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

1. Get a personal API key from Linear Settings > Account > Security & access > Personal API keys (URL: https://linear.app/settings/account/security). Note: the org-level Settings > API page only shows OAuth apps and workspace-member keys, not personal keys.
2. Set LINEAR_API_KEY in your environment (via fetih 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:

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

Python helper script (ergonomic alternative)

For faster one-liners that don't need hand-written GraphQL, this skill ships a stdlib Python CLI at scripts/linear_api.py. Zero dependencies. Same auth (reads LINEAR_API_KEY).

SCRIPT=$(dirname "$(find ~/.fetih -path '*skills/productivity/linear/scripts/linear_api.py' 2>/dev/null | head -1)")/linear_api.py

python3 "$SCRIPT" whoami
python3 "$SCRIPT" list-teams
python3 "$SCRIPT" get-issue ENG-42
python3 "$SCRIPT" get-document 38359beef67c      # fetch a doc by slugId from the URL
python3 "$SCRIPT" raw 'query { viewer { name } }'

All subcommands: whoami, list-teams, list-projects, list-states, list-issues, get-issue, search-issues, create-issue, update-issue, update-status, add-comment, list-documents, get-document, search-documents, raw. Run with --help for flags.

Use the script when: you want a quick answer without crafting GraphQL. Use curl when: you need a query the script doesn't wrap, or you want to compose filters inline.

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

    "variables": {
      "input": {
        "name": "Q2 Auth Overhaul",
        "description": "Replace legacy auth with OAuth2 and PKCE",
        "teamIds": ["TEAM_UUID"]
      }
    }
  }' | python3 -m json.tool

Documents

Linear Documents are prose docs (RFCs, specs, notes) stored alongside issues. They have their own documents root query and document(id:) single-fetch.

Document URLs and slugId

Document URLs look like:

https://linear.app/<workspace>/document/<slug>-<hexSlugId>

The trailing hex segment is the slugId. Example: https://linear.app/yourorg/document/rfc-fetih-permission-gateway-discord-38359beef67c → slugId is 38359beef67c.

Important schema detail: the Markdown body is in the content field. The ProseMirror JSON is in contentState (not contentData — that field does not exist and the API returns 400).

Fetch a document by slugId

document(id:) only accepts UUIDs. To fetch by the URL's hex slug, filter the collection:

curl -s -X POST https://api.linear.app/graphql \
  -H "Authorization: $LINEAR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "query($s: String!) { documents(filter: { slugId: { eq: $s } }, first: 1) { nodes { id title content contentState slugId url creator { name } project { name } updatedAt } } }", "variables": {"s": "38359beef67c"}}' \
  | python3 -m json.tool

Or via the Python helper:

python3 scripts/linear_api.py get-document 38359beef67c

Fetch a document by UUID

curl -s -X POST https://api.linear.app/graphql \
  -H "Authorization: $LINEAR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "{ document(id: \"11700cff-b514-4db3-afcc-3ed1afacba1c\") { title content url } }"}' \
  | python3 -m json.tool

List recent documents

curl -s -X POST https://api.linear.app/graphql \
  -H "Authorization: $LINEAR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "{ documents(first: 25, orderBy: updatedAt) { nodes { id title slugId url updatedAt project { name } } } }"}' \
  | python3 -m json.tool

Search documents by title

Linear's schema has no searchDocuments root. Use a title-substring filter instead:

curl -s -X POST https://api.linear.app/graphql \
  -H "Authorization: $LINEAR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"query": "{ documents(filter: { title: { containsIgnoreCase: \"RFC\" } }, first: 25) { nodes { title slugId url } } }"}' \
  | python3 -m json.tool

Pagination

Linear uses Relay-style cursor pagination:

# 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

1. Query teams to get team IDs and keys
2. Query workflow states for target team to get state UUIDs
3. List or search issues to find what needs work
4. Create issues with team ID, title, description, priority
5. Update status by setting stateId to the target workflow state
6. Add comments to track progress
7. 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
