Output format

Output auto-detects: human-readable tables in a terminal, JSON when piped. Override with --format {human,json}.

lineark teams list                  # table in terminal
lineark teams list | jq .           # JSON when piped
lineark teams list --format json    # force JSON

LLM / AI agent setup

Add this to your LLM's context (e.g. CLAUDE.md, .cursorrules, system prompt):

We use the `lineark` CLI tool for communicating with Linear. Use your Bash tool
to call the `lineark` executable. Run `lineark usage` to see usage information.

lineark usage gives your agent a complete command reference in under 1,000 tokens.
