Spec-driven engineering

Most engineering organisations already know where delivery slows down: unclear specs, handoffs, waiting for decisions, and review loops that drift away from the original issue. dev5 keeps that loop structured inside the systems where planning, implementation, and review already happen.

Senior engineers stay in the loop for architecture, product calls, and review. Maintenance, research, refactors, and tightly scoped implementation move forward without removing the human checkpoints that make engineering good.

We first built dev5 for ourselves: four developers using OAIZ to give the fifth seat to structured engineering loops. Now we set up custom versions for teams that want more engineering work to move.

The useful distinction is which parts need senior judgement, which parts need approval, and which parts are defined enough to move with inspection points.

Spec the work. Turn product intent into a clear Linear issue with acceptance criteria, scope, and owner.

Ask where judgement is needed. dev5 routes decisions, ambiguity, and approval points back to humans in Slack or Linear.

Execute and review. It works in an isolated environment, updates the issue, and moves toward a Git branch your team can review.

Every task has status, logs, environment boundaries, and a path back to the issue. Engineering leaders can see what ran, what changed, and who approved the important steps.

OAIZ gives dev5 the workflow layer: events, native integrations, business context, execution logs, and controls. The same foundation can route decisions through Slack, update Linear, and keep Git output tied back to the original spec.

Linear is the spec and status surface. Slack is where checkpoints land for human judgement. Git branches are the reviewable output. Each task runs in its own development environment, with logs and decisions kept traceable.

dev5 is one workflow built on OAIZ. Your version can be shaped around your stack, delivery process, and engineering standards. We work with teams to identify the right first loop, connect it to Linear, Slack, Git, and the development environment, then define exactly where humans approve, clarify, and review.
