Factory
Layer
A one-page spec in,
a project with green tests out.
Watch
The factory in three minutes.
What an agent needs to build software
The brain needs hands and memory.
A model can plan and reason, but on its own it does not write code, run tests or fix anything, and it forgets everything between sessions.
Mozaik
Agent framework by JigJoy. Three agents plan the work, write acceptance checks from the spec and review every task, several of them at once.
Agentic Playbooks
Work as a graph of agents and scripts: an agent writes code, scripts check it, fix rounds run until it passes. Repeatable work becomes a new playbook.
open source
Open Second Brain
Memory for agents in plain Markdown. The factory recalls similar runs before planning and saves the outcome after. 500+ stars on GitHub.
open sourceFactory Layer
The connecting layer between brain, hands and memory. It takes a project from spec to delivery: hands out the work, checks every result and ships a finished project.
Built at the hackathon
One command. No human in the loop.
Three Mozaik agents
The Architect plans tasks, the Acceptance analyst turns the spec's examples into checks, the Critic judges every finished task.
build-task playbook
Code, quality gates and review run in parallel; two fix rounds on Sonnet, then one on Opus. Merge conflicts go to the integrate playbook.
One state, one writer
Every step is saved before it runs, so a run survives a crash and continues from the same point.
Recovery
A failed task is retried, repaired with a hint or re-planned by the brain, while the other tasks keep running.
Clean delivery
Install, build, tests and every acceptance check once more on a clean copy of main. A cutoff stops everything on time.
Report and trace
Time, cost and models of every task, a full event trace and a log of every human intervention.
One run
From a spec to a delivered project.
- Spec in. A one-page Markdown spec with examples: what to build and how it should behave.
- Plan and acceptance, at once. The Architect splits the spec into tasks while the Acceptance analyst writes checks; the Critic reviews the checks.
- Hands at work. Each task runs its own build-task playbook in its own git worktree; independent tasks build in parallel.
- Judge and merge. The Critic judges each task; an accepted task joins main only if every check that passed before still passes.
- Deliver. A clean copy is built and checked again, then delivered with a report and a full trace.
Test run
Two specs in parallel, no human help.
