Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00034 | $0.00636 |
| Opus 5 | $0.00017 | $0.00318 |
| Sonnet 5 | $0.00007 | $0.00127 |
| Haiku 4.5 | $0.00003 | $0.00064 |
Grade A, and why
antigravity-workflows scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to antigravity-workflows — 23 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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:
docs/WORKFLOWS.mdfor human-readable playbooks.data/workflows.jsonfor machine-readable workflow metadata.
How to Run This Skill
- Identify the user's concrete outcome.
- Propose the 1-2 best matching workflows.
- Ask the user to choose one.
- Execute step-by-step:
- Announce current step and expected artifact.
- Invoke recommended skills for that step.
- Verify completion criteria before moving to next step.
- At the end, provide:
- Completed artifacts
- Validation evidence
- Remaining risks and next actions

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.
Use @antigravity-workflows to execute the "Design a DDD Core Domain" workflow for my new service.
Limitations
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

antigravity-workflows is a skill published in the GitHub repository lucaspmarie-a11y/claude-skills-vault (5 stars, last pushed 3mo ago), licensed MIT. It adds 34 tokens to every session and 636 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to antigravity-workflows, differing in 23 lines, and is treated as a copy.
