Linear Project & Ticket Management

Comprehensive skill for Linear operations including tickets, projects, milestones, and documents.

Prerequisites

Required: linearis CLI

npm install -g linearis

Required: API Token

export LINEAR_API_TOKEN='lin_api_xxxxx'

Get token from: Linear → Settings → Security & Access → Personal API keys

Verify Setup

uv run ${CLAUDE_PLUGIN_ROOT}/skills/linear/scripts/read-ticket.py ICE-2041

If this returns ticket JSON, you're good to go.

IMPORTANT: Use Scripts Only

NEVER call the linearis CLI directly. Always use the wrapper scripts below.

The scripts are in ${CLAUDE_PLUGIN_ROOT}/skills/linear/scripts/. They handle CLI quirks, parse output, and give consistent JSON results. If you need raw CLI details for debugging, see references/linearis-reference.md.

When to Use This Skill

• Create tickets for security issues or feature work
• Create projects to group related tickets with goals and timelines
• Create milestones to track project phases with due dates
• Create documents to attach reference material to projects
• Track progress by updating ticket status and adding comments

Scripts Overview

Script	Purpose
list-issues.py	List issues for a team
search-issues.py	Search issues by query
create-ticket.py	Create a ticket
read-ticket.py	Read ticket details
update-ticket.py	Update ticket status
add-comment.py	Add comment to ticket
create-project.py	Create a project
add-issues-to-project.py	Add tickets to a project

Project Operations

Create Project

uv run ${CLAUDE_PLUGIN_ROOT}/skills/linear/scripts/create-project.py "Security Remediation Q1" \
  --team ICE-T \
  --description "Eliminate all High severity alerts" \
  --priority 1 \

• content - Full markdown document, shown on project detail page

Add Issues to Project

# Single issue
uv run ${CLAUDE_PLUGIN_ROOT}/skills/linear/scripts/add-issues-to-project.py PROJECT_UUID ICE-2027

# Multiple issues
uv run ${CLAUDE_PLUGIN_ROOT}/skills/linear/scripts/add-issues-to-project.py PROJECT_UUID ICE-2027 ICE-2028 ICE-2029

# Comma-separated
uv run ${CLAUDE_PLUGIN_ROOT}/skills/linear/scripts/add-issues-to-project.py PROJECT_UUID --issues ICE-2027,ICE-2028

---

Milestone Operations

Create Milestone

uv run ${CLAUDE_PLUGIN_ROOT}/skills/linear/scripts/create-milestone.py "P1: Critical Fixes" \
  --project PROJECT_UUID \
  --description "RCE and exposed secrets" \
  --target-date 2026-02-09 \

Note: linearis CLI does not support milestone operations. Use the scripts above or GraphQL API directly.

---

Document Operations

Create Document

# With inline content
uv run ${CLAUDE_PLUGIN_ROOT}/skills/linear/scripts/create-document.py \
  --title "Security Findings Report" \
  --project PROJECT_UUID \
  --content "# Report\n\nDetails here..."

# From file
uv run ${CLAUDE_PLUGIN_ROOT}/skills/linear/scripts/create-document.py \
  --title "Security Findings Report" \

  --content-file ./report.md \
  --json

Options:

• --title (required) - Document title
• --project (required) - Project name or UUID
• --content - Markdown content
• --content-file - Read content from file

List/Read Documents

No wrapper script yet. Use the linearis CLI directly (see references/linearis-reference.md):

linearis documents list --project <project>
linearis documents read <document-id>

---

Common Workflows

Create Project with Milestones and Issues

# 1. Create project
PROJECT_ID=$(uv run ${CLAUDE_PLUGIN_ROOT}/skills/linear/scripts/create-project.py \
  "Security Remediation" \
  --team ICE-T \
  --description "Eliminate all security vulnerabilities")

# 2. Create milestones
P1_ID=$(uv run ${CLAUDE_PLUGIN_ROOT}/skills/linear/scripts/create-milestone.py \
  "P1: Critical" \
  --project $PROJECT_ID \
  --target-date 2026-02-09)

# 3. Create tickets
TICKET_ID=$(uv run ${CLAUDE_PLUGIN_ROOT}/skills/linear/scripts/create-ticket.py \
  "Patch CVE-2024-1234" \
  --team ICE-T \
  --priority 1)

# 4. Add tickets to project and milestone
uv run ${CLAUDE_PLUGIN_ROOT}/skills/linear/scripts/add-issues-to-project.py $PROJECT_ID $TICKET_ID
uv run ${CLAUDE_PLUGIN_ROOT}/skills/linear/scripts/add-issues-to-milestone.py $P1_ID $TICKET_ID

# 5. Attach documentation
uv run ${CLAUDE_PLUGIN_ROOT}/skills/linear/scripts/create-document.py \
  --title "Findings Report" \
  --project $PROJECT_ID \
  --content-file ./report.md

Batch Add Issues to Project

# Get project ID
PROJECT_ID="9e05263f-ed01-4b85-9c74-569fd1a0ce13"

# Add range of issues
uv run ${CLAUDE_PLUGIN_ROOT}/skills/linear/scripts/add-issues-to-project.py $PROJECT_ID \
  --issues ICE-2027,ICE-2028,ICE-2029,ICE-2030

GraphQL API Reference

For operations not supported by linearis CLI, use the Linear GraphQL API directly.

Authentication

curl -X POST https://api.linear.app/graphql \
  -H "Content-Type: application/json" \
  -H "Authorization: $LINEAR_API_TOKEN" \
  -d '{"query": "{ viewer { id name } }"}'

Note: Do NOT use Bearer prefix - Linear uses the raw token.

Create Project

mutation CreateProject($input: ProjectCreateInput!) {
  projectCreate(input: $input) {
    success
    project { id name url }
  }
}

Variables:

{
  "input": {
    "teamIds": ["team-uuid"],
    "name": "Project Name",
    "description": "Short description (max 255 chars)",
    "priority": 1
  }
}

Update Project Content

mutation UpdateProject($id: String!, $input: ProjectUpdateInput!) {
  projectUpdate(id: $id, input: $input) {
    success
  }
}

Variables:

{
  "id": "project-uuid",
  "input": {
    "content": "# Full markdown content here"
  }
}

Add Issue to Project

mutation UpdateIssue($id: String!, $input: IssueUpdateInput!) {
  issueUpdate(id: $id, input: $input) {
    success
  }
}

Variables:

{
  "id": "issue-uuid",
  "input": {
    "projectId": "project-uuid"
  }
}

Add Issue to Milestone

{
  "id": "issue-uuid",
  "input": {
    "projectMilestoneId": "milestone-uuid"
  }
}

Get Team ID

{ teams { nodes { id name key } } }

Get Issue UUID from Identifier

{ issue(id: "ICE-2027") { id } }

---

Known Limitations

• Projects: Create/update via create-project.py script (uses GraphQL under the hood)
• Due dates: Cannot be set on tickets — use Linear UI
• Custom labels: May not exist in workspace; use existing labels or create via UI
• Description field: Max 255 characters (use content for full text on projects)

---

Error Handling

All scripts exit with code 1 on errors:

• Missing token: Error: LINEAR_API_TOKEN not set and ~/.linear_api_token not found
• Ticket not found: Error: Ticket ICE-9999 not found
• Invalid team: Error: Team 'INVALID' not found
• linearis not installed: Error: linearis CLI not found. Install with: npm install -g linearis
