Actionlint workflow (jeremylongshore/claude-code-plugins-plus-skills)
The Actionlint workflow from jeremylongshore/claude-code-plugins-plus-skills, explained and optimized by Latchkey.
CI health: C - fair
Point runs-on at Latchkey and get run de-duplication, job timeouts, self-healing for flaky steps, and up to 58% lower cost, applied automatically.
What it does
This is the Actionlint workflow from the jeremylongshore/claude-code-plugins-plus-skills repository, a real project running GitHub Actions. It is shown here with attribution under its MIT license.
Below, Latchkey shows a faster, safer version produced by its optimization engine.
The workflow
name: Actionlint
# Lints every .github/workflows/*.yml file for syntactically correct GitHub
# Actions YAML, valid event triggers, valid if: expressions, and valid action
# references. New gate per PR 2 of the new-track CI overhaul - the workflow
# split adds 6+ new YAML files, and the validators themselves need a gate.
#
# Fires only when workflow YAML changes.

What changed
- Run on Latchkey managed runners with one line (
runs-on), which apply the fixes below automatically and self-heal transient failures. This example useslatchkey-small; pick the runner size that fits the job. - Cancel superseded runs when a branch or PR gets a newer push.
- Add a job timeout so a hung step cannot burn hours of runner time.
What Latchkey heals here
This workflow has steps that commonly fail on transient issues (network, registries, flaky browsers). On Latchkey managed runners they are detected, retried, and self-healed instead of failing your build:
- Network fetches
This workflow runs 1 job per trigger. On Latchkey the same minutes cost up to 58% less than GitHub-hosted, with zero queue time.
