Linear Core Workflow B: Projects & Cycles

Overview

Manage projects, cycles (sprints), milestones, and roadmaps using the Linear API. Projects group issues across teams with states (planned, started, paused, completed, canceled), target dates, and progress tracking. Cycles are time-boxed iterations (sprints) owned by a single team. Initiatives group projects at the organizational level.

Prerequisites

Linear SDK configured with API key or OAuth token
Understanding of Linear's hierarchy: Organization > Team > Cycle/Project > Issue
Team access with project create permissions

Instructions

Step 1: Project CRUD

Error	Cause	Solution
`Project not found`	Invalid project ID or deleted	Verify ID with `client.projects()`
`Cycle dates overlap`	Dates conflict with existing cycle	Check existing cycles: `team.cycles()`
`Permission denied`	No project access	Verify team membership
`Invalid date range`	`endsAt` before `startsAt`	Validate date ordering before API call
`Team not in project`	Issue team not in project's team list	Add team via `updateProject` first
