Found live on 2026-10-07 (bring-up on nisse-testing-operator/nisse-bringup,
Opus as driver):
- The driver's prose nudge went into the system prompt, so the retry ended
on the model's own reply. Opus 5.5 refuses that ("does not support
assistant message prefill. The conversation must end with a user
message"). The nudge is now a harness fact in the conversation. The
delegation harness's prose path did the same and is fixed likewise.
- A helper's first request ended with its own delegation_started event,
rendered as an assistant message: every delegation would have failed on
Opus. The helper now sees it as the harness handing over its task.
- model_contract checks that every request ends on the user's side, so
scripted tests catch this from now on (each fix is mutation-checked).
- `status` (and `details`) in an item's thread were taken as replies: they
woke the driver and cancelled a bug's countdown. They now answer at once
and change nothing.
- The driver had no way to answer a remark without changing the item, so it
answered in prose. Every run woken by a message (or a review comment) now
offers `reply`, which answers where asked and returns to the very wait
that was interrupted.
Also: scripts/bringup-repo.sh makes the bring-up's test repository
(make_repo/delete_repo, split out of fresh_repo), and made repositories get
the agent's labels (bug, discuss, design).
Tests: test_loop_live_fixes.py (one per finding); the walk sends `status`
into threads (status_changes_nothing) and its scripted driver sometimes
answers remarks with reply.

Nisse
Two self-hosted AI agents sharing a common library, named for the Nordic farm spirit that keeps the place running overnight and expects to be treated well in return.
| Package | Role |
|---|---|
nisse-core/ |
Shared library both agents sit on (Part L) |
nisse-dev/ |
Dev Agent — plans and implements software projects (Part D) |
nisse-ops/ |
Sysadmin Agent — operates infrastructure (Part O) |
One repository, three packages. The library does not exist as code yet: it is
extracted from nisse-dev once that agent works (build-order step 10), as a
package split within this tree.
Architecture
The system-level specification lives at
docs/Architecture.md. It covers the
shared library, both agents, the supporting services, the build order, and the
remaining open decisions.
