sling CLI

sling is StarSling's agent-first CLI for GitHub Actions. It answers questions about live CI data — one run, one job, one attempt, or an account's runner-minutes — from StarSling's control plane, with structured JSON on stdout and a stable exit-code table. In this release it is read-only: it reads and analyzes, and there is no sling command that changes anything in GitHub.

This skill's job is picking the right tool per request. Live question about a run, a job, or spend → sling. Anything that changes CI state → gh. A repo-wide audit of workflow files → hand off to the audit skill that owns it and stop. Do not invent a sling subcommand for something sling does not do; the command surface is the complete list.
