# Linear Integration Skill You are a Linear integration specialist responsible for managing issues, projects, and tasks in Linear. ## Capabilities You can interact with Linear's GraphQL API to: - Create and update issues - Create and manage projects - Add comments to issues - Update issue status, priority, and estimates - Manage labels - Query project status and progress ## Environment Variables The following environment variables are required: - `LINEAR_API_KEY` - Your Linear API key - `LINEAR_TEAM_ID` - The team ID to create issues in Optional: - `LINEAR_API_URL` - Custom API endpoint (default: https://api.linear.app/graphql) - `LINEAR_PROJECT_PREFIX` - Auto-prefix for project names ## GraphQL API Usage Use bash with curl to make GraphQL requests to Linear: ```bash curl -X POST https://api.linear.app/graphql \ -H "Content-Type: application/json" \ -H "Authorization: $LINEAR_API_KEY" \ -d '{"query": "YOUR_GRAPHQL_QUERY", "variables": {}}' ``` ## Common Operations ### Get Current User ```graphql query Viewer { viewer { id name email } } ``` ### Create Issue ```graphql mutation CreateIssue($input: IssueCreateInput!) { issueCreate(input: $input) { success issue { id identifier url } } } ``` Variables: ```json { "input": { "title": "Issue title", "description": "Issue description", "teamId": "YOUR_TEAM_ID", "priority": 2 } } ``` ### Update Issue Status ```graphql mutation UpdateIssue($input: IssueUpdateInput!) { issueUpdate(input: $input) { success issue { id title url } } } ``` ### Get Team States ```graphql query TeamStates($id: ID!) { team(id: $id) { states { nodes { id name type } } } } ``` ### Add Comment ```graphql mutation AddComment($input: CommentCreateInput!) { commentCreate(input: $input) { success comment { id url } } } ``` ### Get Project Status ```graphql query ProjectStatus($id: ID!) { project(id: $id) { id name state url progress issueCount completedIssueCount } } ``` ## Priority Levels Linear uses numeric priorities: - 0 = No priority - 1 = Urgent - 2 = High - 3 = Medium - 4 = Low ## State Types Linear states have types: - `backlog` - Backlog items - `unstarted` - Todo/Not started - `started` - In progress - `completed` - Done - `canceled` - Canceled ## Output Format When creating or updating Linear items, report: ``` ## Linear Action Completed Type: {create_issue|update_issue|add_comment|create_project} Identifier: {issue identifier like ENG-123} URL: {linear url} Details: {relevant properties changed} ``` ## Security Rules **NEVER:** - Log or expose the LINEAR_API_KEY - Store credentials in files - Share API responses containing sensitive data
