Linear — Issue & Project Management

Manage Linear issues, projects, and teams directly via the GraphQL API using curl. No MCP server, no OAuth flow, no extra dependencies.

Setup

Get a personal API key from Linear Settings > API > Personal API keys
Set LINEAR_API_KEY in your environment (via hermes setup or your env config)

API Basics

Endpoint: https://api.linear.app/graphql (POST)
Auth header: Authorization: $LINEAR_API_KEY (no "Bearer" prefix for API keys)
All requests are POST with Content-Type: application/json
Both UUIDs and short identifiers (e.g., ENG-123) work for issue(id:)

Base curl pattern:

bash

curl -s -X POST https://api.linear.app/graphql \
  -H "Authorization: $LINEAR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "{ viewer { id name } }"}' | python3 -m json.tool

Workflow States

Linear uses WorkflowState objects with a type field. 6 state types:

Type	Description
`triage`	Incoming issues needing review
`backlog`	Acknowledged but not yet planned
`unstarted`	Planned/ready but not started
`started`	Actively being worked on
`completed`	Done
`canceled`	Won't do

Each team has its own named states (e.g., "In Progress" is type started). To change an issue's status, you need the stateId (UUID) of the target state — query workflow states first.

Priority values: 0 = None, 1 = Urgent, 2 = High, 3 = Medium, 4 = Low

curl -s -X POST https://api.linear.app/graphql \
  -H "Authorization: $LINEAR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "mutation($input: IssueCreateInput!) { issueCreate(input: $input) { success issue { id identifier title url } } }",
    "variables": {
      "input": {
        "teamId": "TEAM_UUID",

bash

curl -s -X POST https://api.linear.app/graphql \
  -H "Authorization: $LINEAR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "mutation { issueUpdate(id: \"ENG-123\", input: { stateId: \"STATE_UUID\" }) { success issue { identifier state { name type } } } }"}' | python3 -m json.tool

  -H "Content-Type: application/json" \
  -d '{"query": "mutation { issueUpdate(id: \"ENG-123\", input: { dueDate: \"2026-04-01\" }) { success issue { identifier dueDate } } }"}' | python3 -m json.tool

Add labels to an issue

bash

curl -s -X POST https://api.linear.app/graphql \
  -H "Authorization: $LINEAR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "mutation { issueUpdate(id: \"ENG-123\", input: { labelIds: [\"LABEL_UUID_1\", \"LABEL_UUID_2\"] }) { success issue { identifier labels { nodes { name } } } } }"}' | python3 -m json.tool

bash

curl -s -X POST https://api.linear.app/graphql \
  -H "Authorization: $LINEAR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "mutation { issueUpdate(id: \"ENG-123\", input: { projectId: \"PROJECT_UUID\" }) { success issue { identifier project { name } } } }"}' | python3 -m json.tool

Create a project

bash

curl -s -X POST https://api.linear.app/graphql \
  -H "Authorization: $LINEAR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "mutation($input: ProjectCreateInput!) { projectCreate(input: $input) { success project { id name url } } }",
    "variables": {
      "input": {
        "name": "Q2 Auth Overhaul",
        "description": "Replace legacy auth with OAuth2 and PKCE",
        "teamIds": ["TEAM_UUID"]
      }
    }
  }' | python3 -m json.tool

Pagination

Linear uses Relay-style cursor pagination:

bash

# First page
curl -s -X POST https://api.linear.app/graphql \
  -H "Authorization: $LINEAR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "{ issues(first: 20) { nodes { identifier title } pageInfo { hasNextPage endCursor } } }"}' | python3 -m json.tool

# Next page — use endCursor from previous response
curl -s -X POST https://api.linear.app/graphql \
  -H "Authorization: $LINEAR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "{ issues(first: 20, after: \"CURSOR_FROM_PREVIOUS\") { nodes { identifier title } pageInfo { hasNextPage endCursor } } }"}' | python3 -m json.tool

Default page size: 50. Max: 250. Always use first: N to limit results.

Filtering Reference

Comparators: eq, neq, in, nin, lt, lte, gt, gte, contains, startsWith, containsIgnoreCase

Combine filters with or: [...] for OR logic (default is AND within a filter object).

Typical Workflow

Query teams to get team IDs and keys
Query workflow states for target team to get state UUIDs
List or search issues to find what needs work
Create issues with team ID, title, description, priority
Update status by setting stateId to the target workflow state
Add comments to track progress
Mark complete by setting stateId to the team's "completed" type state

Rate Limits

5,000 requests/hour per API key
3,000,000 complexity points/hour
Use first: N to limit results and reduce complexity cost
Monitor X-RateLimit-Requests-Remaining response header

Important Notes

Always use terminal tool with curl for API calls — do NOT use web_extract or browser
Always check the errors array in GraphQL responses — HTTP 200 can still contain errors
If stateId is omitted when creating issues, Linear defaults to the first backlog state
The description field supports Markdown
Use python3 -m json.tool or jq to format JSON responses for readability

one-three-one-rule

Structured decision-making framework for technical proposals and trade-off analysis. When the user faces a choice between multiple approaches (architecture decisions, tool selection, refactoring strategies, migration paths), this skill produces a 1-3-1 format: one clear problem statement, three distinct options with pros/cons, and one concrete recommendation with definition of done and implementation plan. Use when the user asks for a "1-3-1", says "give me options", or needs help choosing between competing approaches.
