Create Ticket

Create Linear Ticket

Create a new Linear ticket using the linear CLI (schpet/linear-cli).

Supports two modes:

• Init mode (/create-ticket init): guides first-time setup of the linear CLI
• Create mode (/create-ticket ): creates a ticket from a quick description

Announce at start: "Creating a new Linear ticket..."

---

Customization Variables

| Variable | Description | Example | |---|---|---| | ` | Linear workspace slug (from linear auth whoami) | acme-corp | | | Linear team key (from linear team list) | ENG` |

These are determined interactively during init mode. No manual editing required.

---

Detect Mode

Read $ARGUMENTS:

• If $ARGUMENTS is exactly init, go to Init Mode (Steps 1-4).
• If $ARGUMENTS is empty, ask the user for a ticket title or whether they want to run init.
• Otherwise, go to Create Mode (Steps 5-9).

---

Init Mode

Announce at start: "Setting up the linear CLI for this project..."

Step 1: Check CLI Installation

Run which linear to check if the linear CLI is installed.

If not installed

Tell the user to install it:

brew install schpet/tap/linear

Alternative install methods:

• npm: npm install -g @schpet/linear-cli
• deno: deno install -A --reload -f -g -n linear jsr:@schpet/linear-cli
• Binaries: https://github.com/schpet/linear-cli/releases/latest

Wait for the user to confirm installation before continuing.

If installed

Print the version (linear --version) and continue.

Step 2: Check Authentication

Run linear auth whoami to check if the CLI is authenticated.

If not authenticated

Guide the user through authentication:

1. Create a Linear API key at https://linear.app/settings/account/security

• Scroll to "Personal API keys"
• Click "Create key", give it a label like "CLI"
• Copy the key (starts with lin_api_)

1. Tell the user to run linear auth login in their terminal

• This is an interactive command -- the user must run it themselves
• It will prompt for the API key and store it in the system keyring

After the user confirms they have logged in, verify by running linear auth whoami again.

If authenticated

Display the workspace and user info and continue.

Step 3: Configure Project

Check if a .linear.toml file exists in the project root.

If .linear.toml exists

Read it and verify it contains a team_id. Display the current config and continue.

If .linear.toml does not exist

Set up the project config:

1. Run linear team list to show all available teams.
2. Ask the user which team they want tickets created under. Present the team names and keys from the list output.
3. Run linear auth whoami to get the workspace slug.
4. Create a .linear.toml file in the project root with the chosen team:

workspace = ""
team_id = ""

For example, if the user picks a team with key ENG in workspace acme-corp:

workspace = "acme-corp"
team_id = "ENG"

Ask the user to confirm before writing the file.

Step 4: Verify Setup

Run a quick verification to confirm everything works end-to-end:

linear issue list -s todo

If successful

Announce that setup is complete:

Setup complete! You can now use /create-ticket  to create tickets.

If it fails

Display the error and suggest troubleshooting steps:

• Check linear auth whoami for auth issues
• Check .linear.toml for config issues
• Refer to https://github.com/schpet/linear-cli for documentation

---

Create Mode

Announce at start: "Creating a new Linear ticket..."

Step 5: Verify Prerequisites

Run linear auth whoami to confirm the CLI is authenticated.

• If not authenticated, tell the user to run /create-ticket init first and stop.
• If authenticated, continue.

Step 6: Parse Arguments

Use $ARGUMENTS as free-text input to derive ticket fields:

• Title: extract a concise, clean ticket title from the input. If the input is already a short phrase, use it as-is. If it is a longer description, summarize it into a clear title.
• Description: always generate a description with the two mandatory sections below. Every ticket must have both sections -- never create a ticket without them.

Description Format

The description must always contain these two markdown sections in this order:

## Background

## Definition of Done

- [ ] 
- [ ] 
- [ ] 

Background section rules

• Explain why this work is needed -- the context, motivation, or problem being solved.
• Derive it from the user's input. If the user provided enough context, write 1-3 sentences.
• If the user's input is too brief to write a meaningful background, ask a follow-up question before proceeding.
• Do not pad with filler. A single clear sentence is fine.

Definition of Done section rules

• List concrete, verifiable acceptance criteria as checkbox items (- [ ]).
• Derive criteria from what the user described. If the user said "set up monitoring", reasonable criteria are things like "dashboards created", "alerts configured", "alerts verified".
• Aim for 2-5 criteria. Each should be a clear pass/fail condition.
• Do not invent requirements the user did not imply. If you cannot infer at least 2 criteria from the input, ask the user a clarifying question to fill this in.

Rules

• Do not invent requirements the user did not mention or imply.
• Keep the title under 80 characters.
• Write the description in plain language, not corporate speak.
• If the input is too brief to produce both a meaningful Background and at least 2 Definition of Done criteria, ask a clarifying question before proceeding.
• Never create a ticket with an empty description.

Step 7: Confirm with User

Present the drafted ticket to the user for confirmation using the question tool:

• Show the title and full description (with both Background and Definition of Done sections)
• Options:
• "Create this ticket" -- proceed to create
• (custom answer -- the user can edit or cancel)

This is a safety step since we are creating a real ticket in Linear.

Step 8: Create the Ticket

Run the linear issue create command:

linear issue create -t "" -d ""

The description must include the ## Background and ## Definition of Done sections.

The CLI uses the team configured in .linear.toml, so no team flag is needed.

Step 9: Report Result

After the ticket is created, display:

• The ticket identifier (e.g., ENG-123)
• The ticket title
• The URL (run linear issue url or construct from the identifier)

Output format

Created -: 
URL: https://linear.app//issue/-
Status: Todo | Priority: Normal | Assignee: Unassigned

Important Notes

• The .linear.toml config determines which team tickets are created under. Run /create-ticket init to change the team.
• NEVER include secrets, API keys, tokens, passwords, or sensitive credentials in ticket titles or descriptions.
• NEVER read or expose the contents of auth credential files (e.g., ~/.config/linear/credentials.toml API key values).
• If linear auth whoami fails or the CLI is not installed, direct the user to /create-ticket init rather than attempting manual workarounds.
• If the user provides context that contains sensitive data (IPs, keys, tokens), redact them before including in the ticket.
