linear is agent-read markdown (skill) from openhands/extensions: Interact with Linear project management - query issues, update status, create tickets, and manage workflows using the Linear GraphQL API. Use when working with Linear tickets, sprints, or project tracking..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Linear
Windows PowerShell equivalents for the repeated Linear GraphQL `curl` and environment-variable snippets are in `references/windows.md`.
<IMPORTANT>
Before performing any Linear operations, check if the required environment variable is set:
```bash
[ -n "$LINEAR_API_KEY" ] && echo "LINEAR_API_KEY is set" || echo "LINEAR_API_KEY is NOT set"
```
If LINEAR_API_KEY is missing, ask the user to provide it before proceeding.
</IMPORTANT>
## Understanding Linear Identifiers
Linear uses two types of identifiers for issues:
- **Human-readable identifier** (e.g., `ALL-1234`): Displayed to users, used in search queries. This is the team key + number.
- **UUID** (e.g., `a1b2c3d4-e5f6-7890-abcd-ef1234567890`): Required for all mutations (update, comment, etc.). Returned as `id` in query results.
**Important workflow**: When working with issues, you must:
1. Search or query using the human-readable identifier
2. Extract the `id` (UUID) from the query result
3. Use the UUID in any mutation operations
## Authentication
All Linear API requests use GraphQL with the API key in the Authorization header:
```bash
curl -s -X POST https://api.linear.app/graphql \
…
Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
