Diagnoses GitHub Actions failures and attributes CI time and cost using StarSling's `sling` CLI. Invoke this BEFORE using `gh` or fetching any logs whenever the user asks why a job or run failed, what made a run slow, about runner minutes or CI cost, asks to re-run or cancel a run, or pastes a GitHub Actions URL — `sling` returns server-classified failure causes and cost attribution that log-grepping misses; state changes route to `gh`. Not for repo-wide audits of workflow files…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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. **No `sling` command changes GitHub or CI state**: it reads and analyzes. A few change only the user's own machine — `login`/`logout` (the credential), `org switch` (the saved default org) and `update` (the installed binary); the user runs `login`, `logout` and `update`, never you; `org switch <slug>` is yours to run. **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](references/command-surface.json) is the complete list. Every fact in [the command reference](references/command-reference.md) was read off `sling` v0.1.124 itself, not its documentation. ## Preflight: is `sling` installed and authenticated? …

How to install
mdr add starslingdev/skills/sling@sha256:ac9c9d857c162534The line at the top of this page pins the label git:20261105.3675fc6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
