A tool for managing Linear issues, projects, and teams through Linear's GraphQL API, which is a structured interface for sending and receiving data.

Use it to create, update, search, and organize issues and projects, inspect teams, and move work through Linear's workflow states.

It lets an assistant organize development work without requiring a separate integration server or manual issue editing.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00043	$0.03214
Opus 5	$0.00022	$0.01607
Sonnet 5	$0.00009	$0.00643
Haiku 4.5	$0.00004	$0.00321

Security

Grade A, and why

linear scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 298 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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:

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

Common Queries

Get current user

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

List teams

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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
