Fine to try. Some of what it can do is expected: a coding skill usually runs build and test commands.

Smoke test the Agent Builder feature branch end-to-end against a hermetic project scaffolded by the skill (linked to the current worktree). Covers workspace reconciliation, stored agents/skills CRUD, ownership, visibility, stars, registry/library Copy flow, picker allowlists, model policy, RBAC role gating, role impersonation UI, builder defaults, infrastructure diagnostics, channels, and Studio + Agent Builder UI. Trigger when validating the agent-builder feature branch, PRs that touch package…

Works with any agent that supports SKILL.md skills.

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'builder-smoke-test' ] || [ -L ~/.agents/skills/'builder-smoke-test' ]; then echo 'A skill folder named builder-smoke-test already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/mastra-ai/mastra' "$d" && git -C "$d" checkout --quiet '43d1e9c16d6681a66636e318c34118597911f7c5' -- '.claude/skills/builder-smoke-test' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/builder-smoke-test' ~/.agents/skills/'builder-smoke-test' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'builder-smoke-test' ~/.claude/skills/'builder-smoke-test' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
