Linear

Use this skill when the user asks about Linear issues, tickets, projects, cycles, or their team's work tracking — finding issues, checking status, filing a bug, leaving a comment, or updating an issue.

This is an OAuth connector. The resolved user's Linear token already lives on your computer as an environment variable (the way a logged-in CLI's cached credential would):

  • $VAULT_TOKEN_API_LINEAR_APP — for api.linear.app

Linear's API is GraphQL at https://api.linear.app/graphql. Pass the token as a bearer header (-H "Authorization: Bearer $VAULT_TOKEN_API_LINEAR_APP"). Do not ask the user for a token, log it, or use another principal's credential.

If the variable is empty or the API returns 401/400 (authentication), tell the user they need to connect Linear (Connectors page) and stop — don't guess at issue data.

Find / read issues

Query issues by text, assignee, or state:

curl -sS -X POST 'https://api.linear.app/graphql' \
  -H "Authorization: Bearer $VAULT_TOKEN_API_LINEAR_APP" \
  -H 'content-type: application/json' \
  --data '{"query":"{ issues(first: 20, filter: { title: { containsIgnoreCase: \"login\" } }) { nodes { identifier title state { name } assignee { name } url } } }"}'

Read one issue by id/identifier:

curl -sS -X POST 'https://api.linear.app/graphql' \
  -H "Authorization: Bearer $VAULT_TOKEN_API_LINEAR_APP" \
  -H 'content-type: application/json' \
  --data '{"query":"{ issue(id: \"ENG-123\") { identifier title description state { name } assignee { name } url comments { nodes { body user { name } } } } }"}'

Keep issue identifiers and urls in your answer so claims can be traced.

To create or assign an issue you usually need a team id — list them once:

curl -sS -X POST 'https://api.linear.app/graphql' \
  -H "Authorization: Bearer $VAULT_TOKEN_API_LINEAR_APP" \
  -H 'content-type: application/json' \
  --data '{"query":"{ teams(first: 100) { nodes { id key name } pageInfo { hasNextPage endCursor } } }"}'

Linear paginates every list: if pageInfo.hasNextPage is true, re-query with after: "<endCursor>" — never conclude a team or issue doesn't exist from one page.

Writes require approval

Creating an issue, commenting, or changing state is a write. Prepare the exact mutation, summarize what it will create/change (team, title, target issue), and ask for approval before running it.

After approval, create an issue:

curl -sS -X POST 'https://api.linear.app/graphql' \
  -H "Authorization: Bearer $VAULT_TOKEN_API_LINEAR_APP" \
  -H 'content-type: application/json' \
  --data '{"query":"mutation($input: IssueCreateInput!) { issueCreate(input: $input) { success issue { identifier url } } }","variables":{"input":{"teamId":"TEAM_ID","title":"Login button misaligned on mobile","description":"Reported by a user; repro on iOS Safari."}}}'

Add a comment to an existing issue:

curl -sS -X POST 'https://api.linear.app/graphql' \
  -H "Authorization: Bearer $VAULT_TOKEN_API_LINEAR_APP" \
  -H 'content-type: application/json' \
  --data '{"query":"mutation($input: CommentCreateInput!) { commentCreate(input: $input) { success comment { url } } }","variables":{"input":{"issueId":"ISSUE_UUID","body":"Fixed in the latest deploy."}}}'

Always report the resulting issue/comment identifier and url.
