Jira and Linear own team coordination
Backlogs, sprints, priorities, and cross-team status live in the tracker. Day Shift does not model any of that, and it never will.
Day Shift vs Jira and Linear
Day Shift is not a ticket tracker. Keep yours.
Jira and Linear track product and team work. Day Shift manages the implementation contract for coding-agent work inside the repository. Keep the issue in your tracker; keep the handoff in your repo.
Division of labor
Different layers, not competing tools.
Day Shift owns the implementation contract
Scope, target paths, validation, implementation evidence, and reconciliation live in the repository, versioned beside the code they govern.
They meet at the handoff
A ticket says why the work matters and when it is due. The Day Shift task says exactly what the agent may change and what proves it worked.
How they work together
From ticket to reconciled implementation.
The tracker keeps its job at both ends. Day Shift fills the gap in the middle, where the agent actually changes code.
Ticket
The tracker holds the request, its priority, and its owner, unchanged.
Spec
Durable intent is registered in the repo so the plan traces to something reviewable.
Task
An implementation-sized task declares scope, target paths, and validation before the agent starts.
Reconciliation
Task evidence rolls up to one review checkpoint you can link back to the ticket.
No migration required
Add the repository layer without touching your tracker.
Day Shift is a local CLI, free to evaluate, with no integration work and no online activation. Your tracker workflow stays exactly as it is.
