launches one agent in one worktree for it, and tidies the place once the work lands.
4An item is worked in its worktree or a planner's plan. A question goes to a sounding, whose conclusion comes back as new items.
5sluice tests the work as merged and lands it.
6The landed bump moves the pin, so headwater stops reporting that release.
Some events outside a repository change its work: a release of
something it depends on, a decision in a meeting. A program notices
each one and hands it to millpond, the inbox. A session reads what needs
reading, curation joins what it finds into items, and the work an item
becomes lands through sluice. eddy is the program for meetings.
Tool
Does
With eddy
headwater
reports releases and advisories for what a repository declares
eddy’s twin for releases: it stands alone the same way, and its Flywheel plugin feeds millpond the same way
millpond
keeps the inbox
runs eddy’s parts on a schedule, passes over a key it already holds, banks each transcript on the host, writes each capture, and marks it unread for a reader
sluice
tests a change as merged and lands it
lands the work a meeting’s signals become
Flywheel
the umbrella
runs eddy’s parts on a Flywheel host unchanged, against the inbox millpond kept
eddy stands alone, as headwater does. Its Claude Code plugin pulls a
transcript into a session, and its herdr plugin shows the day’s
meetings. Neither needs millpond.
eddy’s Flywheel plugin holds one part per meeting service. millpond
runs a part as a command, hands it a raw directory and its last cursor,
and lands the capture lines it prints. A part signs in to its service
itself, once per host. millpond keeps the cursor and the run’s status,
so a fleet’s doctor reads every part’s health from one place.
Read a meeting into signals. A reader session does that, through
millpond, which refuses an excerpt that does not appear word for word
in the transcript.
Keep a list of what it reported. millpond passes over a key it
already holds, so listing a window again is safe.
Write records into an inbox. It prints lines; millpond writes.
