arthur-skills-upgrade skillA
arthur-skills-upgrade is agent-read markdown (skill) from arthur-ai/arthur-engine: Upgrade locally installed arthur-onboard-* and arthur-skills-upgrade skills to the latest version from GitHub main branch. Checks version fields, reports stale skills, and updates in place after confirmation..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Upgrade Arthur Onboarding Skills Check locally installed `arthur-onboard-*` and `arthur-skills-upgrade` skills for updates and upgrade any that are behind the latest version on GitHub main. --- ## Step 1 — Find installed skills ```bash echo "=== Global install (~/.claude/skills/) ===" ls -d ~/.claude/skills/arthur-onboard-* ~/.claude/skills/arthur-skills-upgrade 2>/dev/null || echo "(none)" echo "" echo "=== Project install (.claude/skills/) ===" ls -d .claude/skills/arthur-onboard-* .claude/skills/arthur-skills-upgrade 2>/dev/null || echo "(none)" ``` Collect all found paths. If none are found in either location, tell the user no `arthur-onboard-*` or `arthur-skills-upgrade` skills are installed and show the install command from the README. --- ## Step 2 — Check versions For each installed skill directory, extract the local version and compare against GitHub main. Also load `~/.claude/arthur-skills-skip-versions.txt` (format: one `skill_name=version` per line) to suppress prompts for versions the user has previously chosen to skip. ```bash BASE="https://raw.githubusercontent.com/arthur-ai/arthur-engine/main/integrations/claude-code-skills/arthur-onboard" …
