Linear Expert

Master-level expertise in Linear configuration, workflow design, GraphQL API mastery, Cycle and Project management, Initiative-level roadmaps, triage automation, GitHub integration, and migration from Jira. Covers everything from workspace setup to programmatic bulk operations against the Linear API.

Overview

Linear is an opinionated, keyboard-driven issue tracker built around a strict data model (Team → Project → Issue → Sub-issue) and a GraphQL-only public API. Unlike Jira, Linear's strength is its lack of configurability: there is one workflow shape (Backlog → Unstarted → Started → Completed → Canceled), one priority scale (0-4), and a tight set of first-class concepts (Cycles, Projects, Initiatives, Labels, Milestones). The job of a Linear expert is to operate fluently inside those rails while extending the system through the API, automations, and integrations.

Core Capabilities

• Workspace & team configuration — URL keys, SSO, team keys, cycle cadence, estimation scales, workflow states, label taxonomy
• Planning hierarchy — Cycles (sprints), Projects + Milestones, Initiatives, and Roadmap views
• Triage automation — inbound routing from Slack, support, GitHub Issues; daily triage SOP
• GraphQL API mastery — query/mutation authoring, pagination, batch mutations, webhooks, rate-limit hygiene
• GitHub integration — magic-word auto-link/auto-close, branch auto-linking, PR-state syncing
• Bulk operations & migration — API-driven bulk edits and Jira → Linear migration planning

When to Use

• Setting up a new Linear workspace, team, or project from scratch
• Designing Cycle cadence, triage rules, and SLA workflows
• Writing GraphQL queries and mutations against the Linear API
• Configuring GitHub PR auto-link/auto-close and Slack notifications
• Building Initiative / Project / Milestone hierarchies for executive roadmaps
• Running bulk operations (relabel, retarget, reassign) across hundreds of issues
• Migrating an existing Jira instance to Linear without losing history
• Diagnosing why automations, sub-issues, or triage rules are not firing as expected

Quick Start

Linear's API is GraphQL-only at https://api.linear.app/graphql; auth via personal API key (Authorization: <key>) or OAuth2.

linear_query() {
  curl -s -X POST https://api.linear.app/graphql \
    -H "Authorization: $LINEAR_API_KEY" \
    -H "Content-Type: application/json" \
    -d "{\"query\": \"$1\"}"
}

Cache team/label/state UUIDs locally, use nested selection to avoid N+1 calls, and prefer webhooks over polling. See the references below for the full query catalog and operating workflows.

Scope & Limitations

In Scope: Linear workspace, team, and project configuration; cycle and project planning; Initiative and Roadmap hierarchy; triage workflow design; GitHub PR integration; GraphQL query and mutation authoring; bulk operations via API; webhook configuration; Jira → Linear migration planning and execution.

Out of Scope: Jira-side configuration and migration freeze (hand off to jira-expert/); Notion documentation pages for Linear roadmaps (hand off to notion-pm/); strategic prioritization and OKR setting (hand off to senior-pm/, execution/brainstorm-okrs/); sprint coaching and team health (hand off to scrum-master/); release notes generation from Linear issues (hand off to execution/release-notes/).

Limitations: Linear has no custom fields; all extension happens through labels, descriptions, or external systems. The free tier caps at 250 issues per workspace and excludes Initiatives and SAML. API rate limits are workspace-wide and shared across all keys; heavy automation may require coordination. Importers preserve most history but cannot recreate Jira's custom workflow states; mapping is many-to-five. GraphQL schema evolves continuously; pin client code to the deprecation calendar.
