Preview Execution monitoring

We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

About

Antigravity Workflows

Use this skill to turn a complex objective into a guided sequence of skill invocations.

When to Use This Skill

Use this skill when:

  • The user wants to combine several skills without manually selecting each one.
  • The goal is multi-phase (for example: plan, build, test, ship).
  • The user asks for best-practice execution for common scenarios like:
  • Shipping a SaaS MVP
  • Running a web security audit
  • Building an AI agent system
  • Implementing browser automation and E2E QA

Workflow Source of Truth

Read workflows in this order:

  1. docs/WORKFLOWS.md for human-readable playbooks.
  2. data/workflows.json for machine-readable workflow metadata.

How to Run This Skill

  1. Identify the user's concrete outcome.
  2. Propose the 1-2 best matching workflows.
  3. Ask the user to choose one.
  4. Execute step-by-step:
  • Announce current step and expected artifact.
  • Invoke recommended skills for that step.
  • Verify completion criteria before moving to next step.
  1. At the end, provide:
  • Completed artifacts
  • Validation evidence
  • Remaining risks and next actions

Default Workflow Routing

  • Product delivery request -> ship-saas-mvp
  • Security review request -> security-audit-web-app
  • Agent/LLM product request -> build-ai-agent-system
  • E2E/browser testing request -> qa-browser-automation

Copy-Paste Prompts

Use @antigravity-workflows to run the "Ship a SaaS MVP" workflow for my project idea.
Use @antigravity-workflows and execute a full "Security Audit for a Web App" workflow.
Use @antigravity-workflows to guide me through "Build an AI Agent System" with checkpoints.
Use @antigravity-workflows to execute the "QA and Browser Automation" workflow and stabilize flaky tests.

Limitations

  • This skill orchestrates; it does not replace specialized skills.
  • It depends on the local availability of referenced skills.
  • It does not guarantee success without environment access, credentials, or required infrastructure.
  • For stack-specific browser automation in Go, go-playwright may require the corresponding skill to be present in your local skills repository.
