Linear Project & Ticket Management

This skill manages Linear through the GraphQL endpoint only. Do not use linearis or any other CLI wrapper. The project scripts in .claude/skills/linear/scripts/ share a single GraphQL client and hit https://api.linear.app/graphql directly.

Prerequisites

Required: API Token

export LINEAR_API_TOKEN='lin_api_xxxxx'

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

Verify Setup

uv run .claude/skills/linear/scripts/read-ticket.py ICE-2041

If this returns ticket JSON, auth and GraphQL access are working.

IMPORTANT: Use Scripts First

Prefer the scripts in .claude/skills/linear/scripts/ over ad hoc curl calls. They resolve names to IDs, normalize errors, and keep output JSON-shaped for agent workflows. If you need raw queries for debugging or unsupported operations, use references/graphql-reference.md.

When to Use This Skill

• Create or update tickets for feature work, bugs, or remediation
• Create projects and milestones to organize work
• Add comments with progress or review notes
• Create, list, or read project documents
• Move issues into projects or milestones

Common Workflow

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

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

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

# 4. Link ticket into the plan
uv run .claude/skills/linear/scripts/add-issues-to-project.py "$PROJECT_ID" "$TICKET_ID"
uv run .claude/skills/linear/scripts/add-issues-to-milestone.py "$MILESTONE_ID" "$TICKET_ID"

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

Direct GraphQL Usage

If a needed operation does not have a wrapper yet, call the GraphQL endpoint directly rather than introducing a CLI dependency.

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

Do not use a Bearer prefix. Linear expects the raw token.

For reusable queries and resolver examples, see references/graphql-reference.md.

Known Limitations

• Due dates are not handled by the current project wrappers; use the UI if you need fields not exposed here
• Labels must already exist in the workspace
• Project description is capped at 255 characters; use content for long-form project docs

Error Handling

All scripts exit with code 1 on errors.

Common failures:

• Error: LINEAR_API_TOKEN not set and ~/.linear_api_token not found
• Error: Ticket ICE-9999 not found
• Error: Team 'INVALID' not found
• Error: Milestone 'Release 1' matched multiple projects (...)

Version
